DuraVent FasNSeal Universal Appliance Adapter with Test Port: connects the appliance and provides access for exhaust testing
The DuraVent FasNSeal Universal Appliance Adapter with Test Port is a connector between an appliance’s exhaust outlet and its FasNSeal vent. A technician removes a small plug to check the exhaust and whether the appliance is burning properly. The vent itself is never drilled. 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. It serves natural gas or propane appliances whose makers call for this type of vent.
Choose a size from 3 to 16 inch on this page. The appliance maker determines whether venting can go through a wall or roof and how long it can run. Condensing exhaust leaves acidic liquid that needs drainage. Unless the appliance has its own drain, a FasNSeal drain goes near the appliance, at each vertical run’s base, and every 30 feet horizontally. Horizontal pipe rises at least 1/4 inch per foot away from the appliance to send liquid back toward the drain. Don’t need testing access?
