Adjustment of Charbroiler, Standard-Griddle, and Uniform Hot-Top Burners and Pilots
The burner valves are not adjustable. The burner orice 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 insufcient 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.
