It is part of the InnoFlue venting product line and is designed for use on residential and light-commercial gas appliances — including furnaces, water heaters, and boilers — where the appliance flue collar is sized for PVC but the installed vent system uses polypropylene components. The adapter connects at the appliance boiler connection point and integrates directly into InnoFlue PP vent system components. It is installed by licensed HVAC technicians and plumbers performing vent system connections on high-efficiency combustion appliances.\u003c\/p\u003e\n\u003cp\u003eThis adapter is intended for appliances that require a PVC-to-polypropylene transition at the flue collar. Approved applications include specific makes and models of furnaces, water heaters, and boilers whose manufacturers have authorized the use of this adapter. Consult the Centrotherm OEM manual for the specific appliance to confirm which appliance adapter part number is required before installation. The 3-inch diameter fits flue collar and vent pipe sized at 3 inches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions a PVC appliance flue collar to an InnoFlue polypropylene vent system without glue or primer\u003c\/li\u003e\n  \u003cli\u003eEvaluated to UL1738 and ULC S636 by ICC for certified performance\u003c\/li\u003e\n  \u003cli\u003eApproved for use on specific furnaces, water heaters, and boilers per appliance manufacturer authorization\u003c\/li\u003e\n  \u003cli\u003eSingle-wall, long-pattern construction for direct boiler connection fitment\u003c\/li\u003e\n  \u003cli\u003eInstalls quickly without adhesives, reducing labor time on the connection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eApproved for use on specific makes and models of furnaces, water heaters, and boilers that require a PVC flue collar to polypropylene vent system transition.
