Performing a gas family check

Danger!
Risk of poisoning!
Inadequate combustion quality (CO), indic-
ated by F.92/93, leads to an increased risk of
poisoning.
▶
Make sure that the fault is completely
eliminated before starting up the product
for continuous operation.
Menu → Installer level → Test programs → Gas family
check
The gas family check checks the product setting with regard
to combustion quality.
Note
If additional condensing units are connected to the
same flue gas pipe in the heating installation, en-
sure that none of these condensing units are in
operation or start operating throughout the entire
test programme, so that the test result is not dis-
torted.
▶
Perform the gas family check as part of routine product
maintenance work, after replacing components, carrying
out work on the gas route and following gas conversion.
