DIRECT-VENT FIREPLACE (NATURAL/PROPANE/LP)

CLEANING AND MAINTENANCE

WARNING: Turn off fireplace and let cool before cleaning.

CAUTION: You must keep con- trol areas, burners, and circulat- ing air passageways of fireplace clean. Inspect these areas of fire- place before each use. Have fire- place inspected yearly by a quali- fied service person. Fireplace may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.

GLASS DOOR

WARNING: Handle glass door panel with care. Do not strike, slam, or otherwise abuse glass. Do not operate fireplace with the glass door removed, cracked, or broken.

WARNING: Do not use abra- sive cleaners as this may damage glass. Use a nonabrasive house- hold glass cleaner to clean glass. Do not clean glass when hot.

Glass must be cleaned periodically. During start-up it is normal for condensation to form on the inside of the glass causing lint, dust, and other airborne particles to cling to the glass surface. During initial start-up a slight film may form on the glass due to paint curing. The glass should be cleaned several times with a non-ammonia, non- abrasive household cleaner and warm water after the first two weeks of operation. There- after, clean the glass two or three times during each heating season, depending on the usage and circumstances present. Refer to Removing/Replacing Glass Door on page 21 of this manual when removing glass door for cleaning.

WARNING: Only parts sup- plied by the manufacturer should be used when replacing broken or damaged glass door panel (see Replacement Parts, page 30). This glass door panel is a complete unit. No substitute materials may be used.

CAUTION: Wear gloves and safety glasses while handling or removing broken glass. Do not remove if glass is hot. Keep chil- dren and pets away from glass.

If glass has been broken, carefully remove glass door (see Removing/Replacing Glass Door, page 21). Vacuum all glass pieces with a shop vac.

CAUTION: Do not vacuum if pieces are hot.

Use only the glass door replacement in- tended for this fireplace (see Replacement Parts, page 30 for detail on ordering). No substitutions may be made. See Removing/ Replacing Glass Door, page 21 for instruc- tions for replacing glass door.

WARNING: Do not operate fireplace with the glass door re- moved, cracked, or broken.

PILOT AND BURNERS

Remove ember material before cleaning burners and replace when cleaning is complete.

Burner and controls should be cleaned with compressed air to remove dust, dirt, or lint.

Use a vacuum cleaner or small, soft bristled brush to remove excess dust, dirt, or lint.

LOGS

If you remove logs for cleaning, refer to Installing Logs, Lava Rock, and Glowing Embers, page 23, to properly replace logs.

Use a vacuum cleaner to remove any car- bon buildup on logs.

Replace log(s) if broken. See Replace- ment Parts on page 30.

Replace ember material periodically as needed. See Replacement Parts on page 30.

VENTING SYSTEM

Conduct annual inspection of the venting system following these guidelines:

1.Check areas of venting system that are exposed to the weather for corrosion (rust spots or streaks and, in extreme cases, holes). Have these items replaced imme- diately by a qualified service person.

2.Remove the vent cap and shine a flash- light into the vent. Remove any foreign material.

3.Check for evidence of excessive con- densation. Continuous condensation can cause corrosion of caps, pipes, and fittings and can be caused by having excessive lateral runs, too many elbows, or exterior portions of the system be- ing exposed to cold weather.

4.Inspect joints to verify that no pipe sec- tion or fitting has been disturbed and loosened. Check mechanical supports such as wall straps for rigidity.
