DANGER
Incorrect motor rotation can seriously damage property and injure people.

All burner adjustment operations must be carried out by checking combustion using a previously correctly calibrated

fume analyser.
Always check that the chimney is free from obstructions, never obstructed, and that the passage of fumes is always free.

During commissioning operations, do not let the burner operate with insufficient air flow (danger of formation of carbon

monoxide); if this should happen, make the gas decrease slowly until the normal combustion values are achieved.
WARNING
Before executing the connections to the gas pipe network, be sure that the manual cutoff valves are closed.

During normal operation, the parts of the burner closest to the generator (coupling flange) are subject to heating. avoid

touching them to avoid burns.
Before starting the burner up, be sure that the manual cutoff valves are open and check that the pressure upstream the

gas train complies the value quoted on paragraph "Technical specifications". Be sure that the mains switch is closed.

LIMITATIONS OF USE

The burner is an appliance designed and constructed to operate only after being correctly connected to a heat generator (e.g. boi-

ler, hot air generator, furnace, etc.), any other use is to be considered improper and therefore dangerous.
The burner is an appliance designed and built to operate in accordance with the information on its nameplate and specifications in

this manual, any other use is considered improper and therefore dangerous.
The user must guarantee the correct assembly of the appliance by entrusting its installation to qualified personnel, and having the

first ignition carried out by an assistance center authorized by the burner manufacturer. In this regard, the electrical connection to
the regulation and safety devices of the generator is essential (operating, safety, etc. thermostats) which guarantees correct and
safe burner operation.
Therefore, any operation of the appliance which is independent of the installation operations or which takes place after total or par-

tial tampering with these (e.g. disconnection, even partial, of electrical conductors, opening of the generator door, disassembly of
parts of the burner) must be excluded.
Never open or disassemble any component of the machine.

To make the machine safe, operate the main disconnect switch.

BURNER RELEASE OPERATIONS
In the event of anomalies that require the burner to be switched off, it is possible to act on the auxiliary line switch on the front of the

panel, which due to its easy accessibility and speed of operation also acts as an emergency switch, and possibly on the release
button.
In the event of a lockout, the cause must be evaluated. if the flame back warning light is on, before unlocking the control box it is

mandatory to check the integrity and good condition of the combustion head as described in the maintenance paragraph.
In the event of lockout due to flashback, after appropriate checks of the reasons for the lockout and after having implemented the

appropriate solutions, to restart the burner it is necessary to cut and re-apply power using the main switch, before pressing the
reset button.
In the event of a lockout, unlock the equipment by pressing the reset button. in the event of a new lockout, contact technical sup-

port, without making further attempts.
