4. LIGHTING INSTRUCTIONS

Lighting instructions are located on the rear panel. Access to the pilot valves are gained through openings in the front panel. Access to the pilot burner is gained by removing the top grate.

Lighting Pilot Burner:

1.Turn all burners to the “OFF” position.

2.Turn on the main gas supply to the unit.

3.Light the pilot and adjust the pilot regulating valve to give a stable pilot flame.

4.If the pilot is out, turn all control knobs to the “OFF’ position. Wait 5 minutes before attempting to light the pilot.

5.To adjust the pilot flame, turn adjusting screw on the pilot valve to increase or decrease the size of the pilot flame. Adjust until the pilot flame is approximately ½” (1 2mm) to 3/4” (19mm) tall.

Burner Ignition

Since the burner is lit from a constantly burning pilot, turn the control knob to “HI” to put the unit into operation; then adjust to any desired position between “LO” and “HI”.

Main Burner Air Supply:

For efficient burner operation, a proper balance of gas volume and primary air supply must be maintained which will result in complete combustion. Insufficient air supply results in a yellow streaming flame. Primary air supply is controlled by an air shutter on the burner.

Loosen the screws on the front of the venturi, and adjust the air shutter to eliminate the yellow on the burner flame. Lock the air shutter in place by tightening the screws.

All burners are lit from constantly burning pilots, turning the control valve as desired is all that is required to put the unit in service.
