GAS CONNECTION
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 com-
ponents and, therefore install a flexible joint as well as a pressure stabilizer and an intercep-
tion 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 operations 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.
