DUCTING
A part of the heated air can be sent via ducting to other rooms using the pre-cut hole (ø 150 for
type 1÷2
; ø 300 for
type 3÷7
) at the top of the distribution plenum.
FIXED PROTECTIONS
In order to avoid accidental contact with moving parts, the heater must not be started without any one of the fixed
protections, which are:
• Lower front panel.
• Rear panel.
• Lateral grille panel.
• Burner cover.
ELECTRIC CONNECTION
Heaters leave the factory internally wired; they need to be connected according to the wiring diagrams on page 9.
The electrical connections must be carried out by professionally qualified personnel and according to current applicable
legislation, using the cable grommets on the control panel and the terminals provided. For the size of the supply line,
refer to the table shown below.
