This manual describes the installation and operation of the Sequoia Model 2160 catalytic-equipped wood heater. This heater meets the U.S. Envi-

ronmental Protection Agency’s emission limits for wood heaters sold after July 1, 1990. Under specic test conditions this heater has been shown

to deliver heat at a rate ranging from 10,400 to 31,700 Btu’s/Hr. A Sequoia equipped with an 8” (200mm) ue collar also burns coal. Coal-burning in

the Sequoia is not allowed with the 6” (150mm) ue collar. In addition, the catalytic combustor must be removed before burning coal. In addition to

directions on installation and operation, this manual includes directions on maintenance and assembly.

We recommend that you hire a professional solid fuel stove installer to install your stove, or to advise you on the installation should you attempt to

install it yourself.

The Sequoia has been tested and is listed by Warnock Hersey of Middleton, Wisconsin. The test standards for the Sequoia equipped with a 8” (200

mm) ue collar are ANSI/UL 1482 and ANSI/UL 737 for the United States and CAN/CSA-B366.2 for Canada. The Sequoia equipped with a 6” (150

mm) ue collar is not tested to ANSI/UL 737 and should not be used in conjunction with replace screen. The Sequoia is not listed for installation in

mobile homes.

Proposition 65 Warning: Fuels used in gas, woodburn-

ing or oil red appliances, and the products of combus-

tion of such fuels, contain chemicals known to the State

of California to cause cancer, birth defects and other

reproductive harm.

SAFETY NOTICE: IF YOUR SEQUOIA HEATER IS NOT

PROPERLY INSTALLED, OPERATED AND MAINTAINED,

A HOUSE FIRE MAY RESULT. FOR SAFETY, FOLLOW

ALL INSTALLATION, OPERATION AND MAINTENANCE

DIRECTIONS. CONTACT LOCAL BUILDING OFFICIALS

ABOUT RESTRICTIONS AND INSTALLATION INSPEC-

TION REQUIREMENTS IN YOUR AREA.

Before you begin the installation, review your plans to

conrm that:

• Your stove and chimney connector will be far enough

from combustible materials to meet all clearance require-

ments.

• The oor protector is large enough and is constructed

properly to meet all requirements.

• You have obtained all necessary permits from local

authorities.

Your local building ofcial is the nal authority for approving

your installation as safe and for determining that it meets

local and state codes.

The metal label permanently attached to the back of the

stove indicates that it has been tested to current UL and

ULC standards, and gives the name of the testing labora-

tory. Clearance and installation information is also printed

on the label. Local authorities generally will accept the label

as evidence that, when the stove is installed according to

the information on the label and in this manual, the instal-

lation meets codes and can be approved.

Codes vary in different areas, however. Before starting

the installation, review your plans with the local building

authority. Your local dealer can provide any additional

information needed.

For any unresolved questions about installation, refer

to the National Fire Protection Association’s publication

ANSI/NFPA 211-1988 Standard For Chimneys, Fireplaces,

Vents and Solid Fuel Burning Appliances. In Canada, the

equivalent publication is CSA CAN-B365, Installation Code

for Solid Fuel Burning Appliances and Equipment. These

standards are the basis for many national codes. They

are nationally recognized and are accepted by most local

authorities. Your local dealer or your local building ofcial

may have a copy of these regulations.

Important: Failure to follow these installation instructions

may result in a dangerous situation, including a chimney

or house re. Follow all instructions exactly, and do not

allow makeshift compromises to endanger property and

personal safety.

Chimney Types

Your Sequoia must be connected to a sound masonry chim-

ney that meets local codes, a relined masonry chimney that

meets local codes, or to an approved prefabricated metal

chimney. Whatever kind you use, the chimney and chimney

connector must be in good condition and kept clean.

Masonry Chimneys

If you use an existing masonry chimney, it must be inspected

to ensure safe condition before the stove is installed. Your

local professional chimney sweep, building inspector, or re

department ofcial will be able either to make the inspection

or to direct you to someone who can.

An inspection of the chimney must conrm that it has a lin-

ing. Do not use an unlined chimney. The chimney should

also be examined for cracks, loose mortar, other signs of

deterioration, and blockage. Repair any defects before the

chimney is used with your stove.

Unused openings in an existing masonry chimney must

be sealed with masonry to the thickness of the chimney

wall, and the chimney liner should be repaired. Openings

sealed with pie plates or wallpaper are a hazard and should

be sealed with mortar or refractory cement. In the event

of a chimney re, ames and smoke may be forced out of

these unused thimbles.

The chimney should be thoroughly cleaned before use.

A newly-built masonry chimney must conform to the

standards of your local building code or, in the absence

of a local code, to a recognized national code. Masonry

chimneys must be lined, either with code-approved ma-

sonry or pre-cast refractory tiles, stainless steel pipe, or

a code-approved, “poured-in-place” liner. The chimney’s

clean-out door must seal tightly.

