► Check heater before starting and regu-
larly during operation.
► Keep children and animal away from
heater.
► Always separate heater from mains
when not in use.
► Never fi t heater with a different bur-
ner or increase burner output over nomi-
nal power of heater as indicated on specifi
cation adhesive.
► Never block air inlet or outlet since this
could lead to ventilation motor overload
and consequently to overheating of unit.
WARNING! Only the burners
which are chosen and supplied
by the manufacturer can be used.
If another type of burner is used
the heater no longer complies
with CE regulations.
There are three safety devices which are
activated in case of serious malfunction.
The Burner Control Device, which is moun-
ted on the burner and has a restart but-
ton, automatically stops the burner if the fl
ame goes out. The Overheat Thermostat,
TS, of the manuel restart type, is activa-
ted if the temperature of the combustion
chamber rises above the set maximum li-
mit; the warning light (8) lights up and the
heater stops working. The Thermal Relay,
RT, is activated if the fan motor starts to
use more electrical current than the maxi-
mum permitted limit; the warning light (9)
lights up and the heater stops working. If
any of these safety devices are activa-
ted you should check carefully what the
problem actually is before pressing the
restart button and starting the heater off
again (cfr. OBSERVED FAULTS, CAU-
SES AND REMEDIES). Overheat safety
thermostat, TSS, shuts down the heater if
air fl ow is not suffi cient to cool off com-
bustion chamber: the heater will restart
automatically as soon as the heater has
cooled down enough.

► Connect accessories such as the room
thermostat or clock to the unit's electric
switchboard: electric wire must be con-

(7) to the terminals. Having completed all
these operations check carefully that all
electrical connections correspond to the
wiring diagram and check the setting of
thermostat TV (cf. Technical Specifi ca-
tions). When the heater is fi rst turned on
you must check that the fan does not use
more current than the maximum permitted
limit. Finally, to regulate the burner follow
the instructions in the Burner Instruction
Manual.
