Flue gas connection
WerecommendtheuseofELCO’s
comprehensiverangeofuegas
components.
For further information, please see the
installation instructions:
- ELCO wall terminals
- ELCO roof terminals
- ELCOuepipecomponents,both
individualpipesandconcentrictubes.
Regulationsabouttheconstruction
andinstallationofuegassystems
aredi󰀨erentfromcountrytocountry.
Itmustbeensuredthatallnational
regulations with regard to chimney
systemsareobserved.
Notes
Thetablesbelowgiveguidanceon
themaximumlengthsofairandue
gastubesthatmaybeconnected.Ifa
roomsealedinstallationisbeingmade
utilisingseparateairandue
gastubes,thelengthsofbothtubes
mustbeaddedtogetherandnot
exceed the relevant value given in the
tables.
Theradiusofanybendusedintheue
gassystemmustnotexceed87.5°.
Walls that are sensitive to heat
should be insulated.
Construct the ue system in such
way that no recirculation may take
place.
Installation
Connections
Air- / ue gas ducts for individual boilers
Allboilermodelshaveaparallelue
connection.
It is not necessary to install a separate
condensatedrainfortheuegas
system,sincethecondensatewillbe
ushedoutviatheboilerandintothe
siphon.Pleaseobservethefollowing
recommendations:
- Only use corrosion-resistant
material
- Thediametermustbecalculated
and selected according to the
national regulations.
- Thelengthoftheuegassystem
mustbekeptasshortaspossible
(and must not exceed the
maximum permitted length, see the
documentation for planners)
- Horizontaluegastubesmusthave
aninclinationofatleast3°back
towardstheboiler.
Air supply connection
If required, a separate room sealed
airsupplytubemaybeconnected
via the inclusion of the optional air
supplyconnectortting.Thediameter
mustbecalculatedinconformitywith
nationalregulationsandincombination
withtheuegasgassystem.The
overall resistance of the air supply
anduegastubesmaynotexceed
the maximum supply pressure of the
Fan at any time. (Also see the Chapter
“Technical data”)
