UNASSEMBLED.
ASSEMBLY
IS
UNDERTAKEN ON SITE BY THE AUTHORISED AGA
DISTRIBUTOR.
With specific exceptions, the installing of any type of Aga
Cooker is subject to the respective directions contained in
current issue of The Building Regulations. In addition,
Planning Permission may need to be obtained, which
should be applied for separately. The complete range of
Aga cookers are suitable for Natural or Propane gases
only and cannot be used on any other gas.
Cooker Base or Hearth
It is essential that the base or hearth on which the cooker
stands should be level and be capable of supporting the
total weight of the respective cooker.
Models GC and GCB 406Kg, GE and GEB - 584Kg.
The complete cooker is floor-mounted and the space in
which the appliance is to be fitted must have the following
minimum dimensions:-
The top of the hearth must be of non-combustible material
thickness of 12mm.
The wall behind the cooker must be of non-combustible
material for a minimum thickness of 25mm.
A minimum clearance of 60mm is required above the
raised insulating cover handle.
Tiling
When the cooker is to stand in a recess, or against a wall
which is to be tiled, in no circumstances should the tiles
overlap the cooker top plate.
Side Clearances: A 3mm gap is required each side
between the cooker top plate and adjoining work surfaces
that maybe fitted, this is to allow for the safe removal of
the top plate should this be required at a later date.
Installation Requirements
The installation of the cooker must be in accordance with
the relevant requirements of the Gas Safety Regulations,
Building Regulations and the bylaws of the local Water
Undertaking.
It should be in accordance also with any relevant
requirements of the Gas Region and Local Authority.
Where cookers are fitted against side walls a 116mm
clearance is required at the right hand side for oven doors
access. (A further 116mm is necessary if a left hand side
gas connection is required.
If the Aga is to be installed in a brick recess, then the
minimum clearances should be increased by at least
10mm on either side, to allow for the walls not being
square and also for the natural dimensional variations
found in the castings.
In you own interest, and that of safety to comply with the
law, all gas appliances should be installed by a competent
person, in accordance with the relative regulations.
Failure to install appliances correctly could lead to
prosecution.
On completion, test the gas installation for soundness.
In addition a minimum clearance of 1000mm must be
available at the front of the cooker to enable the cooker to
be serviced.
REMEMBER, when replacing a part on this appliance,
use only spare parts that you can be assured conform to
the safety and performance specification that we require.
Do not use reconditioned or copy parts that have not been
clearly authorised by AGA.

AIR SUPPLY
THE HOT WATER SYSTEM
Kitchen or Internal Space Air Supply
(Models GCB and GEB Only)
Where the appliance is to be installed in a kitchen or
internal space, it does not require the kitchen or internal
space containing it to have a permanent air vent.
In a domestic hot water system, the hot water storage
vessel must be of the indirect cylinder of calorifier type.
The hot water storage vessel should be insulated,
preferably, with not less than 75mm thick mineral fibre, or
its equivalent.
Pipework not forming part of the useful heating surface
should be insulated to help prevent heat loss and possible
freezing, particularly where pipes are run through roof
spaces and ventilated under floor spaces. Cisterns
situated in areas which may be exposed to freezing
conditions should also be insulated.
INSTALLATION PIPES
Installation pipes should be fitted in accordance with
current Gas Regulations. Pipework from the meter/tank to
the cooker must be of adequate size, cooker connection
size of 15mm Dia. On completion test the gas installation
for soundness and purge in accordance with current Gas
Regulations.
Draining taps must be located in accessible positions
which permit the draining of the whole system, including
the boiler and hot water storage vessel.
ELECTRICAL
Draining taps should be at least 15mm nominal size. The
use of horizontal pipe runs should be avoided wherever
possible in order to prevent the collection of air in the
system. If horizontal runs are unavoidable, the pipes
should rise upwards in the direction away from the boiler.
Hot water systems should be in accordance with the
relevant recommendations.
A 3Amp 230V~50Hz fused electrical supply is required
adjacent to the appliance. External wiring to the fan unit
must be installed using a 3 core heat resisting 85°C PVC
sheathed cable and in accordance with the current Wiring
Regulations and any local regulations which apply. The
wiring should be completed as indicated:
The method of connection to the mains electricity supply
must facilitate complete electrical isolation of the
appliance, preferably by the use of an unswitched
shuttered socket outlet in conjunction with a fused three
pin plug. Alternatively, a fused double pole switch, having
a contact separation of at least 3mm in both poles, serving
only the appliance may be used.
Water Circulation System
(Models GCB and GEB only)
The cooker boiler should be connected to a cistern water
supply and subject to a maximum head of 18.25m and
minimum 1m.
The 28mm minimum diameter primary flow pipe must rise
continuously from the cooker boiler to the cylinder to
ensure good gravity circulation and have an open vent.
The 28mm diameter primary flow and return pipes must
not exceed 5.5m in length and be well insulated.
Water Connections
(Models GCB and GEB only)
The two 28mm copper flow and return pipes from the
boiler can be obtained for right or left hand connections.
Hot Water Storage Vessel
It is recommended that an indirect 190 litre (40 gallon) hot
water storage cylinder of the double feed type should be
lagged and fixed vertically as near as possible to the
cooker.
The water draw-off pipes to the taps must be dead leg
connection from the vent/expansion pipe.
A drain tap must be fitted at the lowest point of the
system.
Cooker Boiler Heat Exchanger
The heat exchanger must be connected to a 190 litre (40
gallon) copper double feed indirect cylinder.
