Instructions Installing the duct system
It is important that you insulate the duct system
correctly in order to avoid heat loss. Where the
design allows, the ducts can be run in/under the
insulation without any problems and this will
save some of the costs of insulation.

covered by at least 100 mm of insulation
and that the insulation is fixed tightly around
the duct.

have at least 30 mm of insulation to protect
against condensation. Where there is a pre-
heating surface or a geothermal surface, the
insulation of the fresh air intake should be at
least 100 mm.

dampers, as they already have
50 mm of insulation.
In order to minimise heat loss from the duct sys-
tem in the ceiling, both the supply and discharge
ducts should be insulated using at least 100 mm
of insulation.
If you use insulation option A, we recommend
using two layers of 50 mm paper or foil covered
lamella mat mounted with staggered joints.
You should also note that if you use steel wire to
tie on the insulation, you must not tighten the
steel wire so much that it deforms or breaks up
the insulation.

The above should be considered recom-
mended values only and you must always
abide by any country-specific regulations.
