The thickness of the sheet metal profi les to connect the discharge
and/or return ducts to the roofcurb are shown in the following
tables:
Note: If the unit incorporates a hot water coil (optional), the length
of the supply duct is reduced by 153 mm.
β
= maximum slope
Important: Check that the roofcurb height is suffi cient to respect
the minimum sealing height required according to local regulations
(example: 150 mm minimum sealing height in France according
to DTU). To do this, check that the “D” dimension of the roofcurb
exceeds the thickness of the cladding plus the insulation plus the
minimum sealing distance required.
