SECTION 1. INTRODUCTION
During the cooking process, there will be heat, vapours
and fumes produced. Your FM900 built in extractor has
been designed to complement your kitchen both in looks
and performance in order to create a good environment for
creative cooking and is ideal for applications where a
conventional cooker hood is neither suitable nor desirable,
for example, in an inglenook chimney or kitchen furniture
above the hob.
SECTION 2. EXTRACTION PERFORMANCE
The most important influence on the performance of the
extractor is the design of the ducting which takes the
exhaust air from the extractor to the outside wall louvre.
The duct route should be a prime consideration during the
initial stages of the kitchen design (We do not recommend
recirculating air back
recirculating carbon filter conversion kits are available if
absolutely necessary).
Please note the following:
 Easy access to the duct route during installation is
important. Lack of access may require the "blind" fitting
of flexible ducting, with increased risk of unseen kinks
and impaired efficiency.
 The extractor is provided with a spigot suitable for
connecting 150mm diameter duct.
 150mm is the minimum duct diameter consistent
with efficient extraction. Smaller ducting must not
be used.
 The exhaust duct route length should be kept as short
as possible (≤ 5m) with as few bends as possible.
 The most efficient configuration is to duct straight
through an outside wall so try to position the cooker
against an outside wall when designing your kitchen
layout.
 Well installed, correctly sized rigid round ducting (or an
equivalent flat channel system) will usually perform
best, with round semi-rigid (like flue liner) being a very
good alternative. Flexible (foil or plastic film) ducting is
economical but its use should be minimised as it gives
the worst performance and should only be used for very
short duct runs or initial connection and should be
pulled taut to prevent significant losses in extraction
efficiency.
 A route with more than two 90° bends will significantly
degrade the performance of the extraction system. If
possible, avoid having a 90° bend at the extractor
exhaust spigot; keep bend radii as large as possible to
maintain a smooth airflow without vortices; avoid kinks
in flexible ducting; pull flexible ducting taut over straight
runs to ensure that the internal surface is as smooth as
possible.

 If using rigid ducting, we recommend that the initial duct
connection to the extractor spigot is made using semi-
rigid round ducting to allow for any positioning errors
and easy disconnection in the event of maintenance.
SECTION 3. IMPORTANT INFORMATION
Requirements of the relevant authorities concerning the
discharge of exhaust air must be complied with.
The exhaust air must not be discharged into a flue
which is used for exhausting fumes from appliances
supplied with energy other than electricity, e.g. oil or
gas-fired central heating boilers, gasfired water
heaters, etc.
Adequate ventilation of the room must be provided
when the cooker, extractor and appliances supplied
with energy other than electricity (e.g. gas-fired or oil-
fired heaters, etc.) are used simultaneously. The room
must be provided with vents to allow a constant flow of
fresh air.
Pay particular attention to fire risk when frying. To
minimise the risk of fire, all instructions relating to
cleaning the grease filters and removing grease
deposits must be adhered to.
Do not flambé under the extractor.
Proper care must be taken to ensure that the negative
pressures caused by high performance extraction
systems do not adversely affect the safe operation of
certain types of fuel-burning appliances (gas, oil or
solid fuel), including those installed in the kitchen and
possibly also those installed in other parts of the
house.
Where such fuel-burning appliances are installed,
adequate ventilation MUST be provided in the room of
installation, located and sized such that the negative
pressure in the room created by the extractor does not
exceed 4Pa.
In case of doubt, do not operate the extractor and fuel-
burning appliance(s) simultaneously and consult an
appropriate (for the fuel type) expert for advice.
ATTENTION
This appliance requires an earth connection.
Ensure that the supply voltage corresponds to that
marked on the rating label inside the extractor.
The extractor must be isolated from the electrical
supply before carrying
maintenance operations.
