3.6 OPTIONAL WALL SWITCH INSTALLATION
!
WARNING
Do not connect either the wall switch, thermostat or gas valve directly to 110 volt electricity.
For ease of accessibility, an optional remote wall switch may be installed in a convenient
location. A 20ft length of millivolt wire is connected to the gas valve and wall switch.
However, if a greater length is required route 2-strand (solid core) millivolt wire through
the electrical hole located at the bottom left side of the unit. The recommended maximum
lead length depends on wire size:
Attach the two leads to terminals 1 and 3 located on the gas valve.

Minimum clearance to combustible construction from appliance and vent surfaces:
Sides, back, bottom and top of the unit
0"
Recessed depth
22"
All around the vent pipe*
2"
Enclosure top
45 1/2"
Ceiling
72" from bottom of unit
*HORIZONTAL VENT SECTIONS:
A minimum clearance of 2" all around the vent pipe on all horizontal runs to com-
bustibles is required. Use
fi
restop spacer W010-1778 (supplied).
VERTICAL VENT SECTIONS:
A minimum of 1" all around the vent pipe on all vertical runs to combustibles is required
except for clearances in appliance enclosures. Use
fi
restop spacer W500-0367 (not supplied).
It is best to frame your appliance after it is positioned and the vent system is installed. Use 2x4's and frame to local
building codes. It is not necessary to install a hearth extension with this appliance system.
When roughing in the appliance, raise the appliance to accommodate for the thickness of the
fi
nished
fl
oor materials,
i.e. tile, carpeting, hard wood, which if not planned for will interfere with the opening of the lower access door and the
installation of many decorative
fl
ashing accessories.
Combustible materials may be installed
fl
ush with the front of the appliance but must not cover or protrude past any
of the black face-areas of the appliance. Non-combustible material (brick, stone or ceramic tile) may protrude in these
areas.
!
WARNING
In order to avoid the possibility of exposed insulation or vapour barrier coming in contact with the
appliance body, it is recommended that the walls of the appliance enclosure be “finished” (ie:
drywall / sheetrock), as you would finish any other outside wall of a home. This will ensure that
clearance to combustibles is maintained within the cavity.
Do not notch the framing around the appliance stand-offs. Failure to maintain air space clearance
may cause over heating and fire. Prevent contact with sagging or loose insulation or framing and
other combustible materials. Block opening into the chase to prevent entry of blown-in insulation.
Make sure insulation and other materials are secured.
