Connecting Multiple Water Heaters

The V53i can use the EZConnect™ cable which is an optional accessory that connects 2 water heaters and allows them to function as one hot water source.

The V53i can use the MSA-2M and MSA-2S packs which are optional accessories that connect 2 to 5 water heaters and allow them to function as one hot water source.

The V53e cannot use the EZConnect, MSA-2MB, and MSA-2S. The V53e can use Rinnai pressure activation valves (PVA’s) can be used to manifold 2 to 5 Rinnai water heaters in order to produce a stable water temperature and allow the water heaters to run efficiently. Water heaters will turn on as necessary to meet the demand for hot water.

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

•Do not install both the EZConnect™ and the MSA packs because they are not designed to operate together.

•Water heaters connected with the EZConnect™ Cable or the MSA-2M and MSA-2S packs cannot be used for the bath fill function.

•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. (This changes the temperature on all units within the MSA or EZConnect™ system.)
