Safety

The burner is designed to be installed on

conditions.
It should be used in an area where an
adequate supply of fresh air is available
for correct combustion and where any
vitiated products can be properly
evacuated.
Flue size and design mut be appropriate
to the fuel, in accordance with current
regulations and standards.
Power supply (230 VAC

devices used, must include an

earthed

neutral wire

Otherwise, power supply to the burner
must include an isolating transformer
and appropriate protection (30mA circuit
breaker and fuse).
Burner must be able to be isolated from
the system via a multipole switch
complying with current standards.
Operating staff should always act with
extreme caution and especially avoid
direct contact with areas that are not
heat-insulated and electrical circuits.
Do not splash water on the burner’s
electrical components.
In the event of flooding, fire, fuel leakage
or any other dangerous situation (smell,
suspicious sounds, etc.), stop burner,
