Rinnai RSC199EP 160,000 BTU Exterior Natural Gas Tankless Water Heater

CIRC-LOGIC RECIRCULATION TECHNOLOGY

Rinnai Circ-Logic recirculation technology allows users to set recirculation patterns that coincide with their hot water usage patterns. Hot water is available when needed, without the expense of circulating it during times of inactivity. Two recirculation modes are available:

• Dedicated Mode: With a dedicated return line, the integrated pump recirculates water from the tankless water heater through the return line and back to the heater.
• Crossover Mode: In applications where a dedicated return line is not available or is difficult to install, Circ-Logic technology allows for the simple installation of a Thermal Bypass Valve (included with purchase) at the fixture farthest away from the water heater.

EASE OF INSTALLATION AND SERVICEABILITY

• Compact Design to Save Space
• Wi-Fi Technology for Remote Monitoring and Management
• Simple Gas Conversion

SENSEi™ WATER FLOW CURVE

Flow curves apply only to incoming water temperatures of 70° F (21° C) or less. For incoming water temperatures greater than 70° F (21° C), please contact Rinnai.

SENSEi™ DIMENSION

SENSEi .. PUMP PERFORMANCE AND PUMP + T ANKLESS PERFORMANCE CURVE

Water Flow (GPM)

• Recirculation Pump Control

  • Smart-Circ™ “learns” users’ hot water patterns to activate recirculation.
  • Manual schedule selection is available with Accessory controllers (MC-195T or control r™ Wi-Fi module)

• Internal Multi-Speed DC Pump
  Integrated pump allows for recirculation through a dedicated return line or crossover with thermal bypass valve.

• Maximum Recirculation Pipe Lengths

  • 400 equivalent feet for 3/4 in. pipe diameter

  • 100 equivalent feet for 1/2 in. pipe diameter
    Take equivalent elbow lengths into consideration when calculating pipe length.

  • For dedicated return lines: Total length includes both hot water supply and dedicated return lines.

  • Cross-over mode: Total length includes both hot water supply and cold water piping length from the tankless water heater to the thermal bypass valve. Cross-over mode requires the use of a thermal bypass valve (included).
