4.

For boiler water supply temperatures
over 230°F / 110°C:

Install a type-tested high limit safety
cut-out, if no other has previously
been installed in this system. For this
purpose, install a dual thermostat
(high limit thermostat and high limit
safety cut-out).

5.

Close off test nipples which are not
used for the installation of a probe or
sensor.

Use a Loctite 55 on all threaded steel
nipples on tank.

This is a simplified conceptual drawing

must be field verified. Proper installation
and functionality in the field are the
responsibility of the heating contractor.

Please note:

H

Connect all pipework with detachable
fittings.

H

Seal connections that are not
required, with red brass caps.

H

Equip the DHW circulation pipe with
circulation pump, check valve and
time switch. Gravity operation is only
feasible to a limited degree.

H

Always install DHW tank batteries
with connected DHW circulation.

1.

Pipe together boiler and tank as
illustrated. Connections must be
accessible for service (use factory
supplied adaptors).

2.

Insulate domestic hot water supply
piping.

Due to the potentially high DHW
temperatures generated by the solar
heating system, the domestic hot water
temperature must be limited to a
maximum of 140ºF/60ºC by installing a
mixing device, e.g. thermostatic mixing
valve. The mixing device does not
completely eliminate the risk of scalding
at the tap. The installation of a mixing
tap is required.
