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).

HUTTER
:
The air shutter adjustment lever is above the left side of the control valve (see Figure 4).
The air shutter allows the amount of air coming into the fireplace to be adjusted in order to accommodate
different altitudes 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 56.
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 (moved right)
slightly until the correct flames are achieved.
Flames that are very orange, with tall, dark,
stringy tips, are not getting enough air. Open
(move left) 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 your dealer.
Warning: Incorrect venturi adjustment may
lead to improper combustion, which could be a
safety hazard. Contact your dealer if there is any
concern about the venturi adjustment.

IGHT
:
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.

LOWER SPEED
:
The blower will come on only when the fireplace is up to temperature (approximately 20 minutes). The
speed of the fan can be changed by turning the fan control knob. To turn the blower off, turn the knob
COUNTER CLOCKWISE until it “clicks” off (Figure 5).
It is advisable not to operate the blower below

speed as it puts a strain on the windings of the blower
and running the blower at lower speeds could also cause premature fan failure.
