Under the Clean Air Act local authorities may declare the whole
or part of the district of the authority to be a smoke control area. It
is an offence to emit smoke from a chimney of a building, from a
furnace or from any xed boiler if located in a designated smoke
control area. It is also an offence to acquire an “unauthorized
fuel” for use within a smoke control area unless it is used in an
“exempt” appliance (“exempted” from the controls which generally
apply in the smoke control area).
In England, appliances are exempted by publication on a list
by the Secretary of State in accordance with changes made to
sections 20 and 21 of the Clean Air Act 1993 by section 15 of
the Deregulation Act 2015. Similarly in Scotland, appliances are
exempted by publication on a list by Scottish Ministers under
section 50 of the Regulatory Reform (Scotland) Act 2014.
In Wales and Northern Ireland, these are authorised by
regulations made by Welsh Ministers and by the Department of
the Environment respectively.
The Hanbury 4 has been recommended as suitable for use in
smoke control areas when burning wood logs, when operated
in accordance with these instructions and when tted with a
modication that prevents closure of the Secondary Air control
beyond 3.5 mm Open.
The Hanbury 5 has been recommended as suitable for use in
smoke control areas when burning wood logs, when operated
in accordance with these instructions and when tted with a

POSITIONING THE STOVE
It is very important to position the wood stove as close as possible
to the chimney, and in an area that will favour the most efcient
heat distribution possible throughout the house. The stove must,
therefore, be installed in the room where the most time is spent
and in the most spacious room possible. Recall that wood stoves
produce radiating heat, the heat we feel when we are close to a
wood stove. A wood stove also functions by convection, that is
through the displacement of hot air accelerated upwards and its
replacement with cooler air.
The wood stove must not be connected to a hot air distribution
system since an excessive accumulation of heat may occur.
Your stove has been tested to applicable international standards
and therefore can be installed on a suitable non-combustible 12
mm board, sheet or tiles
The oor protector should be of suitable non-combustible board/
sheet or tiles at least 12 mm thick and large enough to extend
under the stove and beyond each side as indicated. These
dimensions also apply if the stove is installed in a recess such as
an inglenook replace.
NOTE: The appliance must be installed on oors with an adequate
load-bearing capacity. If an existing construction does not meet
this prerequisite, suitable measures (e.g. load distributing plate)
shall be taken to achieve it.
FLOOR LOADING CAPACITY
WARNING: Ensure that the load capacity of
the oor is sufcient to carry the weight of the
entire unit, before the stove is installed.

INSTALLATION
Hearths should be constructed of suitably robust materials and
to appropriate dimensions such that, in normal use, they prevent
combustion appliances setting re to the building fabric and
furnishings, and they limit the risk of people being accidentally
burnt.
The hearth should be able to accommodate the weight of the
appliance and its chimney if the chimney is not independently
supported.
Appliances should stand wholly above hearths made of non-
combustible board/sheet material or tiles at least 12mm thick,
if the appliance is not to stand in an appliance recess, or, on a
constructional hearth in accordance with the paragraph below.
CONSTRUCTIONAL HEARTH
Constructional hearths should have plan dimensions as shown in
Diagram A below and be made of solid, non-combustible material,
such as concrete or masonry, at least 125mm thick, including the
thickness of any non-combustible oor and/or decorative surface.
Combustible material should be placed beneath constructional
hearths unless there is an air-space of at least 50mm between
the underside of the hearth and the combustible material, or
the combustible material is at least 250mm below the top of the
hearth. (See diagram B below)

14 6720819898 A 05/2016
FREE STANDING STOVE CLEARANCES
A wood stove must never be installed in a hallway or near a
staircase, since it may block the way in case of re or fail to
respect required clearances. It is of utmost importance that the
clearances to combustible materials be strictly adhered to during
installation of the stove. Refer to the tables below :
• Do not place any combustible material within 1.2m of the front
of the unit.
• The clearance between the ue pipe and a wall are valid only
for vertical walls and for vertical ue pipe.
• The chimney connector must not pass through an attic or roof
space, closet or similar concealed space, a oor, or a ceiling.
• A ue pipe crossing a combustible wall must have a minimum
clearance of 457mm.

