Adjustment of Graduated Hot-Top Pilot and Burner
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 pilot is beside the burner, and is held in position by a bracket. To adjust the pilot flame, insert a screwdriver through the
opening in the valve panel beside the control knob and turn the 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.
