INSTALLATION

The.boiler.must.be.installed.in.a.fixed.location.
and.only.by.specialized.and.qualified.firms.in.
compliance.with.all.instructions.contained.in.
this.manual.
Furthermore,. the. installation. must. be. in.
accordance.with.current.standards.and.regu-
lations.
2.1 BOILER ROOM
AND VENTILATION
The."RS Mk II".boilers.with.a.rating.of.more.
than.35.kW.must.be.equipped.with.a.technical.
room. whose. dimensions. and. requirements.
correspond.to.the.current.safety.standards..
The.minimum.height.of.the.boiler.room.must.
comply.with.what.is.indicated.in.fig..3.in.rela-
tion.to.the.overall.thermal.capacity..
The.minimum.distance.between.the.walls.of.
the. room. and. the. outer. points. on. the. boiler.
(right.and.left.sides.and.rear).must.be.no.less.
than.0.60.m..
It.is.possible.to.place.a.number.of.apparatus.
next. to. each. other,. on. condition. that. all. the.
safety.and.control.devices.can.be.easily.rea-
ched..In.addition,.to.circulate.air.in.the.room,.
air.vents.must.be.made.on.the.outside.walls.
for.which.the.surface.area.must.never.be.less.
than.3,000.cm 2 .and.5,000.cm
density.greater.than.0.8.
The. distance. between. the. boiler. and. any.
fuels. stored. in. the. area. must. be. sufficient.
to. prevent. the. fuels. from. reaching. a. hazar-
dous. temperature,. and. in. no. case. less. than.
4.metres.
2.2 CONNECTION WITH
HEATING SYSTEM
Connections. with. the. heating. system. should.
be.easy.to.disconnect,.made.with.rotating.pipe.
unions..It.is.always.advisable.to.assemble.su-
itable.gate.valves.on.the.heating.system.deli-
very.and.return.pipes..
WARNING:
In order to ensure proper distribution of wa-
ter in the cast iron body, the heating system
delivery and return pipes must be connected
to the same side of the boiler.
The boiler is supplied with connections on
the right side, though they may be moved to
the left side by moving the flanges and their
collars and the corresponding water distri-
butor..
It.is.advisable.to.ensure.that.the.temperature.
difference. between. the. heating. system. deli-
very.and.return.pipes.does.not.exceed.20°C;.
installation.of.a.mixer.valve.with.an.anti-con-
densation.pump.is.advisable.for.this.purpose.
WARNING:
The heating system's circulation pump(s)
must be turned on when the boiler is on.
An automatic precedence system is recom-
mended for this purpose.
The. gas. connection. must. be. made. with. se-
amless.galvanised.steel.pipes.(such.as.Man-
48
nesmann.pipes),.with.threaded,.sealed.joints,.
excluding. three-piece. unions. except. for. the.
start.and.end.connections..
Pipes. must. pass. through. walls. in. a. sealed.
sheath..In.determining.the.size.of.the.gas.pipe.
from.the.meter.to.the.boiler,.take.into.account.
both.rate.of.flow.in.volume.(consumption).in.
m3/c.and.the.density.of.the.gas.in.question..
2 .for.gas.with.a. The. section. of. pipes. in. the. heating. system.
must.be.sufficient.to.ensure.that.the.gas.sup-
ply. fulfils. maximum. demand,. limiting. pres-
sure.drop.from.the.meter.to.any.utility.to.no.
more.than:
–. 1,0.mbar.in.the.case.of.gases.in.the.second.
family.(methane.gas)
–. 2,0.mbar.in.the.case.of.gases.in.the.third.
family.(G30-G31).
On.the.inside.of.the.skirt.is.an.adhesive.plate.
bearing. technical. data. identifying. the. boiler.
and.the.type.of.gas.which.it.is.set.up.to.burn..
2.2.1 Filter on gas pipe
To.prevent.poor.valve.functioning.or,.in.some.
cases,. exclusion. of. the. safety. devices. provi-
ded,.assemble.an.adequate.filter.on.the.gas.
pipe.inlet..
2.3 CHARACTERISTICS
OF WATER SUPPLY
The. water. used. to. supply. the. heating. circuit.
should. must. be. treated. in. accordance. with.
UNI-CTI.8065.standards..
It.is.absolutely.essential.that.the.water.is.to.
be.treated.in.the.following.cases:
–. Very.large.heating.systems.(with.large.wa-
ter.content)
–. Frequent.topping.up.of.water.in.the.system
–. When.the.system.must.be.partially.or.total-
ly.emptied.
2.4 FILLING THE HEATING SYSTEM
It.is.a.good.idea.to.circulate.water.in.the.pipes.
H.on.the.basis.of.total.thermal.capacity:
–.no.more.than.116.kW:.2.00.m
–.from.116.to.350.kW:.2.30.m
–.from.350.to.580.kW:.2.60.m
before.connecting.up.the.boiler.in.order.to.eli-
minate.any.foreign.matter.which.could.affect.
boiler.functioning..
Fill. the. heating. system. slowly. to. permit. air.
bubbles. to. come. out. through. the. outlets. on.
the.heating.system..
The.pressure.at.which.the.heating.system.is.
filled. with. cold. water. and. the. pre-inflation.
pressure. of. the. expansion. tank. must. cor-
respond.to,.and.in.no.case.be.less.than,.the.
height. of. the. static. column. on. the. heating.
system. (for. example,. in. the. case. of. a. static.
column.of.5.metres,.tank.pre-filling.pressure.
and.filling.pressure.must.at.least.correspond.
to.a.minimum.of.0.5.bar).
2.5
The. flue. for. evacuation. of. the. products. of.
combustion. of. natural. draught. boilers. into.
the.atmosphere.must.meet.the.following.re-
quirements:
–. sealed. against. products. of. combustion,.
waterproof.and.heat.insulated;
–. made.of.materials.which.can.resist.normal.
mechanical. stress,. heat. and. the. action. of.
products.of.combustion.and.condensation.
produced.by.them.over.time;
–. vertically. oriented. and. free. of. choking.
throughout.its.length;
–. adequately.insulated.to.prevent.condensa-
tion. or. cooling. of. flue. gases,. especially. if.
located.outside.the.building.or.in.unheated.
premises;
–. separated. from. combustible. or. highly.
flammable.materials.by.an.air.space.or.ap-
propriate.insulation;
–. provided.with.a.chamber.at.least.500.mm.
high. for. collection. of. solid. materials. and.
condensation. underneath. the. entrance. to.
the.first.channel.
. This.chamber.must.be.accessible.through.
an. opening. with. a. metal. door. which. does.
not.let.air.in;
–. circular,. square. or. rectangular. internal.
section;. if. square. or. rectangular,. corners.
must. be. rounded. off. with. a. radium. of. no.
less.than.20.mm;.hydraulically.equivalent.
sections.are.also.permitted;
