7.3 Connecting the ue gas outlet-/air supply system
XL-boilers can be used both in an “open” and in “closed" system.
Open: The required combustion air is taken from the immediate environment (boiler
room). For this purpose, please comply with the applicable boiler room ven-
tilation regulations BS 6644.
When using boiler category B23 and B33 as an 'open boiler', the protection de-
gree of the boiler will be IPX0D instead of IPX4D.
An air lter must be tted on the air intake of the boiler (available as an acces-
sory with art.nr. AX00540U).
Closed: The required combustion air is sucked in from the outside through a channel.
This improves installation possibilities within a building. In general, outside
air is cleaner than air from the boiler room.
ThefollowinguegasoutletsystemscanbeusedfortheXL-boiler:
- Individualuegasoutlet   Seechapter7.4
- Collectiveuegasoutletunder-pressure Seechapter7.5,7.5.1and7.6
- Collectiveuegasoutletover-pressure  Seechapter7.5,7.5.2and7.6
7.4 Individual ue gas outlet
Optingforanindividualuegasoutletisdeterminedby:
- Favourable position of boilers with regard to outlet area (wall or roof)
- Limited space above the boilers
- Limited number of boilers
Wesuggest youdesign a simpleue gassystem and airsupply system.Forfurther
informationabouttheavailablecomponentsoftheuegasandairsupplysystemwe
recommendyouconsulttheATAGDuopassueliterature.
ATAG supplies the following roof and wall ducts:
RV15RPS0 Roof terminal Ø100 - 150 PP - MZ
RV15WPS0 Wall terminal Ø100 - 150 PP - MW
The ue gas systems described in this document are solely suited forATAG central
heatingboilers.ForthispurposetheCECerticatehasbeensupplementedunderthe
Gastec nr: 0063BQ3021, 0063BT3195 and 0063CM3648.
TheuegassystemshouldbebuiltupusingonlyATAGDuopassprogramproducts.
Combinations with other brands or systems, without permission in writing from ATAG
Heating UK, are not allowed.
When the boiler is operational, it produces a white plume of condensation. This
condensation plume is harmless but may cause some inconvenience, particu-
larly in the case of wall terminal. As a result, roof terminals are preferred.
In a closed installation, roof terminals should be at the same height prevent-
ing ue gas from being sucked in by the other boiler (recirculation). Outlets in
recesses and near erected walls may also bring about ue gas recirculation.
Recirculation has to be prevented at all times.
TheATAGuegassystemismeant,anddesigned,solelyfortheuseonATAGcentral
heatingboilersadjustedtoNatgasorLPG.Themaximumuegastemperaturesare
below 70°C (full load 80/60°C)
Theproperoperationmaybeadverselyinuencedbychangesoforadjustmentstothe
