3.5 Rough Framing
WARNING: Provide adequate clearance in front of the fireplace for
barrier removal, component access, gas line installation, service
access, etc.
CAUTION: Cold air transfer area. The surround fireplace chase
must comply with all clearances as outlined in this manual, and be
constructed in compliance with local building codes. Outside walls
should be insulated to prevent cold air from entering room.
•
Determine if the fireplace face will be flush with the wall surface
(where the wall surface and fireplace will be covered with
noncombustible material, such as tile) or the fireplace face will
be flush with framing (flat wall appearance).
•
Rough framing dimensions for should allow for wall covering
thickness and fireplace facing materials. Adjust rough opening
size as necessary to maintain minimum clearance requirements.
•
Floor protection in front of the fireplace is not required.
Combustible material may be used if installing a hearth
extension. Consider the thickness of the hearth extension
finishing material if building a fireplac
e platform. The bottom
of the fireplace must be level with finished hearth extension for
proper fit of the safety barriers.
•
The bottom of the fireplace must be placed directly on a wood
or non-combustible surface (not linoleum or carpet). If this
appliance is to be installed directly on carpeting, tile, or other
combustible material other than wood flooring, this appliance
shall be installed on a metal or wood panel extending the full
width and depth of the appliance.
•
This fireplace may be elevated off the floor, provided it is
properly supported by framing materials and maintains ceiling
clearances. If installed above floor level, a solid, continuous
platform must be constructed below the fireplace.
•
If masonry (optional) is to be used, prepare the foundation
necessary for the full masonry load. A lintel must be used over
the top of the appliance to support the added weight of the
masonry construction above the fireplace.
•
If you are planning an installation with the use of an exterior
and/or interior kit, the minimum dimensions listed in this section
will apply for your framing installation. You will still need to
remove the cover plates as instructed in Section 3.8 Heat Transfer
Kit(s) Cover Plate(s) on page 18.
3.5.1.1 TV Recess Construction
WARNING: All clearances to venting must be maintained.
Mounting a television above a fireplace has become a common
practice. Television surface temperatures are affected by mantel
depth, ceiling heights, and wall and mantel construction material.
Most television manufacturers specify in their instructions that a
television should not be installed on, near, or above a heat source.
Television location rests solely on the homeowner. It is the home
owner’s responsibility that the preferred TV mounting and mantel
design will not exceed the listed maximum operation temperature of
their electronic goods.
Tests performed determined that surface temperatures did not
exceed 150°F (66°C) when a 4¼” (108mm) deep recess is constructed
above the fireplace.

*27-1/4” (692mm) represents minimum distance from fireplace front to back wall
of framing (minimum depth required for wall surface to cover fireplace front).
If you desire wall surface to be flush with fireplace face, subtract 1/2” (standard
drywall depth) from this dimension. If using another material, adjust accordingly.
