DuraVent FasNSeal Viessmann Vitodens Series Appliance Adapter: joins a FasNSeal vent to a Vitodens boiler
The DuraVent FasNSeal Viessmann Vitodens Series Appliance Adapter is an adapter that connects a FasNSeal vent to a Viessmann Vitodens boiler’s exhaust outlet. Choose a 3 inch or 4 inch size on this page. DuraVent does not identify specific Vitodens models for this adapter, so have your installer confirm compatibility before ordering. 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 vent has welded stainless steel seams. An experienced professional should handle the installation, and DuraVent recommends a qualified inspector check the whole vent each year.

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