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.

System damage due to thermal
stresses!
