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 front of the burner.
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.
European Community:
If adjustment becomes necessary in the field, it should be done by a factory authorized and
trained technician who should seal the screw after the adjustment to safeguard against un-
authorized tampering by the end user.
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.
Daily:
1. Thoroughly clean back, sides, top and front of unit.
2. Clean grates daily.
Weekly
1. Clean unit thoroughly. Clean stainless steel or chromed surfaces with a damp cloth and polish
with a soft, dry cloth. A detergent may be used for cleaning. To remove discolorations, use a
non-abrasive cleaner.
2. To clean the drip pan: Remove the drip pan by grabbing the handle and pulling it out of the
opening in the front panel. To replace the pan, reverse this procedure.
3. Burner air shutter openings must be kept clean.
4. Main burner ports must be kept clean. To clean burners, boil them in a strong solution of lye
water for 15 to 20 minutes. Then either brush with a wire brush or clean gas ports with a sharp-
pointed metal instrument to insure open ports.
