DuraVent FasNSeal Universal Appliance Adapter with Condensate Drain and Back Flow Preventer: the adapter included in DuraVent’s severe weather kit
The DuraVent FasNSeal Universal Appliance Adapter with Condensate Drain and Back Flow Preventer is a 4 inch adapter that joins a FasNSeal vent to an appliance’s exhaust outlet. It combines the appliance connection, a condensate drain, and a back flow preventer. This is the same adapter included in DuraVent’s Severe Weather Wall Mount Insulated Kit for very wet, cold locations. 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.
Condensate is the acidic liquid that drips from a condensing appliance’s exhaust. Unless the appliance has its own drain, a FasNSeal drain belongs near the appliance, at the bottom of each vertical vent run, and every 30 feet along horizontal runs. FasNSeal parts have a gasket and locking band built into the wider end to seal and secure each connection. Don’t need the preventer? See the DuraVent FasNSeal Universal Appliance Adapter with Condensate Drain. The DuraVent FasNSeal Universal Appliance Adapter with Condensate Drain and Back Flow Preventer ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
