DuraVent FasNSeal Cleaver Brooks MCF Series Appliance Adapter: connects FasNSeal to listed Cleaver Brooks boilers
The DuraVent FasNSeal Cleaver Brooks MCF Series Appliance Adapter is an adapter that joins a FasNSeal vent to a Cleaver Brooks boiler’s exhaust outlet. DuraVent lists the 6, 8, 10, and 12 inch sizes for MCF Series boilers. It also lists the 8 inch for the CFC 1000 and the 12 inch for the CFC 1800. 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, 8, 10, or 12 inch on this page. That measures the vent’s inside diameter and should match the boiler’s exhaust outlet. The boiler maker’s instructions determine the vent choice and connection. The vent also needs support along its route. Horizontal runs need hangers every 6 feet. Wall brackets are needed after a turn into a vertical run of 10 feet or more, every 12 feet vertically, and after any offset. Each floor or ceiling crossing needs a firestop.
