Step 4. FIELD WIRING
Refer to Section A for millivolt appliances and
Section B for electronic appliances.
A. Millivolt Wiring (See Figure 43):
1. Install and wire in the burner control switch.
Install either "a" or "b" below, NOT BOTH
(installing both may result in improper burner
operation).
a. Optional OFF/ON Switch - Install the
OFF/ON burner control switch (rocker
switch) as shown in Figures 43 &
44.
b. Optional Wall Switch, Wall Thermostat
Or Remote Control Receiver - Install
snap bushing (provided in Electrical
Outlet Kit) into control switch knock-
out in side panel (see Figures 13,14 &
45). Wire the optional control switch
within the millivolt control circuit (as
shown in Figure 43) using the 15 feet
of 2 conductor wire supplied (route
wires through the snap bushing to
the optional control switch). Mount
the optional control switch or wall
thermostat in a convenient location
on a wall near the fi replace.
CAUTION: DO NOT CONNECT OPTIONAL
CONTROL SWITCH TO 120VAC POWER
SUPPLY.
2. Install the junction box and receptacle outlet
to the left of the valve in the front (for optional
blower kit). See junction box and receptacle
outlet as explained in steps 1-11 for (B)
Electronic Wiring (on this page).
CAUTION
Label all wires prior to disconnec-
tion when servicing controls. Wiring
errors can cause improper and dan-
gerous appliance operation.

B. Electronic Wiring (See Figures 45 & 46)
Notes:
• The electronic appliance must be connected
to the main 120 VAC power supply.
• The junction box can be installed in any of the
4 outside corners of the control compartment (it
can be found factory installed in the right front
corner viewed from the valve access side (where
it should be reinstalled if an optional blower kit
is installed).
1. Route a 3-wire, 120 VAC, 60 Hz, 1 ph power
supply to the location on appliance where
junction box is to be installed.
2. Open the control compartment access panel
(see Control Compartment Access Instruc-
tions on Page 27).
3. Remove the junction box/outlet receptacle
assembly by removing the securing screw at
the front right corner of the unit. See Figure
45.
4. Remove the outlet receptacle from the
junction box by removing the two securing
screws.
5. Install a fi eld-provided strain relief in the
cabinet knockout opening for the protection
of the power supply wires.
6. Connect the power supply wires to the
receptacle as shown in Figure 46 on Page
26.
7. Connect the ground supply wire to the green
wire attached to the outlet receptacle’s
green ground screw.
8. Wire and install the outlet receptacle to
junction box. Next, install into the chosen
corner of the control compartment as shown
in Figure 45.
9. After the receptacle/junction box wiring is
complete, install the fi eld-provided metal
junction box cover plate (see Figure 45).
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 on top
of the appliance.
IMPORTANT NOTE
The gas valve OFF/ON switch is
shown in Figure 46 on Page 26. It
is integral with the gas valve and
should be set to the ON position.
