C. Intellifi re Ignition System Wiring
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 3 volt AC transformer,
which requires the installation of the supplied junction box.
It is highly recommended that the junction box be installed
at this time to avoid reconstruction.
A. Intermittent Pilot Ignition (IPI) System
The gas control system used with this model is Intermit-

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

• Replace damaged wire with type 105º C rated
wire.
• Wire must have high temperature insulation.
WARNING
NOTE:
Flames too close to the ceramic
insulators can cause nuisance lock-
outs and electrode failure.
IPI IGNITION
FLAME

ROD
Shock hazard.
• DO NOT connect 120V directly to ignition
components.
• System failure will occur.
• Warranty will be voided.
WARNING
Wall Switch
Position the wall switch in the desired position on a wall.
Using 14 AWG or greater wire, following local codes, wire
the wall switch to the 110 VAC pigtail wires at the rocker
switch. The ground wire must be securely attached to the
ground stud in the junction box. DO NOT run 110-120
VAC to the valve. The valve system runs off 3 volts pro-
vided by the 3 volt transformer. See Figure 10.2.
• A 110-120 VAC circuit for this product must be protected
with ground-fault circuit-interrupter protection, in compliance
with the applicable electrical codes, when it is installed in
locations such as in bathrooms or near sinks.
