Important
This appliance is suitable for G20 gas containing up to 20% hydrogen (H
2
). Due to variations in the percentage of
H
2
, the percentage of O
2
may vary over time. (For example: 20% of H
2
in the gas may lead to a 1.5% increase of
O
2
in the flue gases) The gas valve may need to be adjusted more accurately. This must be adjusted using
standard O
2
values for the gas used.
3.1.4 Factory test
Before leaving the factory, each appliance is optimally set and tested for:
Electrical safety
Adjustment of (O
2
/CO
2
).
Domestic hot water function (bi-thermal boilers only)
Tightness of the heating circuit
Tightness of the domestic water circuit
