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. cur-
rent.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. perfectly. air-vented. rooms..
To.circulate.air.in.the.room,.air.vents.
must. be. made. on. the. outside. walls.
which. satisfy. the. following. require-
ments:
70
–..Have.a.total.surface.area.of.at.least.
2
6.cm
.for.each.installed.Kw.of.ther-
mal. capacity. and. however. not. less.
2
than.100.cm
.
–..To. be. situated. as. close. as. possi-
ble.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. piping. in.
order. to. eliminate. any. foreign. bodies.
that.might.be.detrimental.to.the.oper-
ating. efficiency. of. the. appliance.. 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.connections..
The shutoff valve must be connected
to a suitable flow system and return
pipes
2.2.1
System filling (fig. 4)
The. boiler. and. the. relative. system.
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.
