If the boiler version does not correspond to the
local gas family:
>
Call Vaillant Service Solutions (0870 6060 777); Gas
conversions must only be carried out by Vaillant Service
Solutions.
>
You must not start up the boiler yourself.
i
If a gas conversion to liquid gas has been carried
out by Vaillant Service Solutions, the smallest
possible partial load is higher than is shown in
the display. The current values can be found in
the technical data (
¬ section 17
).
The combustion of this boiler has been checked, adjusted
and preset at the factory for operation on the gas group
defined on the identification plate. No measurement of the
combustion is necessary to set up the boiler.
Do not adjust the 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 con-
firm correct operation of the boiler it is possible to conduct
flue gas and air measurements on this boiler - for details
see section
¬ section 10.12.2
.
Proceed to put the boiler into operation as follows:
>
Check the maximum gas flow rate as detailed in
¬ sec-
tion 10.12.3
.
>
Check the gas inlet working pressure as detailed in
¬ section 10.12.4
.
>
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.
10.12.2 Checking for tightness of the flue gas
installation and flue gas recirculation
>
Check the integrity off the flue gas installation according
to TB 008.
>
Should the flue gas installation be longer than 2 m we
strongly recommend to check the system for flue gas
recirculation as described below.

10.6 Flue gas and air measure points
Legend:
1 Flue gas measure point
2 Air measure point
For checking the system for recirculation use the air meas-
ure point (

).
>
Use the flue gas analyser.
>
If you detect any CO or CO
2
in the fresh air, search for
the flue gas leakage or recirculation.
>
Correct the defects.
>
Check again as described before, if there is any CO or
CO
2
in the fresh air.
>
If you cannot correct the defects you must not start up
the boiler.
