The ideal flame will be blue at the base and light orange above. The flames should be of medium height.
If the flames look like this (refer to Figure Figure 43 or Front Cover), no adjustment is needed. If the
flames are fairly short and mostly blue, the fireplace is getting too much air. Therefore, the air shutter
should be closed slightly until the correct flames are achieved. Flames that are very orange, with tall,
dark, stringy tips, are not getting enough air. Open the air shutter until the flames clean up. If the shutter
is opened, or closed all the way, and the correct flames 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.
