• PolyPro Flex through B Vent as a Chase.
• Retrofit venting for new high efficiency appliances.
• When replacing a mid efficiency appliance with a new condensing 90+ appliance, you can use the existing B vent (any brand) as a chase for the new appliance with PolyPro
• The perfect solution for utilizing the B Vent already in place, just insert double wall PolyPro Flex through the B Vent pipe, utilizing the convenient pull cone and terminate the system with PolyPro's Skyline Vertical Termination Cap
• At the other end is the unique B Vent-PolyPro Support Cap, allowing for the connection of flex to rigid PolyPro lengths and elbows to finish the installation.