Prefabricated Chimneys

A prefabricated metal chimney must be one tested and

listed for use with solid-fuel burning appliances to the

High-Temperature (H.T.) chimney Standard UL-103-1985

(2100°F.) for the United States, and High Temperature

(650°C) Standard ULC S-629 for Canada.

WARNING: Do not use double-wall chimney connec-

tors with the Sequoia unless they have been speci-

cally tested and listed for use with this appliance.

Use of double-wall chimney connectors that have

not been tested and listed for use with the Sequoia

may result in temperatures exceeding the limits

established by the test standards ANSI/UL-1482 or

ULC S627. A potential hazard may result, including

a house re.

DO NOT CONNECT THIS UNIT TO A CHIMNEY

FLUE SERVING ANOTHER APPLIANCE.

Chimney Size

A Sequoia with an 8” (203 mm) ue collar is approved for

venting into a masonry chimney with a nominal ue size

of 8” x 8” (203 x 203 mm), and into a round ue size of 8”

(203 mm). A Sequoia with a 6” (152 mm) ue collar is ap-

proved for venting into a masonry chimney with a nominal

ue size of 8” x 8” (203 x 203 mm), and into a round ue

size of 6” (152 mm).

Whatever the ue collar size, a Sequoia may be vented

into larger chimneys as well. However, chimneys with larger

liners and particularly those with liners larger than 8” x 12”

(203 x 305 mm) may experience rapid cooling of smoke and

reduction in draft, especially if they are located outside the

home. These large chimneys may need to be insulated or

have their ues relined for proper stove performance.

Accessories to help make the connection between stain-

less steel chimney liners and your Sequoia are available

through your local dealer.

Chimney Height

Altitude affects chimney performance. Refer to the chart

below for suggested chimney heights at various altitudes.

Chimney height should be measured form the ue collar

to the top of the chimney. The recommended minimum

chimney height is 16’ (4.9 m).

Chimney Connector Guidelines

The chimney connector is the single-wall pipe that connects

the stove to the chimney. The chimney itself is a masonry

or prefabricated structure that encloses the ue. Chimney

connectors are used only to make the connection from the

stove to the chimney.

Do not pass the chimney connector through a combustible

wall or ceiling, or through an attic, a closet or any similar

concealed space. If passage through a combustible wall is

unavoidable, follow the recommendations in the following

section on Wall Pass-Throughs.

Use chimney connector that is 24 gauge steel or heavier,

with a diameter of 8” (203 mm) for an 8” (203 mm) ue

collare or 6” (152 mm) for the 6” (152 mm) ue collar.

Install the chimney connector not less than 18” (457 mm)

from the ceiling. Keep the passage as short and direct as

possible, with no more than two 90° turns. Slope horizontal

runs of connectors upward 1/4” per foot (20 mm per meter)

going from the stove toward the chimney. The recom-

mended maximum length of horizontal run is 3’ (914 mm),

and the total length of chimney connector should be no

longer than 8’ (2.4 m).

In cathedral ceiling installations, extend the prefabricated

chimney downward to within 8’ (2.4 m) of the stove. The

entire chimney connector should be exposed and acces-

sible for inspection and cleaning.

Do not use galvanized chimney connector; it cannot

withstand the high temperatures that can be reached by

smoke and exhaust gases and it may release toxic fumes

under high heat.

Assembling the Chimney Connector

SAFETY NOTE: Always wear gloves and safety goggles

when drilling, cutting or joining sections of chimney

connector.

• Beginning at the ue collar of the stove, assemble the

chimney connector. Insert the rst crimped end into the

stove’s ue collar, and keep each crimped end pointing

toward the stove. Using the holes in the ue collar as

guides, drill 1/8” (3mm) holes in the bottom of the rst

section of chimney connector and secure it to the ue

collar with three #10 x 1/2” sheet metal screws.

• Secure each joint

between sections

of chimney con-

nector, includ-

ing telescoping

joints, with at

least three sheet

metal screws.

The predrilled

holes in the top

of each section

of chimney con-

nector serve as

guides when you

drill 1/8” (3 mm)

holes in the bot-

tom of the next

section.

• Secure the chim-

ney connector to the chimney. Instructions for various

installations follow.

• Be sure the installed stove and chimney connector are

correct distances from nearby combustible material.

NOTE: Special slip pipes and thimble sleeves that form

telescoping joints between sections of chimney connector

are available to simplify installations. They can eliminate

the need to cut individual connector sections. Consult your

local dealer about these special pieces.

Securing the Connector

to a Prefabricated Chimney

Follow the installation instructions of the chimney manufac-

turer exactly as you install the chimney. The manufacturer

of the chimney will supply the accessories to support the

chimney, either from the roof of the house, at the ceiling of

the room where the stove is installed, or from an exterior

wall.

Special adapters are available from your local dealer to

make the connection between the prefabricated chimney

and the chimney connector. The top of such adapters at-

tach directly to the chimney or to the chimney’s ceiling sup-

port package, while the bottom of the adapter is screwed

to the chimney connector.

These adapters are designed so the top end will t outside

the inner wall of the chimney, and the bottom end will t

inside the rst section of chimney connector. Any soot or

creosote falling from the inner walls of the chimney will stay

inside the chimney connector.

