Outside Combustion Air Controls

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 outside air control 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 securing screw from the combustion air control lever located on the right side of the fireplace opening.

If the securing screw has not been 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.

WARNING

Do not operate the shutoff lever unless a complete outside com- bustion air system has been installed with your appliance.

To open the outside air shutter, open the bottom control access panel, and pull the outside air control lever all the way out. The outside air shutter should be fully open when the fireplace is in use and completely closed when the fire- place is not being used. Closing it when not in use will prevent outside cold air from entering the dwelling.

The hand operated outside air control lever is located on the right side of the fireplace open- ing. See Figure 5.

To open the outside air , open the bottom control access panel, reach into the gap between the firebox bottom and pull the outside air control lever all the way out.

The outside air shutter should be fully open when the fireplace is in use and completely closed when the fireplace is not being used. Closing it when not in use will prevent outside cold air from entering the dwelling.

Operate the actuator through several cycles including the closed position. Ensuring proper operation and freedom of movement. Return the actuator arm to the closed position.

WARNING

Turn off gas and electrical power before servicing the appliance.

CAUTION

Wear gloves and safety Glasses for protection while doing required maintenance.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Inspect Venting System

The appliance and venting system should be thoroughly inspected before initial use and at least annually by a qualified service technician (inspection should include ensuring that exhaust or intake passages are unobstructed and vent components are properly assembled and not dam- aged). If the venting system is disassembled for any reason, a qualified service technician should follow vent installation instructions for proper reassembly and proper sealing of the venting system components. However, more frequent periodic inspections and cleanings should be performed by the homeowner.

Clean Lower Control Compartment

Keep lower control compartment clean by vacu- uming or brushing it out at least twice a year (also clean the air venturi with a brush or wire). More frequentcleaningmayberequiredduetoaccumula- tion of lint from carpeting, bedding materials, pet hair, spider webs, etc. It is very important that control compartments, burners, circulating air passageways and air venturi on the appliance are NOT obstructed in any way.

Cleaning Glass

(see Front Glass Enclosure Panel, Removal and Installation on Page 9 ) Note: Clean glass after first two weeks of operation (after Burn-In period is over) and then only when necessary and when the fireplace is cool. Wipe surface with clean, dampened, soft cloth. Follow with dry, soft towel as desired. Take care not to scratch the glass surface.

The viewing glass should be cleaned periodically to remove any build-up caused from the fol- lowing:

IMPORTANT

Do not use abrasive cleaners on glass. Never clean glass when hot.

During start-up, it is normal for condensation to form on the inside of the glass (this condensation and fog will usually disappear in a few minutes). The moisture can cause lint, dust and other air- borne particles to cling to the glass surface.

Initial curing of the high temperature paint and burningoffoflubricantsusedinthemanufacturing process may result in a film on the glass.

A white coating may form on the glass as a result of impurities and minerals in the fuel.

It is recommended that the glass be cleaned two or three times during each heating season, depending on the circumstances present.

The following cleaning solutions are approved for use to clean glass:

Non-ammonia based household cleaner

50%-50% mix of white vinegar & water

gas fireplace/stove glass cleaner

Inspect Glass Gasket - Visually inspect the gasket on the backside of the glass enclosure panels. The gasket surface must be clean, free of irregularities and seated firmly.
