Electrical wiring

Notes on safety for the electrical wiring
 The electrical wiring must be carried out with the electrical supply disconnected.
 Electrical wiring must be carried out by qualified personnel and in compliance with the regulations currently in force
in the country of destination.
Refer to the electrical layouts.
 The manufacturer declines all responsibility for modifications or connections different from those shown in the
electrical layouts.
 Check that the electrical supply of the burner corresponds to that shown on the identification label and in this
manual.
 Do not invert the neutral with the phase in the electrical supply line.
Any inversion would cause a lockout due to firing failure.
 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
DANGER
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 input power of the device,as indicated on the label and in
the manual, checking in particular that the section of the cables is suitable for the input power of the device.
 For the main power supply of the device from the electricity mains:
- do not use adapters, multiple sockets or extensions;
- use an omnipolar switch with an opening of at least
by the current safety standards.
 Do not touch the device with wet or damp body parts and/or in bare feet.
 Do not pull the electric cables.

Flame signal measurement

Min value for a good signal: 70 μA.
If the value is lower, it can be due to:
• Worn scanner;
• Low current;
• Bad set up of the burner.
In order to measure the current, use a microammeter of 100 mA
c.c., connected to the scanner, as in the diagram, with a capacitor
of 100 mF - 1V c.c. at the same level of the instrument. See
(Fig. 42).
