Water heater installation
The boiler should be positioned in a
frost-proof boiler room. If the boiler
room is on the roof, the boiler itself may
never be the highest point of the instal-
lation.
When positioning the boiler, please
note the recommended minimum clea-
rance in the picture. When the boiler is
positioned with less free space, mainte-
nance activities will be more difficult.
Connecting the water heater
This chapter will explain how to make
all connections to the boiler with regard
to:
Hydraulic connections
Condensate drain connection
Gas connection
Flue gas connection
Air intake connection
Electrical connection
The boiler should always be connected
in such a way, that the system applies
to all relevant standards and regulati-
ons (European, national and local). It’s
the responsibility of the installer to en-
sure that all standards and regulations
are respected.
Hydraulic connections (1,2,3,4)
Condensate connection (5)
After filling with water, the syphon
(included in delivery) should be
installed to the connection (5) at
the bottom of the water heater.
Connect the hose to the draining
system in the boiler room. The
connection to the draining system
should always be done with an open
connection, in order to avoid flooding
the boiler in case of a blocked drain.
Gas connection (6)
The gas connection must be made by
an authorized installer in accordance
with the applicable national and local
standards and regulations.
Connect the gas line from the system
tension free to the gas connection (6) of
the boiler. A gas cock should be moun-
ted directly behind the boiler.

The Thision WH should be connected to
the mains water supply, The concentration
of chloride in the water supply should be
less than 200mg/l. Should the hardness be
measured at more than 14°dH then a
softener should be installed to bring the
hardness down to between 6°dH and 8°dH.
Caution!
When installing the Thision WH a mains water kit must be used.
The DHWS flow connection should be protected against
a vacuum by use of an anti-vacuum valve.
