tion.
4. Remove the "METANO/GPL" connector
link on the card and set it in the posi-
tion corresponding to the gas to be
used (4 fig. 15).
5. To set the values of maximum and mini-
mum gas pressure, follow the instruc-
tions given in section 4.5. 1 .
6. After have ultimated the conversion of
the boiler, please stick onto the casing
panel the plate showing the relevant flue
which is included conversion kit.
NOTE: When reassembling components

6. Adjust maximum pressure using the
nut (3 fig. 22/a) with a wrench to the
maximum pressure value indicated in
Table 4.
7. Do not adjust minimum pressure until
you have adjusted maximum pressure.
8. Turn off the supply power to the modu-
