LIGHTING INSTRUCTIONS
Lighting pilot
The pilot light on the appliance has been set at the factory. A screwdriver may be required for the
first lighting to adjust the flame for your elevation.
1. Turn off the manual valve and wait 5 minutes to clear the gas.
2. Turn all knobs to the "OFF" position.
3. Hold an ignition source (match) at the pilot. When the flame is established, remove the ignition
source.
4. Turn the burner knobs to "ON". If the burner does not ignite, promptly open the pilot valve
more. If the pilot flame appears larger than necessary, turn it down and reset burner ignition. The
pilot flame should be as small as possible but large enough to guarantee reliable ignition of the
burners when the knobs are turned to "ON".
Lighting main burner
To light burner, turn knob to “ON.” Then adjust to the desired flame level. The range of adjustment
is virtually infinite between “ON” and “OFF”.
Main burner air supply:
1. 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 front of the burner.
2. Loosen the screws on the front of the burner and adjust the air shutter to just eliminate the
yellow tips of the burner flame. Lock the air shutter in place by tightening the screws.
CAUTION
All burners are lit from constantly burning pilots. Turning the valve to the desired flame height is all
that is required to put the unit in service.
Do not permit fans to blow directly at the unit. Wherever possible, avoid open windows next to the
units' sides or back. Avoid wall type fans which create air cross-currents within a 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 atmospheric pressure will
occur, 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. This must be done by an authorized service
representative in your area.
