a) FasNSealGeneralNotes:
• Donotcut4”FasNSealpipe.ConsultFasNSealinstructionsformethodofcuttingother3”pipe.
• OrientFasNSealventcomponentssothatthearrowsonthepipinglabelsareinthedirectionofuegasow.
• Supporthorizontalpipingsectionsatintervalsof6feetorless.
• VerticalventingsystemsmustbesupportedbyatleastoneFasNSealsupport.Anadditionalverticalsupportis
requiredafteranyoffset.
b)RemovethehoseclampshippedontheFCMventcollar.Bendthethreehoseclamptabsonthiscollaroutward
slightly.Cleantheexteriorofthemaleendoftherstpieceofpipeandtheinsideoftheventcollarontheboiler.
