Adjustments
Warning: Adjustments and service work may only be performed by a qualified
technician who is experienced in, and knowledgeable with, the operation of
commercial cooking equipment. However, to assure your confidence, contact
your authorized service agency for reliable service, dependable advice and other
assistance, and of genuine factory parts.
In case of problems in operation at initial installation, check type of gas and manifold pressure and compare
information listed on the serial plate.
ALL TOP BURNERS
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.
OVEN BURNER FLAME
The oven burner orifice is of the fixed type, sized for the specified gas supply. The burner flame
characteristics are controlled 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.
OVEN LOW FLAME LEVEL SETTING
When the oven reaches the temperature at which the dial is set, the oven thermostat reduces the flow of gas
to the amount required to keep the oven at that temperature. However, the thermostat must always supply
enough gas to keep the entire burner lighted. To maintain this minimum flame, the low flame setting must be
set carefully and accurately using the following procedure:
1. Turn on the oven and set the oven thermostat to 200°C.
2. When the oven reaches this temperature, the flame will reduce to the low flame setting.
3. Open the kick panel and look through the pilot hole to see if the flame is even and minimal along the entire
length of the burner. Also open and close the oven door to ensure the low flame does not extinguish. If the
flame is even and minimal and the flame does not extinguish then, the low flame setting level does not need
adjustment. If the flame extinguishes, then continue with this procedure to adjust the low flame setting.
4. Remove the control knobs, thermostat dial (using an allen key to loosen a screw on the side) and the front
panel.
5. Using a screwdriver, turn the low flame setting adjustor on the stem of the thermostat counterclockwise to
increase the flame or clockwise to decrease the flame until the flame is even and minimal along the entire
length of the burner.
6. Replace the front panel, control knobs, and thermostat dial. Turn all control knobs to the OFF position.
