a
Danger!
Risk to life due to poisoning!
CO is an extremely toxic gas. Risk to life
due to excessive CO concentrations.
> If you are not able to adjust the boiler
correctly and the flue gas values remain
higher than allowed in ¬table12.1, call
the Vaillant Service Solutions (0870
6060 777).
> Do not start up the boiler!
12.1.5 Performing the gas family check
a
Danger!
Risk to life due to poisoning!
CO is an extremely toxic gas. Risk to life
due to excessive CO concentrations. Fault
codes F.92 or F.93 may occur as result of
the gas family check.
> Correct the failure unconditionally before
starting up the boiler for continuous
operation.
Menu ¬ Installer level ¬ Test programs ¬Gas family
check
The gas family check checks the boiler setting with regard
to combustion quality.
> Perform the gas family check:
– as part of regular boiler maintenance
– after replacing components or working on the gas
route.
