Noritz EGQ-C3261WX-FF Us Ng Tankless Water Heater 199900 Btu/h

Product Description

The NORITZ EGQ-C3261WX-FF US NG is a high-efficiency condensing tankless water heater designed for residential indoor installations using natural gas. It delivers up to 199,900 BTU/h of heating capacity with a maximum flow rate of 11.1 gallons per minute, making it well suited for homes with moderate-to-high simultaneous hot water demand. The unit operates on a direct vent configuration, drawing combustion air from outdoors and exhausting flue gases through a sealed system. Its 0.98 Uniform Energy Factor reflects condensing-class efficiency, recovering heat from flue gases that non-condensing units waste. Licensed plumbers and HVAC technicians typically handle the installation of this class of equipment.

The EGQ-C3261WX-FF US NG is intended for residential indoor applications where a high-output tankless water heater is needed. Its natural gas fuel type and direct vent design allow flexible placement within conditioned spaces, provided proper venting clearances and combustion air pathways are maintained per the manufacturer guidelines and local mechanical codes. The condensing design makes it especially practical in new construction and high-efficiency retrofit projects where maximizing energy recovery is a priority. The unit is part of the NORITZ EZ Series Pro line, which is engineered to simplify field installation and serviceability.

Key Features

Installation Notes

Installation must be performed by a licensed plumber or qualified mechanical contractor in accordance with the International Fuel Gas Code (IFGC), local building codes, and the manufacturer installation manual. Shut off the gas supply and disconnect electrical power before servicing or replacing any components. Direct vent systems require properly sized concentric or two-pipe vent terminations — verify vent material ratings are compatible with condensing flue gas temperatures and condensate. Condensate drainage must be routed to an appropriate drain in compliance with local plumbing codes.
