13. System Check
1. PURGING THE GAS LINE: When lighting the appliance
for the first time, it will take a few moments to clear the
gas line of air. Once this purge is complete, the appliance
will operate as described in the lighting instructions. From
a cold start, it may be helpful to let the pilot light burn in
mode for 10 - 15 minutes to establish positive draft, before
turning the burner on. See the procedure on the inside
back cover of this manual. Subsequent burner starts will
not require purging the gas line unless the supply line is
shut off.
2. PILOT FLAME: You can monitor the pilot flame located
behind the burner at the rear of the firebox. The pilot flame
should be steady - not lifting or floating. The flame should
be blue in color around the pilot hood, with traces of yellow
toward the outer edges. Fig. 13.1.
The pilot flame should engulf the top 1/8" of the
thermocouple and be fully engaged with the thermopile.
The pilot flame should project from the pilot hood port
toward the burner carry-over ports. Adjust the pilot
flame using the adjustment screw to the left of the valve
regulator. See fig. 13.2.
3. See Flame Appearance / Air Shutter for air shutter settings
and adjustments. Note: The more offsets there are in
the vent system, the greater the need for an air shutter
adjustment.
INITIAL FIRING PROCESS -
Heat-curing the Stove Paint
This appliance has been painted with the highest quality
coating used in the hearth industry. Manufacturers
have selected this product because it has been proven
durable, colorfast, and beautiful at temperatures up to
1200°F/650°C. Although the paint has been air-dried at
the factory, it must be heat-cured in order to maximize its
coating properties and durability. This process occurs during
initial firing of the appliance and will generate odor and
some visible smoke.
We recommend you do the following BEFORE operating the
appliance for the first time:
1. Ventilate: Open doors and windows and use a fan to
circulate fresh air throughout the room.
2. Vacate: The fumes are non-toxic, but can be
uncomfortable for babies, small children, pregnant
women, elderly, pets, or anyone having breathing
difficulties.

1. After the installer has confirmed proper burner function
at all heat levels, the homeowner should operate the
appliance at a low setting for several hours, followed by
several hours operation at a high setting.
2. Off-gassing by paint and log set ceramic material may
leave a white, powdery deposit on the inside surface of
the glass panel. This residue must be removed using a non-
abrasive hearth gas appliance glass cleaner or warm water
to prevent permanent etching of the glass.
DO NOT USE AMMONIA-BASED CLEANERS. DO
NOT CLEAN HOT GLASS.
See OPERATION sections, pages 25-30, for detailed, day-
to-day operating procedures.
