A. Recommendation for Wire
This appliance requires 110-120 VAC to be wired to the junc-
tion box either for use of optional accessories (standing pilot
ignition) or for proper operation of the appliance (Intellifi re
ignition).
Open the control access panel to view wiring system and
gas valve. If this appliance has a red or black ignitor button
this appliance has a standing pilot ignition system. If there is
no red or black ignitor button, this appliance has an Intellifi re
ignition system.
Battery polarity must be correct or module damage will
occur.
CAUTION
B. Connecting to the Appliance
Shock Risk
Explosion Risk
Do NOT wire 110V to valve.
Do NOT wire 110V to wall switch
• Incorrect wiring will damage millivolt
values.
• Incorrect wiring will override IPI safety
lockout and may cause explosion.
WARNING
C. Intellifi re Ignition System Wiring
This appliance requires a 110 VAC supply to the appliance
junction box for operation. (See Figure 10.1 for a wiring dia-
gram and Figure 10.3 for junction box wiring.)
This appliance is equipped with an Intellifi re control valve
which operates on a 3 volt system.
This appliance is supplied with a battery pack and a 3 volt
AC transformer, which requires the installation of the sup-
plied junction box. It is highly recommended that the junction
box be installed at this time to avoid reconstruction.
The battery pack requires two D cell batteries (not included).
Batteries cannot be placed in the battery pack while using
the 3 volt AC transformer. Conversely, the transformer must
be unplugged if the battery pack is used.
Optional Accessories Requirements
Wiring for optional accessories should be done now to
avoid reconstruction.

CAUTION
Shock Risk
• Replace damaged wire with type 105° C
rated wire.
• Wire must have high temperature
insulation.
CAUTION
• This appliance may be used with a wall switch, wall
mounted thermostat and/or a remote control.
• If using thermostat use one compatible with a millivolt gas
valve system.
• Follow parameters for locating thermostat (see individual
thermostat instructions) to ensure proper operation of
appliance.
• Use low resistance thermostat wire for wiring from ignition
system to the wall switch and thermostat.
• Keep wire lengths short as possible by removing any
excess wire length.
• Low voltage and 110 VAC voltage cannot be shared within
the same wall box.
Note: This appliance must be electrically wired and
grounded in accordance with local codes or, in the absence
of local codes, with National Electric Code ANSI/NFPA
70-latest edition or the Canadian Electric Code CSA
C22.1.
