Installation recommendations
– We also recommend a distance of at
least 25 ¹/₂" (650 mm) above electric
cooktops to provide more workspace
and easier cooking under the hood.
– When selecting an installation height,
always take the user height into
consideration. Users should have
ample space to work comfortably on
the cooktop and reach the ventilation
hood controls with ease.
– Please note that the greater the
distance from the cooktop, the less
effective the hood is at drawing in the
cooking vapors.
– To achieve optimal vapor extraction,
make sure that the hood covers the
cooktop. The hood should be
positioned centrally over the
cooktop, not to the side or rear.
– The cooktop should be no wider than
the hood. Preferably, it should be
narrower.
– The mounting area must be easily
accessible. The ventilation hood
should be easy to reach and
disassemble in case a service call is
necessary. This should be taken into
consideration when planning the
position of cupboards, shelves,
ceilings or decorative elements in the
vicinity of the ventilation hood.
Drilling diagram for wall
mounting
When drilling, please follow the
directions contained on the
accompanying installation sheet.
When installing a custom back wall
with pre-drilled holes, please refer to
the drilling distances in the drawing
above (screws ³/₁₆" (5 mm)).
* The dimension for the middle wall
bracket is variable. It will depend on the
position of the wall vent and the socket.
It should be set as low as possible.

Installation
29
Plywood backing
The majority of the weight of the
installed ventilation system will be
supported by the lower retaining
plate. It must be firmly attached to
the stud framing behind the drywall.
If studs are not available in the
required locations, a plywood
backing (min. ½" (13 mm) thick)
spanning at least two studs must be
installed.
Failure to adequately support the
weight as stated may result in the
ventilation system falling off the wall,
causing personal injury and property
damage.
If plywood backing is not needed,
proceed to the included "Installation
diagram".
To install a plywood backing
Determine and mark the location of
the retaining plate for the canopy
as outlined on the "Installation
diagram".
Make a cutting line 3" (76 mm) above
and 3" (76 mm) below the outline of
the retaining plate.
Find the studs to the left and right
of the mounting location by tapping
the wall or using a stud finder.
Mark a vertical cutting line along the
center of each stud.
CAUTION: When cutting or drilling
into the wall or ceiling, do not
damage electrical wiring and other
hidden utilities.
Remove the drywall between the
cutting lines and replace it with
plywood of a matching thickness
(min. ½" (13 mm) thick). Tape the
joints and refinish the wall.
Proceed to the enclosed "Installation
diagram" to complete the installation.

Exhaust duct
30
WARNING: Danger of toxic fumes.
Gas cooking appliances release
carbon monoxide that can be
harmful or fatal if inhaled.
To reduce the risk of fire and to
properly exhaust air, the exhaust
gases extracted by the hood should
be vented outside of the building
only.
Do not vent exhaust air into spaces
within walls or ceilings or in attics,
crawl spaces or garages.
To reduce the risk of fire, only use
metal ductwork.
Please read and follow the
"IMPORTANT SAFETY
INSTRUCTIONS" to reduce the risk
of personal injury. Follow all local
building codes when installing the
hood.
Only use smooth pipes or flexible
duct hoses made from non-
flammable materials for exhaust
ductwork.
To achieve the greatest possible air
extraction with the lowest noise
levels, please note the following:
– The diameter of the exhaust duct
should not be less than 6" (150 mm).
– If flat exhaust ducts are used, the
cross section should not be smaller
than that of the exhaust connector.
– The exhaust duct should be as short
and straight as possible.
– If elbows are needed, make sure they
have a large radius.
– The exhaust duct itself must not be
kinked or compressed.
– Make sure that all connections are
secure and airtight.
Remember that any constriction of
the airflow will reduce extraction
performance and increase operating
noise.
If the exhaust duct is to be routed
through an outside wall, we
recommend installing a telescopic
wall vent or a rooftop vent (available
as an optional accessory).
If the exhaust air is to be conducted
into a vent flue, the intake piece must
be aligned with the flow direction of
the flue.
When installing the exhaust duct
horizontally, you must slope it away
from the source by at least 1 cm per
meter (³/₈" per 3 ¹/₄"). This ensures
that condensate cannot drain back
into the ventilation hood.
If the exhaust duct is to be routed
through rooms, ceiling space etc., the
temperatures in these different areas
may differ greatly, which means that
the problem of condensation will
need to be addressed. The exhaust
duct will need to be insulated.

Exhaust duct
31
Condensate trap
In addition to insulating the exhaust
duct, we recommend installing a
condensate trap to collect and
evaporate any condensate which might
accumulate.
Condensate traps are available for
exhaust ducts with a diameter of 5"
(125 mm) or 6" (150 mm).
When installing a condensate trap,
make sure that it is positioned
vertically and, if possible, directly
above the hood outlet duct collar.
The arrow on the housing indicates
the direction of airflow.
Reducing Collar
(optional accessory)
If you would like to reduce the
environmental impact of your ventilation
system by limiting the CFM output the
Reducing Collar can be installed. It
reduces the air flow to less than
400 CFM. Check local building codes
for max. CFM requirements.
Push the Reducing Collar on the
exhaust port of the fan.
Push the exhaust hose over it.
Fix both with a hose clamp.
