- check the ∆p gas values in domestic hot water
and heating modes;
- check the CO
2
in the combustion products at
maximum and minimum ow rate;
- check activation of the safety device in the event
of no gas, as well as the relative activation time;
- check activation of the main switch located
upstream from the boiler and in the boiler;
