2. Start the pilot by pressing the gas control knob and turning it to PILOT.
While holding the gas control knob in, press the piezo ignitor several times
until the pilot light starts. Hold the gas control knob in for 30 seconds.
Check that the pilot has fully engulfed the thermocouple assembly (see
Figure 3).
3. Start the main burner by turning the gas control knob to ON and then
turn the rocker switch to ON. Check that all burner ports have flame.
4. Leak test all gas joints again.

:
The air shutter adjustment lever is centered above the controls (see Figure 4).
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 40.
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 (push in) slightly until the correct
flames are achieved. Flames that are
very orange, with tall, dark, stringy tips,
are not getting enough air. Open (pull
out) 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.

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.
