To reduce probability of reverse drafting during a
power failure, Hearth & Home Technologies strongly
recommends:
• Installingthepelletventwithaminimumverticalriseof
vefeet.Preferablyterminatingabovetheroofline.
• Installinganoutsideairconnectiontotheappliance.
To prevent soot damage to exterior walls, and to prevent
re-entry of soot or ash into the home:
• Maintainspeciedclearancestowindows,doorsandair
inlets,includingairconditioners.
• Ventsshouldnotbeplacedbelowventilatedsofts.
• Avoidventingintoalcovelocations.
• Vents should not terminateunderoverhangs, decks or
ontocoveredporches.
• Maintain minimum clearance of 12” from the vent
terminationtotheexteriorwall.
Hearth & Home Technologies assumes no responsibility
for, nor does the warranty extend to, smoke damage
caused by reverse drafting of pellet appliances under
power failure conditions.
Hearth&HomeTechnologiesstronglyrecommendstheuse
ofoutsideairforallpelletfurnaceapplications.
Per national building codes, consideration must be given
to combustion air supply for all appliances in the vicinity
ofthepelletboiler.Failuretosupplyadequatecombustion
airforallappliancedemandsmaylead to backdrafting of
thoseappliances.ConsultwithyourHVACProfessionalto
determinethatallcombustionairrequirementsaremet.
When the appliance is side-wall vented:Theairintakeis
bestlocatedonthesameexteriorwallas,andlower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
