6/b observing the positions shown in
the table.
NOTE: This type of adjustment cannot
by carried out on model "SOLO 20".
2.6 HEATER UNIT
In "SOLO 20 - 30" and "AQUA 30"
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 hold-
er 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.
13/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 30" model has a lower
power heater which remains on all the
time after the main switch is turned
on in the control panel in winter 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 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 tempera-
ture for st ar t-up. "SOLO 40" and
"AQUA 40" model have no heater unit,
as it is not required.
