3. Figure 21 Glass Doors 12 www desatech com 111099 01C OPERATION AND MAINTENANCE GUIDELINES Continued A fireplace equipped with glass doors operates mush differently than a fireplace with an open front A fireplace with glass doors has a limited amount of air for combustion Excessive heat within the fireplace can result if too large a fire is built or if the combustion air gate is not com pletely open The following tips should be followed to assure that both the fireplace and the glass door retain their beauty and function properly Both the flue damper and the glass doors must be fully opened before starting the fire This will provide sufficient combustion air and maintain safe temperatures in the firebox IMPORTANT The glass must be allowed to warm slowly and evenly The tempered glass will withstand a gradual temperature rise to 550 F which is more than a normal fire will generate Such materials as pitch wax laden logs very dry mill end lumber and large amounts of paper or cardboard boxes can create an excessively hot fire and should not be burned in this fireplace Always keep the fire well back from the doors and never allow flames to contact the glass d WARNING Fireplaces equipped with glass doors should be operated only with doors fully opened or doors fully closed Doors ifleft partly open may draw gas and flame out of the fireplace opening creating risks of both fire and smoke Cleanin
