B. Avoiding Smoke and Odors
Negative Pressure, Shut-down, and Power
Failure:
To reduce the probability of back-drafting or burn-
back in the pellet burning appliance during power
failure or shut-down conditions, the stove must
be able to draft naturally without exhaust blower
operation.Negativepressureinthehousewillresistthis
naturaldraftifnotaccountedforinthepelletappliance
installation.
Heatrisesinthehouseandleaksoutatupperlevels.
Thisairmustbereplacedwithcoldairfromoutdoors,
whichowsintolowerlevelsofthehouse.Ventsand
chimneysintobasementsandlowerlevelsofthehouse
can become the conduit for air supply, and reverse
undertheseconditions.
Outside Air:
Hearth & Home Technologies recommend attaching
outside air in all installations, especially lower level
and main oor locations.
Pernationalbuildingcodes,considerationmustbegiven
tocombustionairsupplytoallcombustionappliances.
Failure to supply adequate combustion air for all
appliancedemands,mayleadtoback-draftingofthose
andotherappliances.
Whentheapplianceisside-wallvented:Theairintake
isbestlocatedonthesameexteriorwallastheexhaust
vent outlet and located lower on the wall than the
exhaustventoutlet.
When theappliance is roof vented:The air intakeis
bestlocatedontheexteriorwallorientedtowardsthe
prevailingwinddirectionduringtheheatingseason.
Theoutsideairconnectionwillsupplythedemandsof
thepelletappliance,butconsiderationmustbegivento
thetotalhousedemand.Housedemandmayconsume
someairneededforthestove,especiallyduringapower
failure.Itmaybenecessarytoaddadditionalventilation
tothespaceinwhichthepelletapplianceislocated.
ConsultwithyourlocalHVACprofessionaltodetermine
theventilationdemandsforyourhouse.
Theoutsideairkitconsistsofauestubpipe,berglass
gasket,siliconegasket,intakeboxandasectionofex
pipe.
Anadjustablechimneyintakeextension,part#1-00-
674104isavailabletobeusedonmasonrychimneys
only.
Toinstalloutsideair,usekitpartnumber1-00-774280.
Followtheinstallationinstructionsprovidedwiththekit.
Vent Congurations:
Toreduceprobabilityofreversedraftingduringshut-
downconditions,Hearth&HomeTechnologiesstrongly
recommends:
• Installingthepelletventwithaminimumverticalrun
ofvefeet,preferablyterminatingabovetheroofline.
• Installingtheoutsideairintakeatleastfourfeetbelow
theventtermination.
Topreventsootdamagetoexteriorwallsofthehouse
andtopreventre-entryofsootorashintothehouse:
• Maintain specied clearances to windows, doors,
andairinlets,includingairconditioners.
• Ventsshouldnotbeplacedbelowventilatedsofts.
Runtheventabovetheroof.
• Avoidventingintoalcovelocations.
• Ventsshouldnotterminateunderoverhangs,decks
orontocoveredporches.
• Maintain minimum clearance of 12 inches from
theventterminationtotheexteriorwall.Ifyousee
deposits developing on the wall, you may need
to extend this distance to accommodate your
installationconditions.
Hearth & Home Technologies assumes no
responsibility for, nor does the warranty extend
to, smoke damage caused by reverse drafting of
pellet appliances under shut-down or power failure
conditions.
Do not connect this unit to any air distribution
duct or system.
