* Appliance sold without flue/air-inlet ducts.
* The flue gas parts are not part of the boiler. The
boiler is intended to be connected to a separately
approved and marketed system for the supply of
combustion air and discharge of combustion
products.
Condensate is allowed to go to the boiler.
* Air supply inlet and flue gas outlet not at oppo-
site walls

8.4
C63 certified
In general, boilers are certified with their own flue gas material. For type
B23(P), C13, C33, C43, C53 and C83
systems, only use flue gas and air supply parts approved according chapter 4.2.
If a heater is C63 certified, no specific type flue gas material has been certified in combination with the boiler. In this
case the flue gas and air supply parts should comply with the applicable European standards (EN14989).
So, for type C63 systems flue gas and air supply parts from other suppliers can be used. It must be able to handle
the condensate forming (W) and transport, overpressure (P1) and must have a minimum temperature class of
T120
. Also, it has to meet the requirements in the following chapters "air supply" and "flue terminal".
