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.

Preparation for the condensate drain
The condensate coming out of the drainer must be collected for
dripping 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 procedure:
− Fit a drip tray near the condensate discharge outlet, add-
ing 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 polypro-
pylene 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 appliance and the socket (or socket pipe) must not be less
than 10 mm.
The connection to the local drain or sewer system must be ex-
ecuted using a siphon in order to prevent unpleasant odours
from being released back into the room from the sewer.
We advise using plastic (PP) piping for building the condensate
drainage.

Never use copper pipes under any circumstances, as the
condensate itself will cause them to rapidly deteriorate.
9
Execute the condensate drain outlet so as to prevent com-
bustion gases leaking into the environment or the drain or
sewage system by sizing the siphon (height H) as described
in Paragraph "Discharge of combustion products".
9
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
9
Connect the condensate drain hose to a domestic water
drain in accordance with national and local legislation and
standards.
9
Fill the siphon with water before activating on the thermal
module in order not to release any combustion products
into the environment when the thermal module is first
switched on.
9
It is recommended that condensate from the thermal mod-
ule and from the flue should be channelled to the same
drain pipe.
9
The connection pipes used must be as short and as straight
as possible. Any curves or sharp bends can lead to hoses
becoming clogged and, therefore, can prevent proper con-
densate discharge
9
Size the condensate drain outlet so as to ensure the proper
drainage of waste liquids without leaks
9
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
