Ao Smith 100227698 Tankless Water Heater 140000 Btu/h

Product Description

The AO Smith 100227698 is an outdoor-rated natural gas tankless water heater designed for both commercial and residential applications. It delivers up to 140,000 BTU/h of heating capacity with a flow rate of 6.6 gallons per minute, making it suitable for high-demand hot water systems. The unit operates with a direct or power vent configuration and carries an energy factor of 0.81. It is a non-condensing design, meaning it exhausts higher-temperature flue gases and requires appropriate venting materials rated for that duty. Licensed plumbers and HVAC technicians are the primary installers for this type of equipment.

This tankless water heater is built for outdoor installation, eliminating the need for indoor venting runs in many retrofit or new-construction scenarios. At 6.6 GPM and 140,000 BTU/h, it is sized to handle simultaneous fixture demand in light commercial settings or larger residential systems. Its dual commercial and residential listing makes it a versatile option where hot water load calculations call for on-demand, non-storage heating. The direct or power vent setup allows flexibility in exhaust routing depending on the job site layout.

Installation Notes

Installation must be performed by a licensed plumber or qualified gas technician in accordance with local mechanical codes and the manufacturer instructions. Shut off the gas supply and water supply completely before beginning any connection work. The power vent configuration requires a dedicated electrical supply for the blower motor, so verify circuit requirements before rough-in. Non-condensing exhaust venting must use materials rated for high-temperature flue gas — consult local codes and the installation manual for approved vent pipe specifications.
