Disposal of Ashes
Ashesshouldbeplacedinasteelcontainerwithatighttting
lid.Theclosedcontainerofashesshouldbemovedoutdoors
immediatelyandplacedonanon-combustibleoororonthe
ground,wellawayfromallcombustiblematerials,pending
nal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.

Soot and Flyash: Formation and Need for Removal
The products of combustion will contain small particles
of yash. The yash will collect in the exhaust venting
systemandrestrict theowofthe ue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.