Securing the Connector

to a Masonry Chimney

The Sequoia may be connected to either a freestanding

masonry chimney or a masonry replace chimney.

Freestanding Installations

If the chimney connector must pass through a combustible

wall to reach the chimney, follow the recommendations in

the wall pass-through section that follows.

The opening through the chimney wall to the ue (the

“breech”) must be lined with either a ceramic or metal

cylinder, called the “thimble”, which is securely cemented

in place. (Fig. 6) Most chimney breeches incorporate

thimbles, but check to be sure the t is snug and the joint

between thimble and chimney wall rmly cemented.

A special piece called the “thimble sleeve,” slightly smaller

in diameter than the standard connector and most thimbles,

will ease the removal of the chimney connector system for

inspection and cleaning. (Fig. 7) Thimble sleeves should

be available from your local dealer.

To install a thimble sleeve, slide it into the breech until it is

ush with the inner ue wall. Do not extend it into the actual

ue passage, as that could interfere with the draft.

The thimble sleeve should protrude 1-2” (25-50 mm) into

the room. Use furnace cement and thin gasketing to seal

the sleeve in place in the thimble. Secure the chimney

connector to the outer end of the sleeve with sheet metal

screws.

Fireplace Installations -

Above the Fireplace

In this installation, the chimney connector rises from the

stove, turns ninety degrees, and goes back into the re-

place chimney. The liner of the replace chimney should

extend at least to the point at which the chimney connector

enters the chimney. Follow all the guidelines for installing

a chimney connector into a freestanding masonry chimney,

and pay special attention to these additional points:

• Check the stove and chimney connector clearances to

combustible mantel or trim materials. Use the neces-

sary combination of mantel, trim, and connector heat

shields to provide the required clearances. (Fig. 8)

• Double-check connector clearance from the ceiling.

• The replace damper must be closed and sealed to

prevent room air from being drawn up the ue, reducing

the draft. However, it must be possible to re-open the

damper to inspect or clean the chimney.

Fireplace Installations -

Through the Fireplace

If the height of your replace opening is at least 30” (762

mm), you may install a Sequoia through the opening using

a “positive connection” kit available from your local dealer.

These kits ensure a tight t between the stove ue collar

and the chimney ue.

Fireplace installations, whether connected to the ue above

or through the replace opening, have special clearance

requirements to adjacent trim and the mantel. You will nd

the required safe clearances for Sequoia replace instal-

lation on Page 10.

Floor protection requirements also apply to replace instal-

lation. Be sure to review the oor protection requirements

Wall Pass-Throughs

Whenever possible, design your installation so the connec-

tor does not pass through a combustible wall. If you must

use a wall pass-through in your installation, check with

your building inspector before you begin and construct it

in accordance with local building codes. Also check with

the chimney connector manufacturer for any specic re-

quirements.

Accessories are available for use as wall pass-throughs.

If using one of these, make sure it has been tested and

listed for use as a wall pass-through.

In the United States, the national Fire Protection Associa-

tion (NFPA) has established guidelines for passing chim-

ney connectors through combustible walls. Many building

code inspectors follow these guidelines when approving

installations.

Figure 10 shows one NFPA-recommended method. All

combustible material in the wall is cut away a sufcient dis-

tance from the single-wall connector to provide the required

12” (305mm) clearance for the connector. Any material

Floor Protection

A tremendous amount of heat radiates from the bottom

plate of your Sequoia stove. The oor area directly under

and around the stove will require protection from radiant

heat as well as from stray sparks or embers that may

escape the rebox.

Heat protection is provided through the use of a Dutchwest

Bottom Heat Shield. Spark and ember protection must be

provided by a oor protector constructed with noncombus-

tible material as specied.

Most installations will require that the bottom heat shield be

attached. Only when the stove is placed on a completely

noncombustible surface such as unpainted concrete over

earth may be used without the heat shield.

Even when the bottom heat shield is installed, you must

provide special protection to the oor beneath. For instal-

lation with the heat shield attached, use a noncombustible

oor protector such as 1/4” non-asbestos mineral board or

equivalent, or 24 gauge sheet metal. The oor protector

may be covered with a decorative noncombustible material

if desired. Do not obstruct the space under the heater.

Protection requirements vary somewhat between the United

States and Canada as follows:

U.S. Installations: The oor protector is required under

the stove and must extend at least 16” from the front and

left (loading door) side of the stove, and at least 6” from

the right side and rear. (Fig. 12) It must also extend un-

der the chimney connector and 2” to either side. Refer to

Figure 12 for minimum noncombustible oor protection

dimensions.

To meet these requirements, a oor protector must be at

least 48” wide and 42” deep.

In Canada: a noncombustible oor protector is required

under the heater also. The oor protector must extend 18”

(457 mm) from the front and left (loading door) side of the

stove, and at least 6” (150 mm) from the right side and rear.

Material

used to close up the opening must be noncombustible.

Three other methods are also approved by the NFPA.

