CAUTION: You must keep control areas, burners, and circulating air passageways of fireplace clean. In- spect these areas of fireplace before each use. Have fireplace inspected yearly by a qualified service person. Fireplacemayneedmorefrequentcleaningduetoexces- sive 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 fireplacewiththeglassdoorremoved,cracked,orbroken.

WARNING: Do not use abrasive cleaners as this may damage glass. Use a nonabrasive household 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. Thereafter, clean the glass two or three times during each heating season, depending on the usage and circumstances present. Refer to Removing/Replacing Glass Door, pages 22 and 23 of this manual when removing glass door for cleaning.

WARNING: Only parts supplied by the manufac- turer should be used when replacing broken or dam- aged glass door panel (see Replacement Parts, page 36). 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 children and pets away from glass.

If glass has been broken, carefully remove glass door (see Remov- ing/Replacing Glass Door, pages 22 and 23). Vacuum all glass pieces with a shop vac.

CAUTION: Do not vacuum if pieces are hot.

Use only the tempered glass door replacement intended for this fireplace (see Replacement Parts, page 36 for detail on ordering). No substitutions may be made. See Removing/Replacing Glass Door, pages 22 and 23 for instructions for replacing glass door.

WARNING: Do not operate fireplace with the glass door removed, 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 24, to properly replace logs.

•Use a vacuum cleaner to remove any carbon buildup on logs.

•Replace log(s) if broken. See Replacement Parts on page 36.

•Replace ember material periodically as needed. See Replace- ment Parts on page 36.

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 immediately by a qualified service person.

2.Remove the vent cap and shine a flashlight into the vent. Re- move any foreign material.

3.Check for evidence of excessive condensation. 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 being exposed to cold weather.

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