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.
