THE CLEAN AIR ACT 1993 AMD SMOKE CONTROL AREAS
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 fixed 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. Further information on the requirements of the Clean Air Act can be found
here:
https://www.gov.uk/smoke-control-area-rules
Your local authority is responsible for implementing the Clean Air Act 1993 including Designation
and supervision of smoke control areas and you can contact them for details of Clean Air Act
requirements. The Nevis Edge 5 has been recommended for burning wood logs in a smoke control
area. The Nevis Edge 5 must be fitted with a permanent stop preventing closure of the secondary
controls beyond 5mm and the tertiary air controls beyond 3mm open.

IMPORTANT INFORMATION ABOUT INSTALLATION AND USING THE STOVE
All national and local regulations, including those referring to national and European standards, need
to be complied with when installing the stove.
The stove must be installed by a registered installer or approved by your local building control officer.
Only use for domestic heating purposes only.
Burn only approved fuels (Wood or manufactured smokeless fuel). Do not use petroleum based
products or use as an incinerator.
This stove will become very hot whilst in operation and due care should be taken. Thick gloves should
be used to operate the primary/secondary controls or reaching inside the stove to position fuel or
remove ash. Do not place flammable objects on or near the stove.
It is possible to fire the stove beyond its design capacity. This could damage the stove, so watch for
signs of overfiring - if any part of the stove starts to glow red, the stove is in an overfire situation and
the controls should be adjusted accordingly. Never leave the stove unattended for long periods without
first adjusting the controls to a safe setting. Careful air supply control should be exercised at all times.
The stove must NOT be installed into a chimney that serves any other appliance and is suitable for
intermittent burning.
Do not make unauthorised changes or modifications to the stove.
The stove and chimney flue must be regularly cleaned. It is especially important to check for blockages
following a prolonged shutdown period. It is recommended that the stove and flue is regularly
maintained by a competent engineer.

INSTALLATION OF THE STOVE
PLEASE READ THESE INSTRUCTIONS CAREFULLY
For your safety it is very important that your stove is correctly installed. Our Stoves cannot accept any
responsibility for any fault arising through incorrect installation or use.
MATERIAL CLEARANCES
The stove must have a minimum clearance to a combustible below.
Fig 4
It is recommended that the stove be installed at least 600mm from combustible materials. However, any
household furnishings should be at least 1000mm away as they could be adversely affected by heat.
If the stove is to be installed in a non-combustible recess it is recommended that 50mm clearance is left at
the back, sides and top for maintenance and to allow air to circulate around the stove to obtain a reasonable
output. A clearance of 150mm will give a better heat output.
Due to the heat of a hot stove, a suitable fire guard should be used to provide additional protection. Never
allow young children to be left unsupervised in a room containing a hot stove.
FLOOR
National and local building regulations must be complied with when considering the floor or hearth where
the stove is to be installed. The floor must be capable of bearing the weight of the stove and the maximum
hearth temperature measured on testing was 111 deg C on full fire.

Nevis Edge 5 Manual (Ref No: S107)
9 CastTec Ltd
THE CHIMNEY
The stove is supplied with a flue pipe connector for top or rear mounting with the fixing screws supplied.
The stove should never be connected to a shared chimney/flue system.
The chimney height and the position of the chimney terminal should conform to Building Regulations.
Minimum chimney height is 4.5m and the recommended minimum diameter is 125mm. The chimney must
be swept before connection to the stove. Check that the chimney is in good condition, dry and free from
cracks and obstructions. The diameter of the flue should not be less than 125mm (spigot diameter) at any
point and not greater than 200mm.
Flue pipes with a smaller cross-sectional area than that of the stove outlet should never be used. Flue pipes
must not project into the chimney connector, such as to cause a restriction to the gas flow.
Consideration must be given to installing extra access in the flue system to ensure all sections can be
cleaned and maintained.
FUME EMISSIONS
To a void ch i mne y pr oble m s, you r fi r e s houl d no t b e b u rnt sl o wly for lo nger th a n 1 2 h o urs wi t hout a pe r i od
of fast burning.
Properly installed and operated, this stove will not emit fumes. Occasional fumes from de-ashing and
refueling may occur. Persistent fume emission must not be tolerated. If fume emission persists, the following
immediate action should be taken:
1. Open doors and windows to ventilate room.
2. Let the fire out or eject and safely dispose of fuel from the stove.
3. Check for flue chimney blockage and clean if required.
4. Do not attempt to re-light the fire until the cause has been identified and corrected.
5. If necessary, seek professional advise.

