HEATER UNIT
In SOLO 25 BF TSE models, t he
heater unit comes on with the consen-
sus 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
temperature has been reached, the
thermostat, which is located above
the preheater (1 fig. 17/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 TSE models has a
78
12
bar
3
lower power heater which remains on
all the time after the main switch is
turned on in the control panel in win-
ter only.
The first time it is turned on at the
beginning of the season, it may be diffi-
cult for the burner to come on, and
the boiler may stop working if the
operating cycle is begun before te cor-
r ect fuel t emper atur e 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.
