D. Standing Pilot Ignition System Wiring
• This standing pilot ignition system wiring does not require
a 110 VAC supply to operate. A wiring diagram is shown
in Figure 10.3.
• It is recommended that a 110 VAC junction box be installed
for use with a fan or remote control. (See Figure 10.4 for
junction box wiring.)
CAUTION
Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing.
