Avoiding Smoke and Odors
Negative Pressure and Electrical Power Failure:
Toreducetheprobabilityofback-draftingorburnbackinthe
applianceduringpowerfailureconditions,theappliancemust
beabletodraftnaturally,withoutoperationofthecombustion
blower.Negativepressureinthehousemayresistthisnatural
draftifnotaccountedforduringthepelletstove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.
Hearth & Home Technologies recommends the use of
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backdraftingofthis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
toward the prevailing wind direction, during the heating
season.
Theoutsideairconnectionwillsupplyallofthedemandsof
theappliance.However,considerationmustbegiventothe
totalhousedemand.Housedemandmayconsumetheair
neededforthestove.Itmaybenecessarytoaddadditional
ventilationtothespacein which the applianceislocated.
ConsultwithyourlocalHVACprofessionaltodeterminethe
ventilationdemandsforyourhouse.
Venting Congurations
Toreducethepossibilityofreversedraftingduringapower
failure,Hearth&HomeTechnologiesstronglyrecommends:
• Installingtheventpipewithaminimumverticalriseofve
feet,preferablyterminatingabovetheroofline.
• Installing outside air with the intake located below the
exhausttermination.
Topreventsootdamagetoexteriorwallsofthehouse,and
topreventre-entryofsmoke,soot,orashintothehouse:
• Maintain specied clearances to windows, doors, and
otherairinlets,includingairconditioners.
• Vents should not be placed below ventilated soffits.
Wheneverpossible,runtheventingabovetheroofline.
• Avoidterminatingtheventinanalcovelocation.
• Ventsshouldnotterminateunderoverhangs,decksor
ontocoveredporches.
• Maintain a minimum clearance of 12" 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.
Optional Battery Back-Up
Hearth&HomeTechnologiessuppliesanoptionalbattery
backupsystemtooperate the appliance during alossof
electrical power. Whether you experience frequent power
failuresornot,thisbackupsystemisrecommended.
Hearth & Home Technologies assumes no responsibility
for, nor does the warranty extend to, smoke damage
caused by reverse drafting of appliances during a power
failure condition.
