Outside Combustion Air Controls
Appliances may be installed with an outside
(make-up air) vent system that is designed to
provide the appliance with outside make-up
air for combustion when in operation. The
shut-off lever for the outside air system is
standard on all appliances but should not be
operated if the complete system is not installed. Refer to
Figure 6
for GHC/GRD-5500
series units.
The hand operated shut-off lever is located in the
left side of the fireplace opening behind the
screen. To open, pull all the way. The outside air
damper should be fully open when the fireplace
is in use and completely closed when the fireplace is not being used. This will prevent outside
cold air from entering the dwelling.

Maintenance
The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service technician. Proper maintenance and use will require
more frequent, less extensive inspections and
servicing by the homeowner.
Generally, annual inspections should be performed by a qualified service technician. More
frequent periodic inspections and cleanings
should be performed by the homeowner. Any
discrepancies discovered by the homeowner
should result in a call to a qualified service
technician to effect the repair or correction.
Refer to the maintenance schedule for maintenance tasks, procedures, periodicity and by
whom they should be performed.
IMPORTANT: TURN OFF GAS AND ANY ELECTRICAL POWER BEFORE SERVICING THE
APPLIANCE.

MANUALLY-RESET BLOCKED FLUE SAFETY
SWITCH
This appliance is equipped with a manuallyreset blocked flue safety switch. Refer to
Figure 7
for its location. If during appliance
operation, the flame goes out (independently
of the burner on/off wall switch), it may be due
to the operation of this safety limit switch.
First allow the appliance to cool. Then reset
the safety switch by pushing the red reset
button on the back of the switch.
CAUTION: THE ELECTRONIC APPLIANCE
SHOULD BE TURNED OFF BEFORE REMOVING THE LIMIT SWITCH.
To access the safety limit switch reset button,
remove the two screws. Pull out limit switch
with low voltage wires attached, push the reset
button, then reinstall the limit switch. At this
time turn the electronic appliance back on.
The appliance should then relight and remain
lit. If this does not occur, turn off the appli-
ance and call a qualified service technician.
Burner Adjustments
Flame Appearance and Sooting
If the air shutter opening is too small sooting
may develop. 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 log set if the flames impinge on any of
them.
If sooting conditions exist, the air shutter
opening on the main burner can 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.
Adjustment
To adjust the flame, position the air shutter to
the nominal setting
(Figure 8 ).
Allow the
burner to operate for at least 30 minutes.
Observe the flame continuously. If it appears
weak or sooty as previously described, adjust
the air shutter open or closed until desired
effect is achieved.

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, or
with long vertical vent runs, will exhibit flames
that are blue and transparent. These weak, blue
and transparent flames are termed anemic.
