GLASS DOOR 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-amonia, nonabrasive 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 Dooron page 22 of this manual when removing glass door for cleaning. If glass has been broken, carefully remove glass door (see Removing/Replacing Glass Door, page 22). Vacuum all glass pieces with a shop vac. CAUTION: Do not vacuum if pieces are hot. Use only the ceramic glass door replacement intended for this fireplace (see Replacement Parts, page 32 for detail on ordering). No substitutions may be made. See Removing/Replacing Glass Door, page 22 for instructions for replacing glass door. WARNING: Do not operate fireplace with the glass door removed, cracked, or broken. , page 24, to properly replace logs. Replace on page 32. Replacement Parts on page 32. 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. Remove 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. 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 abrasive cleaners as this may damage glass. Use a non-abrasive household glass cleaner to clean glass. Do not clean glass when hot. 28 104605 OWNER’S MANUAL TROUBLESHOOTING Note: For additional help, visit DESA International’s technical service web site at Note: All troubleshooting items are listed in order of operation.
