cal building officials about restrictions and installation inspection requirements in your

area.

Dutchwest Sequoia

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

ronmental Protection Agency’s emission limits for wood heaters sold after July 1, 1990. Under 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”

hearth, and we show it in all our cast iron stoves and fireplaces.

As you become acquainted with your new stove or fireplace, you will find that its visual appearance is matched by its

functionality, due to cast iron’s unique ability to absorb and radiate heat.

Also, Dutchwest products are among the cleanest-burning wood stoves and fireplaces available today. And as an

owner of a Dutchwest stove or fireplace, you are making a strong statement for pollution-free energy. But clean burn-

ing depends on both the manufacturer and the operator. Please read this manual carefully to understand how to oper-

ate your stove or fireplace properly.

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

Chimney Connector Guidelines

The chimney connector is the single-wall pipe that con-

nects 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

(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 hori-

zontal run is 3’ (914mm), and the total length of chim-

ney 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 stove. The entire chimney connector should be

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 acces-

adapters attach directly to the chimney or to the chim-

ney’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.

If the height of your fireplace opening is at least 30”

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

ing 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.

Heat protection is provided through the use of a

Dutchwest Bottom Heat Shield. Spark and ember pro-

Whenever possible, design your installation so the con-

nector does not pass through a combustible wall. If you

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

tested and listed for use as a wall pass-through.

In the United States, the national Fire Protection As-

sociation (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

main 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 de-

tails 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 with the heat shield attached, use a non-

combustible 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:

open the damper and clockwise to close it.

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.

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.

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

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

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

long you wish the fire to burn.

Control settings also depend on your particular instal-

lation’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.

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 com-

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

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.
