1. Route a 3-wire 120V 60Hz power supply
line to the appliance junction box wires and
ground (Figures 13 ).
2. After wiring is complete, replace the appliance
junction box cover and secure with the hex head
screws previously removed.
Step 6. Connecting Gas Line – Make gas line
connections. All codes require a shut-off valve
mounted in the supply line. Figure 16 on page
9 illustrates the method for connecting the gas
supply. The flex-line method utilizing the gas flex
line provided with the appliance is acceptable
in the U.S., however, Canadian requirements
vary depending on locality. Installation must
be in compliance with local codes.
The gas control valve is located in the lower
control compartment. To access the valve
remove the refractory access panel and set
aside (Figure 14 ). The control valve has a
3/8" (10 mm) NPT thread inlet port.
Secure all joints tightly using appropriate
tools and sealing compounds (ensure propane
resistant compounds are used in propane
applications).
Turn on gas supply and test for gas leaks, us-
ing a gas leak test solution (also referred to as
bubble leak solution).

Note: Using a soapy water solution (50%
dish soap, 50% water) is an effective leak test
solution but it is not recommended, because
the soap residue that is left on the pipes/fittings
can result in corrosion over time. Never use
an open flame to check for leaks.
A. Light the appliance (refer to the lighting
instructions label in the control compartment
or in the Homeowner's Care and Operation
Instructions).
B. Brush all joints and connections with the gas
leak test solution to check for leaks. If bubbles
are formed, or gas odor is detected, turn the
gas control knob to the "OFF" position. Either
tighten or refasten the leaking connection and
retest as described above.

C. When the gas lines are tested and leak free,
be sure to rinse off the leak testing solution.
Step 7. Optional Outside Air Kits – Combus-
tion (outside make-up air) kits, Model FOAK-4
or FAOK-4LD, may used with these appliances.
Refer to the installation instructions packaged
with the air kits for specific installation infor-
mation. The outside air kit must be installed
before the fireplace is framed and enclosed in
the finished wall.
Outside air drawn into the fireplace supplies air
to the fire for combustion. Only one combus-
tion air duct on the right side of the fireplace
is necessary if installed.
If additional length of duct is necessary, pur-
chase locally available U.L. Class 0 or Class 1
metallic ducting. The duct may extend up to
50' (15.24 m) in any direction.
There is one hand operated air gate shut-off, for
utside make-up air, located at the right side of
the fireplace opening behind the screen. To open,
lift and pull the handle out. The combustion air
damper should be open when the fireplace is
in use and, to prevent outside air from entering
your home, fully closed when the fireplace is
not in operation.
