1. Selecting Fireplace Locations
This fireplace may be used as a room divider, installed
along a wall, across a corner or used in an exterior chase.
See Figure 2.2.
Locating the fireplace in a basement, near frequently
opened doors, central heat outlets or returns, or other
locations of considerable air movement can affect the
performance.
Outside air must be used for combustion. The C40 comes
equipped with an outside air inlet to feed combustion air
from outside the home, along with an outside air termina-
tion cap; the rigid metal duct is required but not supplied.
Consideration should be given to these factors before
deciding on a location.

2. Locating Fireplace & Chimney
Location of the fireplace and chimney will affect perfor-
mance.
• Install within the warm airspace enclosed by the building
envelope. This helps to produce more draft, especially
during lighting and die-down of the fire.
• Penetrate the highest part of the roof. This minimizes
the effects of wind loading.
• Locate termination cap away from trees, adjacent
structures, uneven roof lines and other obstructions.
• Minimize the use of chimney offsets.
• Consider the fireplace location relative to floor and ceiling
and attic joists.
• Take into consideration the termination requirements in
Sections 5 and 6.

C. Construct the Chase
A chase is a vertical boxlike structure built to enclose the
fi replace and/or its vent system. Vertical chimneys that
run on the outside of a building must be installed inside a
chase.
In cold climates, Hearth & Home Technologies recom-
mends that the chase be well insulated using batt type
insulation between the joists.
Construction of the chase may vary with the type of build-
ing. These instructions are not substitutes for the require-
ments of local building codes. Local building codes MUST
be checked.
Chases should be constructed in the manner of all outside
walls of the home to prevent cold air drafting problems.
The chase should not break the outside building envelope
in any manner. All outer walls need to be insulated.
Building codes require false ceiling and ceiling fi restops/
attic shields at each fl oor of the chase or every 10 ft (3048
mm) of clear space to control spread of fire.
Walls, ceiling, base plate and cantilever floor at the first
level of the chase should be insulated (see Figure 3.4.)
Vapor and air infiltration barriers should be installed in the
chase as per regional codes for the rest of the home. Ad-
ditionally, Hearth & Home Technologies recommends that
the inside surfaces be drywalled and taped (or the use of
an equivalent method) for maximum air tightness.
Holes and other openings should be caulked with high
temperature caulk or stuffed with unfaced fiber glass
insulation.

Figure 3.5 Chase Constructions
1. Fireplace and chimney enclosed in an exterior chase.
2. Chimney offset through exterior wall and enclosed in chase.
3. Chase constructed on roof.
• The chase is constructed using framing materials much
the same as the walls in your home. A variety of siding
materials may be used including brick, stone, veneer
brick, or standard siding materials.
• In constructing the chase, several factors must be
considered:
- Maintain a 2 in. (51 mm) air space around the
chimney.
- The chase top must be constructed of non-
combustible material.
- In cold climates, a firestop spacer and attic insulation
shield should be installed in an insulated false ceiling
at the 8 ft. (2438 mm) level above the fireplace
assembly. This reduces heat loss through the chase.
- In cold climates, the walls of the chase should be
insulated to the level of the false ceiling as shown in
Figure 3.4. This will help reduce heat loss from the
home around the fireplace.
Three examples of chase applications are shown in Fig-
ure 3.5.
WARNING! You must install false ceilings and ceil-
ing firestops at each floor of the chase or every 10 ft
(3.05 m) to control spread of fire.
WARNING! Risk of Fire! DO NOT seal area between fire
stop opening and chimney pipe except where they enter
the attic or leave the warm air envelope of the home (use
600° F sealant).
WARNING! Risk of Fire! You must maintain a minimum
2 in. (51 mm) air space clearance to insulation and other
materials surrounding the chimney system.
• Insulation and other materials must be firmly secured to
prevent accidental contact with chimney system.
• The chase must be properly blocked to prevent blown
insulation or other combustibles from entering and
making contact with fireplace or chimney.
• Failure to prevent contact between insulation or other
materials and chimney system may cause overheating
and fire.

