Connection To A Sealed Flue System - Daikin Rotex GW-20 C22 Instrucciones De Instalación

5.10

Connection to a sealed flue system.

5.10.1 Pipe lengths
As the resistance of the flue tube and air supply pipes increases, the power of the unit will
decrease. The maximum permitted power reduction is 5%.
The resistance of the air supply and the combustible gas outlet depends on the length, diameter
and all components of the pipe system. Per unit category, the total permitted pipe length has been
indicated for the air supply and the combustible gas outlet.

Contact the manufacturer for test calculations for the resistance of the air supply and
combustible gas outlet pipe and the wall temperature at the end of the combustible gas
outlet pipe.

General assembly:
For all outlets, the following assembly applies:
1. Slide the concentric combustion gas outlet pipe and air supply pipe.
2. Slide the concentric pipes into each other.
From the unit, every pipe has to be slid into the previous one.
3. Mount a non-vertical combustion gas outlet pipe on a slope towards the unit
(min. 5mm/m).
4. Fit the assembly brackets in accordance with the assembly instructions of the supplier
of the air supply/flue tube system.
