28Maintenance - Cleaning Glass on View DoorThe unit should be out and cool to clean the door glass. It may not always be possible to allow the unit tocool off before cleaning. Therefore, if the unit is turned to the lowest setting about 1 hour before cleaning, it willmake it possible to clean the glass with the unit in operation.Any glass cleaner with a high amonia content will work the best. Use only non-synthetic cleaning ragssuch as cotton or paper towels.CAUTION: Take care when spraying cleaner on the inside surface of the glass. The glass may be hotenough to cause undesirable fumes to fill the area around the unit very rapidly. Gloves and eyeprotection are recommended.Disposal of ashes: Ashes should be placed in a metal container with a tight fitting lid. The closed container ofashes should be placed on a non-combustible floor or on the ground, well away from all combustible materials,pending final disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should beretained in the closed container until all cinders have thoroughly cooled.Soot and fly ash: Formation and need for removal. The products of combustion contain small particles of flyash. The fly ash will collect in the exhaust venting system and will restrict the flow of the flue gases. Pellet fuelshave different ash contents depending on what type of wood has been used to make the pellets. Werecommend to clean the system after approximately 1 ton of pellets have been burned and judge fromthat how often the stove should be cleaned, remember if you change pellets it may change how oftenyou have to clean your stove.Incomplete combustion such as occurs during start up, shutdown, or improper operation of the heaterwill lead to some soot formation, which will collect in the exhaust venting system. The exhaust vent should beinspected at least once every year to determine if cleaning is necessary.Glass GasketReplace glassonly with hight e m p e r a t u r eceramic glass.Inspect door gasket duringcleaning and inspectionFig. 57
