General Ventilation Connections - Nibe F110 Installation Manual

General ventilation connections

• Ventilation installation must be carried out in accordance
with current norms and directives.
• Connections must be made via flexible hoses, which
should be installed so that they are easy to replace.
• Provision must be made for inspection and cleaning of
the duct.
• Make sure that there are no reductions of cross-sectional
area in the form of creases, tight bends, etc., since this
will reduce the ventilation capacity.
• The air duct system must be a minimum of air tightness
class B.
• To prevent fan noise being transferred to the ventilation
devices, install silencers in suitable locations in the duct
system.
• For installation with ambient air, the enclosed silencer has
to be fitted in F110.
• Ducts that may become cold must be insulated with diffu-
sion-proof material (at least PE30 or equivalent) along
their entire length.
• Ensure that the condensation insulation is fully sealed at
any joints and/or at lead-in nipples, silencers, roof cowls
or similar.
• A duct in a masonry chimney stack must not be used for
extract air or outdoor air.
• For installation with outdoor air, the air must be routed to
the outdoor air duct through an outer wall grille in the
facade. The outer wall grille must be installed so that it is
protected from the weather and must be designed so that
no rainwater and/or snow can penetrate the facade or
follow the air into the duct.
• When positioning the outdoor air and extract air hood/grille
for outdoor air installation, bear in mind that the two air
flows must not short circuit, thus preventing the extract
air from being drawn into F110 again.
• When positioning the exhaust air and extract air ducts for
installation with ambient air, bear in mind that the two air
flows must not short circuit, thus preventing the extract
air from being drawn into F110 again.
• The heat pump must be provided with the enclosed filter
cartridge (HQ12).
EXHAUST AIR DUCT /KITCHEN FAN
Exhaust air duct (kitchen fan) must not be connected to
F110.
To prevent cooking odours from being led to the F110, the
distance between the kitchen fan and the exhaust air valve
must be taken into consideration. The distance must not be
less than 1.5 m, but may vary between different installations.
Always use a kitchen fan when cooking.

INSTALL THE FILTER CARTRIDGE
The filter cartridge has two sizes of connector, 125 mm or
160 mm.
1. Check the diameter of the air channel for inlet air.
2. When the air duct has a large diameter (Ø 160 mm), the
inner ring must be cut out of the upper section of the
filter cartridge.
3. Cut just inside the inner edge of the outer ring using a
sharp knife. The plastic is prepared for easy cutting.
4. Remove the inner ring.
5. Press the filter cartridge into place in the connection
for incoming air (XL43).
INSTALL THE CONNECTOR
If a filter solution other than that enclosed is used, the en-
closed coupling must instead be mounted in the connection
for incoming air (XL43).
INSTALL THE SILENCER
1. Remove the plugs from the silencer enclosed.
2. Install the silencer in the connection for the outgoing
air (XL44).
