WIRING

CAUTION

Disconnect power supply before making 
wiring connections to prevent electrical shock 
or equipment damage.

Follow the wiring instructions furnished by the appliance 
manufacturer, if available, or use the following general 
instructions. Where these instructions differ from the 
appliance manufacturer, follow the appliance 
manufacturer instructions.

All wiring, including insulated quick connect terminals, 
must comply with applicable electrical codes and 
ordinances.

1.

Check the power supply rating on the gas control 
and make sure it matches the available supply. 
Install thermostat and other controls as required.

2.

When the gas control is installed on a hot surface or 
direct spark ignition system, attach the wire adapter 
provided to the wiring terminals. See Fig. 7 for the 
wire terminal location.

3.

Connect control circuit to gas control terminals. See 
Fig. 3 and 8, 9, or 10.

4.

Adjust the thermostat heat anticipator to 0.7, the rat-
ing stamped on the valve operator.

Fig. 7. Install wire adapter for hot surface or direct 

spark ignition systems. Pilot plug must be in the 

valve pilot opening.
