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

Environmental Protection Agency’s emission limits for wood heaters sold after July 1, 1990. Under specific 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) flue collar also burns coal. Coal-

burning in the Sequoia is not allowed with the 6” (150mm) flue 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”

(200mm) flue 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”

(150mm) flue collar is not tested to ANSI/UL 737 and should not be used in conjunction with fireplace screen. The Sequoia is not listed for

installation in mobile homes.

Proposition 65 Warning: Fuels used in gas,

woodburning or oil fired appliances, and the products

of combustion 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 INSPECTION

REQUIREMENTS IN YOUR AREA.

Before you begin the installation, review your plans to

confirm that:

• Your stove and chimney connector will be far enough

from combustible materials to meet all clearance

requirements.

• The floor protector is large enough and is constructed

properly to meet all requirements.

• You have obtained all necessary permits from local

authorities.

Your local building official is the final 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

laboratory. 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 installation 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, Fire-

places, 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 official may have a copy of these

regulations.

Important: Failure to follow these installation instruc-

tions may result in a dangerous situation, including a

chimney or house fire. 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

chimney 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 fire department official will be

able either to make the inspection or to direct you to

someone who can.

An inspection of the chimney must confirm that it has a

lining. 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. Open-

ings sealed with pie plates or wallpaper are a hazard

and should be sealed with mortar or refractory cement.

In the event of a chimney fire, flames 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. Ma-

sonry chimneys must be lined, either with code-ap-

proved masonry 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 Tem-

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

WARNING: Do not use double-wall chimney con-

nectors with the Sequoia unless they have been

specifically 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 fire.

DO NOT CONNECT THIS UNIT TO A CHIMNEY

FLUE SERVING ANOTHER APPLIANCE.

Chimney Size

A Sequoia with an 8” (203mm) flue collar is approved

for venting into a masonry chimney with a nominal flue

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

size of 8” (203mm). A Sequoia with a 6” (152mm) flue

collar is approved for venting into a masonry chimney

with a nominal flue size of 8” x 8” (203 x 203mm), and

into a round flue size of 6” (152mm).

Whatever the flue 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 305mm) may experience rapid

cooling of smoke and reduction in draft, especially if

they are located outside the home. These large chim-

neys may need to be insulated or have their flues

relined for proper stove performance.

Accessories to help make the connection between

stainless 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 flue collar to the top of the chimney. The recom-

mended minimum chimney height is 16’ (4.9m).

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 flue. Chimney connectors are used only to make

the connection from the stove to the chimney.

Do not pass the chimney connector through a combus-

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

similar concealed space. If passage through a combus-

tible 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” (203mm) for an 8”

(203mm) flue collare or 6” (152mm) for the 6” (152mm)

flue collar.

Install the chimney connector not less than 18"

(457mm) 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 (20mm per meter) going from the stove toward the

chimney. The recommended maximum length of

horizontal run is 3’ (914mm), and the total length of

chimney connector should be no longer than 8’(2.4m).

In cathedral ceiling installations, extend the prefabri-

cated chimney downward to within 8’ (2.4 meters) of the

Dutchwest Sequoia

2001049

stove. The entire chimney connector should be ex-

posed and accessible 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 flue collar

of the stove,

assemble the

chimney

connector.

Insert the first

crimped end

into the stove’s

flue collar, and

keep each

crimped end

pointing toward

the stove.

Using the

holes in the

flue collar as

guides, drill

1/8” (3mm)

holes in the bottom of the first section of chimney

connector and secure it to the flue collar with three

#10 x 1/2” sheet metal screws.

• Secure each joint between sections of chimney

connector, including telescoping joints, with at least

three sheet metal screws. The predrilled holes in the

top of each section of chimney connector serve as

guides when you drill 1/8” (3mm) holes in the bottom

of the next section.

• Secure the chimney 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 con-

nector 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

manufacturer exactly as you install the chimney. The

manufacturer of the chimney will supply the accesso-

ries 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 chim-

ney and the chimney connector. The top of such

adapters attach directly to the chimney or to the

chimney's ceiling support package, while the bottom of

the adapter is screwed to the chimney connector.

These adapters are designed so the top end will fit

outside the inner wall of the chimney, and the bottom

end will fit inside the first 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 freestand-

ing masonry chimney or a masonry fireplace chimney.

Freestanding Installations

If the chimney connector must pass through a combus-

tible wall to reach the chimney, follow the recommen-

dations in the wall pass-through section that follows.

The opening through the chimney wall to the flue (the

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

cylinder, called the “thimble”, which is securely ce-

mented in place. (Fig. 5) Most chimney breeches

incorporate thimbles, but check to be sure the fit is

snug and the joint between thimble and chimney wall

firmly cemented.

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

is flush with the inner flue wall. Do not extend it into the

actual flue 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

fireplace chimney. The liner of the fireplace chimney

should extend at least to the point at which the chim-

ney 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

necessary combination of mantel, trim, and connec-

tor heat shields to provide the required clearances.

