9.3.2 SOOT ANd FLY ASh FORmATION The products of combustion will contain small particles of fly ash. The fly ash will collect in the exhaust venting system and restrict the flow of the flue gases. Incomplete combustion occurs during startup, shutdown, or incorrect operation of the room heater will lead to some soot formation which will collect in the exhaust venting system.
9.3.6 ChECk ALL SEALS Check for air leaks around the door, glass, and ash pan and replace gaskets as required. Air leaks into the firebox will decrease the heater's performance greatly, leading to excessive soot, inefficient burning, and may even cause a malfunction. Test the door seal by shutting the door on a piece of paper in various locations.
