EZ-LINK SYSTEM DUAL INSTALLATION
The EZ-Link™ system is designed to electronically control two continuous flow gas water heaters and have
them operate as one. One or both water heaters may be in operation, depending upon the hot water
demand. The second water heater will only operate when the hot water demand exceeds the capacity of the
first water heater to supply.
The EZ-Link system is suitable for installation with Rheem 874 and 876 series 018 and 020 models
continuous flow gas water heaters. The Ez-Link Kit PN 290141 is required for the installation.

Notes:
Only two continuous flow gas water heaters can be installed with an Ez-Link system.
The two continuous flow water heaters must be of the same model. The performance of two different
model water heaters manifolded together cannot be guaranteed.
A temperature controller is required to be installed with the EZ-Link system. The controller can be either
a standard or Deluxe controller.
Two continuous flow water heaters manifolded together with an Ez-Link system installed cannot be used
as an in-series gas booster system to a solar water heater installation. Temperature controllers
must not be fitted to a water heater as part of a solar water heater system because water at a
temperature much higher than the controller setting can be delivered.
