DuraVent FasNSeal Slantfin Concept and New Yorker PVCG Series Termination Appliance Adapter: listed for New Yorker PVCG and Slantfin Concept 21 boilers
The DuraVent FasNSeal Slantfin Concept and New Yorker PVCG Series Termination Appliance Adapter is a 3 inch termination adapter. DuraVent lists it for New Yorker PVCG Series and Slantfin Concept 21 Series boilers. It is listed separately from the appliance adapter for each series. DuraVent does not describe its placement or connection. FasNSeal is DuraVent’s stainless steel vent for high efficiency gas boilers, furnaces, and water heaters, built to carry pressurized exhaust and its acidic condensate outside.
For both boiler series, DuraVent specifies high temperature RTV silicone sealant with this adapter. The sealant is not included. The 3 inch size measures the inside diameter, which should match the appliance’s flue outlet. The boiler maker’s instructions determine which vent it accepts and how it connects.
