2. Locating Fireplace & Chimney
Location of the replace and chimney will affect performance.
• 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 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 4 and 5.

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 recommends that the chase be well insulated using batt type insulation between the joists.
Construction of the chase may vary with the type of building. These instructions are not substitutes for the requirements 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 3.3.)
Vapor and air inltration barriers should be installed in the
chase as per regional codes for the rest of the home. Additionally, 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.
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).
• 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.

F. Frame the Fireplace
NOTICE: Hearth extension design must be determined
before installation of replace.
If the replace is placed on the oor the maximum height
of a nished raised hearth is 7-5/8 in., if you want a
higher raised hearth the replace must be placed on a
platform.
Figure 3.12 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 3.3. Any framing across the top of the replace must be above the level
of the top standoffs.
The
nished cavity depth must be no less than:
• SB60 - 28 in. (711 mm) from the nished backwall to
the outside of front wall framing.
• SB80 - 28 1/2 in. (724 mm) from the nished backwall
to the outside of front wall framing.
DO NOT install header until the replace is in position.

I. 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 uppermost chimney section to the outside combustion air inlet.
Refer to Figures 3.16 and 3.17 when placing the outside
air inlet hood.
The outside air kit is installed on the left hand side of the
replace.
• Cut a 4-1/2 in. (114 mm) hole in outside wall to
accommodate air piping.
• Use 4 in. (102 mm) ex (not supplied) to directly connect
outside air to replace intake. Insulated ex can be used
to reduce 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 inltration.
CAUTION! Risk of Fire or Asphyxiation! DO NOT draw
• 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.
CAUTION! Risk of Cuts/Abrasions. Wear protective
gloves and safety glasses during installation. Sheet metal
edges are sharp.

Straight chimney sections may be secured with screws. Keep chimney sections from separating or twisting.
• Measure the shift needed to avoid the overhead obstruction. Refer to dimension A in Figure 4.2.
• Find the appropriate A dimension listed in Table 4.3. The B dimension coinciding with the A dimension measurement in
Table 4.3 represents the required vertical clearance needed to complete the offset/return.
• Read across the chart to nd the number of chimney sections/model numbers needed between the offset and return.
Example:
Your “A” dimension from Figure 4.2 is 14-1/2 in. (368
mm). Using Table 4.3 the dimension closest to, but not
less than 14-1/2 in. (368 mm) is 15-3/4 in. (400 mm) using
a 30° offset/return.
You determined from the table that you would need
36-5/8 in. (930 mm) (Dimension “B”) between the offset
and return.

safe operation and cause overheating and re.
Attach either a straight chimney section or an offset to
the top of the replace (depending on your installation
requirement). Chimney sections are locked together by
pushing downward until the top section meets the stop
bead on the lower section.
The inner ue is placed to the inside of the ue section
below it. The outer casing is placed outside the outer casing of the chimney section below it. See Figure 5.2.
NOTICE: Chimney sections cannot be disassembled once
locked together. Plan ahead!
• Lock chimney sections and/or offsets/returns together by
pushing downward until the top section meets the stop
bead on the lower section.
• Pull on the top section to make sure it is fully engaged
and will not separate.
• You may use #6 or #8 sheet metal screws no longer than
1/2 in. (13 mm) to fasten chimney sections together. Do
NOT penetrate inner ue.

• DO NOT offset chimney inside insulation shield.
• Combustible material may come in contact with the attic
insulation shield as long as the required clearances are
maintained to the chimney pipe.
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 off any opening around the bottom.
