Condensate drain
If possible, the condensate should be conveyed inside the internal drainage system or pipe. For that purpose, use a
supplied with
pipe of at least 22 mm diameter and a trap with flexible connection the unit to facilitate connection of the
condensate drain pipe.
The pipe must be in glue-joined plastic and not in copper, since the condensate has a pH of 4 (slightly acid).
If the condensate drain pipe cannot be ended on the inside, it is advisable to run it outside as shown in the following
figure.
The pipe sections going to the outside are exposed to the risk of freezing in particularly extreme weather conditions. To
prevent this from occurring, it is advisable to reduce the length of the condensate drain pipes and run them on the inside,
as much as possible, before going to the outside. It may also be necessary to insulate the condensate pipe or apply a
trace heating device to prevent freezing of the condensate.
The pipes outside the building must be in glue-joined plastic with increased diameter of up to 32 or 40 mm with a max-
soakaway
imum run of 3m for connection to a condensate collection or external drain.
soakaway
If using a condensate collection , it must be as indicated in the figure below, or use a specific system (such
as Mc Alpine SOAK1GR) available from the majority of suppliers of products and accessories for plumbing or heating
systems.
