Main burner air supply:
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.
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.
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.
5. MAINTENANCE
CAUTION: Use only non-abrasive cleaners. Abrasive cleaners could scratch the finish of
your unit, marring it ’ s appearance and making it susceptible to dirt accumulation. Do Not
use steel wool, other abrasive cleaners or cleaners/sanitizers containing chlorine, iodine,
ammonia or bromine chemicals as these will deteriorate the stainless steel and glass
material and shorten the life of the unit.
Daily:
Weekly:
1. Thoroughly clean back, sides, top and front of unit.
2. Clean grates daily.
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.
CAUTION: Clean the regulator at least once a month. Make sure the vent opening is open
and not blocked in any way. Failure to do so will cause variations in pressure. Your unit will
not function as well and it could shorten the life of the product.
