A qualified agency should examine the venting system annually.
CLEaNING GLaSS
Clean the tempered glass periodically. Condensation will some-
times form on the glass during a cold startup. This is normal for all
gas fireplaces. This condensation often attracts dust and lint to the
surface of the glass. The initial paint curing of the appliance can also leave a slight film on the
glass.
Your should clean the glass after the first two weeks of use. After that, you should clean the
glass no more than two or three times a season. Use a mild glass cleaner to clean the door. Do
not use abrasive cleaners. They will damage the glass surface.
