3.11 Flue gas discharge and air suction
Observelocallegislationregardinguegasdischarge.
Flue gases are discharged
from a centrifugal fan located inside the combus-
tion chamber and the
control board
constantly checks that this is working
correctly.Theboilerissuppliedwithouttheuegasdischarge/airsuctionkit,
since it is possible to use the accessories for appliance with a forced draught
sealedchamberthatbetteradaptstotheinstallationcharacteristics.
Foruegasextractionandtherestorationofboilercombustionair,itisessen-
tialtoonlyusecertiedpiping.Connectionmustbecarriedoutcorrectlyasin-
dicatedintheinstructionssuppliedasstandardwiththeuegas
accessories.
Multiple appliances can be connected to a single smoke pipe provided that
eachisasealedchamber-typeappliance.TheboilerisaTypeCappliance

“FORCED OPEN” INSTALLATION (TYPE B23P/B53P)
Flue gas discharge pipe ø 80 mm (g. 20)
Theuegasdischargepipecanbedirectedtothemostsuitabledirection
accordingtoinstallationrequirements.Forinstallation,followtheinstruc-
tionssuppliedwiththekit.Inthisconguration,theboilerisconnectedto
theuegasdischargepipe(ø80mm)throughanadaptor(ø60-80mm).
In this case, the combustion air is picked up from the boiler instal-
lation room (which must be a suitable technical room with proper
ventilation).
Uninsulateduedischargeoutletpipesarepotentialsourcesofdanger.
Arrangetheuegasdischargepipesoitslopesby1%towardstheboiler.
The boiler automatically adapts the purging to the type of installation
andthelengthofthepipe.
“SEALED” INSTALLATION (TYPE C)
Theboilermustbeconnectedtoconcentricortwinuegasdischarge
pipesandairsuctionpipes,bothleadingoutdoors.Theboilermust not be
operatedwithoutthem.
Concentric pipes (ø 60-100 mm) (g.21)
The concentric pipes can be placed in the most suitable direction accord-
ing to installation requirements, complying with the maximum lengths in-
dicatedinthetable.

andthelengthofthepipe.
Do not obstruct or choke the combustion air suction pipe in any
way.
