• 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 automatically
vents via the air-vent valve.
