The Flue
It is possible to remove the top chamber baffle to access the flue for cleaning. However we would advise that
if at all possible an external cleaning access is provided. If the chimney has been lined with the same size
flue as the flue pipe it will be possible to sweep from the flue access point. If the flue is of a larger size than
the flue pipe it may not be possible to use a sweeping brush of adequate size. In which case another cleaning
access will be required. For detailed information see IN1173 The Wood and Mutlifuel Chimney and Installation
Guide.

IMPORTANT
.
The installation of this appliance must comply with all local regulations, including those referring to
national and European Standards before it can be operated. The stove is not suitable for a shared flue.
However, for England and Wales, only, the coming into force on 1st April 2002 of SI 2002 No 440 exempts
the householder from this legal requirement for the installation of solid fuel fired appliance whose rated heat
output is 50kW or less in a building having no more than 3 storeys (excluding any basement) if a Competent
Engineer is employed who is registered under the Registration Scheme for Companies and Engineers involved
in the Installation and Maintenance of Domestic Solid Fuel Fired Equipment operated by HETAS Ltd. These
registered Competent Engineers may also carry out associated building work necessary to ensure that the
installed appliance complies with Building Regulations without involving the Local Authority Building Control
Department.
Improper adjustment, alteration, maintenance or the fitting of replacement parts not recommended by the
manufacturer can cause injury or property damage. Do not operate the stove with faulty seals or damaged
glass.
Due to the high operating temperatures of this appliance it should be located away from pedestrian traffic
and away from furniture and draperies. Do not store paper or wood near the appliance. Any mats and rugs put
in front of the stove should be fire proof and secured to prevent the possibility of tripping.
Advise all persons as to the stove’s high surface temperatures. If it is possible for children or infirm adults to
come into contact with the stove, fit a suitable fire guard.
It is imperative that all air passageways into, out of, and within the appliance are kept clean. All permanent
ventilation into the room provided for the stove must remain clear and unobstructed at all times. Consideration
must be given to the need for extra ventilation if another heating source needing air is to be operated
simultaneously. If an extraction fan is proposed to be fitted to a connecting area of the house, after the stove
has been installed, professional advice should be sought from a qualified engineer.
The user should be advised that the appliance should be inspected regularly and the chimney cleaned at
least annually.
More frequent cleaning may be required and the advice of a qualified chimney sweep should be sought.
Our range of stoves is capable of operating with outstanding efficiency if the flue system is correct. Because
so little heat is wasted to the flue it is possible that moisture within the products of combustion will condense
if the heat losses within the flue way are too great and allow the flue gases to cool. For this reason we
recommend that the stove is fitted with a suitable flue liner, the same diameter as the flue spigot, to prevent
the possibility of acidic damage to the fabric of the chimney and damage to the stove which will reduce the
longevity of the stove.
When correctly installed, the stove is designed to produce heat, safely. It cannot do so if the installation is
less than absolutely stable, constructed of materials suitable for such an installation and consideration has not
been given to the possibility of people with less than ideal common sense operating it.
Have the existing chimney swept by a chimney sweep. Although you will be lining the chimney, any deposits
left in the chimney will cause problems and may become a fire hazard.
Your attention is drawn to the precautions and responsibilities under the Health and Safety at Work Acts,
and whatever new legislation being introduced during the life of this document.

Housing Construction, When Using An Existing Chimney Breast.
Whilst it is almost certain that the fabric of an existing fireplace and chimney will be non combustible and
will have a hearth which conforming to the regulations, it should be inspected to ensure that it has not been
modified by an over zealous “do it yourselfer”.
The depth and width of the fireplace should be measured to confirm there is sufficient room to fit the stove,
before removing any brickwork. Many upper floor chimney breasts house not only the fire place but also the
lower floor chimneys, and the depth is often much less than those of the ground floor.
Before removing any brickwork, the covering plaster should be removed so that any lintels can be identified.
There will probably be two, the first supporting a few courses of bricks above the fire back opening and a
second, higher up, which may be in the form of arched brickwork or a reinforced concrete lintel, which spreads
the weight of the complete chimney structure onto the chimney breast side walls. Removing this lintel without
adequate replacement support may result in a catastrophic collapse of a large area of brickwork. Remove no
brickwork until the main supporting lintel is identified and is confirmed to be sound.
If the main supporting lintel is positioned high enough to accommodate the stove’s housing to give the
required stove position, with the extra height necessary if air ducts are to be fitted, the fire back, surround,
bricks and lower lintel can be removed. If no upper lintel can be observed, its condition is doubtful or it is
found to be too low, a qualified builder should be brought in to install a new lintel. This is not something to be
attempted by anyone without specialist knowledge and experience.
With the fireplace opened to its full size the chimney should be inspected. If the property is very old the cross
sectional area may permit you to instal hot air ducts at the top of the chimney breast or even to extend the
hot air ducts to another floor easily, but as before no brickwork should be removed unless you are experienced
and qualified to understand the implications of modifying supporting structures. To afford the easiest access it
is advisable to fit the flue liner before in filling the fireplace. If the flexible liner is to be lowered from the top,
it is advisable to lower enough flexible liner to allow the rigid to flexible adapter and rigid pipe to be fitted in
relative comfort. Struggling with both arms fully extended into a black void, whilst holding a torch between
you teeth is not the ideal way to ensure this joint is done perfectly which it needs to be if it is to be reliable.