These are:

• Using a section of double-wall chimney with a 9” clear-

ance to combustibles.

• Placing a chimney connector pipe inside a ventilated

thimble, which is then separated from combustibles by

6” of berglass insulating material.

• Placing a chimney connector pipe inside a section of

8” diameter, solid-insulated, factory-built chimney, with

2” of air space between the chimney section and com-

bustibles.

In Canada, the Canadian Standards Association has estab-

lished different guidelines. Figure 11 shows one method,

in which all combustible material in the wall is cut away to

provide the required 18” (457 mm) clearance for the con-

nector. The resulting space must remain empty. A ush-

mounted sheet metal cover may be used on one side only.

If covers must be used on both sides, each cover must be

mounted on noncombustible spacers at least 1” (25 mm)

clear of the wall. Your local dealer or your local building

inspector can provide details of other approved methods

of passing a chimney connector through a combustible

wall. In Canada, this type of installation must conform to

CAN/CSA-B365, Installation Code for Solid Fuel Burning

Appliances and Equipment.

NOTE: Do not vent your Sequoia into a factory-built (zero-

clearance) replace. These appliances and their chimneys

are specically designed as a unit for use as replaces.

It may void the listing or be hazardous to adapt them to

any other use.

DO NOT CONNECT THE HEATER TO ANY AIR DISTRI-

BUTION DUCT OR SYSTEM.

noncombustible oor protection dimensions.

In addition, a pad measuring 18” (457 mm) wide by 24” (610

mm) long consisting of 1/2” (13 mm) thick rigid insulation

board with a K value of .23 or less (such as Carborundum

Duraboard LD or Manville Ceraform 126) is also required;

it must be centered and must extend 16” (406 mm) in front

of and 8” (203mm) under the unit. The oor protector may

be covered with a noncombustible decorative material if

desired. Do not obstruct the space under the heater.

To meet these requirements, a oor protector must be 50”

(1270 mm) wide and 44” (1118 mm) deep.

Due to the side loading door, oor protector requirements

call for more protection on the left side than on the right. If

you wish a more balanced look, increase the other side of

the hearth as well. Do not reduce side protection under

any circumstances.

NOTE: In both the United States and Canada, no bottom

heat shield is required when the optional pedestal base is

used in place of the standard legs.

Floor Protection for Fireplace

Do not assume that your replace hearth is completely

noncombustible. Many replace hearths do not satisfy the

“completely noncombustible” requirement because the brick

or concrete in front of the replace opening is supported by

heavy wood framing. Because heat passes readily through

brick or concrete, it can easily pass through to the wood.

As a result, such replace hearths can be a re hazard and

are considered a combustible oor. (Fig. 13)

For all replace installations, follow the oor protection

guidelines described above. Keep in mind that many raised

hearths will extend less than the required clearance from the

front of the heater. In such cases, sufcient oor protection

as described above must be added in front of the hearth to

satisfy the minimum oor protector requirement from the

front of the stove: 16” (406 mm) in the United States and

18” (457 mm) in Canada.

Hearth rugs do not satisfy the requirement for oor protec-

tion as they are not re proof.

Fireplace installations also have special clearance require-

ments to the side walls, side decorative trim and replace

mantel. Refer to the information on replace and mantel

trim shields in this section.

Keep the Stove a Safe Distance

from Surrounding Materials

Both a stove and its chimney connector radiate heat in all

directions when operating. A safe installation requires that

adequate clearance be maintained between the stove and

nearby combustible materials to ensure that such materials

do not overheat.

Clearance is the distance between either your stove or

chimney connector, and nearby walls, oors, the ceiling,

and any other xed combustible surface. Keep furnishings

and other combustible materials away from the stove as

well. In general, a distance of 48” (1220 mm) must be main-

tained between the stove and moveable combustible items

such as drying clothes, furniture, newspapers, rewood,

etc. Keeping those clearance areas empty assures that

nearby surfaces and objects will not overheat.

Safe Ways to Reduce Clearances

Your stove has specic clearance requirements that have

been established through careful research and testing to

UL and ULC standards.

Clearance requirements have been established to meet

every installation possibility, and they involve the combina-

tion of basic variables:

• When the stove has no listed heat shield

• When the stove has a listed heat shield

Fireplace Installations

A replace installation requires special clearance between

the side of the stove and the right and left walls, between

the side of the stove and the decorative side trim on the

replace face, and between the top of the stove and the

mantel.

Ventilated, noncombustible shields installed on

noncombustible spacers 1” (25 mm) away from the

combustible surface may be used to reduce clearances.

A mantel shield for the Sequoia must be at least 48” (1220

mm) long, centered over the stove. Side trim shields must

extend the full length of the trim.

In addition, a replace installation must observe the oor

protection guidelines discussed previously.

The charts and illustrations that follow depict all

the clearances required for the various installation

congurations of the Sequoia.

• When the wall has no heat shield

• When the wall has a heat shield

In general, the greatest clearance is required when you

locate a stove with no heat shield near a wall with no heat

shield. The least clearance is required when both the

stove and the wall have heat shields. Reducing a stove

clearance may require a listed heat shield on the chimney

connector as well, or a double-wall connector.

