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 Section 6.2.1 to 6.2.3).
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 meas-
urement 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 combus-
tion 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 6.2.1.
Proceed to put the boiler into operation as follows:
> Check the maximum gas flow rate as detailed in
Section 6.2.2.
> Check the gas inlet working pressure as detailed in
Section 6.2.3.
> 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.

6.2.1 Checking for tightness of the flue gas
installation and flue gas recirculation
> Check the integrity off the flue gas installation
according to TB 200.
> Should the flue gas installation be longer than 2 m we
strongly recommend to check the system for flue gas
recirculation as described below.

Legend:
1 Flue gas measure point
2 Air measure point
> For checking the system for recirculation use the air
measure point (2).
> Use the flue gas analyser.
> If you detect any CO or CO
the flue gas leakage or recirculation.
> Correct the defects.
> Check again as described before, if there is any CO or
CO in the fresh air.

> If you cannot correct the defects you must not start
up the boiler.
