Installing The Condensate Hose - Buderus Logano plus GB402 Installation And Maintenance Instructions Manual

6 Fitting
Flue gas routing on multi-boiler systems
(cascade).
These instructions only concern single boiler systems.
Only ask qualified contractors to calculate and size flue
gas / combustion air systems for multi-boiler systems.
Ask the manufacturer of the flue system to confirm and
verify the calculations. The flue gas system must prevent
a return flow of flue gas through boilers that are not in
use.
DANGER: Risk to life from escaping flue gas inside the
installation room!
▶ The gasket in the flue connection of the condensate
pan must be present, in good order and correctly
inserted.
Very different requirements apply to flue connection in different
countries.
NOTICE: System damage through incorrectly drained
condensate.
▶ Drain the condensate generated in the flue via the
boiler flue connection directly into the siphon inside
the boiler ( Chapter 6.2, page 14). Boiler flue
connection, condensate drain and condensate hose
are part of the standard delivery.
▶ Use the boiler flue connection that is part of the
standard delivery.
▶ Plug boiler flue connection [2] into flue connection [1].
▶ Fit condensate hose [3] to the condensate drain of the boiler flue
connection.
▶ Guide the condensate hose through the opening in the lower back
panel.

▶ Make flue connection.
When installing the flue connection, observe the following:
• Country-specific requirements
• The flue pipe cross-section must comply with all current regulations
• Select the shortest possible route for the flue pipe and install it with a
slope towards the boiler.
14
• Secure the flue at appropriate intervals
• Ensure the connection is made free from stress, and that no loads are
transferred to the flue connection.
• During engineering and installation of the flue, create a layout
that best favours the flue gas flow.
DANGER: Risk to life through toxic exhaust gases
escaping.
▶ Check the entire flue system for correctly made and
sealed joints.

Installing the condensate hose

Information regarding the condensate hose.
▶ Carefully drain the condensate created inside the
boiler and flue (route the flue with a slope towards the
boiler).
▶ Drain the condensate generated in the flue via the
boiler flue connection directly into the siphon inside
the boiler. Boiler flue connection, condensate drain
and hose are part of the standard delivery.
▶ Drain the condensate into the public sewerage system
in accordance with the requirements in your country.
▶ Observe regional regulations.
DANGER: Risk to life through poisoning! Open
connections or siphons not filled with water can cause a
through from escaping flue gas.
▶ Filling the siphon with water.
▶ Remove the cap from the filler hole in the siphon supplied and fill with
approx. 2 litres of water.
▶ Fit elbow [4] with inserted gasket onto the filler hole.
▶ Fit the condensate hose from flue system [3] with a hose clip to the
elbow.
▶ Fit the siphon to the outlet on condensate pan [2].
▶ Install neutralising systems (accessories) in accordance with the
installation instructions.
▶ Connect the condensate hose from the siphon with a slope to the
neutralising system.
Where the neutralising system is installed outside the
boiler, there is the option of guiding the condensate hose
through the aperture in the back panel.
