1. Route a 3-wire 120V 60Hz power supply line
to the appliance junction box wires and ground
(Figures 15 ).
2. After wiring is complete, replace the appli-
ance 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 18
on page 9 illustrates two methods for con-
necting the gas supply. The flex-line method
utilizing the gas flex line provided with the
appliance is acceptable in the U.S., how-
ever, Canadian requirements vary depend-
ing on locality. Installation must be in com-
pliance with local codes.
Secure all joints tightly using appropriate
tools and sealing compounds (ensure pro-
pane resistant compounds are used in
propane applications).
Turn on gas supply and test for gas leaks,
using 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” posi-
tion. Either tighten or refasten the leaking
connection and retest as described above.
Figure 15
The gas control valve is located in the lower
control compartment. To access the valve
remove the refractory access panel and set
aside
(Figure 16 ).
The millivolt control valve has a ³⁄₈"
(10 mm) NPT thread inlet port. The electronic
control valve has a
¹⁄₂" (13 mm) NPT thread
inlet port and is fitted with a ¹⁄₂" x ³⁄₈" (13 mm
x 10 mm) NPT fitting. Plan connections not
utilizing the
³⁄₈" NPT open end of the gas flex
line shutoff, accordingly.
C. When the gas lines are tested and leak free,
be sure to rinse off the leak testing solution.
D. When the gas lines are tested and leak free,
observe the individual tongues of flame on the
burner. Make sure all ports are open and
producing flame evenly across the burner. If
any ports are blocked, or partially blocked,
clean out the ports.
Step 7. Outside Air Kits – Optional combustion
(outside make-up air) kits, Model FOAK-4 or
FAOK-4LD, may be used with these appliances.
Refer to the installation instructions packaged
with the air kits for specific installation informa-
tion. If used, 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 left 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.
Note: When installing the air duct vertically, DO
NOT terminate the duct closer than 3' below the
chimney top.
There is one hand operated shut-off valve lo-
cated in the left side of the fireplace opening
behind the screen. To open, pull the handle out.
The combustion air damper should be fully
open when the fireplace is in use and fully
closed when the fireplace is not in operation to
prevent outside air from entering your home.
