Adjustment of 33K and 45K Open-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 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 approximate-
ly 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 unstable lifting
and a blowing condition.
