3.9.3 Vented Cavity and Komfort
Zone Kit 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.
•
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
•
Minimum rough framing dimensions for #KZK-054, #KZK-
1510A, #HTK-INT, #HTK-EXT, and vented cavity installation are
shown below. These dimensions 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 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. A lintel must be used over
the top of the appliance to support the added weight of the
masonry construction above the fireplace.
•
Installation of CW50-SHD steel framing is required (included with
the unit).
3.9.3.1 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 4-1/4” (108mm) deep recess is
constructed above the fireplace when installed with the KZK kit(s),
HTK kit(s), or Vented Cavity option.
