DuraVent FasNSeal PVC to FasNSeal Appliance Adapter: connects PVC to FasNSeal in seven size combinations
The DuraVent FasNSeal PVC to FasNSeal Appliance Adapter is an adapter that joins a PVC connection to a FasNSeal vent. Choose the PVC size first, then the FasNSeal size: 2 to 3, 3 to 3, 4 to 4, 4 to 6, 4 to 7, 6 to 4, or 6 to 6 inch. DuraVent names no specific appliance models for this part. 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.
FasNSeal serves natural gas or propane appliances that call for a special gas vent. The appliance maker determines the allowed vent length and whether it can exit through a wall or roof. The pipe needs separate support. Horizontal runs need hangers every 6 feet. Wall brackets go after a turn into a vertical run of 10 feet or more, every 12 feet vertically, and after each offset. Each floor or ceiling crossing needs a firestop. Comparing appliance connections? See the DuraVent FasNSeal Universal Appliance Adapter. The DuraVent FasNSeal PVC to FasNSeal Appliance Adapter ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
