1. Turn off the gas to the fireplace. If not recently done, remove the glass and let the unit air
out for at least five (5) minutes to clear out any gas. Turn on gas to the heater. Leak test all joints
with soapy water. NEVER USE OPEN FLAME FOR LEAK TESTING.

The air shutter is controlled with the primary air adjustment rod located behind the gas valve shown in
Figure 5.
The air shutter allows the amount of air coming into the fireplace to be adjusted in order to accommodate
different climates and venting arrangements. Start 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
fifteen minutes and then examine the flames, compare the flames to Figure 55.

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 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 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.
