theuestubwithatleastthreescrews,andsealedwithhigh

4" stainless steel ex vent piping is only allowed for use
in masonry replaces and chimneys or factory built wood

Pellet venting pipe (also known as Type L or PL 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
AccentraInsertoperateswithapositiveventpressure,we
specifythatthejointsalsobesealedwithsilicone.
Wherepassingthroughanexteriorwallorroof,besuretouse
theappropriatepass-throughdeviceprovidinganadequate
vaporbarrier.Ventingmanufacturersgenerallyprovidethese

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.
