This fitting serves as the starting connector at the appliance outlet, providing a secure transition between the boiler flue collar and the Z-Vent system. It is used in residential and light commercial hydronic heating installations where GV series boilers require properly fitted Category II or Category IV vent termination. Licensed HVAC technicians and plumbers install this adapter during new boiler commissioning or when upgrading existing venting to a Z-Vent configuration.\u003c\/p\u003e\n\u003cp\u003eThis adapter is intended for use with Weil McLain GV Series 3 and Series 4 boilers equipped with a 3-inch flue outlet.
