DAMPER AND OUTSIDE AIR CONTROLS

This appliance is fitted with a manually controlled vent damper. The vent damper should be closed when the appliance is not in use to prevent cold air from entering the home through the venting system. The damper is controlled through the use of a control lever located within the appliance opening at the top center in front of the firebox lintel

(see Figure 5 )

. The control lever snaps into place at either extreme of its range of motion. When locked in position all the way to the right, the damper is open. When locked in position all the way to the left, the damper is closed.

The damper lever actuates a switch, (see wiring diagram) which will prevent the appliance main burner from lighting unless the damper is locked open. The appliance flue damper must always remain open when operating.

WARNING: DAMPER MUST BE IN OPEN POSITION WHEN APPLIANCE MAIN BURNER IS OPERATING.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Many appliances are equipped when 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 complete outside air vent system is installed, the installer will remove the cover from the shut-off lever located in the left side of the firebox opening.

If your cover is not removed and you have reason to believe that you have a complete outside air system, contact your distributor to have your appliance inspected for the presence of the complete system. DO NOT assume that you have this system in place.

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.

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.

Lintel Extension

Manual Reset Limit Switch

Right Side Refractory Panel

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.
