Chimney/Vent System Cleaning: 1. Soot Formation – When wood products are burned slowly they produce tar and other organic vapors which combine with expelled moisture to form soot. The soot vapors condense in the relatively cool chimney flue, as a result soot residue accumulates on the chimney lining. When ignited soot makes an extremely hot fire which can damage the chimney or cause a house fire. If a soot/creosote fire occurs, shut down the heater immediately and call the fire department. 2. Soot and Flyash: Formation and Need for Removal—The products of combustion will contain small particles of flyash. The flyash will collect in the exhaust venting system and restrict the flow of the flue gases. Incomplete combustion, such as occurs during startup, shutdown, or incorrect operation of the room heater ...
See figure 26, page 31, for component locations The heater will not light: Check that the heater is plugged in and that the wall outlet has power. Unplug the unit then check all electrical connections against the Wiring Diagram in this manual. Check the fuse on the circuit board. If a thermostat is used, ensure it is calling for heat. If your heater still does not light contact your local dealer for service. The heater will not operate when hot. Check that the fuel hopper has enough pellets. Check that the combustion air inlet is not blocked. Insufficient air supply may cause the fire to burn cold and may cause fuel build up, in the pot, and smother the fire. Check that the exhaust fan is operating, if the fan is not operating properly it may not generate enough vacuum in the firebox. ...
