Soot and Fly Ash
The products of combustion will contain small par-
ticles 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 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. The exhaust venting system
should be inspected after the first month of burning to
determine the frequency of cleaning that will be required.
NOTE: The frequency could vary from once a month
to once a season depending on the quality of the fuel
being used.