CHIMNEY CONNECTOR (STOVE PIPE)
The chimney connector should have a dimension of 125mm which
will t snuggly into the 127mm ue collar of your stove. If this is
not the case, we recommend you contact the dealer in order to
ensure there will be no problem with the draught.
The stove pipe must be made of aluminized or cold roll steel with
a minimum thickness of 0.53 mm. It is strictly forbidden to use
galvanized steel.
The stove pipe should be assembled in such a way that the male
section (crimped end) of the pipe faces down. Attach each of the
sections to one another with three equidistant metal screws. Seal
with furnace cement.
The pipe must be short and straight. All sections installed
horizontally must slope at least 21 mm per meter, with the upper
end of the section toward the chimney. Any installation with a
horizontal run of chimney pipe must conform to local codes.
To ensure a good draught, the total length of the coupling pipe
should never exceed 2.4 m to 3.03 m. Except for cases of vertical
installation, cathedral-roof style where the smoke exhaust system
can be much longer and connected without problem to the
chimney at the ceiling of the room.
Installation of a “barometric draught stabilizer” (replace
register) on a smoke exhaust system is prohibited. Furthermore,
installation of a draught damper is not recommended. Indeed,
with a controlled combustion wood stove, the draught is regulated
upon intake of the combustion air in the stove and not at the
exhaust.

CHIMNEY
In order for the stove to perform satisfactorily the chimney height
must be sufcient to ensure an adequate draught of approximately
15 Pa so as to clear the products of combustion and prevent
smoke problems into the room.
NOTE: A chimney height of not less than 4.5 meters measured
vertically from the outlet of the stove to the top of the chimney
should be satisfactory. Alternatively the calculation procedure
given in EN 13384-1 may be used as the basis for deciding
whether a particular chimney design will provide sufcient
draught. BS EN 15287-1:2007 gives additional details.
The outlet from the chimney should be above the roof of the
building in accordance with the provisions of Building Regulations
Approved Document J.
If installation is into an existing chimney then it must be sound and
have no cracks or other faults which might allow fumes into the
house. Older properties, especially, may have chimney faults or
the cross section may be too large i.e. more than 230 mm x 230
mm. Should remedial action be required, expert advice should be
sought. If it is found necessary to line the chimney then a ue liner
suitable for solid fuel must be used in accordance with Building
Regulations Approved Document J.
Any existing chimney must be clear of obstruction and have been
swept clean immediately before installation of the stove. If the
stove is tted in place of an open re then the chimney should be
swept one month after installation to clear any soot falls which
may have occurred due to the difference in combustion between
the stove and the open re.
If there is no existing chimney then any new system must be to
the designation described above and in accordance with Building
Regulations Approved Document J.
A single wall metal uepipe is suitable for connecting the stove to
the chimney but is not suitable for use as the complete chimney.
The chimney and connecting uepipe must have a minimum
diameter of 125mm and its dimension should be not less than the
size of the outlet socket of the stove.
Any bend in the chimney or connecting uepipe should not
exceed 45°, 90° bends should not be used.
Combustible material should not be located where the heat
dissipating through the walls of replaces or ues could ignite it.
Therefore when installing the stove in the presence of combustible
materials due account must be taken of the guidance on the
separation of combustible material given in Building Regulations
Approved Document J and also in these stove instructions. If it
is found that there is excessive draught in the chimney then a
draught stabilizer should be tted. Fitting of a draught stabilizer
will affect the requirement for the permanent air supply into the
room in which the stove is tted in accordance with Approved
Document J (see also combustion air supply).
Adequate provision e.g. easily accessible soot door or doors must
be provided for sweeping the chimney and connecting uepipe
where it is not intended for the chimney to be swept through the
appliance.
This stove may be connected with a factory built or masonry
chimney with a minimum diameter of 125mm. If you are using
a factory built chimney, it must comply with BS EN 1856-1:2003
standard. It is very important that it is installed according to the
manufacturer’s specications.
If you are using a masonry chimney, it is important that it be built
in compliance with the specications contained in Document J.
The interior diameter of the chimney ue must be identical to the
stove smoke exhaust. A ue which is too small may cause draught
problems, while a large ue promotes rapid cooling of the gas,
and hence the build-up of creosote and the risk of chimney res.
Note that it is the chimney and not the stove which creates the
draught effect; the stove’s performance is directly dependent on
an adequate draught from the chimney.
The following points are important for the installation of the
chimney:
• It must rise above the roof at least 0.9m from the uppermost
point of contact.
• The chimney must exceed any part of the building or other
obstruction within a 3.04m distance by a height of 0.6m.
Installation of an interior chimney is always preferable to an
exterior chimney. Indeed, the interior chimney will, by denition,
be hotter than an exterior chimney, being heated up by the
ambient air in the house. Therefore the gas which circulates will
cool more slowly, thus reducing the build-up of creosote and the
risk of chimney res. The draught caused by the tendency for hot
air to rise will be increased with an interior chimney.
Using a re screen at the extremity of the chimney requires
regular inspection in order to ensure that it is not obstructed
thus blocking the draught, and it should be cleaned when used
regularly. Exterior chimney should be double or triple wall.
CONNECTION TO CHIMNEY
Stoves may have a choice of either a rear or top ue gas
connector that allows connection to either a masonry chimney
or a prefabricated factory-made insulated metal chimney in
accordance with their instructions.
HEATING IN-BETWEEN WINTER SEASONS
Heating the stove, when the outside temperatures are higher, the
ue gases may not be able to escape completely and this may
lead to disturbances in the chimney draught, especially if the
temperatures are rising suddenly. The stove has to be charged
with less wood and then primary air has to be increased so that
the wood can burn down faster (with visible ames) and thus the
chimney ue can stabilize.
REGULAR CLEANING
It is important that the appliance, ue gas connector and chimney
are regularly cleaned and checked for any possible blockages
prior to re-lighting after a prolonged shut down.

