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 been fitted, unless the flue pipe
is serving more than one heating appliance, 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.
