Noritz now offers a condensing residential unit with top-mounted connections and flexible venting through existing B-Vent. The new EZTR40 condensing tankless water heater for residential applications is designed to replace a conventional 40-gal. tank-type water heater for two-bath residences in warm-weather climates. The EZTR40 vents with 2” flexible polypropylene tubing that is threaded directly through the existing B-Vent. Water connections are located on the top of the EZTR40, not the bottom. It also uses the same 1/2” gas line used by the old tank unit, which eliminates the need to up-size to 3/4” run in replacement situations. A step-by-step manual and QR code linking to an instructional video are also available.
