Empty ashes and reinstall ash pan.
Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a noncombustible floor or on the ground, well awayfrom all combustible materials, pending final disposal. If ashes are disposed of by burial in soil or otherwise locallydispersed, theyshould be retained in the closed container until all cinders have thoroughly cooled.

Soot and Fly Ash
The products of combustion will contain small particles of fly ash. The fly ash will collect in the exhaust venting sys- tem and restrict the flow of the flue gases. Incomplete com- bustion, such as occurs during startup, shutdown, or incor- rect operation of the room heater, will lead to some soot for- mation which will collect in the exhaust venting system. The exhaust venting system should be inspected at least once each year to determine if cleaning is necessary.
When removing the ash pan to empty ashes, you will note a build up of ash fines behind the ash pan. This space behind the ash pan was designed to allow the fines to fall out of the vertical heat exchangers and collect where they are easily cleaned out, rather than going into the flue pipe where it would be difficult to clean. These fines should not be al- lowed to build up. They may not allow the ash pan to be seated into its gasket properly.NOTE: If an extreme amount of force is required to snap the latch on one or both sides of the ash pan, the area behind the ash pan should be checked for ash fine build up.
