Important
Old appliances still have some residual value. An environment-friendly
method of disposal will ensure that
valuable raw materials can be recovered
and used again.
Before you dispose of your old appliance, make sure that it has been rendered
inoperable.
Your new appliance was protected
by suitable packaging while it was on its
way to you. All materials used for this
purpose are environment-friendly and
suitable for recycling. Please make a
contribution to protecting the environment by disposing of the packaging
appropriately.
Up-to-date information concerning options for disposing of your old appliance
and the packaging from the new one
can be obtained from your retailer or
local government office.
Installation of the extractor hood at
a minimum distance of 650 mm (Fig. 1)
is only permissible above a gas hob if
the following rated heat loads (Hs) are
not exceeded:
❑
Gas cookers
load on one burner max. 03.0 kW
load on all burners max. 08.3 kW
load on oven max. 03.9 kW
❑
Gas hobs
load on one burner max. 03.9 kW
load on all burners max. 11.3 kW
❑
Gas glass-ceramic hotplate
The data on nominal heat loads do
not apply to gas glass-ceramic hotplates. Be sure to observe the
instructions provided by the manufacturer of the hotplate.
❑
Solid-fuel cookers
The maximum nominal heat loads
and the minimum distance are the
same as for gas cookers.
The extractor hood can be used for
both exhaust (vented) and recirculation
(ventless) operation.
Always position the extractor hood
over the middle of the hob.
The minimum distance between the
hob and the lower edge of the extractor
hood is 650 mm, Fig. 1.
Additional directions concerning gas
cookers:
Current installation specifications and
directives of the gas appliance manufacturers must be complied with.
Only one side of the extractor hood
should be next to a full-height cabinet
or a wall. Minimum distance: 50 mm.
nstallation of the extractor hood is
I
only permissible over a solid fuel stove
(which may constitute a fire hazard, e.g.
from sparks), provided the solid-fuel
stove has an enclosed, non-removable
cover and national regulations are complied with. This restriction does not
apply to gas cookers and gas hobs.
The closer the extractor hood is to
the hob, the greater the possibility that
rising steam will condense into drops
below the extractor hood.

Before installation
Exhaust air operation, Fig. 2
Exhaust air is discharged upwards
through a ventilation shaft or directly
through the outside wall into the open.
The exhaust air must not be dischar-
D
ged into a functioning smoke or exhaust
flue or into a shaft used for ventilating
rooms in which stoves are located.
When discharging air into smoke or
exhaust flues which are not in use, local
authority approval is required.
When the extractor hood is operated
D
with exhaust air at the same time as fire
installations that require a chimney
(such as gas, oil or coal-fired central
heating systems, instant water heaters
or hot-water boilers), provision must be
made for an adequate supply of air for
stove combustion.
Safe operation is possible if the underpressure in the room where the stove is
installed does not exceed 4 Pa (0.04
mbar).
This can be achieved if the combustion
air can flow through non-closable openings such as in doors, windows, wall
vent-boxes or other technical features
or arrangements whereby combustion
air can be replenished.
Note: In assessing this possibility, the
entire combined ventilation of the home
must be taken into consideration. This
rule does not apply to operation of cooking appliances such as hobs and gas
cookers.
Exhaust air routing must always comply
with local authority regulations.
If the extraction hood is used in recirculating operation - with activated carbon
filter - unrestricted operation is possible.
With exhaust mode, a backwash valve
should be installed unless it is already
incorporated in the exhaust pipe or wall
box. (Fig. 3).
If a backwash valve is not included with
your appliance, your dealer can supply
you with one (see the section on accessories in the operating instructions).
Installation backwash valve:
1. Cut out the protective grid in the air
connector, Fig. 5.
2. Insert the backwash valve in the
mounting openings on the air
connector, Fig. 3.
If the exhaust air is being routed
through the outside wall, a telescopic
wall box should be used, Fig. 4.
Connection between extractor hood
and telescopic wall box:
❑
With an exhaust hose or an exhaust
pipe.
Optimal efficiency of the extractor
hood:
❑
Short, smooth exhaust pipe.
❑
As few bends as possible.
❑
Pipe diameter as large as possible
and wide pipe bends.
❑
Round pipes
we recommend a min. inside diameter of 120 mm.
❑
Flat ducts must have an inside crosssection equivalent to that of the round
pipes.
l 120 mm dia. approx. 113 cm
l 150 mm dia. approx. 177 cm
❑
In the case of different pipe diame-

ters, insert sealing strip.
❑
For exhaust air operation, ensure
that there is an adequate supply of
air.
