Requirements for Terminating the Venting
WARNING: Venting terminals must not be recessed into

NOTE: Only PL vent pipe wall pass-through and re
stops should be used when venting through combustible
materials.
NOTE: Always take into consideration the effect the
prevailing wind direction or other wind currents will
cause with flyash and /or smoke when placing the

H. 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
Anoutsideairkitisrecommendedinallinstallations.The
OutsideAirKitmustbeorderedseparately.
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roofvented(stronglyrecommended): 
Theairintakeisbestlocatedontheexteriorwalloriented
towardstheprevailingwinddirectionduringtheheating
season.
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.
Theoutsideairsupplykitcansupplymostofthedemands
ofthepelletappliance,butconsiderationmustbegivento
thetotalhousedemand.
House demand may consume the air needed for the
appliance.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.
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.

Pelletventingpipe(alsoknownasTypeLvent)isconstructedoftwolayerswithairspacebetweenthelayers.Thisairspace
actsasaninsulatorandreducestheoutsidesurfacetemperaturetoallowaclearancetocombustiblesofonly3inches.The
sectionsofpipelocktogethertoformanairtightsealinmostcases;however,insomecasesaperfectsealisnotachieved.
ForthisreasonandthefactthattheP43operateswithapositiveventpressure,wespecifythatthejointsalsobesealed
withsilicone.