Heatilator • C40 Constitution • 480-2340 Installation Manual • Rev B 01-29-13

D. Frame the Fireplace
NOTICE: Hearth extension design must be determined
before installation of fireplace.
If the fireplace is placed on the fl oor the maximum height
of a fi nished raised hearth is 5-3/4”, if you want a higher
raised hearth the fireplace must be placed on a platform.
NOTICE: Wiring for fans must be done before framed
enclosure is completed. If using a Heat Zone Kit, it
also must be installed before enclosure is complete.
The C40 Fireplace will fit a framed opening height of
46-1/4 in. (1174 mm) tall and 42-1/4 in. (1073 mm) wide.
WARNING! Risk of Fire! You must comply with all
minimum air space clearances to combustibles. DO NOT
pack required air spaces with insulation or other materi-
als.
WARNING! Risk of Fire! Comply with all minimum clear-
ances specified.
• A minimum 1 in. (25 mm) air clearance must be
maintained at the back and 1 in. (25 mm) to the sides
of the fireplace assembly.
• Chimney sections at any level require a 2 in. (51 mm)
minimum air space clearance between the framing and
chimney section.
Figure 3.3 shows a typical framing (using 2 x 4 lumber)
of the fireplace, assuming combustible materials are
used. All required clearances to combustibles around the
fi replace must be adhered to. See Figure 3.2. Any framing
across the top of the fireplace must be above the level of
the top standoffs. (No recess above standoffs.)
The fi nished cavity depth must be no less than 24 in.
(610 mm) from the fi nished backwall to the outside of front
wall framing. Framing must extend straight up all the way
to the ceiling.
CAUTION! Risk of Cuts/Abrasions. Wear protective gloves
and safety glasses during installation. Sheet metal edges
are sharp.
WARNING! Risk of Fire! Prevent contact with sagging,
loose insulation.
•DO NOT install against vapor barriers or exposed
insulation.
• Secure insulation and vapor barriers.
• Provide minimum air space clearances at the sides and
back of the fireplace assembly as outlined in Section 3.
E. Secure and Level the Fireplace
This fireplace may be placed on either a combustible or
noncombustible continuous flat surface. Follow the in-
structions for framing in Section 3. Slide the fireplace into
position. Be sure to provide the minimum 1 in. air clear-
ance at the sides and 1 in. at the back of the fireplace.
The fireplace should be positioned so the face of the non-
combustible material on the fireplace will be flush with the
face of the drywall on the walls. See Figure 3.6.
Level the fireplace and shim as necessary.
These surfaces
must be even!

H. Outside Air Kit
An outside air kit must be used for combustion. Hearth &
Home Technologies recommends you utilize the shortest
duct run to optimize the performance of the outside air kit.
The outside air kit inlet should be positioned in a manner
that will not allow snow, leaves, etc. to block the inlet. In
some installations the air duct may need to be run verti-
cally. In such an installation, a 3 ft (914 mm) height differ-
ence must be maintained from the top of the uppermost
chimney section to the outside combustion air inlet.
Refer to Figures 3.10 and 3.11 when placing the outside
air inlet.
The outside air kit is installed on the right hand side of the
fi replace. See Figure 3.12 for handle location/operation.
• Cut a 6 in. (152 mm) hole in outside wall to accommodate
air piping.
• Use 6 in. (152 mm) metal fl ex or rigid piping (not supplied)
to directly connect outside air to fi replace intake. Insulate
the pipe to prevent frost condensation.
• Use the supplied termination cap.
• Seal between the wall and the pipe with silicone to
prevent moisture penetration and air leaks.
• Seal between the termination cap and the house with
silicone to prevent air infiltration.
CAUTION! Risk of Cuts/Abrasions. Wear protective
gloves and safety glasses during installation. Sheet metal
edges are sharp.
CAUTION! Risk of Fire or Asphyxiation! DO NOT draw
outside combustion air from wall, floor or ceiling cavity, or
enclosed spaces such as an attic or garage.
•DO NOT place outside air hood close to exhaust vents or
chimneys. Fumes or odor could be drawn into the room
through the fireplace.
• Locate outside air inlet to prevent blockage from leaves,
snow/ice, or other debris. Blockages could cause
combustion air starvation.
Attic insulation shield
must be used to keep
insulation away from
chimney.

I. Heat Zone Kit (Optional)
The Heat-Zone accessory kit conveys warm air from the
fi replace through air duct(s) to remote locations in the
same room or other rooms of the building. You may install
1 or 2 Heat-Zone kits on the fireplace. Installation of this
kit MUST be performed by a qualified service technician.
If any parts are missing or damaged, contact your local
dealer before starting installation. DO NOT install a dam-
aged kit.
This kit is tested and safe when installed in accordance
with this installation manual. It is your responsibility to
read all instructions before starting installation and to fol-
low these instructions carefully during installations.
The Heat-Zone® Wood kit is carefully engineered and
