1. Maximum burn times and heat outputs are based on laboratory testing using full loads of seasoned hardwoods, and may vary in individual use
depending on how the stove is operated, type and moisture content of fuels, and other factors. Maximum burn times are achieved under different
operating conditions than are maximum heat outputs.

2. These values are based on operation in building code-conforming homes under typical Winter climate conditions in the northeastern U.S. If your
home is of nonstandard construction (e.g. unusually well-insulated, not insulated, built underground, or if you live in a more severe or more temper­ate climate), these figures may not apply. Since so many variables affect performance, consult your Dutchwest Authorized Dealer to determine
realistic expectations for your home.

Installation

SAFETY NOTICE: IF YOUR DUTCHWEST CON­VECTION 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 material 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 ap

­proving your installation as safe and for determining
that it meets local and state codes.

Clearance and installation information is printed on the
metal label attached to the rear of the stove. 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.

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.

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 chim
ney 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.

Chimney Types

Your Dutchwest Convection Heater must be connected
to 1) a chimney complying with the requirements for
Type HT chimneys in the standard for Chimneys, Fac­tory-Built, Residential Type and Building Heating Appli­ance, UL 103, or 2) a code-approved masonry chimney
with a flue liner.

Whatever kind you use, the chimney and chimney con­nector must be in good condition and kept clean.

Prefabricated Chimneys

A prefabricated metal chimney must be one tested and
listed for use with solid-fuel burning appliances.

A horizontal connector run should be inclined 1/4” per
foot (20 mm per meter) from the stove toward the
chimney. The recommended maximum length of a hori­zontal run is 3 feet (1m) and the total length of chimney
connector should be no longer than 8 feet (2.5m).

Chimney Height

For proper draft and good performance, the chimney
should extend at least 16’ (5 m) above the flue collar of
the stove.

The chimney must also extend at least 3’ (914 mm)
above the highest point where it passes through a roof,
and at least 2’ (610 mm) higher than any portion of a
building within 10’ (3 m). (Fig. 2)

DO NOT CONNECT THIS UNIT TO A CHIMNEY
FLUE SERVING ANOTHER APPLIANCE.

AC246

Fig. 3 The 2/3/10 rule for chimneys.

Chimney Size

The Model 2478 heater should be vented into a ma­sonry chimney with a square flue with nominal flue size
of 8” x 8” (203 x 203 mm), or a round flue with nominal
flue size of 6” (152 mm).

Chimney liners larger than 8” x 12” (203 x 305 mm)
may promote 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 the stove are avail­able through your local dealer.

Guidelines for Installing

the Chimney Connector

The chimney connector is the single-wall pipe, or listed
and approved double-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, floor, or ceiling, through an attic or roof space,
or through a closet or similar concealed space. If pas­sage through a combustible wall is unavoidable, follow
the recommendations in the following section on Wall
Pass-Throughs. Keep the passage as short and direct
as possible, with no more than two 90 degree turns.

Two Types of Connector

You may use either a single-wall steel connector of the
size and gauge described below, or a listed and ap­proved double-wall connector.

Single-Wall Connector

The single-wall chimney connector should be made of
24 gauge or heavier steel, and must have a minimum
internal diameter of 6” (150 mm) for model 2478.

Install single-wall chimney connector not less than 18”
(450 mm) from the ceiling.

In cathedral ceiling installations, extend the prefabri­cated chimney downward to within 8 feet (2.5 meters)
of the 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.

Double-Wall Connector

Information on assembling and installing double-wall
connectors is provided by the manufacturer of the
double-wall pipe. Follow the manufacturer’s installation
instructions exactly. Most manufacturers of prefabri­cated double-wall insulated chimneys also offer double­wall connector pipes. Using a chimney and connector
pipe from the same manufacturer helps simplify the
assembly and installation.

NOTE: For installations using double-wall connec­tors, minimum clearances must conform to listed
clearances in the Stove and Chimney Connector
Clearance Charts on Page 12 and 13 of this manual.

Assembling Single-Wall

Chimney Connector

SAFETY NOTE: Always wear gloves and safety
goggles when drilling, cutting or joining sections of
chimney connector.

For double-wall connectors, follow the manufacturer’s
instructions exactly. For single-wall connectors, follow
the instructions below.

1. Insert the crimped end of the first section into the
stove’s flue collar, and keep each crimped end pointing
toward the stove (Fig.5). Using the holes in the flue col­lar as guides, drill 1/8” (3 mm) 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

2. Secure each joint between sections of chimney con-

nector, including telescoping joints, with at least three
sheet metal screws.

3. Secure the chimney connector to the chimney. In­structions for various installations follow below.

4. Confirm that the installed stove and chimney con-
nector are correct distances from nearby combustible
material. See the clearance charts on pages 12 and 13.

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 adaptors are available from your local dealer
to make the connection between the prefabricated
chimney and the chimney connector. (Fig. 6) The top
of such adaptors attach directly to the chimney or to the
chimney’s ceiling support package, while the bottom of
the adaptor is screwed to the chimney connector.

These adaptors 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.

Dutchwest Non-Catalytic Convection Heater

Securing the Connector

to a Masonry Chimney

The Dutchwest Convection heater 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. 7) 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. Thimble
sleeves should be available from your local dealer.

To install a thimble sleeve, slide it into the breech until
it is flush with the inner flue wall. Don’t 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.

Dutchwest Non-Catalytic Convection Heater

Fireplace Installations -

Through the Fireplace

The Convection heater may be installed either without
legs* as a fireplace insert, or with standard legs at­tached - depending on the safety regulations that apply
to your situation, the height of the fireplace opening and
your own preference. For either situation, the chimney
connector/positive connection kit extends back from the
stove, enters the fireplace cavity, and turns upward. It
then passes through the fireplace damper opening and
smoke chamber and connects to the chimney flue.

