IMPORTANT INFORMATION
Old appliances are not worthless rubbish.
Valuable raw materials can be reclaimed by
recycling old appliances. Before disposing
of your old appliance, render it unusable.
You received your new appliance in a
protective shipping carton. All packaging
materials are environmentally friendly and
recyclable. Please contribute to a better
environment by disposing of packaging
materials in an environmentally-friendly
manner.
The hood can only be used in exhaust air
mode.
Always mount the hood over the center of
the cooking surface.
Minimum distance between electric
cooktop and bottom edge of hood: 30”,
Fig. 1.
The hood must not be installed over a
wood or coal burning stove – a potential fire
hazard (e.g. flying sparks) – unless the stove
features a closed, non-removable cover
and all national regulations are observed.
The smaller the gap between the hood and
cooktops, the greater the likelihood that
droplets will form on the underside of the
hood.
Additional information
concerning gas cookers:
When installing gas cooktops, comply with
the relevant national statutory regulations.
Always comply with the currently valid
regulations and installation instructions
supplied by the gas appliance
manufacturer.
Only one side of the hood may be
installed next to a high-sided unit or high
wall. Gap at least 2”.
Minimum distance on gas cooktops
between the upper edge of the grate and
lower edge of the hood: 30”, Fig. 1.

The exhaust air is discharged upwards
through a duct or directly through the
outside wall into the open.
D
Exhaust air should neither be directed
into a smoke or exhaust flue that is currently
used for other purposes, nor into a duct
that is used for ventilating rooms in which
stoves or fireplaces are also located.
Exhaust air may be discharged in
accordance with official and statutory
regulations only (e.g. national building
regulations).
Local authority regulations must be
observed when discharging air into smoke
or exhaust flues that are not otherwise in
use.
D
When the hood is operated in
exhaust-air mode simultaneously with a
different burner which also makes use of
the same chimney (such as gas, oil or
coal-fired heaters, continuous-flow heaters,
hot-water boilers) care must be taken to
ensure that there is an adequate supply
of fresh air which will be needed by the
burner for combustion.
Safe operation is possible provided that the
underpressure in the room where the burner
is installed does not exceed 4 Pa (0.04
mbar).
This can be achieved if combustion air can
flow through non-lockable openings, e.g. in
doors, windows and via the air-intake/
exhaust-air wall box.
If the air intake is inadequate, there is a
risk of poisoning from combustion gases
which are drawn back into the room.
WARNING – Avoid risk of poisoning – If
the air intake to the room is inadequate,
there is a risk of poisoning from combustion
gases which can be drawn back into the
room.
Note: When assessing the overall
requirement, the combined ventilation
system for the entire household must be
taken into consideration. This rule does not
apply to the use of cooking appliances,
such as hobs and ovens.
If the exhaust air is going to be
discharged into the open, a telescopic
wall box should be fitted into the
outside wall.
PRIOR TO INSTALLATION
Step 1: EXHAUST-AIR MODE
6
For optimum hood efficiency:
❑ Short, smooth duct pipe.
❑
As few bends in the ducting as possible.
❑
Diameter of ducting to be as large as
possible and no tight bends in ducting.
If long, rough exhaust-air ducting,
many ducting bends or smaller pipe
diameters are used, the air extraction
rate will no longer be at an optimum
level and there will be an increase in
noise.
IMPORTANT: The manufacturer of the
hood accepts no liability for com-
plaints which can be attributed to the
design and layout of the ductwork.
❑
Round pipes:
We recommend
Internal diameter: 6”.
❑
Flat ducts must have an internal cross-
section that equates to that of round
pipes.
There should be no sharp bends.

❑
If pipes have different diameters:
Insert sealing strip.
❑
For exhaust-air mode, ensure that
there is an adequate supply of fresh air.
CONNECTING A l 6” EXHAUST-AIR
DUCT:
❑ Mount the duct directly onto the air out-
let on the hood.
Step 2: PREPARING THE WALL
❑ The wall must be flat and perpendicular.
❑
Ensure that the wall is capable of providing a firm hold for mounting screws and
plugs.

Step 3: ELECTRICAL CONNECTION
WARNING: THIS APPLIANCE MUST
BE GROUNDED
The hood should only be connected to a
grounded socket that has been installed
according to relevant regulations.
If possible, site the earthed socket directly
behind the chimney paneling.
❑ The grounded socket should be
connected via its own circuit.
❑ If the grounded socket is no longer
accessible following installation of the
hood, ensure that there is a permanently
installed disconnector.
Step 4: INSTALL ELECTRICAL
SERVICE
Check your local building codes for proper
method of installation. In the U.S., if there
are no applicable local codes, this unit
should be installed in accordance with the
National Electric Code ANSI/NFPA No. 70,
Current Issue. (In Canada, installation must
be in accordance with the CAN 1- B149.1
and .2 - Installation Codes for Gas Burning
Appliances and/ or local codes).
The appliance must be grounded. In the
event of an electrical short circuit, grounding
reduces the risk of electric shock by
providing an escape wire for the electric
current. This appliance is equipped with a
cord having a grounding wire with a
grounding plug. The plug must be plugged
into an outlet that is properly installed and
grounded.
WARNING – Improper grounding can
result in a risk of electric shock.
Consult a qualified electrician if the
grounding instructions are not completely
understood, or if doubt exists as to whether
the appliance is properly grounded.
Do not use an extension cord. If the power
supply cord is too short, have a qualified
electrician install an outlet near the
appliance.
If it is necessary to wire the hood directly
into the mains:
WARNING – Avoid risk of electrical
shock – If the connecting cable for this
appliance is damaged, the cable must be
replaced by the manufacturer or his
customer service or a similarly qualified
person in order to prevent serious injury to
the user.
ELECTRICAL DATA:
Are to be found on the name plate inside
the appliance after removal of the filter
frame.
WARNING – Avoid risk of electrical
shock – Before undertaking any repairs,
always disconnect the hood from the
