START UP OPERATIONS
The boiler first start up operation must be carried out by professionally
qualified personnel. Later, it will start automatically.
The user, for instance, may need to re-start the boiler personally after a long
period of inactivity.
Therefore, ensure:
- that the fuel and thermal plant water cocks are open;
- that the hydraulic system pressure when not working is over 1 bar and
lower than the boiler max allowed limit;
- that the boiler regulation thermostat is set between 60 and 90°C;
- that the environment thermostat is “ON” and set on 20°C;
- that the plant pumps are not blocked.
Turn on the main general switch and later the main switch from the control
panel.
The appliance will run an ignition cycle which will last until set temperatures
have been reached.
After this operation has been completed, the system will run automatically.
In case of ignition failures or malfunctioning, turn off the appliance and contact
professionally qualified personnel.
