DuraVent FasNSeal Buderus SB Series Appliance Adapter: connects FasNSeal venting to Buderus SB Series boilers
The DuraVent FasNSeal Buderus SB Series Appliance Adapter is the part that joins a FasNSeal vent to a Buderus SB Series boiler’s exhaust outlet. DuraVent lists the 7, 8, 10, and 12 inch sizes for the SB615 and the 14 inch size for the SB735. Choose the size on this page to match your boiler’s venting requirements. 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 sets the permitted vent length and whether it can exit through a wall or roof. Condensate is the acidic liquid that drips from condensing exhaust. Unless the appliance has its own drain, FasNSeal drains belong near the appliance, at each vertical run’s base, and every 30 feet along horizontal runs. Horizontal venting rises 1/4 inch per foot away from the appliance to direct that liquid back. Have another Buderus boiler?

The DuraVent FasNSeal Buderus SB Series Appliance Adapter ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
