Page 16: Ash Removal
Soot and Fly-ash: Formation and Need for Removal Figure 5.2 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, such as, during startup, shutdown, or incorrect operation of the furnace will lead to some soot formation which will collect in the exhaust venting system. The exhaust venting system should be inspected at least twice monthly to determine if cleaning is necessary. Figure 5.3 Harman® • PF-120 Owner’s Manual_R3 • 2014 -___ • 10/14 3-90-08120c... -
