Adjustment of Thermostatic-Griddle Burners and Pilot
The thermostatic burner valve is adjustable (see page 35). The burner orice is of the xed type, sized for the type of
gas and the operating altitude. To adjust the burner air-gas mixture, loosen the screw that secures the air shutter on the
mixer face and rotate the mixer cap to obtain a clear, stable blue ame with a distinct inner cone at each port. Exces-
sive primary air causes “blowing” (the ames leaving the ports), while insufcient primary air causes a soft or yellow
tipped ame.
The pilot(s) and pilot-runner(s) are located near the front of the burners, but the pilot adjustment valve is located in the
gas line between the safety switch and the pilot. If the pilot needs adjustment, do the following:
1. Remove the control knobs, and remove the valve panel (see page 30).
2. If necessary, light the pilot.
3. Locate the pilot adjustment valve (see drawing below). Turn the pilot adjustment screw counterclockwise to increase
the size of the pilot ame, or clockwise to decrease the size of the pilot ame. The pilot ame should be about 1/2”
high with a slight yellow tip, and cover the thermocouple tip. The rst indication of over-adjustment is when the ame
tip becomes more yellow and begins to generate carbon, which appears as rising black streaks. Continued over-
adjustment leads to unstable lifting and a blowing condition.
4. Replace the valve panel and control knobs.
