Adjustment of Charbroiler, Standard-Griddle, and Uniform Hot-Top Burners and Pilots
The burner valves are not adjustable. 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. Excessive primary air causes
“blowing” (the ames leaving the ports), while insufcient primary air causes a soft or yellow tipped ame.
The pilots are near the front of the burners, and are held in position by brackets. To adjust a pilot ame, insert a
screwdriver through the opening in the valve panel between the control knobs and turn the appropriate pilot adjustment
screw counterclockwise to increase the size of the pilot ame, or clockwise to decrease the size of the pilot ame. The
maximum ame size is approximately 3/4” with a slight yellow 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.
Figure 17
Pilot-ame outage is often due to an unstable ame caused by over-adjustment to the point where the pilot ame is
leaving its port, or “blowing off.” Sometimes the pilots are increased too much in an effort to improve ignition, resulting in
this unstable condition.