Clearances may be reduced only by means approved

by the regulatory authority and in accordance with the

clearances listed in this manual. The charts and sample

installations that follow list all the clearances required for

the various installation congurations of Sequoia.

Wall Shields

One way to reduce clearances is with a wall shield con-

structed of 24 gauge or heavier sheet metal, or of another

noncombustible material such as 1/2” (13 mm) insulation

board such as Durock

or Wonderboard

, or common brick

“laid on at,” with the 3¹⁄₂" (90 mm) side down.

Shields must be spaced out from the combustible surface

1" (25 mm) on noncombustible spacers, as in Figure 14.

The spacers should not be directly behind the stove or

chimney connector.

Air must be able to ow between the wall and the shield. At

least 50% of the bottom 1" (25 mm) of the shield must be

open, and the shield must be open at the top. (Fig. 14)

Unpack the Parts

Remove all loose parts from the rebox and the ash pan.

Check to make sure all the parts are included and intact.

You should have received:

• 1 fully assembled heater body, (with catalytic burner

installed in its chamber below the stove top)

• 4 legs

• 1 Installed ash pan containing:

• 1 Replacement Interam gasket, for combustor

• 1 Ceramic Handle, for use on the doors and damp-

• 1 Brass Handle, for use on dial dampers

• 1 bag of hardware used for assembly, including the

following:

• To attach the legs to the stove:

(4) 1/4-20 x 1” hex head bolts

(4) 1/4” washers

• For tightening the door latch:

(1) Allen wrench, 5/32”

• also...

(1) Spring, which t inside the square socket in

the iron part of the door handles, and will push the

handle off the stove in case you forget to remove

it after adjusting the dial dampers. This keeps the

handles from getting hot.

The hardware in the stove is in standard US sizes. Most

bolts are 1/4-20 and 7/16 heads.

If any parts are missing or damaged, immediately notify

your Dutchwest dealer for replacements. Do not install

your stove without having all necessary parts or by using

damaged parts.

Attach the Legs and Heat Shield*

Since you have already received delivery of your Sequoia,

you are aware of how heavy it is. To safely accomplish the

setup and installation of the Sequoia, you should have two

or more strong assistants to help move it.

Place the stove on its back on a soft surface such as a

couple of old blankets. Tilt it carefully. Protect surrounding

carpet with an old blanket or sheet.

First, loosely install a bottom heat shield bracket and leg to

each corner of the stove. Place a 1/4-20 x 1” bolt through

the unthreaded hole in the bracket so the bracket’s threaded

hole will extend below the leg. Position the leg, and fasten

it to the stove nger-tight with bolt. Repeat this step for

each of the four legs.

*Bottom heat shields are standard only on stoves sold in

Canada.

Assembly

Next, fasten the bottom heat shield to the brackets, adjust-

ing the legs as needed to make the shield t. Tighten the

shield securely, then use a wrench to tighten the leg bolts

rmly. Now raise the stove onto its legs.

Install the Fittings

To install the catalytic probe:

• Locate the hole in the top of stove.

• Insert a 1/4” drill bit in the hole and rotate it with your

ngers to clear a path for the probe through the fragile

refractory material.

• Insert the probe stem into the stove top and through the

prepared opening.

Your stove has been shipped with grate covers installed.

These must remain installed when burning wood, but should

be removed for burning coal.

The hardware in your stove is in standard US sizes. Most

bolts are 1/4”-20, with 7/16” heads. Some of the hex-head

bolts have metric heads. Use wither a 3/8” (10mm) wrench,

or an 8mm wrench or pliers if you are attaching a blower

to the stove.

The multipurpose brass handle will operate the two spin-dial

air controls, the doors and the stove damper.

Install Air Duct for Outside Air

If your installation will include outside air for combustion,

follow these directions for attaching the three inch duct to

the stove:

• Screw a #10 x 1/2” sheet metal screw into the duct.

Tighten the screw, then back it off two turns.

Dutchwest

• The outside air port on the back of the stove has a slot

at the 10:00 o’clock position. Align the screw in the duct

pipe with the slot and insert the pipe. Turn 1/4 turn,

clockwise. This locks the pipe securely in position.

The Sequoia Controls

Air Controls

The Sequoia has three air controls that regulate the amount

of air drawn into the stove. Generally, more air entering the

stove makes the re burn hotter and faster, while less air

prolongs the burn.

The Primary Air Control is the lever located on the upper

right side of the stove front and is the primary source of air

for starting and maintaining wood res. It is always closed

when burning coal. It opens when moved clockwise and

closes when moved counterclockwise.

The Combustor Air Control is located on the left side

of the stove, above the side loading door, and delivers

preheated air to a strategic internal site to aid catalytic

combustion when burning wood. This control is closed

completely when burning coal. Turn counterclockwise to

open and clockwise to close.

