The.boiler.must.be.installed.in.a.fixed.loca-
tion. and. only. by. specialized. and. qualified.
firms. in. compliance. with. all. instructions.
contained.in.this.manual..Furthermore,.the.
installation.must.be.in.accordance.with.cur-
rent.standards.and.regulations.

2.1

INSTALLATION

–..Boilers. can. be. installed. in. all. domestic.

environments. without. any. whatsoever.
limit.in.terms.of.location.and.comburent.
air.supply.

–..These.boilers.can.also.be.installed.in.par-

tially.covered.areas,.as.per.EN.15502,.with.
a.maximum.ambient.temperature.of.60°C.
and. a. minimum. ambient. temperature. of.
-5°C.. It. is. generally. advisable. to. install.
the.boilers.below.weathered.roofs,.on.the.
balcony.or.in.a.protected.niche,.to.protect.
them.from.exposure.to.weathering.agents.
(rain,.hail.and.snow)..All.boilers.provide.a.
standard.antifreeze.function..

2.1.1

Anti-freeze function

The. boilers. are. equipped. with. anti-freeze.
function. which. activates. the. pumps. and.
the. burner. when. the. temperature. of. the.
water. contained. inside. the. appliance. drops.
to. below. 6°C.. The. anti-freeze. function. is.
ensured,.however,.only.if:
-. the. boiler. . is. correctly. connected. to. the.

gas.and.electricity.supply.circuits;

-. the.boiler.is.constantly.fed;
-. the.boiler.ignition.is.not.blocked;
-. the.essential.components.of.the.boiler.are.

all.in.working.order.

In. these. conditions. the. boiler. is. protected.
against.frost.down.to.an.environmental.tem-
perature.of.-5°C.

ATTENTION: In the case of installation in a
place where the temperature drops below
0°C, the connection pipes must be pro-
tected.

COMPLEMENTARY ACCESSORIES

To.simplify.connections.to.the.hydraulic.and.
gas. supplies,. it. is. also. possible. to. use. the.
following.accessories:
–. Mounting.plate,.code.8081220

2.3

CONNECTING UP SYSTEM

To. protect. the. heat. system. from. damaging.
corrosion,. incrustation. or. deposits,. befo-
re. 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.fur-
ther. information,. you. may. directly. contact.
SENTINEL.PERFORMANCE.SOLUTIONS.LTD.
or.FERNOX.COOKSON.ELECTRONICS.
For. long-term. protection. agains. corrosion.
and. deposits,. the. use. of. inhibitors. such. as.
Sentinel X100 or Fernox protector F1. is.
recommended.after.cleaning.the.system..It.
is. important. to. check. the. concentration. of.
the. inhibitor. after. each. system. modifica-
tion. and. during. maintenance. following. the.
manufacturer’s. instructions. (specific. tests.
are. available. at. your. dealer).. The. safety.
valve. drain. must. be. connected. to. a. collec-
tion. 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.delivery/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.accordan-
ce. with. current. standards. and. regulations..
When. dimensioning. gas. pipes. from. the.
meter.to.the.module,.both.capacity.volume.
(consumption).in.m

/h.and.gas.density.must.

be.taken.into.account..
The. sections. of. the. piping. making. up. the.
system.must.be.such.as.to.guarantee.a.sup-

ply. 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.inside.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.condensation.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.devi-
ce. with. which. the. valve. is. equipped,. install.
an.adequate.filter.on.the.gas.pipe.
