• Arrange the exterior air supply from the shadowed side of
the dwelling, preferably from the wall or an overhang. If the
outdoor air is sucked in from under the tiles, it must be en-
sured that no condensation develops in the roof boarding
and no water can run in. Ventilation air can be sucked in
from under the tiles if air can access freely at the top and the
bottom of the roof area and the sewage vent stack does not
end under the tiles.
A = Spacing 10 mm above roof deck
B = Roof insulation
C = Seal with foam
D = Pipe for make-up air to be carefully insulated and provi-
ded with vapour barrier
• Feed the output duct through the roof boarding in such a
manner that no condensation develops in the roof boarding.
• Install the exhaust duct between the Ubiflux and the roof
sleeve in such a manner that surface condensation is pre-
vented.
• Always use an insulated ventilation roof sleeve.

• The maximum permissible resistance in the duct system
is 150 Pa at the maximum ventilation capacity. If the resi-
stance of the duct system is higher, the maximum ventilation
capacity will be lower.
• The location of the mechanical ventilation output and the
sewer stack vent relative to the input must be chosen to pre-
vent nuisance.
• Choose the location of the input valves to prevent fouling
and draught. We recommend to use the Ubbink supply dif-
fusers.