The Coal-only Air Control is positioned on the access

door to the ash drawer compartment. It is the air supply

for starting and maintaining coal res. This control must

be closed completely when burning wood. As with the

combustor air control, turn counterclockwise to open and

clockwise to close.

Damper Function

The Damper is operated by moving the small, square knob

on the left side of the stove. It has two positions: open, to

start or revive the re; and closed for greatest efciency

and heat. Using the multipurpose door handle, rotate the

damper knob counterclockwise to open the damper and

clockwise to close it.

The stove damper must be open when starting a re, when

reloading fuel (for a short time only), and when the side or

front doors of the stove are opened for any reason. It may

also be left open when burning coal whenever maximum

heat is needed.

the front door may be opened wide and an optional spark

screen, Part No. 0135, placed in the opening for safe,

Insert the Probe Thermometer into the access port (see

directions on Page 16) as a valuable guide that will tell

you when to open and close the stove damper, when to

increase or decrease the air supply, whether or not the

stove’s catalytic combustor is working properly when you

are burning wood, and when to add fuel.

Successful Wood Burning

Burning wood and coal is often said to be more of an art

than a science. You will easily master the art if you start by

using good, dry fuel and by understanding how the stove’s

air supply system operates.

Burn Only High-Quality Fuel

This heater is designed to burn natural wood only (or coal,

when the catalytic combustor has been removed and the

optional coal kit installed). Do not burn fuels other than

those for which this heater was designed. Never burn

pressure-treated wood, painted or stained wood, or glossy

newsprint.

High efciencies and low emissions are possible when

burning air-dried, seasoned woods as compared to soft-

woods or freshly cut hardwoods. Avoid burning “green”

wood that has not been properly seasoned.

The best hardwood fuels include oak, maple, beech, ash,

and hickory that has been split, stacked, and air-dried out-

side under cover for at least one year. If hardwood is not

available, tamarack, yellow pine, white pine, Eastern red

cedar, r, and redwood are softwoods that are commonly

burned. They too should be properly dried. The length

of the wood should be the same as that specied for your

particular stove. Avoid using wood that has been dried more

than two years. Often gray in color, this wood burns very

quickly, resulting in short burn time and diminished stove

performance. If you must burn it, mix it in with greener

wood to slow the burn. The length of the wood should be

23” (580 mm).

When burning coal with the combustor removed, we recom-

mend that you use only premium grade anthracite. Three

sizes of coal are commonly burned: pea coal, a very small

size averaging 3/8” to 3/4” (10-20 mm); nut coal, a medium

size of 3/4” to 1¹⁄₂” (20-40 mm); and stove coal, the largest

size at 1¹⁄₂” to 2³⁄₄” (40-70 mm).

NOTE: Coal may be burned in the Sequoia only when the

8” (200mm) ue collar is used, and then only with optional

coal kit #5531 installed.

Both wood and coal should be stored under cover to main-

tain dryness. Even for short-term storage, keep wood and

coal a safe distance from the heater and keep it out of the

areas around heater used for refueling and ash removal.

Use the Air Control Settings

that Work Best for You

No single combination of control settings will t every situ-

ation. Each installation will differ depending on the quality

of the fuel, the amount of heat desired, and how long you

wish the re to burn.

Control settings also depend on your particular installation’s

“draft,” or the force that moves air from the stove up through

the chimney. Draft is affected by such things as the height,

type, and location of the chimney, local geography, nearby

obstructions, and other factors.

Too much draft may cause excessive temperatures in the

stove. On the other hand, too little draft can cause back-

pufng into the room and/or the “plugging” of the chimney

and catalytic burner.

How do you know if your draft is excessively high or low?

Symptoms of too much draft include an uncontrollable burn

or a glowing-red part of the stove or chimney connector.

A sign of inadequate draft is smoke leaking into the room

through the stove or chimney connector joints.

In some newer homes that are well-insulated and weather-

tight, poor draft may result from insufcient air in the

house. In such instances, an open window near the stove

on the windward side of the house will provide the fresh

air needed.

Another option for getting more combustion air to the stove

is to duct air directly from the outside to the stove. In fact,

in some areas provisions for outside combustion air are

required in all new construction.

Your Sequoia is designed to incorporate outside combus-

tion air, and directions for installing an outside air duct may

be found in the Assembly section.

When rst using the stove, keep a record of the results

you achieve from different control settings. You will nd

that specic control settings will give you a xed amount of

heat. It may take a week or two to determine the amount of

heat and the length of burn you should expect from various

control settings.

Dutchwest

Sequoia

2001049

Most installations do not require a large amount of com-

bustion air, especially if adequate draft is available. Do not

for any reason attempt to increase the ring of your

heater by altering the air control adjustment range

outlined in these directions.

Use the following air control settings as a starting point to

help determine the best settings for your installation:

NOTE: To make the settings for these directions as clear

as possible, imagine that the face of a clock is mounted

behind the primary air control lever. Then, follow the direc-

tions to set the lever at the correct “time”. (Fig. 20)

combustor air is closed when rotated fully clockwise.)

