Step 4. FIELD WIRING

Refer to Section A for millivolt appliances and
Section B for electronic appliances. The gas
valve is set in place and pre-wired at the
factory on both models.
A. Millivolt Wiring (See Figure 16 )
1. Appliance-mounted ON/OFF burner control
switch (rocker switch) is factory installed in
the modesty panel. Optional wall-mounted
switch, thermostat, or one of the optional
remote control kits may also be used.
2. If wall-mounted ON/OFF control or thermo-
stat is selected, mount it in a convenient
location on a wall near the fireplace.
3. Wire the control switch within the millivolt
control circuit using the 15 feet of 2 con-
ductor wire supplied with the unit.
Note: The supplied 15 feet of 2 conductor
wire has one end of each conductor con-
nected to the gas valve circuit and the other
end of each conductor placed loose inside
the lower compartment of the unit.
Caution: do not connect the optional wall
switch to a 120V power supply.
4. If an optional control switch is installed,
turn the appliance-mounted ON/OFF burner
control switch to the OFF position.

1. Route a 3-wire 120Vac 60Hz 1ph power
supply to the appliance junction box.
2. Open the control compartment access
panel, by actuating the spring-loaded
magnetic catches securing the panel,
gently depressing the outer top corners
of the panel until the catches "pop" the
panel free and allowing it to swing out
and down to open.

6. Install a field-provided strain relief in the
cabinet knockout opening for the protec-
tion of the power supply wires.
7. Connect the power supply wires to the
receptacle as shown in Figure 18 on
page 11.
