5.8 Adjusting the by-pass
The appliances have an adjustable by-pass valve.
The pressure can be adjusted between 170 and
350 (mbar) hPa. Approx. 250 (mbar) hPa is preset (mid-
position). The pressure changes by approx. 10 (mbar) hPa
each time the adjusting screw is rotated. By turning
right, the pressure increases and turning left decreases
it.

5.9 Checking the gas setting
b
Caution!
Malfunctions or reduction in working life of
the boiler!
If the boiler version does not correspond to
the local gas family, there will be malfunctions
or you have to change components of the
boiler ahead of schedule.
>
Before starting up the boiler compare the
details of the type of gas specified on the
identification plate with the type of gas
supplied at the installation site (e.g. do not
use an LPG boiler on natural gas).
If the boiler version corresponds to the local gas family:
>
Proceed as described below.
If the boiler version does not correspond to the local gas
family:
>
Perform the gas conversion in accordance with the
gas conversion kit 0020010641.
>
Adjust the gas setting as described below
(see sections 5.9.1 to 5.9.3).
The combustion of this boiler has been checked,
adjusted and preset at the factory for operation on the
type of gas defined on the identification plate. No
measurement of the combustion is necessary to set up
the boiler.
>
Do not adjust the multifunctional automatic gas valve.
>
Ensure
- that the boiler has been installed in accordance with
these instructions,
- the integrity of the flue system and the flue seals, as
described in the flue installation instructions
enclosed with this boiler, and as described below,
- a visual check is carried out on the boiler
combustion circuit and the relevant seals,
- that any defects have been corrected at this stage.
To further validate the integrity of the flue system and
confirm correct operation of the boiler it is possible to
conduct flue gas and air measurements on this boiler -
for details see section 5.9.1.
Proceed to put the boiler into operation as follows:
>
Check the maximum gas flow rate as detailed in sec-
tion 5.9.2.
>
Check the gas inlet working pressure as detailed in
section 5.9.3.
>
Note that you must re-measure the gas flow rate or
the gas inlet working pressure, if changes were
required to correct any issues found.