Burn Rate Coal-Only Air

Low 1/2 turn

Medium 1¹⁄₂ turns

If your stove is equipped with an optional blower, it is

important to follow these guidelines as well for best re-

sults:

At low-to-medium heat outputs, (a control setting of 6:00

to 7:00) the optional convection blower switch should be

set on the “low” position, never on “high”.

At higher heat outputs, (8:00 or more) the blower can be

set on high if desired.

NOTE: The coal-only air control must always be

closed during a wood re. Likewise, the primary and

combustor air controls must be close when burning

coal.

DO NOT OPERATE THE STOVE WITH THE ASH DOOR

OPEN. THIS CAN CAUSE EXTREME OVERFIRING OF

THE STOVE, WHICH IS DANGEROUS.

The stove’s paint and cement will emit a slight odor

during the rst few res. We suggest that you provide

extra ventilation near the stove by partially opening a

door or window when the odor is present.

How to Build a Wood Fire

and Keep it Going

Make sure your stove is set up correctly for burning

wood.

A Sequoia leaves the factory with the catalytic combustor

installed.

In the United States it is against the law to operate this

wood heater in a manner inconsistent with the operating

instructions in this manual, or if the catalytic combustor is

deactivated or removed.

The grate covers are also installed. These are necessary

for wood burning and should be left in place.

High-Efciency Wood Burning

with Catalytic Combustion

Smoke from a wood re is really escaping energy that

has not been burned to produce the heat. Combustion

temperatures of 1100°F (595°C) are required to burn the

smoke, and a level this high seldom is present in a re set

to burn several hours. As a result, long res in conventional

stoves lose a great deal of potential heat up the chimney

as smoke.

A catalytic combustor captures this heat by lowering the

temperature at which smoke will burn. This makes high

efciency possible even with long, low level res.

Catalytic combustion is activated with two adjustments: by

closing the stove damper, thereby exposing the smoke to

the combustor, and by opening the combustor air control.

The combustor needs extra air during medium and high

burns, and the Sequoia’s combustor air control must be

fully open to supply it. During low burns, the combustor air

control should be open only a 1/2 turn.

temperature. When you rst begin using your Sequoia,

minimize thermal stress by allowing the plates to adjust

gradually during three or four initial break-in res following

Steps 1-3 below.

Starting and Maintaining a Wood Fire

Wood may be loaded into the Sequoia from either the front

or the side. Loading from the front is useful for kindling a

new re or adding an occasional log, but we recommend

side loading as the most convenient way of regularly add-

ing several logs at a time.

When burning wood, your Sequoia may be operated with

the front doors open, for replace-style viewing, as well

as closed. The stove damper must be open and the re-

screen must be in place whenever the door is open for

re viewing.

WARNING: For safety and greatest efciency, operate

your stove only with all doors fully closed. The test

standard when the stove is operated in this mode is

UL1482.

Your stove may be operated as a replace with the

doors opened or removed only when equipped with

an 8” (200mm) ue collar and only with the optional

spark screen placed correctly in the opening to protect

against the possibility of sparks and embers leaving

the stove. The test standard for your stove when it is

1. Open the stove damper, and open the primary air con-

trol fully. Open the combustor air control two turns. The

coal only air control must always be closed during wood

burning.

2. Place crumpled newspaper in the stove. Do NOT use

glossy advertisements or colored paper, as they can

poison the catalyst. Place six or eight pieces of dry

kindling split to a nger-width size on the paper, and

on the kindling lay two or three larger sticks of split dry

wood approximately 1-2” (25-50mm).

DO NOT USE CHEMICALS OR FLUIDS TO START THE

FIRE. DO NOT BURN GARBAGE OR FLAMMABLE

FLUIDS SUCH AS GASOLINE, NAPTHA OR ENGINE

OIL. Also, never use gasoline-type lantern fuel, kerosene,

charcoal lighter uid, or similar liquids to start or “freshen

up” a re in this heater. Keep all such liquids well away

from the heater while it is in use.

3. Light the newspaper and close the door. Within 10-15

minutes the re should be well established and you

may gradually build up the re by adding a few 3-5”

(80-120mm) diameter splits. If this is one of the rst few

“break-in” res, let the re burn brightly, and then let it

die out.

Closing the stove

damper also re-

duces the draft,

so to avoid put-

ting out the fire

or deactivating

the combustor,

close the damper

only when a re is

well established.

When starting a

re, wait until the

re is well estab-

lished and there is an ember bed of at least two inches

before closing the stove damper.

Never kindle a re with colored paper or paper that has

colored ink or a glossy surface, and never burn treated

wood, garbage, solvents, or trash. All of these may poison

the catalyst and prevent it from operating properly. Never

burn cardboard or loose paper except for kindling purposes.

This can cause smoke to spill into the room and effect the

combustor operation. Coal smoke can also poison the

catalyst so that it will not operate properly.

In general, the temperature in the stove and the gases

entering the combustor must be raised to approximately

800°F (430°C) to ensure that catalytic activity is initiated.

During the start-up of a cold stove, a medium-to high-ring

rate must be maintained for about twenty minutes. This

ensures that the stove, catalyst and fuel are all stabilized

at the proper operating temperatures.

