B. Design and Installation Considerations
NOTICE: Checkbuildingcodespriortoinstallation.
• Installation MUST comply with local, regional, state and
national codes and regulations.
• Consult insurance carrier, local building inspector, re
ofcials or authorities having jurisdiction over restrictions,
installation inspection and permits.
1. Selecting Fireplace Locations
This replace 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 replace 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 replace 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 re.
• 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 replace location relative to oor and ceiling
and attic joists.
• Take into consideration the termination requirements in
Sections 5 and 6.
Marginal Location:
• Below peak
Location NOT recommended:
• Not the highest point of the roof
• Wind loading possible
Multi-level Roofs
Windward
Leeward
Recommended Location:
• Above peak
Recommended:
• Insulated exterior chase
in cooler climates
Recommended Location:
• Above peak
• Inside heated space
Location NOT recommended:
• Too close to tree
• Below adjacent structure
• Lower roof line
• Avoid outside wall
Marginal Location:
• Wind loading possible
Not recommended in lower level due
to high negative pressure concerns
that effect draft
Figure 2.3 Recommended Chimney Locations
• Install the outside air kit with the intake facing prevailing
winds during the heating season.
• Ensure adequate outdoor air for all combustion
appliances and exhaust equipment.
• Ensure furnace and air conditioning return vents are not
located in the immediate vicinity of the replace.
• Avoid installing the replace near doors, walkways or
small isolated spaces.
• Recessed lighting should be a “sealed can” design.
• Attic hatches weather stripped or sealed.
• Attic mounted duct work and air handler joints and seams
taped or sealed.

C. Construct the Chase
A chase is a vertical boxlike structure built to enclose the
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 restops/
attic shields at each oor of the chase or every 10 ft (3048
mm) of clear space to control spread of re.
Walls, ceiling, base plate and cantilever oor at the rst
level of the chase should be insulated (see Figure 3.4.)
Vapor and air inltration 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 ber glass
insulation.

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 restop spacer and attic insulation
shield should be installed in an insulated false ceiling
at the 8 ft. (2438 mm) level above the replace
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 replace.
Three examples of chase applications are shown in Fig-
ure 3.5.
WARNING! You must install false ceilings and ceil-
ing restops at each oor of the chase or every 10 ft
(3.05 m) to control spread of re.
WARNING! Risk of Fire! DO NOT sealareabetweenre
stop opening and chimney pipe except where they enter
theatticorleavethewarmairenvelopeofthehome(use

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rmly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replaceorchimney.
• Failuretopreventcontactbetweeninsulationorother
materialsandchimneysystemmaycauseoverheating
andre.

Figure 3.10 Outside Air Inlet Locations
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 inlet hood 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
vertically. In such an installation, a 3 ft (914 mm) height
difference must be maintained from the top of the upper-
most chimney section to the outside air inlet hood.
Refer to Figures 3.10 and 3.11 when placing the outside
air inlet hood.
The outside air kit is installed on the right hand side of the
replace. See Figure 3.12 for handle location/operation.
• Cut a 6-1/2 in. (165 mm) hole in outside wall to
accommodate air piping.
• Use 6 in. (152 mm) metal ex or rigid piping (not supplied)
to directly connect outside air to fireplace intake.
Insulating the pipe isn’t required but will help prevent
frost condensation.
• Use the supplied outside air inlet hood.
• Seal between the wall and the pipe with silicone to
prevent moisture penetration and air leaks.
• Seal between the outside air inlet hood and the house
with silicone to prevent air inltration.
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,oororceilingcavity,or
enclosed spaces such as an attic or garage.
• DO NOT place outside air inlet hood close to exhaust
ventsorchimneys.Fumesorodorcouldbedrawninto
theroomthroughthereplace.
• Locateoutsideairinlethoodtopreventblockagefrom

The Heat-Zone accessory kit conveys warm air from the
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 replace. Installation of this
kit MUST be performed by a qualied 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
must be installed only as specied. If you modify it or any
of its components you will void the warranty and you may
possibly cause a re hazard. Installation must be done
according to applicable local, state, provincial and/or
national codes.
