emit a slight odor for an hour or two. This is
due to the “burn-in” of internal paints and
lubricants used in the manufacturing process.
3. Keep lower control compartment clean by
vacuuming or brushing at least twice a year.
More frequent cleaning may be required due to
excessive lint from carpeting, bedding materials, etc. It is important that control compartments, burners and circulating air passageways of the appliance be kept clean and clear of
obstructions of venting and combustion air.
4. Always turn off gas to the pilot (millivolt
appliances) before cleaning. Before re-lighting, refer to the lighting instructions in this
manual. Instructions are also found on a pullout panel located on the floor of the appliance.
5. Always keep the appliance area clear and
free from combustible materials, gasoline and

Maintenance
The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service technician. However, more frequent periodic inspections and cleanings should be performed by
the homeowner. Homeowner must contact a
qualified service technician at once if any
abnormal condition is observed.
These are direct-vent appliances. They are
designed to operate only with the front glass
enclosure panel properly installed. Generally,
the glass enclosure panel should not be removed except to gain access to the components within the firebox, and the appliance
may only be operated without the front glass
enclosure panel in place for very brief periods
of time during initial appliance checkout and
adjustment.
4. Swing the bottom of the door out and raise
it slightly to lift the top flange of the door frame
away from the appliance.

Refer to the maintenance schedule for maintenance tasks, procedures, periodicity and by whom
they should be performed. Always verify proper
operation of the appliance after servicing.
IMPORTANT: TURN OFF GAS AND ANY
ELECTRICAL POWER BEFORE SERVICING
THE APPLIANCE.
Glass Cleaning
It will be necessary to clean the glass periodically. During start-up it is normal for condensation to form on the inside of the glass. This
can cause lint, dust and other airborne particles to cling to the glass surface. Also initial
paint curing may deposit a slight film on the
glass. It is therefore recommended that the
glass be cleaned two or three times with a nonammonia household cleaner and warm water
(a gas fireplace glass cleaner is recommended).
After that the glass should be cleaned two or
three times during each heating season, depending on the circumstances present.
Note: Clean glass after first two weeks of
operation.
WARNING: DO NOT USE ABRASIVE
CLEANERS. NEVER CLEAN THE GLASS
WHEN IT IS HOT.

Burner Adjustments
The following paragraphs address burner adjustment concerns and procedures.
Flame Appearance and Sooting
Proper flame appearance is a matter of taste.
Generally most people prefer the warm glow of
a yellow to orange flame. Appliances operated
with air shutter openings that are too large will
exhibit flames that are blue and transparent.
These weak, blue and transparent flames are
termed anemic. If the air shutter opening is too
small sooting may develop.
6
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Sooting is indicated by black puffs developing
at the tips of very long orange flames. Sooting
results in black deposits forming on the logs,
appliance inside surfaces and on exterior surfaces adjacent to the vent termination.
Sooting is caused by incomplete combustion in
the flames and a lack of combustion air entering
the air shutter opening. To achieve a warm
yellow to orange flame with an orange body that
does not soot, the shutter opening must be
adjusted between these two extremes. No smoke
or soot should be present. Reposition the logs if
the flames impinge on any of them.
If the logs are properly positioned and sooting
conditions exist, the air shutter opening on the
main burner tube should be adjusted. Normally,
the more offsets in the vent system, the greater
the need for the air shutter to be opened further.
WARNING: AIR SHUTTER ADJUSTMENT SHOULD ONLY BE PERFORMED
BY A QUALIFIED PROFESSIONAL SERVICE TECHNICIAN.
ENSURE THAT THE FRONT GLASS PANEL IS IN
PLACE AND SEALED DURING ADJUSTMENT.
Adjustment
CAUTION: THE ADJUSTMENT ROD AND
NEARBY APPLIANCE SURFACES ARE HOT.
EXERCISE CAUTION TO AVOID INJURY WHILE
ADJUSTING FLAME APPEARANCE.
To adjust the flame, move the adjustment rod
(located in the lower control area) up or down
to increase or reduce the air shutter opening,
respectively. Initially, always position the air
shutter to the factory setting (the minimum
air opening position) as shown in
This can be done by pulling the adjustment
rod all the way down. Allow the burner to
operate for at least 15 minutes. Observe the
flame continuously. If it appears weak or sooty
as previously described, adjust the air shutter
by pushing or pulling on the adjustment rod
until the flame appearance is as desired.
The adjustment rod and associated adjustable
air shutter is patented technology. Flame adjustments can be made quickly and accurately
to taste without the need of disassembling the
appliance and waiting for 30 minutes after
each adjustment.
Figure 6
Propane models may exhibit a flame pattern
that may candle or appear stringy. If this is
problematic or persists as the appliance is
continually operated, adjust the air shutter
closed as described in the previous paragraphs. Operate the appliance for a period of
time as the effect diminishes, ensuring that the
appliance does not develop sooty flames.
When satisfied that the appliance operates
properly, proceed to finish the installation.
Leave the control knob in “ON” position and
turn the remote switch “OFF.” Close the lower
control compartment door.
