Duct Installation; Electrical Installation - AGA Rangemaster FM900 Guide D'installation, D'utilisation Et De Maintenance

The minimum clearance between the top of the hob or
cooker and the bottom of the extractor should be
within the following range (unless a greater distance is
specified by your cooking appliance or
manufacturer):
 Hob-to-extractor minimum clearance distance:
450mm above electric hobs and cookers
750mm above gas hobs and cookers, fryers
760mm above wok burners, griddles, barbeques.
 Hob-to-extractor max recommended distance: 850mm
The minimum distance between the range hob burners
and the bottom of the extractor is essential for safety and
to prevent overheating
components.
The maximum distance between the hob and the bottom
of the extractor is required to ensure that the extractor
collects the cooking fumes and odours efficiently.
Please also note that a 90° bend in the flexible ducting will
require 215mm minimum headroom to give a smooth
radius with no kinking.
SECTION 4. INSTALLATION
Refer to the drawings in Section 8 (Page 10)
The FM built in extractor is designed to slot into a cut-
out/opening made in a horizontal soffit panel (usually the
underside of kitchen furniture or chimney alcove
arrangements).
A panel thickness of at least 15mm must be provided

into which an opening can be made and the unit fixed.
4.1 Prepare Opening
Prepare an opening where the extractor is to be installed.
Product dimensions and general layout are shown in
Section 8 "General Arrangement Drawing" (Page 10) to
help you with this.
Note: Consider and try to build in provisions for accessing
the ducting and top of the cooker hood after it is installed
in your furniture - this may simplify installation and improve
performance by allowing the ducting to be connected and
straightened after the hood is in position and will enable
easier inspection and removal of the unit in the event of
future service need.

4.2 Duct Installation

Make holes, as necessary, in the walls or ceiling to take
the ducting from the extractor exhaust spigot location to
the outside.
Note: A 175mm diameter hole is suitable for both ducting
and electrical cables to pass through.
Depending upon your installation you may need to run the
ducting before or after the extractor is in place, however,
all holes must be made in advance to avoid debris entering
the appliance.
The duct route length should be kept as short as possible
with as few bends as possible (see Section 2).

If terminating on an outside wall a suitable weather louvre
should be fitted. A variety of ducting components and
complete kits are available to suit most installations.
For roof or chimney duct terminations please contact Aga
Rangemaster or seek alternative specialist advice.
 Recirculating Models
We do not recommend recirculating air installations and
they should be avoided wherever possible (see section 2).
If your extractor has been adapted for recirculation (not the
standard configuration) then adequate provision must be
made for exhausted air to return into the kitchen (at least
equivalent to 125mm diameter round duct) - e.g. ducted
out through the top of the cabinet. Failure to do so may
its
cause the unit to overheat and fail and will invalidate your
warranty.

4.3 Electrical Installation

The extractor is a stationary appliance designed to be
connected by fixed wiring to the electrical supply.
ELECTRICAL HAZARD
DISCONNECT ELECTRICAL SUPPLY
BEFORE PROCEEDING FURTHER
A competent electrical technician must perform the
electrical installation.
The hood must be fed from a dedicated 220-240V 50Hz
single phase electrical supply terminated with a
switched spur fitted with a 3A fuse. The spur should be
located adjacent to the extractor/cooker so that the supply
can be disconnected from the extractor using the switch.
The means of disconnecting from the supply must have a
minimum contact separation of 3mm in all poles.
Alternatively, a means of disconnection in the fixed wiring
according to the relevant wiring rules must be fitted.
A supply cord for connecting the spur to the extractor is
included.
The mains supply is connected to the free end of this cord
as follows:

4.4 Connecting the Ducting
Terminate the ducting where it exits the building. If using
a wall mount weather louvre secure the ducting to the
louvre spigot and attach the louvre to the wall. Ensure that
the air fins are directed downwards. If you are fitting an
alternative termination ensure that the ducting is secure.
If using expanding foam make sure that any flexible
ducting is supported internally to prevent it crushing where
foamed.
