3.5 Rough Framing
3.5.1 Rough-in Wall Enclosure
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.
•
METAL-FAB VENT SYSTEM:
If installing Metal-Fab vent pipe,
an adapter must be used. This will change the minimum depth
for the wall enclosure rough opening from 22” (558mm) to 26”
(660mm) in order to maintain the required vent pipe clearances
•
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 fireplace platform.
If using a safety
screen only, the hearth may be flush with the finishing edge. If
using a surround, the bottom of the fireplace surround must be
level with finished hearth extension for proper fit of the optional
surround.
•
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.
3.5.1.1 TV Recess Construction
WARNING: All clearances to venting must be maintained.
Mounting a television above a fireplace is a common practice. Mantel
depth, ceiling heights, and wall and mantel construction material all
affect television surface temperatures. 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.
The drawing below shows the minimum dimensions for standard
installation of the fireplace. Anything above the minimum enclosure
height of 60” (1524mm) can be capped off or recessed. If installing a
KZK kit or using a Vented Cavity option, the framing dimensions may
different than the minimum dimensions shown below.
