the pilot and then the burner. Make sure the pilot flame is burning normally and none of the burner ports
are plugged. Let the fireplace burn for roughly fifteen9minutes and then examine the flames, compare
the flames to Figure 16.
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, no venturi adjustment is needed. If the flames are fairly short and mostly blue,
the fireplace is getting too much air. Therefore, the venturies 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 venturi until the flames clean up. If the venturi is opened, or closed all the way, and the correct
flames cannot be attained, turn off the gas and contact the dealer.
Warning: Incorrect venturi adjustment may lead to improper combustion, which is a safety hazard.
Contact the dealer if there is any concern about the venturi adjustment.
