Adjustment of Charbroiler, Standard-Griddle, and Uniform Hot-Top Burners and Pilots
The burner valves are not adjustable. The burner orifice is of the fixed 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 flame with a distinct inner cone at each port. Excessive primary air causes “blowing” (the flames
leaving the ports), while insufficient primary air causes a soft or yellow tipped flame.
The pilots are near the front of the burners, and are held in position by brackets. To adjust a pilot flame, 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 flame, or clockwise to decrease the size of the pilot flame. The maximum
flame size is approximately 3/4" with a slight yellow tip. The first indication of over-adjustment is when the flame tip becomes
more yellow and begins to generate carbon, which appears as rising black streaks. Continued over-adjustment leads to the
unstable lifting and a blowing condition.
