DuraVent FasNSeal Universal Condensate Drain: a drain for horizontal, vertical, or angled vent runs
The DuraVent FasNSeal Universal Condensate Drain is a stainless steel fitting that removes condensate, the acidic liquid that drips from appliance exhaust. It fits into a horizontal or vertical vent run, or any angle between. If your appliance has no drain of its own, DuraVent strongly recommends placing this fitting right by the appliance outlet. 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 a vent size from 3 to 16 inch on this page. The 3 to 5 inch sizes have a 5/8 inch drain tube. The 6 to 16 inch sizes use a fitting with a 1 inch pipe thread. The run also needs a drain at the base of each vertical section and every 30 feet along horizontal sections. The drain hose needs a loop that acts as a trap. In cold climates, drains must stay indoors. Need a threaded drain for iron pipe? See the DuraVent FasNSeal IPS Drain Fitting for iron pipe.
