NOTE: Top clearance through outside wall is 3 inches.
ATTENTION: Cold climate installation recommendation: When
installing this unit against an exterior wall, the exterior wall must
be insulated to conform to applicable insulation codes. The
fireplace outer wrapper is not considered a thermal barrier and
can allow air infiltration. Care should be taken to properly seal
the chase area so air infiltration is kept to a minimum and drafts
do not occur through the fireplace.
Vent Runs
In planning the installation, you must install certain components
before the fireplace is secured in position. These include the
direct-vent system, gas piping, and the electrical wiring.
The appliance can be mounted on any of the following surfaces:
1. A flat, hard combustible or non-combustible surface.
2. A raised wooden platform.
3. Four corner supports(such as masonry blocks). These supports
must be positioned so they contact all four perimeter edges on
the bottom of the unit.
