It is best to frame your fireplace after it is positioned and
the vent system is installed. Use 2x4's and frame to local
building codes.
Combustible materials may be installed flush with the front
of the fireplace but must not cover any of the black face-
areas of the fireplace. Non-combustible material (brick,
stone or ceramic tile) may protrude in these areas.
Combustible objects, like furniture, placed in front of the
fireplace, should be kept a minimum of 48" away from the
front face.
In order to avoid the possibility of exposed insulation and
vapour barrier coming into contact with the fireplace body, it
is recommended that the walls of the fireplace enclosure
be 'finished' (ie: drywall/sheetrock) as you would finish any
other wall of the home. This will ensure that clearance to
combustibles is maintained within the cavity.
It is not necessary to install a hearth extension with this
fireplace system.
When roughing in the fireplace, raise the fireplace to ac-
commodate for the thickness of the finished floor materi-
als, 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 flashing accessories.
Proceed once the vent installation is complete.
1. Move the fireplace into position and secure using the
nailing tabs and/or secure to the floor through the 1/4"ø
holes located at either end of the base.
2. Route a 3/8" N.P.T. black iron gas line, 1/2" type-L
copper tubing or equivalent to the fireplace.
3. For ease of accessibility, an optional remote wall
switch or millivolt thermostat may be installed in a conven-
ient location. 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 de-
pends on wire size:
WIRE SIZE MAX. LENGTH
14gauge 100 feet
16gauge 60 feet
18gauge 40 feet
Attach the one lead to terminal 3 (located on the gas valve)
and the other lead to the vent safety switch wire ( located
loose in the valve compartment). See
FIGURE 3.
Do not connect either the wall switch, thermostat
or gas valve to electricity (110 volts).
4. Install rigid black pipe, 1/2" type-L copper tubing or, if
local codes permit, a 3/8" flex connector and shutoff valve
to the gas line and the fireplace gas valve. Seal and tighten
securely. An adapter fitting is required between the gas
valve and the copper tubing or flex connector.
DO NOT KINK
FLEXIBLE CONNECTOR. FIGURE 6.
5. Check for gas leaks by brushing on a soap and water
solution.
Do not use open flame.
Purge all gas lines with the glass door of the fire-
place open. Assure that a continuous gas flow is
at the burner before closing the door.
