3.Unscrew compression titling from the pilot outlet (Fig. 4).

4.Slip the compression fitting over the tubing and slide out of the way.

5.Push the tubing into the pilot gas tapping on the outlet end of the control until it bottoms. While hold- ing tubing all the way in, slide compression flitting into place and engage threads—turn until finger tight. Then tighten one more turn with a wrench. Do not overtighten. Refer to Fig. 6.

6.Connect other end of the tubing to pilot burner according to the pilot burner’s manufacturer’s instructions.

NOTE: When replacing a gas control, cut off old com- pression fitting and replace it with the new com- pression fitting provided on the gas control. Never use the old compression fitting as it may not provide a gas-tight seal.

STARTUP AND CHECKOUT

WARNING

Fire or explosion hazard. Can cause property damage, severe injury, or death.

1.Do not force the gas control knob. Use only your hand to turn the gas control knob. Never use tools.

2.If the gas control knob will not operate by hand, the gas control should be replaced by a qualified service technician.

Gas Control Knob Settings

The gas control knob has two settings: OFF—prevents pilot and main burner gas flow. ON—permits gas to flow into the control body. Under control of the thermostat and intermittent pilot module, pilot and main burner gas flow is permitted.

NOTE: Gas controls are shipped with the gas control knob in the ON position.

WIRING

Follow the wiring instructions furnished by the appliance manufacturer if available or use the general instructions provided below.

All wiring must comply with applicable electrical codes and ordinances.

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

1.Check the power supply rating on the gas control and ensure it matches the available supply. Install transformer, thermostat, and other controls as required.

Turn on the System

Rotate the gas control knob counterclockwise to ON.

Turn on the Main Burner

Follow the instructions provided by the appliance manufacturer or turn the thermostat up to call for heat.