(Fig. 8)

• Double-check connector clearance from the ceiling.

• The fireplace damper must be closed and sealed to

prevent room air from being drawn up the flue,

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 fireplace opening is at least 30”

(762mm), you may install a Sequoia through the

opening using a “positive connection” kit available from

your local dealer. These kits ensure a tight fit between

the stove flue collar and the chimney flue.

Fireplace installations, whether connected to the flue

above or through the fireplace opening, have special

clearance requirements to adjacent trim and the

mantel. You will find the required safe clearances for

Sequoia fireplace installation on Page 10.

Floor protection requirements also apply to fireplace

installation. Be sure to review the floor protection

requirements on Page 8.

Floor Protection

A tremendous amount of heat radiates from the bottom

plate of your Sequoia stove. The floor 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 firebox.

Heat protection is provided through the use of a

Dutchwest Bottom Heat Shield. Spark and ember

protection must be provided by a floor protector

constructed with noncombustible material as specified.

Most installations will require that the bottom heat

shield be attached. Only when the stove is placed on a

Wall Pass-Throughs

Whenever possible, design your installation so the

connector 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 manu-

facturer for any specific requirements.

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

Association (NFPA) has established guidelines for

passing chimney 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 sufficient

distance from the single-wall connector to provide the

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

material used to close up the opening must be noncom-

bustible.

In Canada, the Canadian Standards Association has

established different guidelines. Figure 11 shows one

method, in which all combustible material in the wall is

cut away to provide the required 18” (457mm) clear-

ance for the connector. The resulting space must

remain empty. A flush-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 noncom-

bustible spacers at least 1” (25mm) 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) fireplace. These appliances and their

chimneys are specifically designed as a unit for use as

fireplaces. It may void the listing or be hazardous to

adapt them to any other use.

DO NOT CONNECT THE HEATER TO ANY AIR

DISTRIBUTION DUCT OR SYSTEM.

Three other methods are also approved by the NFPA.

These are:

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

clearance to combustibles.

• Placing a chimney connector pipe inside a ventilated

thimble, which is then separated from combustibles

by 6” of fiberglass 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 combustibles.

Dutchwest Sequoia

2001049

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 floor beneath.

For installation with the heat shield attached, use a

noncombustible floor protector such as 1/4" non-

asbestos mineral board or equivalent, or 24 gauge

sheet metal. The floor 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 floor 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 under the chimney connector and 2” to

either side. Refer to Figure 12 for minimum noncom-

bustible floor protection dimensions.

To meet these requirements, a floor protector must be

at least 48” wide and 42” deep.

In Canada: a noncombustible floor protector is re-

quired under the heater also. The floor protector must

extend 18” (457mm) from the front and left (loading

door) side of the stove, and at least 6” (150mm) from

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

under the chimney connector and 2” to either side.

Refer to Figure 12 for minimum noncombustible floor

protection dimensions.

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

(610mm) long consisting of 1/2” (13mm) 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” (406mm) in front of and 8” (203mm) under

the unit. The floor protector may be covered with a

noncombustible decorative material if desired. Do not

obstruct the space under the heater.

To meet these requirements, a floor protector must be

50” (1270mm) wide and 44” (1118mm) deep.

Due to the side loading door, floor protector require-

ments 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.

Fig. 12 Required floor protection dimensions.

Floor Protection for Fireplace

Do not assume that your fireplace hearth is completely

noncombustible. Many fireplace hearths do not satisfy

the “completely noncombustible” requirement because

the brick or concrete in front of the fireplace 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 fireplace

hearths can be a fire hazard and are considered a

combustible floor. (Fig. 13)

ST730

Fig. 13 Combustible supporting timbers may lie beneath

fireplace hearths; such situations require additional floor

protection.

Wood Framing

For all fireplace installations, follow the floor 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,

sufficient floor protection as described above must be

added in front of the hearth to satisfy the minimum

floor protector requirement from the front of the stove:

16” (406mm) in the United States and 18” (457mm) in

Canada.

insulation board such as Durock

or Wonderboard

, or

common brick “laid on flat,” 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 flow 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)

Fireplace Installations

A fireplace 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 fireplace face, and between the top of

the stove and the mantel.

Ventilated, noncombustible shields installed on

noncombustible spacers 1” (25mm) away from the

combustible surface may be used to reduce

clearances. A mantel shield for the Sequoia must be at

least 48” (1220mm) long, centered over the stove. Side

trim shields must extend the full length of the trim.

In addition, a fireplace installation must observe the

floor protection guidelines discussed previously.

The charts and illustrations that follow depict all the

clearances required for the various installation

configurations of the Sequoia.

Hearth rugs do not satisfy the requirement for floor

protection as they are not fire proof.

