INSTALLATION
1) Frame in the enclosure for the unit with framing material.
IMPORTANT: Header must be metal stud. All other framing may
be of combustible type such as 2x4 / 2x6 framing materials.
Note: When constructing the framed opening, please ensure there
is access to install the gas lines when the unit is installed.
2) For exterior walls, insulate the enclosure to the same degree as the
rest of the house, apply vapour barrier and drywall, as per local instal-
lation codes. (Do not insulate the fi replace itself.)
WARNING: Failure to insulate and add vapor barriers to the inside
of the exterior wall will result in operational and performance
problems including, but not limited to: excessive condensation
on glass doors, poor fl ame package, carbon, blue fl ames etc.
These are not product related issues.
3) The unit does not have to be completely enclosed in a chase. You
must maintain clearances from the vent to combustible materials: See
"Clearances" section. Combustible materials can be laid against the
side and back standoffs and the stove base.
4) The combined total of non-combustible facing materials (ie. hardi-
board + tile, slate, etc) may be brought up to and overlap the face of
the unit (top and bottom). The minimum thickness = 1/2"
to a maximum thickness = 1-1/2", as shown in the diagram below.
If material is thicker than 1-1/2" - it will not be possible to
mount the faceplace.
5) When fi nishing around the faceplate, if material such as brick, stone,
etc. extend past the faceplate depth - the minimum opening
dimensions noted below must be adhered to, this is to assure
removal of the faceplate.

FRAMING & FINISHING
6) Determine the total thickness of facing material (eg. hardiboard +
ceramic tile) to ensure the fi nished surface is fl ush with the front
edge of the unit (see diagram below). If necessary, side and top
nailing strips are adjustable, loosen the 1/4" screws and adjust.
Total non-combustible facing allowable: Min. = 1/2"
See diagram below.
