a)
precisely measure the thickness of the wall.
This measurement corresponds to the
distance between the flange and the point in
which the duct must be cut
(fig. 15)
b) use a hack saw to cut the aluminium duct to
the specific measurement. Trim off any burrs
using a file
c) insert the duct into the appliance using the
special gasket and tighten it with the three
screws supplied with the kit.
WARNING! The duct can only be connected
in one direction; do not force the pipe if
resistance is felt. Note the position of the
pipe on the flange and turn it in the correct
position, if necessary.
4.4.3 Air heater wall-mounting preparations
and duct installation (appliance with
accessories for separate intake and
exhaust ducts - Installation Type C

)
Unlike the previous solution, to mount the duct
doubling device a recessed housing must be
created in the wall and possibly some chases to
indicate the duct layout
(fig. 16).
Therefore, by positioning the cardboard template,
the centre of the appliance intake/exhaust fitting
must be traced on the wall. The centre of the
similar doubling device fitting must be in the
same position.
Create the depression in the wall for the doubling
device and make the necessary chases to house
the ducts, whether or not they are the rigid or the
