Concentric connector
Maximum length concentric tubing:
6 metres due to the maximum air temperature at the venturi (70°C).
Note:
- A 90 degree bend = 1 metre equivalent length.
Example:
- 6 metres concentric = one 90° bend + 4 metres hori
outlet 1 metres.
“CE” approved according to EN 483
A drain outlet must be provided near the boiler to
prevent condensation from the chimney entering the
boiler.
All horizontal pipe runs must fall to the boiler to prevent
condensation water escaping from the terminal.

Sample calculation
The diagram below consists of the
following parts (Ø 80 mm) :
• 1 x Pipe bend 90°
• 2 x Straight pipe L 2000 mm
• 2 x Pipe bend 45°
• 2 x Straight pipe L 1000 mm
• 1 x Vertical terminal
• 1 x Condensation drain vertical
Calculation:
• 1 x 4,32 = 4,32
• 2 x 5,1
= 10,2
• 2 x 2,75 = 5,50
• 2 x 2,55 = 5,10
• 1 x 5,4
= 5,4
• 1 x 2,06 = 2,06
Total:
32,58 x 2 = 65,16 Pa
This value is less
than the maximum
authorised resistance,
therefore the installation
is compliant.
A condensation drain outlet must be fitted close to the
boiler to prevent condensation products from the
chimney running into the boiler.
