A combustion blower is used to extract the combustion
gasesfromtherebox.Thiscausesanegativepressurein
thereboxandapositivepressureintheventingsystemas
showninFig.7.Thelongertheventpipeandmoreelbows
usedinthesystem,thegreatertheowresistance.Because
ofthesefactswerecommendusingasfewelbowsaspossible
and15feetorlessofventpipe.Themaximumhorizontalrun
shouldnotexceed48".Ifmorethan15feetofpipeisneeded,
thediametershouldbeincreasedfrom3"to4"becausea
larger pipe creates less ow resistance. Be sure to use
approved pellet vent pipe wall and ceiling pass through
ttings to go through combustible walls and ceilings. The
starting collar must be secured to the ue collar with a
minimum of two fasteners. Follow vent manufacturer's
instructions for sealing each joint and/or seam.
Vent Pipe
Pelletventingpipe(alsoknownas"PL"vent)isconstructed
of two layers with air space between the layers. Some
manufacturers produce PLvent designed specically for
corn-burning.Ifplanningtoburncornorothergrains,besure
ventingsystemisapprovedandwarrantedforcorn-burning.
Thesectionsofpipelocktogethertoformanairtightseal,
however,insomecasesaperfectsealisnotachieved.For
thisreasonandthefactthatthePC45operateswithapositive
ventpressurewe recommend that any interior joints also
be sealed with silicone.
Outside Air
Outsideairisoptionalexceptinmobilehomesandwhere
buildingcodesrequire.Thebenetofoutsideairismainly
noticedinsmallverytighthouses.
Toinstalloutsideairuse3"expipe.Thereisabreak-away
hole on the rear panel which must be removed before
connecting the ex pipe. The pipe should be run outside
andterminate3feetormoretothesideorbelowthevent
pipeoutlet.Neverterminatetheoutsideairabovethevent
pipeoutlet.Themaximumlengthrunofthispipeis15feet.
Ifalongerrunisneededthesizemustbeincreasedto3".
