Connecting Multiple Water Heaters

The 2-Unit connection cable is an optional accessory that connects 2 water heaters and allows them to function as one hot water source.

The Multi-Unit connection kit and Multi-Unit connection cables are optional accessories that connect 2 to 5 water heaters and allow them to function as one hot water source.

The Multi-Unit connection kit includes a PC board and one Multi-Unit connection cable.

Refer to the instructions that come with the accessory for complete installation information.

Guidelines

•Do not install both the 2-Unit connection cable and the Multi-Unit connection kit because they are not designed to operate together.

•Water heaters should be installed less than 18 inches apart so that the cables will reach between units and to prevent temperature fluctuations (cold water sandwich effect) when the water is shut off and turned back on.

•Temperature settings can only be changed on the controller for the primary unit.
