2. Locating Fireplace & Chimney
Location of the replace and chimney will aect 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.
• Installing the replace in a basement is not recommended.
• Penetrate the highest part of the roof. This minimizes
the eects of wind loading.
• Locate termination cap away from trees, adjacent
structures, uneven roof lines and other obstructions.
• Minimize the use of chimney osets.
• Consider the replace location relative to oor and ceiling
and attic joists.
• Take into consideration the termination requirements in
Sections 4 and 5.
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 basement 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 in-
sulation 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 inltration 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 tem-
perature caulk or stued with unfaced ber glass insulation.

Figure 3.5 Chase Constructions
1. Fireplace and chimney enclosed in an exterior chase.
2. Chimney oset 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 sealareabetweenre
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.
• Insulationandothermaterialsmustbermlysecuredto
prevent accidental contact with chimney system.
• The chase must be properly blocked to prevent blown
insulation or other combustibles from entering and
makingcontactwithreplaceorchimney.
• Failure to prevent contact between insulation or other
materials and chimney system may cause overheating
andre.

als.
WARNING! Risk of Fire! Comply with all minimum clear-
ancesspecied.
• A minimum 1-1/2 in. (38 mm) air clearance must be
maintained at the back and 1-1/2 in. (38 mm) to the
sidesofthereplaceassembly.
• Chimney sections at any level require a 2 in. (51 mm)
minimum air space clearance between the framing and
chimney section.
Figure 3.11 shows a typical framing (using 2 x 4 lumber)
of the replace, assuming combustible materials are
used. All required clearances to combustibles around the
replace must be adhered to. See Figure 3.2. Any framing
across the top of the replace must be above the level of
the top standos.
The
nished cavity depth must be no less than 30-1/2 in.
(775 mm) from the nished backwall to the outside of front
wall framing.
DO NOT install header until the replace is in position.
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
backofthereplaceassembly.
F. Secure and Level the Fireplace
This replace may be placed on either a combustible
or noncombustible continuous at surface. Follow the
instructions for framing in Section 3. Slide the replace
into position. Be sure to provide the minimum 1-1/2 in.
air clearance at the sides and 1-1/2 in. at the back of the
replace.
The replace should be positioned so the face of the non-
combustible material on the replace will be ush with the
face of the drywall on the walls.
Level the replace and shim as necessary.

NOTE: Before framing up the chase, consider where
and how the chimney will run. If there are obstacles
that might be in the way, it may be necessary to make
the chase larger than shown to allow for osets to be
used. Refer to oset chart on page 17 if needed.

• Freestanding Installations (see Figure 3.14 and 3.15)
When installing this replace as a freestanding replace
in your yard, it must be enclosed to prevent impact
damage to the fireplace. Freestanding applications
allow for a reduction in the minimum vent run. Non-
combustible framing and an extended smoke shield are
required. See Table 3.1 and Figure 3.14.
• Porch and Patio Installations
The replace will not perform as an exterior wall. Hearth
& Home Technologies recommends that the replace
chase be constructed outside the structure’s weather
envelope. Where the platform meets the wall, use
a ashing detail similar to that required for attached
decks. Chase platforms, including heaths should slope
away from the structure at 1/8 in. to 1/4 in. per foot. The
replace can be shimmed level.
When Installed on Surfaces Where Water May Collect
or Cause Damage:
Hearth & Home Technologies recommends that a
drainage pan be placed under the unit (sold separately).

H. Outside Air Kit
Two outside air kits must be used for combustion. Hearth
& Home Technologies recommends you utilize the short-
est duct runs to optimize the performance of the outside
air kits and install a P-trap. See Figure 3.16. The outside
air inlet hoods should be positioned in a manner that will
not allow snow, leaves, etc. to block the inlets. In some
installations the air duct may need to be run vertically.
In such an installation, a 3 ft (914 mm) height dierence
must be maintained from the top of the uppermost chim-
ney section to the outside air inlet hoods.
NOTE: The maximum length of a 4 inch diameter duct is
20 feet. The duct can be extended up to a maximum of 40
feet by using 6 inch duct. A 4 inch to 6 inch adapter will be
needed. (not included).
NOTE: The minimum cross-sectional area of the 4 inch
inlet hood is 7.0 square inches.
Refer to Figures 3.14 and 3.15 when placing the outside
air inlet hoods.
An outside air kit is installed on each side of the replace.
• Cut 4-1/2 in. (114 mm) holes in outside wall to
accommodate air piping.
• Use 4 in. (102 mm) ex (not supplied) to directly connect
outside air to replace intake. Insulate the pipe to prevent
frost condensation.
• Use the supplied outside air inlet hoods.
• Seal between the wall and the pipe with silicone to
prevent moisture penetration and air leaks.
• Seal between the outside air inlet hoods and the house
with silicone to prevent air inltration.
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
outsidecombustionairfromwall,oororceilingcavity,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
theroomthroughthereplace.
• Locate outside air inlet hood to prevent blockage from
leaves, snow/ice, or other debris. Blockages could cause
combustion air starvation.

Installation of a ceiling restop is required:
• Refer to Figures 5.5, 5.6, 5.7.
• If the attic shield is pre-rolled continue. If it is a at part,
try and roll it up to aid in wrapping it around the chimney.
• Pre-bend all the tabs in at the top to 45°.
• Wrap the shield (around the chimney if already installed)
until you have an overlap and the three holes on each
side match up (large holes on top).
• Insert three screws into the matching holes to form a
tube starting at the bottom.
• Bend the tabs on the bottom of the tube inward to 90° to
maintain chimney air space.
• Rest the insulation shield on the ceiling restop below.
• Tape o any opening around the bottom.
If you wish to make a custom shield or barrier, follow
these guidelines:
• Metal is preferred, although any material sti enough to
hold back the insulation can be used.
WARNING! Risk of Fire! Use of cardboard or other
materialsthatcandeectunderhumidityorotherenvi-
ronmental conditions is not recommended.
• The shield or barrier must be tall enough to extend
above the insulation and prevent blown-in insulation from
spilling into the cavity and accommodate the amount of
insulation as required by the National Building Code.
• Maintain specied air spaces around chimney.
• Check instructions and local codes for further details.
F. Install Attic Insulation Shield
WARNING! Risk of Fire! You MUST install an attic insu-
lation shield when there is any possibility of insulation or
other combustible material coming into contact with the
chimney.
• DO NOT pack insulation between the chimney and the
attic insulation shield.
• Failure to keep insulation and other materials away from
chimneypipecouldcausere.
• DO NOTosetchimneyinsideinsulationshield.
• Combustible material may come in contact with the attic
insulation shield as long as the required clearances are
maintained to the chimney pipe.
Double-check the Chimney Assembly
Continue assembling the chimney sections up through
the ceiling restops as needed. While doing so, be
aware of the height and unsupported chimney length
limitations given under Section 5.
Check each section by pulling up slightly from the top
to ensure proper engagement before installing the suc-
ceeding sections. If they have been connected correct-
ly, they will not disengage when tested.