FACTORY BUILT CHIMNEY
When a metal prefabricated chimney is used, the manufacturer’s
installation instructions must be followed. You must also purchase
(from the same manufacturer) and install the ceiling support
package or wall pass-through and “T” section package, restops
(where needed), insulation shield, roof ashing, chimney cap,
etc. Maintain proper clearance to the structure as recommended
by the manufacturer. The chimney must be the required height
above the roof or other obstructions for safety and proper draught
operation.

INSTALLATION
Ways of meeting the requirements when proposing factory-made
metal chimneys include:
• Using component systems appropriately designated in
accordance with BS EN 1856-1:2003 to suit the appliance
and installing them in accordance with the relevant
recommendations of BS EN 15287-1:2007
Where a factory-made metal chimney passes through a wall,
sleeves should be provided to prevent damage to the ue or
building through thermal expansion. To facilitate the checking of
gas tightness, joints between chimney sections should not be
concealed within ceiling joist spaces or within the thickness of
walls without proper access being provided.
When providing a factory-made metal chimney, provision should
be made to withdraw the appliance without the need to dismantle
the chimney.
Factory-made metal chimneys should be kept a suitable
distance away from combustible materials. Ways of meeting the
requirements for chimneys designated to BS EN 1856-1:2003
comprise:
• Locating the chimney not less than distance ‘xx’ from
combustible material, where ‘xx’ is dened in BS EN 1856-
1:2003 as shown in the diagram below.
• Where a chimney passes through a cupboard, storage space
or roof space, providing a guard placed no closer to the outer
wall of the chimney than the distance noted above.

USE OF FLEXIBLE METAL FLUE LINERS FOR THE
RELINING OF CHIMNEY
A way of relining an existing chimney would be to use a exible
metal ue liner, appropriately designated in accordance with
BS EN 1856-2:2004 to suit the appliance, fuel and ue gas
characteristics. Flexible ue liners should only be used to reline
an existing chimney and should not be used as the primary liner
of a new chimney.
