ADJUSTMENTS
NOTE: Each griddle has been factory tested and adjusted
prior to shipment It may be necessary to further adjust the
unit as part of a proper installation Such adjustments are the
responsibility of the installer Adjustments are not considered
to be defects in material and workmanship, and they are not
covered under the original equipment warranty
Turning the small screw in the pilot adjusting valve clockwise
reduces the amount of gas provided to the pilot(s) Turning
the small screw counterclockwise increases the gas provided
to the pilot(s) The gas should be adjusted to a 7/16 (11 mm)
inch long flame, to ensure that the flame engulfs the top of
the flame sensor
Burners should always be warm when an adjustment to
air shutters is made To adjust air shutters, loosen the small
screw along the side of the burner near the orifice Lifting
flames on the burner indicates too much air and this air
shutter should be in a more closed position Yellow tips on
the flames indicate not enough air and the air shutter should
be in a more open position When the air shutter adjustments
are complete on each burner, retighten the air shutter screw
so that the correct setting is locked in place
Pilot Adjustment
A pilot adjustment valve is located in the line from each
pilot combination valve Pilot adjustment is accessible from
