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.

WARNING: DO NOT OPERATE THE SHUTOFF LEVER UNLESS A COMPLETE OUTSIDE AIR VENT SYSTEM HAS BEEN INSTALLED WITH YOUR APPLIANCE.

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 appliance and call a qualified service technician.

Burner Adjustments

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.

Figure 7

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.
