Air Shutter Adjustment
CAUTION: Air shutter is hot while the appliance is operating and
should only be adjusted using a heat resistant glove.
The air shutter control lever is located on the bottom of the stove directly
to the left of the gas valve. The lever is linked to the primary air shutter
on the main burner. The air shutter regulates the amount of primary air
the burner receives and, therefore, how clean the stove burns. The air
shutter should only be adjusted by a qualified gas technician. The stove
should burn for about 15 minutes with the logs installed before adjusting
the air shutter. Moving the lever to the left will open the shutter and turn
the flames more transparent and blue. Moving the lever to the right will
close the shutter and turn the flames more orange.
CAUTION: The air shutter should never be set so as to make the
tips of the flames sooty or create sooting on the viewing glass,
logs, or firebox ceiling. If soot begins to form after burning, the
air shutter should be opened gradually until the sooting condi-
tion stops. Gas quality and gas pressure may vary, which can
affect the burning characteristics of the stove.
Quiet Operation
As the appliance is burning, a number of normal operational sounds may
be heard. The flow of gas through the gas valve and orifice may make a
rushing or whistling noise. If this noise is objectionable, it can be reduced
by turning down the flame. Turning down the flame can reduce total heat
output by more than 30%. When the blower turns on, the sound of rush­
ing air may be heard. The blower sounds may be reduced by adjusting
the speed control located on the blower assembly. Also, a slight clicking
sound may be heard as the gas valve or blower switch is turned on and off.
Paint Curing
This stove has been painted with Stove Bright high temperature metallic
paint. It leaves the factory dry to the touch, but completes the curing
process as the stove is used. To cure the paint, burn the appliance four
successive times for ten minutes each time with a five minute cool down
between each firing. Also some parts of the appliance may be lightly
coated with machining oil. Ventilate the house during these first firings
as the paint and oil give off carbon dioxide and unpleasant odors. It is
recommended that persons sensitive to an imbalance in the indoor air
quality avoid the appliance during the curing process.
Optional Wall Thermostat
If an optional wall thermostat is to be installed, install the thermostat per
the manufacturers instructions (provided with the thermostat). Failure
to follow manufacturers instructions could result in a malfunction. Pay
special attention to the thermostat location requirements. If the location
requirements are not adhered to the appliance, erratic operation or failure
may occur.
Do not mount the thermostat where it may be affected by:
• Radiant heat from this appliance, fireplaces, sun or other heat
sources.
• Drafts or dead spots behind doors or in corners.
• Hot or cold air from ducts.
