Phil Green & Son Aga Site Preparation

Site preparation details for Oil Aga Range
Cookers
Flue Arrangements: All of our reconditioned Aga
Range Cookers require a conventional or open flue,
i.e. a chimney. This can either be in the form of an
existing brick chimney or by installing a pre fabricated
flue system.
Current legislation requires that any flue installation is
subject to building regulations and planning, or it
must be installed by an OFTEC qualified and
registered engineer, who is therefore not required to
apply for local authority permission.
Each flue installation requires the appropriate
documentation usually in the form of a data plate
located at the electric
specification, location, with the installers name and
address plus the date of the installation.
Our engineer will need to verify the presence of a flue
data plate prior to any appliance installation.
Existing Brick Chimney: An existing brick chimney
needs to be lined with a 125mm flexible flue liner to
BS 715. The chimney will need to be swept prior to
installation of the liner. This also applies to chimneys
built using clay liners or flue blocks.
As the term chimney liner implies it is for use only
within the confines of an existing chimney and should
not be used outside these confines.
A 125mm to 100mm reducer will be required where
the liner joins the 100mm vitreous flue pipe from the
Aga Range Cooker.
Flue connections to Aga Range Cooker: The flue
can be connected to exit either vertically from the top
of the flue box or horizontally from the rear of the flue
box. Where the flue is to exit vertically from the Aga
Range Cooker there must be a minimum of 600mm
of vertical pipe prior to any bends and these bends
should be no greater than 45 degree. Basically the
liner or pre-fabricated flue should enter the room as
high as possible enabling the first bend in the flue to
be a minimum of 1600mm above the level of the

plinth.

Where the flue is to exit horizontally from the rear of
the flue box the horizontal run should be as short as
possible.

In situations where it is unable to provide the 600mm
of vertical rise from the top of the flue the Aga Range
Cooker can be brought forward from the back of the
wall allowing the use of the rear exit.
Special attention should be given to the diagrams
detailing the flue box dimensions.
For instance despite popular thought the flue is not in
centre of the Aga Range Cooker.
The Aga Range Cooker uses 100mm vitreous flue
pipe, which is then adapted to the 125mm flue by a
reducer.
Plinth: The cooker should be positioned on a level
base of non-combustible material, i.e. concrete/slab.
The plinth width for a 2 oven Aga Range Cooker is
987mm The plinth width for a 4 oven Aga Range
Cooker is 1490mm The depth for a Delux Aga
Range Cooker is 690mm The depth for a Traditional
is 670mm
The height of the plinth is optional but is usually no
less than 50mm, which brings the top plate of the
Aga Range Cooker to a normal 900mm work top
height.
Important: The plinth should be positioned with the
position of the flue in mind remembering that the flue
centre line is 470mm from the right hand edge of the
plinth.
Pre-Fabricated Flue Systems: In the absence of an
existing chimney a pre-fabricated flue can be used to
run either within the fabric of the building or
externally.
Flue should be 125mm double skinned insulated
such as K vent or LTZ.
In exposed situations where the majority of the flue
run is external it may be advisable to use a higher-
grade flue such as Selkirk or SMZ or SMW.
When using a pre-fabricated flue it is important to
ensure the flue will terminate above the ridge of the
roof in a similar position to existing chimneys. A flue
terminating above guttering will possibly be subject to
downdraught and therefore be useless.
advisable to sort out such problems at the design
stage, usually by locating the appliance in a more
suitable position ie against the gable end where a
