Lennox Hearth LBV-4324EP, LBV-3824EN manual Maintenance, MANUALLY-RESET Blocked Flue Safety Switch

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 Figure 5. When the 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 pres- ence 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 fire- place 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.

MANUALLY-RESET BLOCKED FLUE SAFETY SWITCH

This appliance is equipped with a manually- reset blocked flue safety switch. Refer to Figure 6 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.

This reset button is located on the back of the limit switch, between the wire terminals (see Detail A of Figure 21 ).

The appliance should then relight and remain lit. If this does not occur, turn off the appli- ance and call a qualified service technician.

Maintenance

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- formed 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 mainte- nance tasks, procedures, periodicity and by whom they should be performed.

IMPORTANT: TURN OFF GAS AND ANY ELEC- TRICAL POWER BEFORE SERVICING THE APPLIANCE.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

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.

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 form- ing on the logs, appliance inside surfaces and on exterior surfaces adjacent to the vent termi- nation. Sooting is caused by incomplete com- bustion 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. Reposi- tion 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.
