Ash Removal
Itisrecommendedtoremovetheasheswhenthefurnace
isnotinoperation.Thislessensthechancesofcomingin
contactwithhotsurfaces.Ashescanberemovedwhilein
operationbut,extracaremustbetaken.
Open Outer Ash Door
Liftthetwolatchesshowningure63andopentheouterdoor
asshowningure64.IftheDistributionBlowerisrunning
whentheouterdoorisopen,someairwillescapearound
thedooropening.Thisisnotaproblem,howeveranydust
thatiscausedintheashremovalprocesscanpotentiallybe
blownaround.
Open Inner Ash Door
Liftlatchesshowningure64andopentheinnerdooras
showningure65.
Remove Ash Pan
Alwayswearglovestoremoveashpan.Grabtheashpan
bythehandleandpullitoutofthefurnace.Liftthehandle
anduseitforcarryingtheashpan. Close the inner door
before disposing of the ashes.
Disposal of Ashes
Ashes should be placed in a metal container with a
tight fitting lid. The closed container of ashes should
be 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 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.
NOTE: Keep hopper lid and ash pan doors closed
during operation and maintain all seals in good
condition.
