DuraVent FasNSeal Rheem, Ruud RTG, and Paloma PTG and PH Series Appliance Adapter: connects a FasNSeal vent to listed tankless water heaters
The DuraVent FasNSeal Rheem, Ruud RTG, and Paloma PTG and PH Series Appliance Adapter is a 3 inch adapter that joins a FasNSeal vent to a tankless water heater’s exhaust outlet. DuraVent lists it for Rheem and Ruud RTG-42PVN (Pronto 4.2), Paloma PH20RIFSN and PTG42PVN, and Wai Wela PH-16IFSN and PH-20-RIFS models. It provides the connection when the appliance outlet cannot accept FasNSeal directly. 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 3 inch size measures the vent’s inside diameter, which should match the appliance’s exhaust outlet. DuraVent also requires this adapter in addition to its 3 inch insulated 90 degree bird screen wall mount kit. If you’re buying that kit, account for this separate connection part too.

The DuraVent FasNSeal Rheem, Ruud RTG, and Paloma PTG and PH Series Appliance Adapter ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
