a millivolt or electronic appliance. Millivolt  
appliances will be fitted with the gas control  
valve shown in Figure 3. Appliances with  
electronic systems will be fitted with the elec-  
tronic valve shown in Figure 4. Familiarize  
yourself with the differing controls for the  
valve your appliance uses.  
2. 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 ma-  
terials, etc. It is important that control com-  
partments, burners and circulating air pas-  
sageways of the appliance be kept clean.  
Figure 5  
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 in-  
stalled. Refer to Figure 6 for GHC/GRD-5500  
series units.  
3. Always turn off gas to the pilot (millivolt  
appliances)beforecleaning. Beforere-lighting,  
refer to the lighting instructions in this manual.

found on the pull-out label located near the  
gas valve in the control compartment.  
Millivolt Appliance Lighting  
To light millivolt appliances refer to the de-  
tailed lighting instructions found in both En-  
glish and French on pages 10 and 11 of these  
instructions respectively. Appliance lighting  
instructions may also be found on the pull-  
out label located near the gas valve in the  
control compartment. Refer to Figure 1 for  
the piezo ignitor location used with your  
appliance.  
4. Always keep the appliance area clear and  
free from combustible materials, gasoline and  
other flammable liquids.  
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 fire-  
place is not being used. This will prevent outside  
cold air from entering the dwelling.

tinuous burning pilot flame. Exercise caution  
when using products with combustible vapors.  
6. Clean the optional glass doors only when  
necessary. Wipe surface with clean, damp-  
ened, soft cloth. Follow with dry, soft towel as  
desired. Take care not to scratch the glass  
surface.

Maintenance  
Manual Reset Limit Switch  
The appliance and venting system should be  
thoroughly inspected before initial use and at  
least annually by a qualified service techni-  
cian. Proper maintenance and use will require  
more frequent, less extensive inspections and  
servicing by the homeowner.  
Generally, annual inspections should be per-  
formedbyaqualifiedservicetechnician. 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.

Adjustment  
If the air shutter opening is too small sooting  
may develop. Sooting is indicated by black  
puffsdevelopingatthetipsofverylongorange  
flames. Sootingresultsinblackdepositsform-  
ing on the logs, appliance inside surfaces and  
onexteriorsurfacesadjacenttotheventtermi-  
nation. Sooting is caused by incomplete com-  
bustion in the flames and a lack of combustion  
air entering the air shutter opening.  
MANUALLY-RESET BLOCKED FLUE SAFETY  
SWITCH  
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.  
This appliance is equipped with a manually-  
reset 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.  
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.

CAUTION: THE ELECTRONIC APPLIANCE  
SHOULD BE TURNED OFF BEFORE REMOV-  
ING THE LIMIT SWITCH.

No smoke or soot should be present. Reposi-  
tion the log set if the flames impinge on any of  
them.  
Adjusting  
Set Screw  
To access the safety limit switch reset button,  
remove the two screws. Pull out limit switch  
withlowvoltagewiresattached, pushthereset  
button, then reinstall the limit switch. At this  
time turn the electronic appliance back on.  
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.  
Burner Tube  
The appliance should then relight and remain  
lit. If this does not occur, turn off the appli-  
ance and call a qualified service technician.  
Nominal Air Shutter Settings:

Figure 8  
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, or  
with long vertical vent runs, will exhibit flames  
that are blue and transparent. These weak, blue  
and transparent flames are termed anemic.

The gas control system on these appliances is  
a millivolt standing pilot type. It consists of a  
pilot burner, a piezo ignitor, a gas control valve,  
a burner assembly and an ON/OFF wall switch.  
A temperature limit switch is wired in series  
with the millivolt wall switch and gas control  
valve. If a higher than normal temperature is  
sensed due to a blocked vent or prolonged  
downdraft, the limit switch will open and cause  
the burner to shut off.  
1. Remove the pilot adjustment cap located on  
the main gas valve.  
2. Adjust the pilot screw to provide properly  
sized pilot flame (Figure 10 ). Turn counter  
clockwise to enlarge pilot flame and clockwise  
to reduce the pilot flame. DO NOT attempt to  
adjust pilot flame more than one half turn.  
3. Replace the pilot adjustment cap.  
The logs are packaged within the firebox.  
The bag of rockwool is in the lower control  
compartment. Remove the rockwool from  
the packaging and tear into dime size pieces  
(Figure 9). Spread across the burner in front  
of the front log. See Figure 10. Do not use  
more than is necessary to cover the burner.  
When properly positioned, the rockwool will  
unevenly cover approximately 85% of the  
front of the burner with no appreciable gaps.  
The pilot flame should be steady, not lifting or  
floating. Flame should be blue in color with  
traces of orange at the outer edge.  
Replace logs if removed for pilot inspection.  
To light the burner; rotate the gas valve control  
knobcounterclockwisetotheONpositionand  
then turn ONthe remote wall switch.  
The top ³⁄₈" (9 mm) at the pilot generator  
(thermopile) should be engulfed in the pilot  
flame (Figure 11).  
Electronic Appliance Checkout  
The gas control system on these appliances is  
an electronic low voltage gas control valve with  
an intermittent ignitor. It consists of a low  
voltage gas control valve, an intermittent igni-  
tionsystem,anelectroniccontrolmodule,trans-  
former and a burner assembly. A temperature  
limit switch is wired in series with the gas  
control valve. If a higher than normal tempera-  
ture is sensed, due to a blocked vent or pro-  
longed downdraft, the limit switch will open  
and cause the burner to shut off.
