2.6 HEATER UNIT
In "SOLO 25 BF TS - 35 BF TS PR"
models, the heater unit comes on with
the consensus of the burner, after a
delay of a maximum of 90 seconds
required to bring fuel in the nozzle
holder area up to a temperature of
65°C.
Once this t emperatur e has been
reached, the thermostat, which is
located above the preheater (1 fig.
15/b), will give consensus for the
burner to start.
The heater will remain on for as long
as the burner stays on and go off
when the burne goes off.
The "DUETTO 25 BF TS - 35 BF TS
PR" models has a lower power heater
which remains on all the time after the
68

bar

main switch is turned on in the control
panel in winter only. The first time it is
turned on at the beginning of the sea-
son, it may be difficult for the burner
to come on, and the boiler may stop
working if the operating cycle is begun
before te correct fuel temperature
has been reached.
When it is started again, enough time
will have passed (2 - 3 minutes) for the
fuel to have reached the correct tem-
perature for start-up.
"SOLO 35 BF TS - DUETTO 35 BF TS"
model have no heater unit, as it is
not required.