The stove’s flue spigot is fitted to the flue pipe by pushing it upwards from within the stove so that the flue
can be positioned exactly before in filling the fireplace to give the required housing size. A register plate
should now be fitted. This is a plate of metal or a proprietary non combustible board made for this purpose,
which closes all but a hole cut for the flue pipe of the chimney opening. Its purpose is primarily to prevent the
inevitable debre, and especially lime mortar falling onto the stove top, which will cause corrosive damage to
the stove top, but it also serves to position, exactly, the flue pipe in readiness for the stove. If air ducts are to be
attached, holes in the register to accommodate these will need to be added. A secondary lintel will need to be
fitted at the top of the opening into which the stove is to be fitted unless the existing lintel is at the top of the
desired opening.
Before in filling the fireplace, consideration must be given to the heat generated by all the surfaces of the
stove. If the face of the chimney breast is to be a smooth wall the heat surrounding the stove facia may
be sufficient to crack ordinary plaster, especially if it has been applied recently. Heat resistant plasters are
available.
The walls on top of the stove will become very hot and no combustible materials should be used as for any
part of the in filling. Insulating blocks such as “Durarock” may be used to line the cavity if you need to keep
the heat to the fireplace walls at a minimum to protect any pictures that may be hanging on them. Because
the flow of rising hot air from the stove front can be considerable and constantly changing in temperature, no
valuable pictures should be hung above the stove.

If a secondary lintel is to be fitted with only a single thickness of brick to be used as the closure, the inner face
of the bricks should be faced with insulation material to reduce the temperature of the wall face. Rock wool,
fibreglass or several layers of Glasrock are suitable.

Housing construction, without an existing chimney breast.
If the property has no existing chimney or chimney breast the first consideration will be the positioning of the
flue. Taking the flue to the roof internally through the property will involve complying with many regulations
and even an external flue may be subject to planning regulations. Because there will be no existing structural
hearth, this will need to be constructed following the strict Building Regulation requirements. For these reasons
we cannot recommend that anyone without the necessary experience constructs the housing and flue system
for a multifuel insert stove.

Insulating blocks
Because the temperatures reached by the stove’s top and side panels may reach over three hundred
degrees Celsius all materials used for constructing the housing must be both non combustible, stable at high
temperatures and insulate any part of the building which may be affected by heat. It should be born in mind
that insulating materials only limit the rate of heat transference from the heated surface to the unheated
surface and if the dispersal of heat from the unheated surface is less than the rate of heat transference the
entire body of insulating material will reach an almost uniform temperature.

The insulating properties of many modern houses are extremely high and many external walls are now
constructed with an inner skin of plasterboard, supported on a wooden frame which is thermally insulated from
the outer skin of brick. Having such a low thermal conductivity makes it impossible to use the outer wall as the
back of the stove’s housing unless a means of ensuring that non of the heat from the stove is transferred to the
house wall. Whilst this may sound daunting the reward will be a vast increase in heating efficiency.
One solution to the problem is to leave a space between the stove’s housing back and the wall and provide
ventilation to give an air flow between the two. The housing should be constructed with insulating blocks such
as “Durarock” and faced with brick or an insulating board such as “Glasroc” and for extra protection the housing
can be lined with fibreglass or “rock wool” but these should be supported so as not to touch the stove body.
The provision of insulation and air flow will also apply to the heat reaching the ceiling of the room and this will
need extra care if the chimney is to be routed internally through the property.
