Ez Link System Dual Installation - Rheem 812 Series Owner's Manual And Installation Instructions

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 812, 816, T16, 820, 826 and
T26 model continuous flow gas water heaters. The EZ Link Kit PN 299291 is required for the installation.

Notes:

Only two continuous flow gas water heaters can be installed with an EZ Link system.
 The Rheem EZiSET system cannot be used on the 874 series – NZ or an 876 series water heaters if two
of these water heaters are 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.

It is recommended the two water heaters be set with the same preset outlet temperature setting.

A temperature controller(s) may be installed but is not required to be installed with the EZ Link system on
a Rheem 874 and 876 series 812, 816, T16, 820, 826 and T26 model dual installation. The controller can
be either a standard or Deluxe controller.

If the EZ Link system is used with a water heater with a preset outlet temperature greater than 60°C and
a temperature controller is installed, the maximum outlet temperature of the water heater will be limited
by the maximum temperature setting of the temperature controller.

Two 874 series 812, 816, T16, 820, 826 or T26 model water heaters manifolded together and 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: Temperature controllers must not be fitted to a water heater (874 series) if it is installed as
an in-series gas booster with a solar water heater system because water at a temperature much higher
than the controller setting can be delivered.
