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.
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.
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”.
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.
Do not permit fans to blow directly on the unit. Wherever possible, avoid open windows next to the
unit’s sides or back. Avoid wall type fans which create air cross-currents within the room.
It is also necessary that sufficient air should be allowed to enter the room to compensate for the
amount of air removed by any ventilating system. Otherwise, a subnormal atmosphere will occur,
adversely affecting operation and causing undesirable working conditions.
A properly designed and installed hood will act as the heart of the ventilating system for the room or
area in which the unit is installed, and will leave the unit independent of changing draft conditions.
All valves must be checked and lubricated periodically. Consult the authorized service
representative in your area.
