3.4 Starting the boiler
3.4.1 Preliminary checks
Before starting the boiler it is advisable to check that:
• The flue gas duct has been installed in compliance with
instructions. When the boiler is running no products
generated by combustion are to leak from any of the
gaskets.
• The boiler power supply is 230 V – 50 Hz.
• The system is properly filled with water (pressure on the water
gauge 0.8 / 1 bar).
• All stopcocks in the system’s piping are open.
• The fuel supply stopcock is open.
• There are no gas leaks.
• The external main switch is on.
• The boiler’s safety valve is not blocked.
• There are no water leaks.
To speed up and facilitate igniting the boiler for the first time,
bleed the air out of the gas piping using the gas pressure valve
socket.
Close the pressure socket carefully after bleeding the system.
3.4.2 Starting up and switching off
For starting up and switching off the boiler, follow the “User’s
Instructions”.
