ATTENTION!
Step 3 of Fig.17 shows how to fit the terminal duct from
inside the room where access to the outside wall is not possible. Such
a sliding operating can be done providing that the optional wall liner is
used. (This is required to seal any cavity and to allow the sealing ring to
pass through from inside and provide an adequate external seal). The
wall liner is a tube of 130 mm diameter with a wall thickness of 0.8 mm.
This step may be skipped where outside wall is accessible and the ter-
minal duct can be pushed through the wall from outside. In this case, an
adequate smaller hole can be drilled on the wall to be able to pass the
Ø100 mm terminal duct.
4.2.6 Installing the Flue System with Straight Extension Kit:
In case the total length required for a straight outlet from the wall is more
than 725 mm, 500 and/or 1000mm extension kits should be used with
the standard kit. Refer to Fig. 18.
