available. This is verifiable via the indication on the packaging and on the
data badge;
c) Check that the flue pipe has an adequate draft, does not have any
constrictions or obstructions, and that no other appliance’s flue outlets have

according to the specific standards and regulations in force. The connection
between the boiler and flue outlet can be made only after this verification has
been carried out.
