• Observe the pressure gauge of the
safety equipment assembly when filling
the system with water.
• For boilers with DHW cylinder, vent
the heating coil at a system pressure
of approximately 0.50 bar or less by
starting the DHW cylinder loading
pump (operating time approximately 2
minutes).
• Check the entire system for water leaks.
• Check the safety valve function.
• Ventilate the boiler (e.g. via an automatic
air-vent valve).
• Fill the system to 1 bar pressure.
In operation, the pressure gauge must
indicate between 1 and 2.5 bar.
• Top up with water when the system
pressure falls severely.
•
In constant mode, the boiler automati-
cally vents via the air-vent valve.
