DuraVent FasNSeal Columbia LVGD Series Appliance Adapter: connects the vent at a Columbia appliance outlet
The DuraVent FasNSeal Columbia LVGD Series Appliance Adapter is the part that joins a FasNSeal vent to a Columbia appliance’s exhaust outlet. It is sold under the LVGD Series name in 3 inch and 4 inch sizes. DuraVent’s Columbia appliance listing names only the Patriot Series direct vent, paired with the 4 inch adapter. That distinction matters when choosing between the two sizes on this page. 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 path from the appliance to outdoors uses FasNSeal parts throughout. DuraVent does not allow another vent maker’s pipe, fittings, or connection methods in that run because the joints seal differently. Each FasNSeal part has a gasket and a locking band in its wider end to seal and hold the next connection. Looking for the universal version? See the DuraVent FasNSeal Universal Appliance Adapter. The DuraVent FasNSeal Columbia LVGD Series Appliance Adapter ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
