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
-. 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
2
.for.every.kW.
of.thermal.capacity.installed.and.with,.in.
any.case,.a.minimum.of.100.cm
2
.
-. 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 pro-
tected.
2.2
COMPLEMENTARY ACCESSORIES
To. facilitate. connecting. the. boiler. to. the.
system,. the. following. accessories. can. be.
supplied.on.request,.complete.with.instruc-
tions.for.assembly:
-. Installation.plate.code.8075438.
-. Curvette. and. gas. taps/sanitary. water.
output.set.code.8075418.
-. Taps.kit.code.8091806.
-. Kit. of. couplings. for. replacing. wall-hung.
boilers.of.other.makes.code.8093900.
-. Mixed.area.kit.ZONA.MIX.code.8092234.
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. further. informa-
tion,. you. may. directly. contact. SENTINEL.
PERFORMANCE. SOLUTIONS. LTD. or.
FERNOX. COOKSON. ELECTRONICS.. For.
long-term. protection. agains. corrosion.
