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.
Required minimum (ue enclosure) shaft cross-section
Diameterueduct Square shafts Round shafts
100 mm 140 x 140 mm 160 mm
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”)
