a If no chimney is installed, this is the default point of release
in case of refrigerant leakage.
If needed, you can connect a chimney here:
▪ Unit's connection point for the chimney = 1" male thread.
Use a compatible counterpart for the chimney.
▪ Make sure the connection is airtight.

Installation with chimney connected to the outside. The
release height is not relevant. There are no requirements to
the minimum floor area.
N/A Not applicable
Minimum floor area / Release height:
▪ The minimum floor area requirements depend on the release
height of the refrigerant in case of a leakage. The higher the
release height, the lower the minimum floor area requirements.
▪ The default point of release (without chimney) is at the top of the
unit. To decrease the minimum floor area requirements, you can
increase the release height by installing a chimney. If the chimney
leads outside of the building, there are no requirements anymore
to the minimum floor area.
▪ You can also take advantage of the floor area of the adjacent
room (= room B) by providing ventilation openings between the
two rooms.
▪ For installations in technical rooms (i.e. room that is NEVER
occupied by persons), additionally to patterns 1, 2 and 3, you can
also use
PATTERN 4 . For this pattern there are no requirements
to the minimum floor area if you provide 2 openings (one at the
bottom, one at the top) between the room and the outside to
ensure natural ventilation. The room must be protected from frost.
When connecting a chimney
▪ Install the chimney socket (delivered as accessory) to the plate
heat exchanger box.
