Forced Flue Connection Type C13 And C33 - DeDietrich C 230 ECO Installation And Service Manual

4.6.5

Forced flue connection type C13 and C33

In an installation with a vertical or horizontal forced flue, it is essential
always to ensure that emissions do not trouble the immediate vicinity
of the combustion by-product outlet.
No regular presence of physical persons, height of the emissions
greater than 2 metres, no windows nearby, etc...
Refer to the chapter in the technical manual on the "rule on
installing sealed appliance terminals with a total output of less
than or equal to 70 kW, installed in a boiler room and using gas
fuels".

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.
- By way of an example, the table below gives the dimension L
according to the connection diameters and according to concept
(see below table).
