GAS CONNECTION
M
The system must be equipped with all the accessories required by current regulations.
We recommend the following:
always include a filter, do not apply mechanical strain to the components and, therefo-
re install a flexible joint as well as a pressure stabilizer and an interception cock at the
heating system inlet. The pipes must be laid using rigid pipes. Any flexible pipes must
be type approved.
Also bear in mind the necessary space required for carrying out maintenance opera-
tions on the burner and the boiler. After fitting the valve unit on the burner, check that
there are no gas leaks during the first ignition stage.
