Installation Of The Gas Supply
BS 6891
NOTE:
Ensure that the gas supply is capable of delivering the required amount of gas, and is in accordance
with the relevant current standards.
It is generally preferred to conceal the gas supply by bringing it under the hearth, or through masonry
to the rear of the fireplace.
3. Gas Connection
The gas connection to the insert is an 8mm fitting. The maximum length of 8mm pipe leading to the
appliance must be less than 1 meter. Supply pipe to the point of connection to the 8mm must be
of a minimum 15mm or larger as the gas flow rate requires.
4. Appliance Location
a) This insert must be mounted on a non combustible hearth. The hearth must have a
minimum of 12mm non combustible material thickness.
b) The insert is not suitable for installation into a rear combustible wall, any combustible
materials must be removed from an area of 200mm around the installation of the
appliance.
c) There must be a minimum of 200mm from the top of the insert to the underside of any
combustible shelf, Note that for every 50mm increase on clearance, the shelf may
project by a further 50mm.
d) The appliance must not be installed in a room or space which contains a bath or
shower.
e) Any manufactured surround used with this insert should comply with the appropriate
British standard.
f) Do not place furniture or furnishing within 1 metre of the insert.
g) Do not obstruct the area directly beneath the insert as this may block the passage of air
into the appliance.

Housing requirements.
The shaded box shows the absolute minimum housing size required for the Insert gas stove to be
installed where all the housing components are of non combustible materials which remain stable
at high temperatures.
If it is proposed to utilize the optional duct vents (see pages 12 & 19 for further details) the larger
vertical height measurement “B” will be required to allow access for fitting the ducts when the stove
is in its installed position.
If it is proposed to instal the stove in anything other than a brick or cement block housing it will be
necessary to increase the housing size to give a minimum clearance of 200mm after several layers
of “Glasroc” or similar heat proof, insulating material, have been attached to the housing walls.
If the provision of hot air duct outlets are to be utilized, similar care should be taken when routing
the ducts. Although they will never reach temperatures as high as the flue, they will inevitably reach
similar temperatures to the stove body at the point at which they connect with the stove, and although
they will reduce in temperature as the distance from the stove increases precautions should be
taken to insulate them from combustible materials.
The front wall of the housing will be subject to both the heat of the convected air and the radiated
heat from the fire. Although the convected heat will be considerably reduced if the stove is utilizing
its duct vents the front wall will inevitably become very warm. Insulating the inside of the front wall
will reduce the temperature and facing the wall with an insulating material e.g. “Glasroc” will reduce
the temperature even further, but it must never be forgotten that the stove is a heating appliance and
not an animated imitation of the real thing.
Nothing burns without air and the fuel in your stove will require a supply of air. Relying on a natural
ingress of air into the room is often unsatisfactory. By planning for air ventilation as part of the
stove’s installation allows you to position the air inlet where it has the shortest run to reach the stove
which will prevent the occupants being subjected to a draught of cold air.

Flue and Chimney Requirements
BS 5440 : PART 1
Before installation of the appliance, the chimney or flue system must be inspected and passed as
suitable. In particular, the following should be checked:
a) This appliance is suitable for installation onto the following flue types:
A suitable sized diameter flexible or fabricated steel flue system, or a standard masonry
chimney.
(see appliance data for flue size)
NOTE:
Any steel flue systems used should be manufactured in line with the requirements of BS 715, and installed with due
regard to the manufacturers recommendation or any new regulations issued during the life of these instructions.
b) The minimum effective height of the chimney or flue must be 3 metres (10ft) measured
from the hearth to the termination of the flue (chimney pot). If the flue has any non vertical
sections the height should be increased in line with BS 5440 : Part 1.
c) The chimney or flue must be free from any obstruction. Any flue damper or restrictor
must be removed or permanently fixed in the fully open position.
d) The chimney should be swept prior to installation of the stove. However, if the flue is
clean and unobstructed throughout its entire length, it need not be swept.
e) Ensure that only one fireplace is served by the chimney or flue system.
f) Ensure that the chimney or flue system is continuous from inlet to termination.
g) Ensure that the chimney is structurally sound so the combustion products do not come
into contact with combustible materials outside the chimney.
NOTE:
A guide is published by the ‘British Flue and Chimney Manufacturers’ Association’ which
contains general information on chimneys and flues. It can be obtained from:
Sterling House, 6, Furlong, Bourne End, Bucks, SL8 5DG.
h) Installation to a flue pipe system should be in accordance with the flue pipe
manufacturers installation instructions.
IMPORTANT: The flue pipe system should be manufactured in line with BS 715, it should be either a flexible flue liner
or a rigid tubular steel construction, and it must be continuous from appliance outlet spigot to terminal.
IF IT IS INTENDED TO FIT INTO AN EXISTING MASONRY BUILT CHIMNEY SYSTEM
INCLUDING THOSE THAT ARE TERRACOTTA LINED, A SUITABLE DIAMETER FLEXIBLE
FLUE LINER MUST BE USED.
We would not recommend installation without a flexible or other similar liner.
The insert is factory assembled for top flue connection.
i) The flue system may now be connected to the insert, ensure that all joints are sealed
with a suitable fire resistant sealant. It is also recommended that a physical retention
method be used at the flue spigot joint, self tapping screws being favoured.