In such installations, a “positive connection” must be
made to the chimney flue with a special kit available
from your local dealer. Also, special clearance and floor
protection provisions must be observed. These provi­sions are discussed in the Clearance and Floor Protec­tion sections respectively.

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.

All combustible material in the wall is cut away a suffi­cient distance from the single-wall connector to provide
the required 12” (305 mm) clearance for the connector.
Any material used to close up the opening must be non­combustible.

The following wall pass-through methods may be ap­proved in your area:

• Use a section of listed factory-built chimney with a
nine-inch clearance to combustibles.

• Place a chimney connector pipe inside a ventilated
thimble, which is then separated from combustibles
by 6” (152 mm) of fiberglass insulating material.

• If the stove is installed without legs, we recommend
the use of noncombustible tiles or pavers as shims to
allow air flow into the convection air inlets under the
stove. Make sure not to block air slots instove bottom
with shims or remove fan cover.

• Place a chimney connector pipe inside a section of
listed solid-insulated, factory-built chimney, with an
inside diameter 2” (51 mm) larger than the chimney
connector and having 1” (25 mm) or more of insula­tion and maintaining a minimum 2 inch air space
between the outer wall of the chimney and combus­tibles.

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” (450 mm) clear­ance for the connector. The resulting space must
remain empty.

side only. If covers must be used on both sides, each
cover must be mounted on non-combustible spacers
at least 1” (25 mm) clear of the wall. Your Dutchwest
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 Dutchwest stove into a factory­built (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 for any other use.

Floor Protection

A tremendous amount of heat radiates from the bottom
plate of your Dutchwest 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 by the CFM Corporation
Bottom Heat Shield. Spark, ember and thermal protec­tion must be provided by a floor protector constructed
with noncombustible material as specified.

In the US and Canada most installations will require
that the bottom heat shield must be attached. Only
when the stove is placed on a completely noncombusti­ble surface such as unpainted concrete over earth may
it 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 an
approved 5/8” (16mm) noncombustible hearth pad with
K = 0.84 BTU/in ft2 hr °F or an equivalent material with
an R-value of at least 0.744. (Refer to “How to Deter­mine if Alternate Floor Protection Materials are Accept­able” section)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)

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 8” (203mm) from the right side
and rear. (Fig. 12)

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.

How to Determine if Alternate Floor Protection Ma­terials are Acceptable

All floor protection must be noncombustible (i.e. met
als, brick, stone, mineral fiber boards, etc.). Any organic
materials (i.e. plastics, wood paper products, etc.) are
combustible and must not be used. The floor protection
specified includes some form of thermal designation
such as R-value (thermal resistance) or k-factor (ther­mal conductivity).

iv. r-factor is given with a required thickness (T) in

inches: R = r x T

2. Determine the R-value of the proposed alternate

floor protector:
i. Use the formula in Step 1 to convert values not

expressed as R.

ii. For multiple layers, add R-values of each layer to

determine overall R-value.

3. If the overall R-value of the system is greater than

the R-value of the specified floor protector, the alter
nate is acceptable.

EXAMPLE: The specified floor protector should be 5/8­inch thick material with k-factor of 0.84. The proposed
alternate is 4” brick with an r-factor of 0.2 over 1/8”
mineral board with a k-factor of 0.29

Fireplace Installations

To install the heater without legs as a fireplace insert,
the floor must be completely noncombustible, such as
an unpainted concrete floor over earth.

Many fireplaces do not satisfy the “completely non

­combustible” requirement because the brick or con­crete hearth in front of the fireplace opening usually is
supported by heavy wooden framing as in Figure 13.
Because heat passes readily through brick or concrete,
it can easily pass through to the wood. As a result, such
fireplace hearths are considered a combustible floor.
You may not install a heater on a combustible hearth
without legs. Standard leg installations must include the
bottom heat shield. The floor protector must also meet
standard requirements for freestanding installations.

Floor Protection for Fireplace

Installations with Standard Legs

-

Fireplace installations with the standard legs and the
bottom heat shield must have a floor protector of the
same construction as that specified for freestanding
installations: use an approved 5/8” (16mm) noncom­bustible hearth pad with K = 0.84 BTU/in ft2 hr °F or an
equivalent material with an R-value of at least 0.744
(that may be covered with a decorative noncombustible
material if you desire). (Refer to “How to Determine if
Alternate Floor Protection Materials are Acceptable”
section) The floor protector must extend at least 16”
(406 mm) [18” / 457 mm in Canada] from the front of
the stove and from the left (loading door) side, and at
least 8” (203 mm) from the right side and rear. It must
also provide protection beneath any horizontal runs of
the chimney connector, including 2” to either side.

Many raised hearths will extend less than the required
distance from the front of the heater when it is installed.
In such cases, sufficient floor protection, as described
above, must be added to extend the hearth 16” (406
mm) [18” (457 mm) in Canada].

Hearth rugs do not satisfy the requirements for floor
protection.

Fireplace insert installations also have specific clear

­ance requirements to the side walls, side decorative
trim, and fireplace mantel. This information is found in
“Fireplace Installation Clearances” in this section.

REMINDER- FIREPLACE INSERT INSTALLATIONS
WITHOUT LEGS ARE PERMISSIBLE ONLY IF THE
HEARTH IS COMPLETELY NONCOMBUSTIBLE,
SUCH AS UNPAINTED CONCRETE OVER EARTH.

The Dutchwest Model 2478 has a reversible flue collar
to allow for either top exit or rear exit installations.

You may install your Dutchwest Model 2478 in an exist­ing fireplace as a fireplace insert with no legs, or with
the standard legs attached.