OPERATING INSTRUCTIONS
THE CONTROLS
The amount of heat emitted by the stove is regulated using the air control built at front of the stove.
using primary air when burning mineral fuel and secondary air when burning wood. The need for de-ashing
the appliance more frequently when burning mineral fuel.
By adjusting the degree to which the primary air and air-wash vents are opened, good control of the
combustion is being established.
The “air-wash” feature when used, should function to effectively keep the inside of the door glass clear of
smokey deposits.
WARNING:
The temperature reached by these items during operation may cause an injury to an end-user.
As these are intended to be adjusted during operation, it is recommended that protective
gloves are wore when handing these parts.
• Push Air Controls to
the right to open.
• Push Air Control to
the left to close.

Nevis Edge 5 Manual (Ref No: S107)

FUEL
This stove will function with wood or manufactured smokeless fuel, but in general all fuel should be dried,
and timber should be well seasoned so as to have a moisture content below 20%. The use of damp wood
will result in more soot and tar deposits being left in the chimney, flue and stove, and will not release heat
if thermal energy is being used to drive out moisture from the fuel.
DO NOT BURN wet or unseasoned wood, construction timber, painted or treated wood, driftwood or
manufactured board products. Doing so will result in the wood burning inefficiently and excess smoke, soot
and tar will be produced. This will coat and damage the internal components of the stove and flue and could
result in a chimney fire.
BEFORE LIGHTING
If using for the first time or following a long period out of use check that the flue is clear and unobstructed.
Check that the ash pan is empty and in position.
WARNING:
During the first few times the stove is used, the heat resistant paint will be curing, and may give off small
amounts of smoke and odours. This is completely normal for this type of appliance, and the room should
be well ventilated.
To aid thi s p roce s s and not d a mag e t h e stov e f inis h , the fir s t f ew time s a n ew sto v e i s use d t h e fire
should be kept to a moderate size, and not fired vigorously.
LIGHTING A WOOD FIRE
1. Place 2 or 3 firelighters or screwed up newspaper onto the fire grate with about 1 kg of kindling and
light the fire with a taper.
2. When the firelighters or newspaper are burning, leave the door ajar about 1 to 2 cm to achieve a
good draw and avoid condensation. Allow the burning kindling to warm up the chimney.
3. After 2 to 5 minutes the chimney should be warm enough create a good draw and the door can be
closed but leave air control open (the control wheel on the door).
4. Once the kindling has formed a good bed of glowing embers the stove can be refueled with 4 or 5
pieces of wood with an approximate size of 200mm by 100mm. (do not be tempted to overfill the
firebox and risk fuel falling onto the glass or out the fire as the door is opened).
WARNING:
When opening the door always open gently for the first 2 to 3 cm to allow the pressure to equalise and
stop smoke from escaping.
The stove should not be operated with either door left open for long periods.
The stove door should never be left open when the stove is in use.
Under normal chimney draft conditions expect to refuel the stove every 45 to 60 minutes.

Nevis Edge 5 Manual (Ref No: S107)
12 CastTec Ltd
REFUELING PROCEDURE
Always refuel onto hot embers. If there is insufficient burning material in the fire-bed to light a new fuel charge,
excessive smoke emission can occur. Refueling must be carried out onto a sufficient quantity of glowing
embers and ash that the new fuel charge will ignite in a reasonable period. If there are too few embers in the
fire-bed, add suitable kindling to prevent excessive smoke.
WARNING:
Directly after re-fueling, It was necessary to operate with the door ajar for a period of 2-3 minutes in
order to maintain flames on the new re-fuel charge.
Do not leave the fire unattended until the flames are well established on the newly charged logs
It is important to follow these instructions in order to achieve clean burning and to maximise the efficiency
of the stove.
The stove must not be overloaded with fuel. Overloading can cause excess smoke, Following the above
procedure will maximise the performance of the stove. Typically, the four logs will burn with an attractive
flame pattern and will last for about an hour (although this will depend on weather conditions, e.g. whether
it is windy, and specific installations, e.g. chimney dimensions)
WARNING:
If there is insufficient burning material in the fire bed to light a new fuel charge, excessive smoke
emission can occur. Refueling must be carried out onto a sufficient quantity of glowing embers and ash
that the new fuel charge will ignite in a reasonable period. If there are too few embers in the fire bed,
add suitable kindling to prevent excessive smoke
The maximum amount of fuel specified in this manual should not be exceeded, overloading can cause
excess smoke.
Operation with the door open can cause excess smoke. The appliance must not be operated with the
appliance door left open except as directed in the instructions.
Operation with the air controls or dampers open can cause excess smoke. The appliance must not be
operated with air controls or dampers door left open except as directed in the instructions

