tant. 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-

rosion. and. deposits,. the. use. of. inhibi-
tors. such. as. Sentinel X100 or Fernox
Protector F1.is.recommended.after.cle-
aning.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. connec-
ted. to. a. collection. funnel. to. collect. any.
discharge.during.interventions.
WARNING: Failure to clean the heat
system or add an adequate inhibitor
invalidates the device's warranty.
Gas.connections.must.be.made.in.accor-
dance.with.current.standards.and.regula-
tions..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..
System. pipe. sections. must. be. able. to.
guarantee. sufficient. supply. to. cover.
maximum. demand,. limiting. pressure.
loss. between. the. meter. and. any. utility.
device. no. greater. than. 1.0. mbar. for.
second.family.gas.(natural.gas)..

Condensation drain connection
A. siphoned. drain. must. be. connected. to.
the.civil.drain.by.a.pipe.with.minimum.5.
mm.per.meter.gradient.for.condensation.
collection.
Only normal plastic civil drain pipes are
suitable to convey condensation to the
building's sewer drain.

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. device. with. which. the. valve. is.
equipped,. install. an. adequate. filter. on.
the.gas.pipe.

FILLING THE SYSTEM
Cold. system. filling. pressure. must. be. 1
bar..The.system.must.be.filled.slowly.so.
that.air.bubbles.are.released.through.the.
