Operating Instructions
For Your Safety, Read Safety Precautions
And Lighting Instructions Before Operating
The ideal ame will be blue at the base and light orange above. The ames should be of medium height.
If the ames look like this (refer to Figure Figure 43 or Front Cover), no adjustment is needed. If the
ames are fairly short and mostly blue, the replace is getting too much air. Therefore, the air shutter
should be closed slightly until the correct ames are achieved. Flames that are very orange, with tall,
dark, stringy tips, are not getting enough air. Open the air shutter until the ames clean up. If the shutter
is opened, or closed all the way, and the correct ames cannot be attained, turn off the gas and contact
the dealer.
Warning: Incorrect air shutter adjustment may lead to improper combustion, which is a safety hazard.
Contact the dealer if there is any concern about the venturi adjustment.
