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

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
6
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.

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. 6)

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.

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.

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.

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)

2 Shielding for a top exit stove must include a shield insert to protect the area behind the flue collar.
3 Chimney connector heat shields must extend to within 1” (25mm) or less of the ceiling heat shield for installations
venting straight up to a factory-built chimney. Top exit installations using an elbow to vent to rear chimney connector
must be shielded over entire vertical length.

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
clockwise.)
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.

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.
