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.
Inallcases,theconcentricue/air
connection on the top of the boiler
case is 80/125. When using 110/150
uecomponents,anallowancefor
the necessary 80/125 to 110/150
adaptorttinghasbeenincludedin
theuelengthsindicatedinthetables.
The maximum length of any external
sectionofuepipemustnotexceed
5m.
Theradiusofanybendusedintheue
gas system must not exceed 87.5°.
Installation
Connections
Air- / ue gas ducts
All boiler models have an ø80/125
concentricueconnection.
Required minimum (ue enclosure) shaft cross-section
Diameterueduct Square shafts Round shafts
80 mm 120 x 120 mm 130 mm
110 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”)
