Description
The Viessmann 7134770 3″ Flue Adaptor connects boiler flue outlets to compatible venting sections by creating a sealed transition between combustion exhaust components and CPVC piping. Its molded structure channels flue gases from Viessmann B2HA and B2HB boiler models into the exhaust system while preserving alignment at the connection interface. It is installed in condensing boiler HVAC systems where flue routing and exhaust management are required for proper venting operation. Secure adaptor fitment assists with controlled flue gas passage, reduces leakage at joint connections, and provides consistent exhaust flow through connected venting assemblies.
