If the volume of the installation room is not sufficient the water heater can be connected to ducts with a
diameter 160 mm. If the ducts are not insulated this could generate condensation in the ducts during
operation.
The use of insulated ducts is mandatory.
If the water heater is ducted the parameter setting has to be adapted.
The total pressure drop of ducts and accessories for air intake and exit has to be less than 150 Pa.
The recommended length of ducts has to be respected.
Position of the air intake and exit.
❶ Unscrew the fixing
screws
of
the
air
connection, then turn in
the required direction.
❸ Rotate again by
120°, position to the
opposite sides.
❷ Rotate by 120°,
position to the rear.
A poor duct installation (duct compressed, length or number of bends too high…) can reduce the
performance.
Thus the use of flexible ducts is not recommended.
The ducts can be fitted
directly
on
the
positionable
air
in-
/outlets.
EXIT
Note :
The positionable air connections allow to reduce or avoid the duct bends. For further information on the
positionable air connections, see the § « Positioning of the water heater ».
❹ Do not position the
air connection partially
face to face.
Position not allowed as
cold air will be recycled !
