Note the local codes for requirements for connecting an external hot water
cylinder to the boiler. The installation must comply to these codes.
Depending on the domestic hot water requirements and comfort preferences various
external hot water tanks can be connected to the boiler.
Connecting an external hot water tank to the E-Series solo boilers can be done in 2
ways:
1. For E60SR, E85SR and E110SR:
Using an optional three-way valve installed in the return line under the boiler between
boiler and plumbing kit and directly controlled by the boiler control.
2. For E60SR, E85SR and E110SR:
An external hot water tank connected on the secondary side of the optional plumbing
kit, seperately controlled by another device.
The capacity of the boiler must be defined by the installer.
The choice of the tank depends on the coil output.
The coil output of the tank must comply with the boiler output.
For additional information on piping and control of indirect tanks, please see
the Rinnai Boiler Applications Manual.
For additional information on the Rinnai 3-way valve indirect tank kit, please
see the installation manual for the kit.
Rinnai recommends the use of a thermostatic mixing valve on all indirect tanks
used with E boilers on the domestic hot water side to prevent scalding. This
valve will regulate the water temperature leaving the indirect tank.
