In order to be able to measure this value follow the next procedure:

alternately 2 and OFF will be shown.

the gas valve
- Press the
button until the maximum value is achieved;
The fan will function to its maximum revolutions (burner stays off)
- Measure the under pressure and write down this value.
At the next servicing visit this value may drop 20% of its original value on

boiler needs maintanance.
