setting . For example 175°F (79°C) to 200°F ( 9°C), to keep
griddle warm . Set thermostats, as required, for periods of
heavy load .
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 .
Pilot Adjustment
A pilot adjustment valve is located in the line from each
pilot combination valve . Pilot adjustment is accessible from
behind the lower front panel . First remove the two screws
securing the upper front panel to the body, in the upper
right and left hand corners, and then slightly raise the panel
to lift off . Remove to a safe area . Next, remove the two screws
securing the lower front panel to the body, in the upper right
and left hand corners and hinge the panel downwards .
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 .
