Filling the heating system and
checking connections for leaks
Check the heating system for leaks before commissioning
to ensure there are no leaks when the system is in
operation.
DANGER: Risk to health from drinking water
contamination!
B Always observe the regulations and
standards applicable in your country for
the prevention of contamination of
drinking water (e.g. by water from heating
systems).
B Observe EN 1717.
CAUTION: Risk of system damage from
excess pressure when testing for leaks!
Pressure, control and safety equipment may
be damaged through excessive pressure.
B Ensure that, whilst you are carrying out a
leak test, no pressure, control or safety
equipment is fitted, which cannot be shut
off towards the boiler water chamber.
CAUTION: System damage due to thermal
stresses!
B Only fill the system when cold (the flow
temperature must be no more than 40 °C).
B When the heating system is in operation,
do not fill it via the boiler fill and drain valve.
Instead, only use the filling valve in the
heating system (return).
B Pay attention to the water quality as
specified in the operator's log, and record
the volume and quality of the water used
to fill the system.
B Fill the heating system with water
(
Chapter 6.2).
B Carrying out the leak test.
The testing pressure is based on the normal operating
pressure of the heating system and should be 1.3 times
that pressure, and in any case no less than 1 bar.
B Check all connections for leaks.
