About this file
This is an engineering specifications document for the Rinnai CU199i-N internal condensing tankless water heater, which appears to be part of a Bureau of Prisons solicitation for water heater replacements at FCC Coleman.
The specifications detail requirements for commercial condensing, multiple point-of-use, gas-fired water heaters that must be ANSI Z21.10.3 certified with an Energy Star rating. Key technical specifications include: 97% thermal efficiency, 0.93 Uniform Energy Factor, max 20 ppm NOx emissions, 15,000-199,000 BTU/hr input range, 9.8 GPM maximum hot water capacity, microprocessor control with direct electronic ignition, and internal safety features. The unit operates on natural gas and 120V/60Hz power. The warranty covers the heat exchanger for 8 years/12,000 hours, other parts for 5 years, and labor for 1 year.

Water Heater(s) shall be microprocessor controlled and utilize a direct electronic ignition system (with no standing pilot), fully modulating gas control valve, turbine flow meter, automatic electro-mechanical water flow control valve, and water temperature thermistors to maintain outlet water temperature between ± 2°F of set point temperature. Microprocessor shall have built in recirculation logic to control a pump’s heating cycles.
Water Heater(s) shall incorporate the following internal safety devices: flame failure lockout, boiling protection lockout, thermal overheat protection, internal freeze protection for ambient temperatures as low as –22°F, and lockout protection in the event of a blocked flue.
Water Heater(s) shall be provided with a temperature thermostat with an adjustable set point range of 98°F to 185°F.
Water Heater(s) shall also be capable of storing and displaying a history of up to nine diagnostic maintenance codes, via the display on the temperature thermostat controller.
Water Heater(s) shall have downward fired fiber mesh burners, solid brass water flow control valve, and solid brass inlet and outlet water connections.
Water Heater(s) shall have a primary stainless steel heat exchanger and a secondary stainless steel heat exchanger warranted against material defects or workmanship for a period of
• Heat Exchanger: 8 years or 12,000 operation hours, whichever occurs first
• All Other Parts and Components: 5 Years
• Reasonable Labor: 1 Year
