7.3 Recommended nozzles
The burner complies with the emission requirements of the EN
267 standard.
In order to guarantee that emissions do not vary, recommended
and/or alternative nozzles specified by manufacturer in the In-
struction and warning booklet should be used.
If necessary the nozzle of the 1st stage can have a delivery 50%
greater than the total delivery.

Notes on safety for the electrical wiring
Before carrying out any maintenance, cleaning or checking oper-
ations:
It is advisable to replace nozzles every year dur-
ing regular maintenance operations.
The use of nozzles other than those specified by
manufacturer and inadequate regular mainte-
nance may result into emission limits non-con-
forming to the values set forth by the regulations
in force, and in extremely serious cases, into po-
tential hazards to people and objects.
The manufacturing company shall not be liable for
any such damage arising from non-observance of
the requirements contained in this manual.

The electrical wiring must be carried out with the electrical supply disconnected.
Electrical wiring must be made in accordance with the regulations currently in force in the country of destination
and by qualified personnel. Refer to the wiring diagrams.
The manufacturer declines all responsibility for modifications or connections different from those shown in the wir-
ing diagrams.
Do not invert the neutral with the phase in the electrical supply line.
Check that the electrical supply of the burner corresponds to that shown on the identification label and in this man-
ual.
The burner has been type-approved for intermittent use.
In the event of continuous operation, a cycle arrest must be ensured within 24 hours with the use of a time switch
positioned in series with the thermostatic line. Refer to the wiring diagrams.
The electrical safety of the device is obtained only when it is correctly connected to an efficient earthing system,
made according to current standards. It is necessary to check this fundamental safety requirement. In the event of
doubt, have the electrical system checked by qualified personnel.
The electrical system must be suitable for the maximum power absorption of the device, as indicated on the label
and in the manual, checking in particular that the section of the cables is suitable for that level of power absorp-
tion.
For the main power supply of the device from the electricity mains:
- do not use adapters, multiple sockets or extensions;
- use a multiple pole switch with at least a 3 mm gap between the contacts (overvoltage category III), as envis-
aged by the present safety standards.
Do not touch the device with wet or damp body parts and/or in bare feet.
Do not pull the electric cables.
Disconnect the electrical supply from the burner
by means of the main system switch.
Close the fuel interception tap.
Condensation, the formation of ice and the entry
of water are prohibited!
After carrying out maintenance, cleaning or
checking operations, reassemble the cover and
all the safety and protection devices of the burner.
