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 612, 616, E16, 618 and
620 model 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 Ez-Link system will vary the start up sequence of the two water heaters.
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.
Rheem 874 and 876 series 612, 616, E16, 618 and 620 model water heaters do not require a
temperature controller to be installed as part of an Ez-link system installation.
A temperature controller(s) may be installed with the EZ-Link system on an 874 and 876 series 612,
616, E16, 618 or 620 model dual installation. The controller can be either a standard or Deluxe
controller.
If the preset outlet temperature of the water heater is set at greater than 60°C, the maximum outlet
temperature of the water heater will be limited by the maximum temperature setting of the temperature
controller, if one is installed.
Two 874 series 612, 616, E16, 618 or 620 model water heaters manifolded together with an Ez-Link
system installed can be used as an in-series gas booster system to a solar water heater installation so
long as a temperature controller is not installed.
Warning: 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 if a temperature
controller is installed. 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.
