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.)

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

CAUTION

Shock Risk

• Replace damaged wire with type 105° C

rated wire.

• Wire must have high temperature

insulation.

Note:

Do not wire 110V to the millivolt valve (standing pilot)!

This will damage the valve.

Optional Accessories Requirements

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