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. Coal­burning 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.

Installation
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, 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 official 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 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. 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 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. Ma­sonry chimneys must be lined, either with code-ap­proved 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-103­1985 (2100°F.) for the United States, and High Tem­perature (650°C) Standard ULC S-629 for Canada.
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 chim­neys 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 recom­mended 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 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.
WARNING: Do not use double-wall chimney con­nectors 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.
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 prefabri­cated chimney downward to within 8’ (2.4 meters) of the
2001049

Dutchwest Sequoia
stove. The entire chimney connector should be ex­posed 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.
Toward Stove
Flue Gas Direction
ST242
Fig. 5 Crimped sections always point toward the stove so that any liquid condensation will not leak out.
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 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 manufacturer 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 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 freestand­ing masonry chimney or a masonry fireplace 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 flue (the “breech”) must be lined with either a ceramic or metal cylinder, called the “thimble”, which is securely ce­mented 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.

ST243
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 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 necessary combination of mantel, trim, and connec­tor 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.

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 manu­facturer for any specific requirements.
Accessories are available for use as wall pass­throughs. 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 noncom­bustible.
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) clear­ance 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 noncom­bustible 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.

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.

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
8
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" non­asbestos 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 noncom­bustible 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 re­quired 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 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 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)
Wood Framing
Fig. 13 Combustible supporting timbers may lie beneath fireplace hearths; such situations require additional floor protection.
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.

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 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.

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)

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
When the stove
When the wall
When the wall
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.

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.
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)
