wer.tie.rods,.both.in.the.front.and.rear.side.
of. the. boiler,. two. nuts. are. tightened,. one.
of.which.is.used.to.block.the.side.support.
brackets.
The. assembly. of. the. casing. components.
must.be.carried.out.in.the.following.way:
–. Unscrew.with.some.rotations.the.second.
or.third.nut.of.each.tie.rod.
–. Connect.the.left.side.(1).on.the.lower.and.
upper.tie.rod.of.the.boiler.and.adjust.the.
position. of. the. nut. and. lock-nut. of. the.
upper.tie-rod.
–. Block.the.side.by.tightening.the.locknuts.
–. In. order. to. assembly. the. right. side. (2).
proceed.in.the.same.way.
–. Connect. the. rear. panel. (4). introducing.
the.two.splines.in.the.vents.obtained.on.
each.side.and.lock.it.with.self-threading.
screws.
–. The. protection. deflector. (5). is. fixed. to.
the. control. panel. (6). with. three. self-th-
reading.screws..Insert.the.mineral.wool.
between.the.two.components.
–. Fasten.the.front.panel.(6).using.the.pres-
sure.pins.
–. Unwind.the.capillary.of.the.thermometer.
(7).and.and.introduce.it.in.the.left.sheath.
of.the.rear.head.introducing.the.contact.
spring. which. must. be. cut. at. about. 45.
mm.. The. thermometer. cable. must. be.
placed.above.the.insulation.and.must.not.
contact.directly.the.iron.cast.body.
–. Fasten. the. cover. (8). to. the. sides. of. the.
boiler.using.the.pressure.pins.
-.. Apply. the. BOILER. TECHNICAL. DATA.

NOTICE: Store the "Test report" and "De-
claration of conformity" placed in the
combustion chamber together with the
documents of the boiler.

DRAUGHT REGULATOR
WITH THERMOSTATIC
OPERATION
By. means. of. the. draught. regulator. with.
thermostatic. operation,. a. continuous. va-
riability. of. the. air. introduced. in. the. boiler.
furnace.can.be.obtained.
By.means.of.a.connecting.chainlet,.this.re-
gulator.acts.on.the.lower.primary.air.intake.
port.
Once. the. set. temperature. has. been. rea-
ched,.the.regulator.decreases.the.opening.
of. the. air. intake. port. automatically,. so. to.
slow. down. the. combustion. and. prevent.
over-heating.
In.order.to.optimise.the.combustion.on.the.
upper. load. port,. place. a. round. adjusting.
port. that. distributes. the. secondary. air.
countercurrent.compared.to.the.path.of.the.
combustion.products.
This. process. further. increases. the. yield.
and.allows.exploiting.the.combustion.more.
effectively.
Two. types. of. thermostatic. regulators. can.
be.assembled.on.the.boilers.
"THERMOMAT RT-C" Regulator
"REGULUS RT2" Regulator
4.6.1
"THERMOMAT RT-C" Regulator
(fig. 7)
The. "Thermomat". regulator. is. equipped.
with. a. thermosetting. resin. knob. of. an.
adjustment.field.from.30.to.100.°C..
Screw. the. regulator. on. the. 3/4". opening.
of. the. anterior. head. and. orientate. the. red.
index.on.the.upper.part..
The.lever.with.the.chainlet.should.be.intro-
duced.in.the.regulator.holder.after.having.
assembled. the. instrument. holder. board.
and.after.having.removed.the.plastic.lock..
If. the. joint. is. taken. out,. which. fixes. the.
lever.with.the.chainlet,.take.care.in.assem-
bling.it.again.in.the.same.position..
After.having.placed.the.knob.at.60°C,.block.
the. lever. with. the. chainlet. in. a. slightly.
inclined. position. downwards,. so. that.
the. chainlet. will. be. in. axis. with. the. air.
gate. damper.. For. the. adjustment. of. the.
"Thermomat",. which. essentially. consists.
in.the.determination.of.the.chainlet.length,.
proceed.in.the.following.way:.
–. Place.the.knob.at.60°C.
–. Switch.on.the.boiler.with.opened.air.gate.
damper.
–. When.the.water.temperature.of.60°.C.is.
reached.in.the.boiler,.fix.the.chainlet.in.
such. a. way. on. the. lever. of. the. air. gate.
damper,.in.order.to.obtain.an.opening.of.
about.1.mm..
–. Now.the.regulator.is.calibrated.and.it.is.
possible.to.choose.the.desired.operating.
temperature.by.rotating.the.knob..
4.6.2
"REGULUS RT2" Regulator
(fig. 8)
The. adjustment. field. is. included. betwe-
en. 30. and. 90°C. (fig.. 8).. Follow. the. same.
instructions.of.the."Thermomat".regulator.
for.the.assembly.and.the.activation..
4.7
SAFETY EXCHANGER
The.safety.exchanger.is.supplied.upon.re-
quest.with.a.kit:
-.code.8105200.for.SOLIDA.EV.3/4/5
-.code.8105201.for.SOLIDA.EV.6/7.
The.kit.must.be.used.on.closed.expansion.
tank.systems.with.power.lower.than.35.kW..
Its.function.is.to.cool.the.boiler.in.case.of.
over-temperature,. by. using. a. thermal. di-
scharge.valve.connected..to.the.exchanger.
inlet.hydraulically.
In.correspondence.to.the.exchanger.outlet,.
place. one. drainpipe. with. funnel. and. a.
siphon.that.drive.to.a.suitable.discharge.
The. discharge. must. be. visible. for. inspec-
tion.
ATTENTION: Failure to comply with this
precaution, a possible activation of the
thermal discharge valve can damage per-
sons, animals and objects, which the ma-
nufacturer is not responsible for.
Before commissioning the boiler, ensure
that the water flow of the thermal dischar-
ge valve is guaranteed.
