This appliance requires 110-120 VAC be wired to the 
junction box either for use of optional accessories (stand-
ing pilot ignition) or for proper operation of the appliance 
(Intellifi re ignition). Refer to Figure 10.1 to determine if the 
appliance uses an Intellifi re ignition system or Standing 
Pilot ignition system.

Open the control access panel to view wiring system and 
gas valve. If this appliance has a red or black ignitor button 
(as noted in Figure 10.1) 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.

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 C221.1.

This appliance requires a 110 VAC supply to the appliance 
junction box for operation. A wiring diagram is shown in 
Figure 10.2.

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 junc-
tion box be installed at this time to avoid reconstruction.

The battery pack requires two D cell batteries (not 
included). 

Wire 110V to electrical junction box.
Do NOT wire 110V to valve.
Do NOT wire 110V to wall switch.
•  Incorrect wiring will damage millivolt valves.
•  Incorrect wiring will override IPI safety lockout 

and may cause explosion.

Battery polarity must be correct or module damage will occur.

Wiring for optional accessories should be done now to 
avoid reconstruction.

•  This appliance MUST be used with a wall switch 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.

Label all wires prior to disconnection when servicing controls. 
Wiring errors can cause improper and dangerous operation. 
Verify proper operation after servicing.

Shock hazard.
•  Replace damaged wire with type 105º C rated wire.
•  Wire must have high temperature insulation.

•  Use low resistance thermostat wire for wiring from igni-

tion 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: Batteries cannot be placed in the battery pack 
while using the 3 volt AC transformer. The transformer 
must be unplugged if the battery pack is used or battery 
life will be reduced.
