Do not terminate ventinanyenclosedorsemi-enclosed
areasuchasacarport,garage,attic,crawlspace,undera
sundeckorporch,narrowwalkwayorcloselyfencedarea,
oranylocationthatcanbuildupaconcentrationoffumes
suchasastairwell,coveredbreezeway,etc.
CAUTION
A. Venting Termination Requirements
1. Terminationmustexhaustaboveairinletelevation. It is
strongly recommended that at least 1.5m of vertical
pipe be installed when appliance is vented directly
through a wall.Thiswillcreateanaturaldraft,which
willhelppreventthepossibilityofsmokeorodorventing
intothehomeduringapoweroutage.Itwillalsokeep
exhaustfromcausinganuisanceorhazardbyexposing
peopleorshrubstohightemperatures.Thesafestand
preferredventingmethodistoextendtheventvertically
throughtheroof.
2. Distancefrom doorsandopeningwindows,orgravityor
ventilationairinletsintobuilding:
a. Notlessthan1.2mbelow;
b. Notlessthan1.2mhorizontallyfrom;
c. Notlessthan305mmabove.
3. Distancefrompermanentlyclosedwindows;
a.Not less than 305mm below; horizontally from or
above.
4. Distancebetween bottomofterminationandgradeshould
be305mmminimum.Thisisconditionaluponplantsin
thearea,andnatureofgradesurface.Thegradesur-
facemustbeanon-combustiblematerial(i.e.,rock,dirt).
Thegradesurfacemustnotbelawn.Distancebetween
bottom of termination and public walkway should be
2.13mminimum.
5. Distance to combustible materials must be 610mm
minimum.  This includes adjacent buildings, fences,
protrudingpartsofthestructure,roofoverhang,plants
andshrubs,etc.
6. TerminationCapLocation(HomeElectricalService)
• Side-to-sideclearanceistobethesameasminimum
clearancetovinylinsidecorners.
• Clearanceofaterminationcapbelowelectricalservice
shallbethesameasminimumclearancetovinylsofts.
• Clearanceofaterminationcapaboveelectricalservice
willbe305mmminimum.
• Locationoftheventterminationmustnotobstructor
interferewithaccesstotheelectricalservice.

Vent Information
B. Avoiding Smoke and Odors
Negative Pressure, Shut-Down and Electrical Power
Failure
Toreducetheprobabilityofback-draftingorburn-backin
thepelletapplianceduringpowerfailureorshutdowncon-
ditions,it 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seperately.
Peryourlocal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 those and other
appliances.
Whentheapplianceisroofvented(stronglyrecommended): 
The air intake is bestlocated onthe exteriorwall ori-
ented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appli-
ance.Itmaybenecessarytoaddadditionalventilationto
thespaceinwhichthepelletapplianceislocated.
Consultwithyourlocalheatingprofessionaltodetermine
theventilationdemandsforyourhouse.
