DuraVent FasNSeal Smith GV-100 Appliance Adapter: a 4 inch adapter for Smith GV100 Series boilers
The DuraVent FasNSeal Smith GV-100 Appliance Adapter is a 4 inch adapter that connects a FasNSeal vent to a boiler’s exhaust outlet. DuraVent lists this part for Smith cast iron GV100 Series boilers. 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.
The appliance maker determines whether the vent can leave through a wall or go up through the roof, and how long the run can be. FasNSeal parts have a gasket and a locking band built into the wider end to seal and secure the connection. Each joint takes up 2 inches of pipe length, which matters when planning the vent run. Have a Smith Lexington boiler instead? DuraVent lists the DuraVent FasNSeal Elbow Appliance Adapter for those boilers. The DuraVent FasNSeal Smith GV-100 Appliance Adapter ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