Even though it is possible to have gas temperatures reach

several hundred degrees within two to three minutes after

a re is started, the combustor may stop working or the re

may go out if the re is allowed to die down immediately.

Once the combustor starts working, heat generated by

burning the smoke will keep it working.

The best operating range for the combustor is a reading of

1000-1400°F (540-760°C) on a probe thermometer. Temper-

atures over 1700°F (925°C) may damage the combustor.

To determine whether the combustor is operating, check

the probe thermometer in the top of the stove. If it reads

800° (430°C) or higher, it is likely that the combustor is

operating. If temperatures are lower than this, increase the

intensity of the re either by adding fuel or by increasing

the amount of primary air.

Another way to tell if the combustor is working is to ob-

serve the amount of smoke leaving the chimney when the

damper is activated and when it is not. This procedure is

described on Page 25.

Conditioning Your Stove

Cast iron is extremely strong, but it can be broken with a

sharp blow from a hammer or from the thermal shock of

rapid and extreme temperature changes.

The cast plates expand and contract with changes in

If the break-in procedure has been completed, continue

building the re until you have a live ember bed about

2” (50mm) thick.

You will soon nd out that this stove is HOT WHILE IN

OPERATION! KEEP CHILDREN, CLOTHING AND FUR-

NITURE AWAY. CONTACT MAY CAUSE SKIN BURNS.

NOTE: Some chimneys, especially oversized or exterior

chimneys, need to “primed”, or warmed up, before they will

draw sufciently to start a re. To correct this situation, roll

up a couple pieces of newspaper, place them on top of the

kindling and toward the back of the stove, light them and

close the doors. This should heat the chimney enough to

initiate a draft.

Once the draft is established, open the front door and light

the rest of the fuel from the bottom. Do not light the main

bed of fuel until the chimney begins drawing, and repeat

the procedure as often as necessary if the initial attempt

is unsuccessful.

4. After the temperature on the probe thermometer has

reached 450-500°F (232-260°C) (depending on your

individual wood and draft situation), close the stove

damper. This will activate the combustor. To ensure

continued operation of the combustor, let the tempera-

ture approach at least 850°F (454°C) before reducing

the air settings.

5. Close the primary air control to a medium setting, or

about 6:00-7:00 on the imaginary clock face referred to

on Page 18. The re volume will diminish immediately,

but the stove will continue to warm up. Maintain control

of the re using the primary air and combustor air con-

trols, and remember: reduce the setting for a smaller re,

increase the setting for a larger re. Refer back to the

air control settings chart on Page 18 for recommended

settings at different burn rates.

DO NOT OVERFIRE THIS HEATER. Overring may cause

a house re, or can result in permanent damage to the stove

and to the catalytic combustor. If an exterior part of the stove

or the chimney connector glows, you are overring.

Reloading and Reviving a Wood Fire

Open the stove damper and wait at least fteen seconds

for the draft to increase. Open the door slowly and add the

fuel. Split wood will ll the rebox more completely and

reduce the frequency of reloading.

Leave the stove damper open for a short time until the

probe temperature reaches 800°F (430°C), then close it.

Frequently the temperature will drop below 800°F (430°C)

after reloading, particularly if the loading door is open a

long time. Should the temperature drop below this level,

stimulate the re by increasing the primary air supply while

leaving the stove damper open. Reduce the air supply and

close the stove damper when the temperature has reached

800°F (430°C).

NOTE: If the charcoal bed is relatively thick and your fuel

is well-seasoned, it is possible to add fresh fuel (smaller

pieces rst), close the door and damper, and reset the air

control within ve minutes.

Draft is affected by a number of variables, such as outside

temperatures and quality of fuel. Adjusting your operation

in response to these variables may be helpful. To maintain

good draft under adverse conditions, refuel as often as

necessary to keep the bed of the rebox covered with a

‘robust’ layer of hot coals. Run the stove at temperatures

a little above minimum recommended temperatures.

Remove and Store Ash Safely

Wearing protective stove gloves, check the ash pan before

reloading the stove. If the ash level is close to the top, empty

the pan. Before replacing the ash pan, clear away any ash

that has spilled over the sides and back of the pan.

When burning wood, empty the ash drawer regularly,

typically every one to three days. The frequency will vary

depending on how hot you run your stove: the hotter the

re, the more wood you burn, and the faster ash will ac-

cumulate.

Ash may contain hot coals and must be treated with ex-

treme care.

Coal ash will accumulate rather quickly and will require

emptying the ash drawer at least once a day. Empty it

before shaking and reloading to allow the newly-shaken

ash to cool before the next shakedown.

Always Dispose of Ash in a Safe Manner

Ash should be removed frequently and placed outdoors in a

metal container with a tight-tting lid. The closed container

of ash should be placed on a noncombustible oor or on the

g r o u n d ,

well away

persed, it

CAUTION: Never use a vacuum cleaner to remove ash

from the stove; always remove and dispose of the ash

properly.
