2.5 WATER INLET AND OUTLET PIPING
The locations of the 2" NPT cold water inlet and hot water outlet piping connections are shown
in Figure 2-3a. Flow rates through the unit are limited to 50 gpm continuous.
Shut-off valves and union connections must be installed in the inlet and outlet lines for
maintenance. The use of dielectric unions is recommended.
NOTE
All piping must be arranged so that it does not interfere with
removal of any covers, inhibit service or maintenance, or prevent
access between the unit and walls, or another unit.

2.5.1 WHM Actuator-Controlled Ball Valve Installation
If the Innovation Water Heater was ordered for use with the C-More Water Heater Management
(WHM) system and the actuator-controlled ball valve is not already installed on the unit (Figure
2-3b), it will be packed separately within the shipping container. If installation is required,
proceed as follows:
WHM Ball Valve Installation
1. Remove the ball valve from its stowed location within the shipping container.
2. Attached the valve to the cold water inlet of the unit using the pipe union and nipple
provided.
3. Ensure that the valve is positioned with the actuator enclosure position as shown in Figure
2-3b.
