ELECTRODES ADJUSTMENT
There are two ignition electrodes and a control electrode. They should be positioned according to the indications supplied in
the figure below.
IMPORTANT: the ignition electrodes and the control electrode must never touch the diffuser, the draught tube or other
metallic parts. If this were to happen they would no longer work, thus impairing operation of the burner itself.
The position of the electrodes should always be checked after any work on the combustion head.

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 components and, therefore 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 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.
