SERVICE PROCEDURES AND ADJUSTMENTS
The supply pressure (upstream of the regulator)
should be 7-9” W.C. for natural gas and 11-12” W.C.
for propane gas. At no time should the griddle be
connected to supply pressure greater than ½ psig
(3.45 kPa) or 14” W.C.
Graphic shows pressure plug location.
NOTE: MSA models are in same locations. There are no shut off valves.
BURNER ADJUSTMENT
For efficient burner operation, it is important that a
proper balance of gas volume and primary air supply
is maintained to give complete combustion.
Insufficient air supply results in a yellow streaming
flame. Primary air supply is controlled by the air
shutter on the front of the burner venturi. Loosen the
screw on the venturi and adjust the air shutter to just
eliminate yellow tips on the burner flames. Lock the
air shutter in place in place by tightening the screw.
Repeat this procedure as necessary with all burners.
