Air Band Adjustment
Note: The air band adjustment on this burner has been preset at the factor (elevation approximately 1400
feet). On equipment installed where elevation is substantially different, the air band(s) must be readjusted.
1. Loosen the cap screw retaining the air bands.
2. Move the air bands as indicated below with the machine in operation. Note: The air band should
be set so the exhaust gives the smoke spot specied in the GENERAL section of the MACHINE
SPECIFICATIONS on a Shell-Bacharach scale. If a smoke tester is not available, a smoky
exhaust, oily odor, or sweet smell indicates insufcient air while eye-burning fumes indicate too
much air.
3. Tighten the cap screw retaining the air bands.
