2. Installation

2.1 General Instructions

This unit must only be used for its intended purpose.
This unit can be used with heat generators for solid fuels, compatibly with its characteristics, performance and heating
capacity. Any other use is deemed improper and therefore hazardous. Opening or tampering with the unit's components
is not allowed (except for the parts requiring servicing); do not modify the unit to alter its performance or intended use.
If the burner is completed with optionals, kits or accessories, only use original products.
B
BURNER INSTALLATION AND SETTING MUST ONLY BE CARRIED OUT BY QUALIFIED AND SPECIAL-
ISED PERSONNEL, IN COMPLIANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL MAN-
UAL, THE CURRENT PROVISIONS OF LAW, THE PRESCRIPTIONS OF NATIONAL AND LOCAL
STANDARDS, AND THE RULES OF PROPER WORKMANSHIP.

2.2 Installation in boiler

Place of installation

The room where the boiler and burner are installed must have openings to the outside as required by the current regu-
lations. If there are several burners or exhausters that can work together in the same room, the ventilation openings
must be sized for simultaneous operation of all the units.
The place of installation must be free of flammable materials or objects, corrosive gases, dusts or volatile substances
which, drawn by the fan, can obstruct the pipes inside the burner or the combustion head. The room must be dry and
not exposed to rain, snow or frost.
Fix the burner to the door. Make the electrical connections as shown in cap. 4.4 "Wiring diagram" (wiring diagram). If
the burner is installed in a boiler SFL, use the special conversion kit. Insert the temperature probe (contained in the kit)
in the sheathing on the cast-iron boiler shell and make the respective electrical connections.
B
THE BURNER IS DESIGNED TO WORK ON HEAT GENERATORS WITH COMBUSTION CHAMBER IN
NEGATIVE PRESSURE.
THE PELLET HOPPER MUST BE POSITIONED SO THAT THE AUGER/BURNER FLEXIBLE CONNEC-
TION TUBE IS NOT TWISTED AND/OR BENT.
Overtemperature safety device
The heat generator must be equipped with its own protection device against overtemperature. If the device provided for
is a safety thermostat, it must be connected to terminals 20 and 21 of the terminal block located inside the burner (after
removing the jumper). For FERROLI boilers not equipped with safety coil, the kit 033001X0 must be used.
