Connection to a type B23 / B23p chimney

- Abide by prevailing strandards and instructions, particularly the
Order of 27 April 2009 amending the Order of 2 August 1977.
- Particularly the order of 22 October 1969 (FRANCE)
- DTU 24.1 - Flue gas system fittings(FRANCE)
- On traditional installations, the fresh air required for combustion
comes directly from the room in which the boiler has been installed.
- A nozzle is provided for connection to the duct.
- The flue gas duct must be airtight and watertight and must be
constructed in such a way as to allow the discharge of
condensates.
- The horizontal sections need to be constructed with a gradient of 5
mm per metre.
- The chimney must be lined.
- At the lowest points, provide a siphon for the discharge of
condensates.
- By way of an example, the table below gives the dimension L
developed in the flue gas discharge duct according to the
connection diameters and according to concept (see below table).

At each additional elbow of 90° or 45°, subtract the length given in
the following table.

PPS 160 R = D
- With a terrace installation, it is essential to provide two low
ventilation vents diagonally opposite each other in order to prevent
vacuums in the boiler room caused by wind eddies.
