To change direction, use a T section with an inspection cap to permit
easy access for cleaning inside the pipe. After cleaning, always make
sure that inspection caps are replaced tightly and that their seals are
undamaged and efficient.
2.9.1 Preparation for the condensate drain
The condensate coming out of the drainer must be collected for drip-
ping into a taped vessel connected to the sewer system, if necessary
by interposing a neutralizer (for more information see paragraph "
Neutralization of the condensate"), according to the following proce-
dure:
- Fit a drip tray near the condensate discharge outlet, adding a
condensate neutraliser if necessary
- Connect the drip collection receptacle to the local drain or
sewer system using a siphon.
The drip tray can be created by fitting a cup or simply a polypropyl-
ene bend, suitable for collecting the condensate that comes out of the
appliance and any liquid leaking from the safety valve.
The maximum distance between the condensate drainage of the ap-
pliance and the socket (or socket pipe) must not be less than 10 mm.
The connection to the local drain or sewer system must be executed
using a siphon in order to prevent unpleasant odours from being re-
leased back into the room from the sewer.
We advise using plastic (PP) piping for building the condensate
drainage.
a
Never use copper pipes under any circumstances, as the con-
densate itself will cause them to rapidly deteriorate.
b
Execute the condensate drain outlet so as to prevent combus-
tion gases leaking into the environment or the drain or sewage
system by sizing the siphon (height H) as described in Para-
graph "Discharge of combustion products".
b
Always maintain a slope angle “s” of over 3° and ensure that
the diameter of any condensate drain pipe is greater than that
of the connection fitted at the drain outlet
b
Connect the condensate drain hose to a domestic water drain
in accordance with national and local legislation and stand-
ards.
b
Fill the siphon with water before activating on the thermal mod-
ule in order not to release any combustion products into the
environment when the thermal module is first switched on.
b
It is recommended that condensate from the thermal module
and from the flue should be channelled to the same drain pipe.
b
The connection pipes used must be as short and as straight
as possible. Any curves or sharp bends can lead to hoses be-
coming clogged and, therefore, can prevent proper conden-
sate discharge
b
Size the condensate drain outlet so as to ensure the proper
drainage of waste liquids without leaks
b
The condensate drain must be connected to the drain and
sewage network in such a ways so that the condensate may
not freeze under any circumstances
