A. Recommendation for Wire
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
