INSTALLATION

WIRING DIAGRAMS

No electrical power supply is required for the gas control to operate. 120 Volt AC power is needed for the fan switch and blower. The fan can be hard wired if desired. A terminal block is provided on the left hand side of the unit.

A three wire power cord can also be used and plugged into a suitable receptacle.

(Do not cut the ground terminal off under any circumstances.)

Caution: Ensure that the wires do not touch any hot surfaces and are away from sharp edges.
