6. STANDARD INSTRUMENT PANEL
6.1 Pannel
(Fig. 13)
The instrument panel supplied, made from pla-
stic with index of protection IP40, holds the con-
trol and safety instruments.
The boiler electrical system must be:
- designed and made by qualified personnel
and connected to an earth system in
compliance with the legalisation in force.
- suitable for the maximum power input of the
boiler, using cables with an adequate cross-section.
The earth wire in the power cables and connec-
tion cables to the burner must be a few mm lon-
ger than the other wires in the same cable. For
the connections between the burner, the electri-
cal panel and the power supply, use H07 RN-F
cables for installation in view. For other types of
installation or special environmental conditions,
refer to the legislation in force. The composition
and the diameter of the wires should be calcula-
ted based on the power input of the burner. To
access the instruments, rotate the front panel
(A). To access the terminal block and unwind
the capillary tubes from the thermostats and the
thermometer, remove the top panel (B), after
having unscrewed the 2 side screws (C). The
control thermostats (12-13 - Fig. 16) can be set
by the user, using the knob at the front. The
safety thermostat has a fixed setting and
manual reset, as specified by Italian Min.
