Building Around the Fireplace
Building Checklist
The following building checklist is a quick reference for a typical 77HH series fireplace installation. This list is
not exhaustive and does not supplement thorough review of the installation manual.
Fireplace Location:
Ensure the location allows for min. 40” clearance from viewing area to furniture
and other combustibles. Make sure a clear path is established to allow the fireplace to be safely
transported to installation location.
Exhaust Vent:
Confirm vent size (5”x8”, or 3”x5” for Power Vent), vent clearance (1” on sides and
bottom, 3” on top), vent configuration, and termination location.
Height from Floor:
Fireplace leg height is 9
13
/
16
” (to bottom viewing area). Legs cannot be
removed/altered. If desired viewing area location on the wall is higher than 9
13
/
16
”, a platform can be
built for the fireplace to stand on.
Chase Floor/Platform:
Fireplace can stand on the chase floor or a platform. Floor or platform must be
able to bear the weight of the fireplace. It can be constructed out of wood, concrete, metal, or any other
solid materials (not required to be non-combustible).
Chase Construction:
No materials can be attached directly to the fireplace (exception:
5
/
8
” Type X
Drywall). The area of the chase interior must be min. 200 square inches at any given point within the
chase.
Framing:
Adhere to minimum framing dimensions (or greater). The first 10
7
/
16
” above the top of the
fireplace viewing area must always be non-combustible framing. For recessed fireplaces, do not exceed
12” max. front overhang depth limit. For Corner and TS models, side overhang has no limit. No material
is permitted to extend past the metal lip surrounding the fireplace viewing area.
5
/
8
” Type X Drywall Requirements:
One layer of
5
/
8
” Type X Drywall (or equivalent) must be installed
on the exterior of the chase framing.
5
/
8
” Type X Drywall (or equivalent) may be fastened to the top
framing stand-off(s) only, with 1" self-tapping drywall screws 16'' on center.
TV/Artwork:
TV/Art must be min. 4” above top of fireplace viewing area for flush-mounted TVs, and 12”
for TVs recessed into the wall. First 10
7
/
16
” min. above the viewing area must have non-combustible
framing (top front metal stand-off + non-combustible studs).
Gas Supply Line and Power Location:
Locate gas line with manual shut off according to local code.
Power provided by a duplex outlet receptacle (120V, 15 amp, 60Hz) in same area as gas line.
Access Panel:
An access panel is highly recommended to access gas and electrical components for
servicing. Depending on the model, access panel can be placed at side or back of the fireplace within
3 feet of the pilot. Access panel, or some other form of clear access to the chase, is required for power-
vented fireplaces. Size recommendation: as large as possible depending on application. Min.
recommended size 10”x10”.
Heat Release:
Crucial for Cool Wall Technology.
Must start within 6” (max.) from the chase’s ceiling.
Min. horizontal heat release size is 200 sq.in. of net free air space (vertical heat release requires 260
sq.in.). Height of the heat release must not exceed 1/3 of the width.
Air Intake:
Must be located at or below level of double glass fans. Min. 200 sq.in. of net free air space.
Finishes:
For finishes flush to the fireplace, no clearances are required. For finishes where the fireplace
is recessed to the finish, maintain
1
/
8
" from the finish to the front face of the fireplace.
