INSTALLATION
2.1
BOILER ROOM
The. boilers. with. a. rating. of. more.
than. 35. kW. must. be. equipped. with.
a.technical.room.whose.dimensions.
and.requirements.correspond.to.the.
current.standards.and.regulations..
The.minimum.distance.between.the.
walls. of. the. room. and. the. boiler.
must.not.be.less.than.0.60.m.,.while.
the. minimum. height. between. the.
top. of. the. boiler. and. the. ceiling.
must. be. at. least. 1. m..which. can.be.
reduced. to. 0.50. m.. for. boilers. with.
incorporated. heaters. (however. the.
minimum. height. of. the. boiler. room.
must.not.be.less.than.2,5.m)..
The.boilers.with.a.rating.of.less.than.
35. kW. can. be. installed. only. in. per-
fectly.air-vented.rooms..
To.circulate.air.in.the.room,.air.vents.
must. be. made. on. the. outside. walls.
which. satisfy. the. following. require-
ments:
–..Have. a. total. surface. area. of. at.
2
least.6.cm
.for.each.installed.Kw.
of. thermal. capacity. and. however.
not.less.than.100.cm
68
–..To.be.situated.as.close.as.possible.
to. the. floor,. unobstructable. and.
protected. by. a. grate. which. does.
not.reduce.the.air.passage.area.
2.2
CONNECTING UP SYSTEM
Before. proceeding. to. connect. up.
the.boiler,.you.are.recommended.to.
make.the.water.circulate.in.the.pip-
ing.in.order.to.eliminate.any.foreign.
bodies.that.might.be.detrimental.to.
the.operating.efficiency.of.the.appli-
ance.. For. connecting. up. the. pipes,.
make. sure. to. follow. the. indications.
illustrated.in.fig..1..The.connections.
should. be. easy. to. disconnect. using.
pipe.unions.with.orientable.connec-
tions..

.
The. boiler. and. the. relative. sys-
The shutoff valve must be
connected to a suitable flow
system and return pipes
tem. must. be. filled. operating. on.
the. bearing. tap. and. the. pressure.
of. cold. charging. the. system. must.
be. included. between. 1-1.2 bar (98-
117.6 kPa)..
During.filling.the.main.switch.should.
be.left.open..
Filling.must.be.done.slowly.so.as.to.
allow. any. air. bubbles. to. be. bled. off.
through.the.provided.air.vents..
This.operation.can.be.made.easy.by.
positioning. horizontally. the. incision.
of. the. block. screw. of. the. shutoff.
valve..
Upon.completing.the.filling,.put.the.
screw.back.to.its.original.position..
At. the. end. of. the. operation. make.
sure.that.the.tap.is.closed.(fig..4).
