SERVICE PROCEDURES AND ADJUSTMENTS
PILOT FLAME HEIGHT
1.
Locate the pilot adjustment screws below the
burner control knobs (one on each side) on the
front of broiler. It is not necessary to remove the
control valve cover as the adjustment access
holes are provided in the panel.
Fig. 25
2.
Locate the pilots at the top of the broiler heating
area.
3.
Monitor the pilots flame and burner lighting. Pilot
is in adjustment when it will stay on continually
and lights the burners without delayed ignition.
Approximate pilot flame height:
A.
Ceramic-Radiant Burner - 1/2" bubble
extending from the end of pilot tube.
B.
Infrared Burner - 3/4" from each side of the
pilot tee.
4.
If adjustment is necessary, rotate the screw
clockwise to decrease and counterclockwise to
increase flame height.
CERAMIC-RADIANT BURNER AIR
SHUTTER ADJUSTMENT
The efficiency of the burner depends on a delicate
balance between the air supply and volume of gas.
Whenever this balance is disturbed, poor operating
characteristics and excessive gas consumption may
occur. An air shutter on the front of the burner controls
the gas mixer balance. A yellow streaming flame on
the burner is an indication of insufficient primary air.
To correct this condition, loosen the shutter screw Fig.
26 and rotate the air shutter Fig. 27 open until the
flame begins to lift from the burner, then close the
shutter slightly and tighten the shutter screw. A proper
flame should be blue in color, well-defined and seated
on the burner port. A white-blue flame is a result of
excessive primary air.
NOTE:
The factory default air shutter positions are
half open natural; full open propane.

REGULATOR ADJUSTMENT
Shut off the gas before servicing the
unit.
NOTE:
Regulators come preset, but should be
checked anytime one is installed. Before adjusting
regulator, check incoming gas line pressure. Incoming
pressure must be 7-14" W.C. for natural gas and
11-14" W.C. for propane gas. If incoming pressure is
not correct, have the gas source checked and
adjusted as necessary. Make sure the regulator is