Insert Construction Methods
This section is a general guide for installing and designing the fireplace or fireplace
surround.
a) The final aperture opening will be dependant on the heat distribution method chosen.
The heat produced by the insert can either be directed completely through the appliance or
partially vented to chamber above the stove and then into the room, or partially vented to
adjoining rooms by vent pipes.
1) Full insert venting to room of installation.
2) Venting by open chamber and insert convection

E & OE Instructions Part number IN1084 Ed D
12
3) Venting by vent tube to alternative locations and through insert to room of installation.
With the use of 100mm (4 inch) flexible
chimney tube, heat can be directed to
alternative locations. These tubes must rise
from the insert to there termination position.
Precautions must be made to prevent heat
directed by these tubes from affecting
inflammable materials.
Brass or steel hit and miss vent covers
can be utilised to control heat output at the
termination position.
CAUTION
The exit point of these vents may become
very hot and precautions should be taken to
prevent injury by guarding. The hit and miss
covers should be designed so that objects
cannot pass into the ducting.

Insert Aperture Construction
The construction of the inserts surround is generally covered by 3 main areas.
A, Adaptation of existing fireplace aperture
B, Construction by modern building practices using non combustible materials
C, Construction of surround in properties with a timber style construction.
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 conforming to the regulations, it should be inspected to ensure that it has
not been modified by an over zealous “do it yourself”.
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 lintle, 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 lintle 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
fireback, 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.

E & OE Instructions Part number IN1084 Ed D
14
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 install 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 infilling the fireplace. If the flexible liner is to be lowered from the top, it is advisable to
lower enough flexible liner to allow it to be fitted to the flue spigot in relative comfort.
The stove’s flue spigot is fitted to the flue pipe by a physical retention method ,self tapping screws
being favoured and sealed with a suitable fire resistant sealant. 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 infilling 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, but facing the chimney breast with a heat resistant plasterboard
such as “glasroc” may well be found to be a more cost and time effective solution.

The walls on top of the stove will become very hot and no combustible materials should be
used as for any part of the infilling. 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. Rockwool or several layers of Glasrock are suitable.

Construction by Modern Building Practices.
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 an insert stove.
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.

Construction of surround in properties with a timber style
construction.
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 “rockwool” 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.

Special Insulation Requirements
The Nestor Martin range of gas inserts are designed to convect the heat produced either to the
room of installation and/or through the heat vent tubes. There are two area`s outside Nestor Martins
Control.
A) Heat radiated from the connecting flue.
B) Heat transfer between stove body and surround construction.
These two hot spots will result in materials used to complete the enclosure above the insert to
become quite hot. The level of temperature will vary greatly with the materials used. In cases where
non insulating materials are utilized we advise that insulation is incorporated as shown (C & D). This
is especially the case where brick or stone is used as a feature. If the surround is to be plain we do
not recommend the use of plaster board.
11. Examples of Materials
British Gypsum can supply a range of frame work, Gyproc metal, and heat resistant materials,
Glasroc,and a full range of jointing and fixing accessories and tools. Information can be obtained
from local builders merchants or from the British Gypsums web site.

Installation of Vent Duct Tubes.
Installing ducts to distribute the heat produced by the stove firstly reduces the temperature of the
stove’s housing and secondly allows other rooms to be heated directly from the stove. This is of
particular benefit if the room in which the stove is to be installed is of less than large size because it
allows the stove to be operated with a larger and more visually interesting fire than would otherwise
be possible without the room becoming unbearably hot.
The lowest grade of flexible flue liner is an ideal choice of material for the ducts themselves and a
wide range of discrete or decorative grills are available for the outlets from builders merchants and
architectural fitting suppliers.
Although the ducts should never
become hot enough to cause a
problem, they should be protected
from any combustible materials.
Where the ducts are to be taken into
other rooms or floors, consideration
should be given to the fact that they
will form a permanent passage for
air to these rooms. If the stove is to
be installed into a property which
has gas appliances the ducts must
be installed with reference to any
applicable gas regulations and no
gas appliance should be operated
in any room to which air is being
ducted, not because the hot air will
cause a problem but because any
gas spillage may find its way into,
and remain, in cold duct work. At
no time should a gas appliance be
operated in the same room as the
stove if the stove is operating with, or
without warm air ducts being fitted.

The Hearth and Fire Surround
Germany has a long tradition of stoves called “Kachelöfen”, which are stoves built into a tiled
structure that acts as a heat store. The insert stove installed within its brick or block housing
will behave in much the same way, using the bricks as a heat store. Although the brickwork will
never become excessively hot it will become very warm if the stove is kept burning at a high
rate. For this reason anything attached to the wall will also become very warm. This may cause
damage to oil paintings and cause accelerated ageing in photographs and we advise you to
restrict the pictures you hang on the walls of the stove housing to those which are of limited
importance.
There has been a revival of interest in all forms of real fires and fire surrounds of every possible
style and material now abound but sadly not all are built to the highest standards or with materials
best suited to the high temperatures they will be subjected to. The minimum distances given
in the drawing below will ensure the surround will be subjected to safe temperatures but it will
not guarantee that a fire surround made from unseasoned wood will not shrink. If stone is to be
used in any part of a fire surround it is important that both the shape and fixings allow for the
stone’s expansion as its temperature rises. Failure to make provision for the uneven expansion
of a fire surround will inevitably result in the stone cracking, in general the stone surround should
comprise of four or more sections.
Minimum distance from extreme of stove front frame to any combustible material is 200mm.
All fire surrounds must be suitable for a real fire.
All stone must have provision for uneven expansion.
A fire guard must be fitted if children or infirm adults are at risk of coming into contact with the stove.
