DuraVent FasNSeal Peerless and Lochinvar Appliance Adapter: a 3 inch connection for the listed appliance models
The DuraVent FasNSeal Peerless and Lochinvar Appliance Adapter is a 3 inch adapter that joins a FasNSeal vent to an appliance’s exhaust outlet. DuraVent lists it for the Lochinvar Efficiency+ EBN 100 and Peerless DE Series and PSC Series boilers. Match that model listing to your appliance before ordering, rather than choosing by brand name alone. 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. Its stainless steel pipe has welded seams.
DuraVent calls for high temperature silicone sealant at the connection to these appliances. The sealant is not included. An experienced professional should handle the vent work, and DuraVent recommends having a qualified inspector check the entire vent each year. Looking for the PDE adapter instead?

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