DuraVent FasNSeal Aerco International Appliance Adapter: connects FasNSeal vent to listed Aerco commercial boilers
The DuraVent FasNSeal Aerco International Appliance Adapter is an adapter that joins a FasNSeal vent to an Aerco commercial boiler’s flue outlet, where exhaust leaves the appliance. DuraVent lists the 6 inch version for the Aerco Benchmark 750, Benchmark 1000, Benchmark 1.5, and KC-1000. It also shows an 8 inch version in a boiler room drawing for the Benchmark 2.0. 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 6 inch or 8 inch on this page. DuraVent provides only the part name, sizes, and those appliance references, so have your installer confirm the connection before ordering. FasNSeal’s stainless steel construction includes welded seams. An experienced professional should handle the vent work, and DuraVent recommends a yearly check of the entire vent by a qualified inspector. Have a Cleaver Brooks boiler instead?
