– the system has been filled and the hydraulic circuit pressure, in a cold state, is correct
– the flue gases are correctly discharged and there are correctly dimensioned vents
– electrical connections and earth connection are correctly carried out
– check that the type of gas is the right one, that the fuel supply line has been correctly built and that the fuel is available
– hydraulic and fuel circuit taps are open

CHECKS AFTER COMMISSIONING

Once the start-up has been performed, check that the appliance stops and then restarts:

– check the tightness of the door gasket and repeat the adjustment in case of leakages
– check the correct operation of pumps
– check the Boiler stop by positioning the system main switch to " OFF "
– check the safety thermostat triggering.
If all the conditions are met, start the Boiler, bring it to its full operation and collect the combustion data.
