INSTALLATION

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.
current.standards.and.regulations..
2.1 INSTALLATION
-. In.the.rooms.where."type B".boilers.are.
installed,. the. air. required. for. correct.
combustion.of.the.gas.consumed.by.the.
appliance. must. be. able. to. flow. in.. It. is.
therefore. necessary. to. make. openings.
that.cannot.be.blocked.in.the.outer.walls,.
which. must. be. at. least. 6. cm
kW. of. thermal. capacity. installed. and.
with,.in.any.case,.a.minimum.of.100.cm
-. Boilers. are. suitable. for. functioning. in. a.
partially.protected.place,.as.according.to.
EN. 15502,. with. maximum. environmen-
tal. temperature. of. 60°C. and. minimum.
of. -5°C.. We. recommend. installation. of.
these.boilers.under.the.protruding.slope.
of. a. roof,. on. a. balcony,. or. in. a. pro-
tected. niche,. always. providing. they. are.
not.directly.exposed.to.adverse.weather.
(rain,. hail,. snow).. The. boilers. are. . pro-
vided. already. equipped. with. anti-freeze.
functions.
-. In. existing. buildings,. this. natural. intake.
water.heater.must.only.be.connected.to.a.
hot-air.device.shared.by.different.homes.
to. expel. combustion. residues. from. the.
room.where.the.water.heater.is.installed..
The.water.heater.draws.air.required.for.
combustion. directly. from. the. room,. and.
is. equipped. with. a. wind-proof. chimney..
Due. to. poorer. efficiency,. any. other. use.
of. this. water. heater. is. to. be. avoided. as.
it. would. result. in. higher. power. con-
sumption.and.higher.operating.costs.(EU.
REGULATION.No..813/2013).
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,.howe-
ver,.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.
temperature.of.-5°C.
ATTENTION: In the case of installation
in a place where the temperature drops
below 0°C, the connection pipes must be
protected.

2.2 BOILER SUPPORT BRACKET
(fig. 4)
For.the.mounting.of.the.support.bracket.of.
the. boiler,. which. is. supplied,. observe. the.
following.instructions.(fig..4):
–. Fix. the. bracket. to. the. wall. with. appro-
priate.dowels.
–. Check. with. a. spirit. level. that. it. is. per-
fectly.in.horizontal.plane.
–..To.fix.the.boiler.with.the.lives.put.in.evi-
dence.in.figure.
2.2.1 Complementary accessories
To. facilitate. connecting. the. boiler. to. the.
system,. the. following. accessories. can. be.
supplied.on.request:
–. Installation.plate.code.8081217
–. Curvette.kit.code.8075423
.
–. Taps.kit.code.8091833
–. Mixed.area.kit.ZONA.MIX.code.8092234.
For. detailed. information. on. the. assembly.
of. fittings,. see. the. instructions. contained.
in.the.box.
2.2.2 Flow regulator (fig. 5)
In. entrance. of. the. D.H.W.. a. regolator. of.
color.capacity.is.installed.brown;.the.rego-
lator. is. inserted. in. a. bag. to. equipment. of.
the.boiler.
2.3 CONNECTING UP SYSTEM
To.protect.the.heat.system.from.damaging.
corrosion,. incrustation. or. deposits,. before.
installation. it. is. extremely. important. to.
clean. the. system. using. suitable. products.
such. as,. for. example,. Sentinel X300 (new
systems), X400 and X800 (old systems) 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. modifi-
cation. and. during. maintenance. following.
the. manufacturer's. instructions. (specific.
tests. are. available. at. your. dealer).. The.
safety. valve. drain. must. be. connected. to. a.
collection. funnel. to. collect. any. discharge.
during. interventions.. If. the. heating. system.
is. on. a. higher. floor. than. the. boiler,. install.
