Before adjusting the air shutter, verify that the correct orifice size for the gas type specified
ADJUSTING THE REAR BURNER FLAME
Each oven burner is tested and adjusted at the factory prior to shipment; however, variations in
the local gas supply may make it necessary to adjust the rear burner. The amount of air is controlled
by a sheet metal cup at the inlet of the burner called an air shutter. It is locked in place by a screw
which must be loosened prior to lighting the burner for adjustment. The air shutter's adjustment screw
is adjustable with a Phillips screwdriver. Loosen the lock screw for adjustments and tighten when ad-
justments of the air shutter are complete. Adjust according to the following directions. Be careful as
the burner and other grill parts may be very hot!
•
If the flame is noisy and tends to lift away from the burner, indicating too much air, very gently
close the air shutter.
•
If the flame is lazy or wavy, indicating not enough air, very gently open the air shutter.
Remember to tighten the adjustment screw prior to re-installing the access panel.
ENSURE THAT THE BURNER IS SITTING PROPERLY ON THE ORIFICE PRIOR TO LIGHTING.
Access to the Rear Burner air shutter and internal flex tubing can be found through the rear
access panel located at the back right corner of the Pizza Oven. See pictures below:
