A DJUSTMENT OF O PEN- T OP B URNERS
All open-top burners are primarily adjusted by means of an air shutter on the mixer face.
To adjust a burner, loosen the screw that holds the air shutter in position and rotate the mixer cap until a clear, stable blue
flame is obtained. The flame should not be yellow tipped nor should it blow off the burner ports.
All orifice sizes and burner rate are properly set at the factory and should not be altered.
Over-rated burners cause poor burner and pilot performance, resulting in less heat, and wasted gas.
A DJUSTMENT OF G AS O VEN S TANDING P ILOT
The standing oven pilot flame can be adjusted by turning the adjusting screw on the pilot line valve with a screwdriver.
The pilot line valve is located behind the kick panel below the oven door. Remove the kick panel to gain access. The pilot
flame is properly adjusted when it is just large enough to maintain a glowing red color of the thermopile capillary bulb.
A DJUSTMENT OF G AS OVEN B URNER
The oven burner orifice is of the fixed type, sized for the specified gas supply. The burner flame characteristics are con-
trolled by varying the primary air mixer cap. There should be a clear blue flame with a distinct inner cone at each port.
Excessive primary air can result in “blowing” or the flames leaving the ports. Lack of primary air causes soft or yellow
tipped flame.

T OP B URNERS AND P ILOTS
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 screw-
driver 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 maxi-
mum 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 unstable lifting and a blowing condition.
C ALIBRATION OF G AS O VEN T HERMOSTAT
The oven thermostat control is carefully calibrated at the factory so that its dial settings closely match actual oven tem-
peratures. Field recalibration is seldom necessary, and should not be resorted to unless considerable experience with
unexpected cooking results definitely proves that the control is not maintaining the temperatures to which the dial is set.
When checking the oven temperature, use a test instrument or a reliable mercury thermometer positioned in the center of
the oven. The oven bottom must be in place. For convection ovens, the blower baffle must be in place.
Proceed as follows:
1. Light the oven pilot, set the oven thermostat to 350°F, and, if the oven is a convection oven, turn on the fan.
2. After burner has been on about 15 minutes, check the oven temperature. The oven door should be open for as short a
time as possible. Use a flashlight, if necessary, to see the thermometer clearly.
3. Continue to check temperature noting the minimum and maximum “swing” variation in temperature until two successive
readings are within 5 degrees of each other. The oven temperature is the midpoint of the “swing” range.
