Notes on safety for the electrical wiring

Before carrying out any maintenance, cleaning or checking oper-
ations:

If the cover is still present, remove it and proceed with the electri-
cal wiring according to the wiring diagrams.
Use flexible cables in compliance with the EN 60 335-1 standard.

5.12.1 Supply cables and external connections 

passage

All the cables to be connected to the burner should be passed
through cable grommets, as shown in Fig. 25.

DANGER



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.



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 operation (FS1). 
This means that it should be stopped compulsorily at least once every 24 hours to enable the control box to per-
form checks of its own start-up efficiency. Normally, burner stopping is guaranteed by the boiler's thermostat/pres-
sure switch. 
If this is not the case, a time switch should be fitted in series to TL to stop the burner at least once every 24 hours.
Refer to the wiring diagrams.



The burner is factory set for FS1 operation (1 stop every 24 hours); it can be converted to FS2 operation (continu-
ous - 1 stop every 72 hours), by changing the parameters using the menu of the AZL Display.



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. Do not use the gas tubes as an earthing system
for electrical devices.



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;
- make provisions for an omnipolar switch with a gap between the contacts of at least 3 mm (over-voltage cate-

gory III), as required by current safety regulations.



Do not touch the device with wet or damp body parts and/or in bare feet.



Do not pull the electric cables.

DANGER

Turn off the burner's power supply using the main
system switch.

DANGER

Turn off the fuel interception tap.

DANGER

Avoid condensate, ice and water leaks from form-
ing.

WARNING

To guarantee the protection level of the burner, it
is necessary to close any holes and fairleads not
used using the plugs supplied.

After carrying out maintenance, cleaning or
checking operations, reassemble the cover and
all the safety and protection devices of the burner.
