DuraVent FasNSeal Universal Appliance Adapter with Condensate Drain: adds a drain at the appliance’s exhaust outlet
The DuraVent FasNSeal Universal Appliance Adapter with Condensate Drain is an adapter that connects a FasNSeal vent to an appliance’s flue outlet, where exhaust leaves the appliance. Its built in drain sits right at that connection. DuraVent strongly recommends a drain there if the appliance does not have its own. DuraVent lists this adapter for the EcoTemp 40HI. 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 3 inch or 4 inch size on this page. A drain hose runs from the adapter’s drain, with a loop in the hose forming a trap. FasNSeal uses stainless steel with welded seams. An experienced professional should handle the installation, and DuraVent calls for a qualified inspector to check the entire vent each year. Looking for a version with a back flow preventer?
