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.

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
