(ATTENTION: the total length of each pipe
should not exceed 25 m, even if the total
loss is below the maximum applicable
loss.)
The.exhaust.pipe.can.be.connected.to.exi-
sting. chimneys.. When. the. boiler. works. at.
low.temperature.is.possible.to.use.normal.
chimneys.at.the.following.conditions:
–. The.chimney.must.not.be.used.by.other.
boilers..
–. The. inside. of. the. chimney. must. be. pro-
tected. from. direct. contact. with. the. boi-
ler.condensation...Combustion.products.
must. be. conveyed. with. a. flexible. piping.
or.rigid.plastic.pipes.with.a.diameter.of.
about. 100-150. mm. providing. so. to. the.
condensation. siphoned. drainage. at. the.
end.of.the.pipe..The.useful.height.of.the.

2.5 INSTALLATION OF SEPARATE
DUCTS TYPE C (ø 80)
This. type. of. exhaust. is. made. with. ø. 80.
polypropylene.accessories.and.without.the.
use. of. gasket. or. sealant. in. type. C. instal-
lation..
The maximum overall length, resul-
ting from the sum of all the suction and
discharge pipes, is determined by the
load losses of the single connected acces-
sories and should not exceed 15 mm H
(ATTENTION: the total length of each pipe
should not exceed 25 m, even if the total
loss is below the maximum applicable
loss.)
See.Table 2.for.information.on.the.load.los-
ses.of.single.accessories.and.the.example.
of.fig..6/a.for.information.on.how.to.calcu-
late.load.losses.

2.5.2 Connection to existing flues
The. ø. 80. exhaust. pipe. can. also. be. con-
nected. to. existing. flues.. When. the. boiler.
runs. at. low. temperature,. it. is. possible. to.
use.standard.flues.provided.that:
O -.. The.flue.is.not.be.used.by.other.boilers.
2
-...The. interior. of. the. flue. is. protected. to.
prevent. a. direct. contact. with. conden-
sation. from. the. boiler.. The. products. of.
combustion.must.be.conveyed.through.a.
flexible. or. rigid. plastic. pipe. around. 100.
to. 150. mm. in. diameter,. and. condensa-
tion. must. be. siphoned. off. at. the. foot. of.
the.pipe..The.usable.height.of.the.water.
trap.must.be.at.least.150.mm.