Fireplace installations also have special clearance

requirements to the side walls, side decorative trim and

fireplace mantel. Refer to the information on fireplace

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, floors, the

ceiling, and any other fixed combustible surface. Keep

furnishings and other combustible materials away from

the stove as well. In general, a distance of 48" (1220

mm) must be maintained between the stove and

moveable combustible items such as drying clothes,

furniture, newspapers, firewood, etc. Keeping those

clearance areas empty assures that nearby surfaces

and objects will not overheat.

Safe Ways to Reduce Clearances

Your stove has specific 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

combination of basic variables:

• When the stove

has no

listed heat shield

• When the stove

has

a listed heat shield

• 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 configurations of Sequoia.

Wall Shields

One way to reduce clearances is with a wall shield

constructed of 24 gauge or heavier sheet metal, or of

another noncombustible material such as 1/2" (13 mm)

Unpack the Parts

Remove all loose parts from the firebox 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

damper

• 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 fit 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 sur-

rounding 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 finger-tight

with bolt. Repeat this step for each of the four legs.

Assembly

*Bottom heat shields are standard only on stoves sold

in Canada.

Next, fasten the bottom heat shield to the brackets,

adjusting the legs as needed to make the shield fit.

Tighten the shield securely, then use a wrench to

tighten the leg bolts firmly. 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 fingers 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 in-

stalled. 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 combus-

tion, 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.

• 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 fire 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 fires. It

is always closed when burning coal. It opens when

moved clockwise and closes when moved counter-

clockwise.

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 fires. 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 fire; and closed for greatest

efficiency and heat. Using the multipurpose door

handle, rotate the damper knob counterclockwise to

open the damper and clockwise to close it.

Operation

The stove damper must be open when starting a fire,

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.

Load Doors

The Side Loading Door allows the easiest loading of

wood logs.

When the Sequoia is equipped with an 8” (200mm) flue

collar, the Front Door may be utilized as well for

loading coal or for adding an occasional log to wood

fires. Also, the front door may be opened wide and an

optional spark screen, Part No. 0135, placed in the

opening for safe, fireplace-style viewing when burning

wood. The front door must remain closed at all times

when the 6” (150mm) flue collar is used.

With either flue size, the fire may still be viewed

through the large ceramic viewing window when the

front door is closed.

A Probe Thermometer Port Provides

Access to Internal Temperatures

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 efficiencies and low emissions are possible when

burning air-dried, seasoned woods as compared to

softwoods 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 outside under cover for at least one year. If

hardwood is not available, tamarack, yellow pine, white

pine, Eastern red cedar, fir, and redwood are softwoods

that are commonly burned. They too should be prop-

erly dried. The length of the wood should be the same

as that specified 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” (580mm).

When burning coal with the combustor removed, we

recommend that you use only premium grade anthra-

cite. Three sizes of coal are commonly burned: pea

coal, a very small size averaging 3/8” to 3/4” (10-

20mm); nut coal, a medium size of 3/4” to 1¹⁄₂” (20-

40mm); and stove coal, the largest size at 1¹⁄₂” to 2³⁄₄”

(40-70mm).

NOTE: Coal may be burned in the Sequoia only when

the 8” (200mm) flue collar is used, and then only with

optional coal kit #5531 installed.

Both wood and coal should be stored under cover to

maintain 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 fit every

situation. Each installation will differ depending on the

quality of the fuel, the amount of heat desired, and how

long you wish the fire 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

backpuffing 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 uncontrol-

lable 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 insufficient 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

combustion air, and directions for installing an outside

air duct may be found in the Assembly section.

When first using the stove, keep a record of the results

you achieve from different control settings. You will find

that specific control settings will give you a fixed

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.

Most installations do not require a large amount of

combustion air, especially if adequate draft is available.

Do not for any reason attempt to increase the firing

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 directions to set the lever at the correct

“time”. (Fig. 20)

while the combustor air is closed when rotated fully

Burn Rate Coal-Only Air

Low 1/2 turn

Medium 1¹⁄₂ turns

High Fully open

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

important to follow these guidelines as well for best

results:

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 fire. 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 DANGER-

OUS.

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

during the first few fires. We suggest that you

provide extra ventilation near the stove by partially

opening a door or window when the odor is

present.

ST756

Fig. 20 The Sequoia’s primary air supply is closed at the 5

o’clock position, and fully open at 8 o’clock or more.

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 operat-

ing instructions in this manual, or if the catalytic com-

bustor is deactivated or removed.

The grate covers are also installed. These are neces-

sary for wood burning and should be left in place.

High-Efficiency Wood Burning

with Catalytic Combustion

Smoke from a wood fire 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

fire set to burn several hours. As a result, long fires 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

efficiency possible even with long, low level fires.

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.

Closing the stove damper also reduces the draft, so to

avoid putting out the fire or deactivating the combustor,

close the damper only when a fire is well established.

When starting a fire, wait until the fire is well estab-

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

before closing the stove damper.
