Foruegasdischarge,refertoStandardsUNI7129-7131.Theuegas
exhaust/air intake kit is not supplied with the boiler as accessories for
sealed-chamber forced-draught appliances, which better adapt to the in
-
stallation context, can be used.
T
o extract the ue gases and restore the combustion air in the boiler,
use original piping or others with the same characteristics which are EC
certiedandensurethattheyarecorrectlyconnectedasindicatedinthe
instructionsprovidedwiththeuegasesaccessories.
Asingleuecanbeconnectedtoseveralappliancesprovidedthatevery

“FORCED OPEN” INSTALLATION (B22-B52)
Theuegasexhaustpipecanbedirectedtothemostsuitabledirection
according to installation requirements.
For installation, follow the instructions supplied with the kit.
Inthisconguration,theapplianceisconnectedtotheø80mmuegas

Inthiscongurationthecombustionairiswithdrawnfromtheroom
where the appliance is installed, which should be technically suita-
ble and ventilated.

SPLIT PIPE OUTLETS (80 Ø)
Twin outlets can be placed in the most suitable direction according to the
room requirements.
The combustion air intake pipe must be chosen from the two inlets (
E and
F );removetheclosureplugxedwithscrewsandusethespecicadaptor
for the chosen input.
The air inlet adaptor Ø 80 (
