SENSEI™ DIMENSIONS
The SENSEI™ units are designed with specific dimensions for installation. The overall unit dimensions are 18.5 inches (470 mm) in width, 26.4 inches (670 mm) in height, and 11.4 inches (290 mm) in depth.
Front View Description:
The front view illustrates the unit's width and height. It clearly marks the locations and measurements for the connection ports relative to the bottom of the unit. These connections include GAS (D), COLD (C), HOT (B), and PRV (G). Specific measurements are provided in inches and millimeters for each connection point from the bottom edge.
Side View Description:
The side view highlights the unit's depth, showing it to be 11.4 inches (290 mm). It also reiterates the overall height and width.
Bottom View Description:
The bottom view details the arrangement of the connection ports: GAS (D), COLD (C), HOT (B), and PRV (G). Measurements from the bottom edge are provided for each connection, aiding in installation planning.
Connection Port Measurements (from bottom edge):
| Connection | in. | mm |
|---|---|---|
| COLD | 3.56 | 90 |

SENSEI™ WATER FLOW CURVE
The SENSEI™ Water Flow Curve graph illustrates the water flow rate in Gallons Per Minute (GPM) for different Rinnai models (RU199e, RU180e, RU160e, RU130e) across a range of water flow conditions. This data is applicable for incoming water temperatures of 70° F (21° C) or less. Dashed lines on the graph represent flow rates after parameter adjustment. It is important to note that maximum flow rates may vary based on the unit's set temperature, the temperature rise (Delta T), and the installation altitude. For incoming water temperatures greater than 70° F (21° C), users are advised to contact Rinnai.
