ADJUSTMENTS

ADJUSTMENT OF OVEN PILOT AND BURNER

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 oven pilot ame is adjusted by using a screwdriver to turn the adjusting screw on the pilot line valve (see drawing

below). The pilot line valve is located behind the kick panel below the oven door. To gain access, lift the kick panel

straight up and pull the top edge out. The pilot ame is properly adjusted when it is just large enough to maintain a

glowing red color of the ame switch capillary bulb. The rst indication of over-adjustment is when the ame tip be-

comes yellow and begins to generate carbon, which appears as rising black streaks. Continued over-adjustment leads

to unstable lifting and a blowing condition
