2.2.2 Sequence/cascade boilers
(fig. 4)
For. sequence/cascade. installations.
using. polypropylene. smoke. collectors.
with. a. clapet. valve,. every. single. boiler.
that.makes.up.the.heating.system.must.
have. the. following. installation. parame-
ters.modified:
-..PAR 1 = 61.(for.G20.NATURAL.GAS.boi-
lers)
-..PAR 1 = 63.(for.G31.PROPANE.boilers)
Refer. to. section. 3.3. to. access. the.
INSTALLER.PARAMETERS.section.
ATTENTION: In sequence/cascade
installations, it is mandatory to arrange
the thermal system with the hydraulic
separator and safety devices.
2.3
CONNECTING UP SYSTEM
To. protect. the. heat. system. from. dama-
ging. corrosion,. incrustation. or. depo-
sits,. before. installation. it. is. extremely.
important. to. clean. the. system. using.
suitable. products. such. as,. for. example,.
Sentinel X300 (new system), X400 and
X800 (old system) or Fernox Cleaner F3..
Complete.instructions.are.provided.with.
the. products. but,. for. further. informa-
tion,.you.may.directly.contact.SENTINEL.
PERFORMANCE. SOLUTIONS. LTD. or.
FERNOX.COOKSON.ELECTRONICS.
For. long-term. protection. agains. cor-
rosion. and. deposits,. the. use. of. inhibi-
tors. such. as. Sentinel X100 or Fernox
Protector F1.is.recommended.after.cle-
aning.the.system..It.is.important.to.check.
the. concentration. of. the. inhibitor. after.
each. system. modification. and. during.
maintenance. following. the. manufactu-
rer’s.instructions.(specific.tests.are.avai-
lable.at.your.dealer)..
The. safety. valve. drain. must. be. con-
nected. to. a. collection. funnel. to. collect.
any.discharge.during.interventions..If.the.
heating.system.is.on.a.higher.floor.than.
the.boiler,.install.the.on/off.taps.supplied.
in.kit.optional.on.the.heating.system.deli-
very/return.pipes..
WARNING: Failure to clean the heat
system or add an adequate inhibitor
invalidates the device’s warranty.
Gas.connections.must.be.made.in.accor-
dance.with.current.standards.and.regu-
lations..

/h.and.gas.den-
sity.must.be.taken.into.account..The.sec-
tions.of.the.piping.making.up.the.system.
must. be. such. as. to. guarantee. a. supply.
of. gas. sufficient. to. cover. the. maximum.
demand,.limiting.pressure.loss.between.
the. gas. meter. and. any. apparatus. being.
used.to.not.greater.than:
–. 1.0. mbar. for. family. II. gases. (natural.
gas);
–. 2.0.mbar.for.family.III.gases.(butane.or.
propane).
An. adhesive. data. plate. is. sticked. insi-
de. the. front. panel;. it. contains. all. the.
technical. data. identifying. the. boiler. and.
the. type. of. gas. for. which. the. boiler. is.
arranged.
2.3.1 Connection of condensation
water trap
The. drip. board. and. its. water. trap. must.
be. connected. to. a. civil. drain. through. a.
pipe. with. a. slope. of. at. least. 5. mm. per.
metre. to. ensure. drainage. of. condensa-
tion.water..
The plastic pipes normally used for civil
drains are the only type of pipe which is
appropriate for conveying condensation
to the building’s sewer pipes.
2.3.2 Filter on the gas pipe
The.gas.valve.is.supplied.ex.factory.with.
an. inlet. filter,. which,. however,. is. not.
adequate. to. entrap. all. the. impurities. in.
the.gas.or.in.gas.main.pipes..
To. prevent. malfunctioning. of. the. valve,.
or. in. certain. cases. even. to. cut. out. the.
safety. device. with. which. the. valve. is.
equipped,. install. an. adequate. filter. on.
the.gas.pipe.

INITIAL PHASE
SYSTEM FILLING
The.charge.pressure,.at.cold.start,.must.
be.1 bar..
The. filling. is. to. be. done. slowly. to. allow.
air. bubbles. to. escape. through. the. air.
vents.
2.4.1 System draining (fig. 5)
To. drain. the. system,. turn. off. the. boiler.
and.use.the.discharge.valve.(1.fig..5).
2.5
EXHAUST
The. boiler. is. supplied. with. a. 80. mm.
gasket,. which. must. be. fitted. over. the.
exhaust. terminal. prior. to. the. flue. being.
installed.(11.fig..6.-.fig..7.-.fig..8).
2.5.1 Type B (fig. 6)
If. the. inlet. is. not. connected,. the. boiler.
should.be.regarded.a.Type B.device..When.
installing. the. boiler. in. locations. where. it.
needs.to.be.protected.from.water,.replace.
the.intake.terminal.inserted.in.the.flange.
with.terminal.code.8089510..
For. information. on. how. to. configure. the.
boiler.in.this.mode.see.figure..6..
The maximum overall length of ø 80
exhaust flues is determined by the load
losses of the single accessories installed
and should not exceed 16 mmH

The. exhaust. pipe. can. be. connected. to.
existing.chimneys..
When.the.boiler.works.at.low.temperatu-
re.is.possible.to.use.normal.chimneys.at.
the.following.conditions:
–. The. chimney. must. not. be. used. by.
other.boilers..
–. The. inside. of. the. chimney. must. be.
protected.from.direct.contact.with.the.
boiler.condensation...Combustion.pro-
ducts.must.be.conveyed.with.a.flexible.
piping. or. rigid. plastic. pipes. with. a.
diameter.of.about.100-150.mm.provi-
ding. so. to. the. condensation. siphoned.
drainage. at. the. end. of. the. pipe.. The.
useful.height.of.the.siphon.must.be.at.
least.150.mm.
2.5.2 Type C (fig. 7 - fig. 8)
The. boiler. becomes. a. Type C device.
when. the. intake. terminal. is. removed.
from. the. flange. and. the. intake. is. con-
nected.to.separate.exhaust.ducts.(fig..7).
or.with.coaxial.exhaust.(fig..8).
2.5.3 Maximum usable length
for separate ø 80 flues
The maximum overall length of ø 80
suction and exhaust flues is determined
by the load losses of the single acces-
sories installed and should not exceed
16 mmH

When. the. segment. of. piping. is. between.
11-16. mm. H

and,. if. needed,. correct. the. maximum.
and. minimum. pressure. adjustment. of.
the.gas.valve.as.specified.in.point.4.2.2.

length for coaxial ø 80/125 flues
In installations with ø 80/125 coaxial
exhaust, the maximum horizontal
