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.
