DuraVent FasNSeal Fulton Boiler Appliance Adapter: connects a FasNSeal vent to a Fulton boiler
The DuraVent FasNSeal Fulton Boiler Appliance Adapter is the part that joins a FasNSeal vent to a Fulton boiler’s exhaust outlet. DuraVent lists this adapter for Fulton boilers without naming a particular boiler model. It comes in 4 inch and 6 inch sizes, so the size of that connection matters when ordering. 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.
Choose the 4 inch or 6 inch size on this page. That measurement is the inside diameter of the vent and should match the boiler’s exhaust outlet. Before ordering, check the boiler maker’s venting instructions to confirm which vent it accepts and how the connection is made. Looking for the tapered version? See the DuraVent FasNSeal Fulton Tapered Appliance Adapter. The DuraVent FasNSeal Fulton Boiler Appliance Adapter ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
