Ash Removal
disposal of ashes
Ashes should be placed in a steel container with a tight fitting
lid. The closed container of ashes should be moved outdoors
immediately and placed on a non-combustible floor or on the
ground, well away from all combustible materials, pending
final disposal. If ashes are disposed of by burial in soil or
otherwise locally dispersed, they should be retained in the
closed container until all cinders have thoroughly cooled.
Other waste shall not be placed in this container.
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 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. Pay particular
attention to screening in the vent cap. The screen, if present,
will accumulate with ashes rather quickly.
