instructions, together with the Appliance User Instructions, be left intact with the user.

b) In your own interest, and those of safety, and in accordance with the Gas Safety (Installation

and Use) Regulations 1994, Nestor Martin stoves must be installed by competent persons. Failure

to install the appliance correctly could lead to prosecution.

c) It is important to ensure that the ﬂue system into which the appliance is to be installed is

working properly. Products of combustion which enter a room could be a serious health risk. It is

therefore important, in the interests of safety, that Section 3 of these instructions are strictly followed,

together with the Legal Statues and Codes of Practice listed below.

d) Any unauthorised modiﬁcation will automatically invalidate any guarantee.

e) The installation must be in accordance with the Gas Safety (Installation and Use) Regulations

1994 and with these instructions, and the relevant parts of the Local and National Building Regulations,

and the recommendations of the following British Standards.

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.

E & OE Instructions Part number IN1084 Ed D

13

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.

E & OE Instructions Part number IN1084 Ed D

18

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

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.

E & OE Instructions Part number IN1084 Ed D

20

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.
