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.
