If the appliance is located in a recess, then the recess must have adequate
ventilation, we recommend a minimum total vent area of 600 cm².
The stove must be located at least 280mm from any combustible materials.
Timber Frame Construction
Whilst it is possible to install room-sealed appliances in timber frame properties,
great care needs to be taken to ensure that the ue assembly does not interfere
with the weather proong qualities of any outer wall which it may penetrate. Before
attempting this work, further details need to be referenced, (e.g. “Gas Installations
in Timber Frame Buildings” from the CORGI installer series in the UK).
Carport or Building Extension
Where a ue terminal is sited within a carport or building extension, it should have
at least two completely open and unobstructed sides. The distance between the
lowest part of the roof and the top of the terminal should be at least 600mm.
Note: A covered passageway should not be treated as a carport. Flues should not
be sited in a covered passageway between properties.
Basements, Lightwells and Retaining walls
Flue terminals should not be sited within the connes of a basement area, light well
or external space formed by a retaining wall, unless steps are taken to ensure the
products of combustion can disperse safely at all times. It may be possible to install
this Balanced Flue system in such a location provided that it is not sited lower than
1m from the top level of that area to allow combustion products to disperse safely.
Flue terminals should be sited to ensure total clearance of the combustion products
in accordance with the enclosed information.
When the products of combustion are discharged, they should not cause a nuisance
to adjoining or adjacent properties and they should be positioned so that damage
cannot occur to other parts of the building. If the outer wall surface is constructed of
combustible material, a non-combustible plate should be tted behind the terminal
projecting 25mm beyond the external edges of the terminal.

This appliance can be installed in a completely sealed or mechanically ventilated
house without extra ventilation and/or fume extraction.
General Balanced Flue Notes
There are many possibilities for installing this Concentric Balanced Flue system
into a building, both Roof and Wall terminations are possible, and the ue can
either be built into an existing chimney or a completely new ue system may be
constructed.
The system is based upon a Concentric Flue system which utilises an inner ue of
100/130mm diameter which passes through an outer ue of 150/200mm diameter.
The ue gasses that are the products of combustion of the re, pass through the
inner ue and are safely vented to the outside environment. The gap between the
inner and outer ues is the channel by which the stove is supplied with air for
combustion.
These concentric ues terminate outside of the property in a terminal, this terminal
will keep the expelled gasses and the fresh air for combustion separate. It is
important that the terminal is not blocked, a suitable guard maybe required if the
terminal is located at a “Low” level (usually when the terminal is within 2m of oor
level).
The Balanced Flue gas appliance can be installed as an insertion into an existing
or new replace. If an existing Flue or Chimney is to be utilised, then the installation
engineer must be consulted. If the chimney has been previously used it must be
professionally cleaned and certied as being sound and t for use.
The European CE approval on this appliance is restricted to the Flue systems as
specied by the supplier, thus the appliance must only be installed with the original
ue system, no others may be used
The gas re, in combination with the concentric ue system, has been approved
in accordance with the European CE-norm for gas appliances and may therefore
be used only with this system. The guarantee is invalidated if the appliance is
(completely or partially) installed using a different system.
The concentric ue systems can be used with either a newly-built or existing
chimney.
These appliances are designed with the “Firebox” raised up off the ground level by
the built in “Base unit”.
Thus these appliances require no special Hearth arrangements, as the oor will not
get hot and is protected by the steel construction of the “Base unit”.
The appliance must not be tted against a rear wall constructed from a combustible
material; a gap of 300mm should be given all round the stove before combustible
materials may be used in the wall construction.
If the appliance has to be located in an opening, a minimum clearance of 50mm
should be allowed to non-combustible materials.
