(15.fig..10)
.
The.bridge.must.always.be.disconnec-
ted..It.is.connected.only.when.multiple.
boilers. are. installed. in. a. sequence/
cascade..
.
ATTENTION: All of the operations
described above must be carried out by
authorised personnel.

TEMPERATURE SENSORS
In.
Table 1
.the.resistance.(Ω).values.are.
given.. They. are. obtained. by. the. feelers.
when.the.temperature.varies.and.by.the.
transducers.when.the.pressure.varies.
With the C.H. sensor (SM) interrupted
the boiler will not function with both
services.
With the D.H.W. sensor (SB) interrupted
the boiler functions only with heating.
3.3
ELECTRONIC IGNITION
The.starting.and.flame.sensing.are.control-
led. by. two. electrodes. that. guarantee. the.
maximum.safety,.with.a.time.of.intervention.
of.one.second.for.accidental.switching.off.or.
lack.of.gas.
3.3.1 Functioning cycle
Turn. the. selector. knob. to. summer. or.
winter.and.note,.from.the.lighting.up.of.
the. green. led. ( ). whether. electricity. is.
present..
The.starting.up.of.the.pilot.burner.should.
take.place.within.20.seconds..
With. the. pilot. burner. on. the. electronic.
panel. opens. the. second. electro-valve.
and. proceeds. with. the. starting. of. the.
main. burner.. We. can. summarise. the.
manifestations.of.a.failure.to.start,.with.
consequent. activation. of. the. failure.
signal.as.follows:
–.
Lack of gas
. The. starting. electrode. continues. to.
spark. for. a. maximum. of. 20. seconds,.
the. pilot. burner. does. not. start,. the.
blockage.indicator.lights.up.
. This. may. occur. at. the. first. starting.
attempt.or.after.long.periods.of.inac-
tivity. with. the. presence. of. air. in. the.
tubing..May.be.due.to.the.gas.tap.being.
closed. or. a. break. in. the. valve. coil,.
which.do.not.allow.opening..
–.
The starting electrode does not give a
jump spark.
. In. the. boiler. only. the. gas. opening. to.
the. burner. is. noted,. after. 20. seconds.
the..block.signal.lights.up.
. May. be. due. to. the. fact. that. the. cable.
of. the. electrode. is. interrupted. or. is.
not. well. fixed. to. the. terminal. of. the.
Ignition.transformer.
–.
The flame is not detected
. From. the. time. of. the. starting. a. conti-
nuous. jump. spark. from. the. electrode.
is. noted. despite. the. pilot. burner. being.
lit..After.20.seconds.the.sparking.stops,.
the.burner.goes.off.and.the.block.signal.
lights.up..
. The. cable. of. the. detector. electrode.
is. interrupted. or. the. electrode. itself.
is.earthed;.the.electrode.is.very.worn.
and.needs.to.be.replaced..The.electro-
nic.panel.is.faulty..
Due. to. a. sudden. fall. in. electricity. the.
burner. is. immediately. arrested,. once.
the.electricity.is.restored,.the.boiler.will.
automatically.restart.
3.4
SMOKE SAFETY DEVICE
It.is.a.safety.measure.against.the.outflow.
of. smoke. into. the. environment. due. to.
inefficiency.or.a.partial.clogging.up.of.the.
smoke.stack.(fig..11)..It.acts.by.blocking.
the.gas.valve.when.the.release.of.smoke.
into.the.environment.is.continuous.and.in.
such.a.quantity.as.to.be.dangerous..
To.restart.the.boiler,.unscrew.the.cover.
of.the.thermostat.and.reactivate.the.but-
ton. beneath.. After. 10. minutes. from. the.
restarting.of.the.thermostat,.the.electro-
nic.panel.will.reactivate.the.boiler.
For. immediate. reinstating,. after. having.
reset.the.thermostat,.switch.off.the.boi-
ler.and.wait.a.few.seconds.before.restar-
ting.it..If.the.blockage.occurs.repeatedly.

NOTE: In order to have access to the regulating trimmer, (6) and (10), take out
the heating potentiometer knob.
ATTENTION: The C.H. and D.H.W. circulating pums start to operate, in both
services, when the boiler temperature reaches 40°C in order to prevent for-
mations of condensation.