DE-ASHING THE STOVE
Before de-ashing the stove, make sure that all the fuel has burned out and the ashes has cool down, then
use a brush let the ash fall from bed of the fire into the ash pan underneath. Then take out of the ashpan in
this case, if you have a special ash vacuum cleaner, Suck the ash into the vacuum cleaner directly.
If the stove is still burning when you want to de-ash the stove, make sure that you take a heat resistant
glove and use special tools for cleaning. Brush and vacuum cleaner are not suitable in this case.
WARNING
Take g reat care w hen r emov i ng a n d em p tyin g the a sh p a n. It may b e ver y hot and still contain burning
or smouldering embers and is a fire risk.

GUIDANCE ON SAFE OPERATION
FIRE CAN BE VERY DANGEROUS
During operation, the stove and all the fittings (door handles and controls) get very hot.
DO NOT OVER FIRE THE STOVE
It is possible to fire the stove to such an extent that damage may occur. Look out for parts of the stove or
flue glowing red hot. If such a situation occurs adjust the air supply accordingly to reduce the burning rate.
CHIMNEY FIRE
In the event of a chimney fire:
1. Shut all air controls immediately
2. Raise the alarm and evacuate the building
3. Call the fire brigade
4. Do not re-enter the building
FUMES
1. If installed, operated and maintained correctly the stove will not emit fumes into the room other
than occasionally very small amounts when re-fuelling or de-ashing.
2. If fumes are being emitted during normal operation, ventilate the room by opening all doors and
windows.
3. Let the fire burn out
4. Leave the room
5. Check the stove, flue and chimney for blockages
6. Do not re-use the stove until the cause of the problem has been identified and rectified.
7. If required seek expert help.
ADVERSE WEATHER CONDITIONS
In a small number of installations, very occasionally in specific weather conditions (direction of wind) the
draw of the chimney may be affected causing a downdraught and fumes to be emitted into the room.
If this is the case the stove should not be used and advice sought from a professional flue installer who
would be able to advise on possible solutions such as an anti-downdraught cowl.

Nevis Edge 5 Manual (Ref No: S107)

MAINTENANCE
CLEANING
The inside of the stove may require regular cleaning, especially during periods of peak use, the frequency
of this being indicated by experience. it is advisable to wear a dust mask, protective gloves and safety
glasses when cleaning.
Use a stiff brush and industrial type vacuum cleaner to dislodge and remove as much material as possible,
starting at the top of the stove and working down to the bottom. Particular attention should be given to the
air inlet controls which can become obstructed. A CVAC Ash Can filter can vacuum cleaner is ideal for this
process.
GENERAL MAINTENANCE
Take this opportunity to check for any damaged parts inside the stove. In the event of damage or broken
components, replacements can be obtained from your local distributor. On no account should unauthorised
spare parts be used.
The stove and flue way should be inspected and maintained when in a cold condition. No unauthorised
modification of this product should be carried out. This stove requires regular maintenance by a competent
engineer.
STOVE BODY
The stove is finished with a heat-resistant paint which can be cleaned with a soft brush. Wait until the stove
has cooled down before doing this. This finish can be renovated with stove paint from authorised supplier,
although the paint may not be an exact match and it may be necessary to repaint the complete stove/
If the stove is purely ornamental, painting will provide a durable, attractive finish. If the stove is used for
heating, a high temperature heat resistant paint must be used, in either aerosol or brush applied form.
Should rust become apparent, clean thoroughly with a wire brush and apply a suitable anti-rust treatment.
During prolonged periods out of use, the air inlets should be left open and the door left slightly ajar in order
to circulate fresh air and discourage condensation from forming which could encourage corrosion.

Nevis Edge 5 Manual (Ref No: S107)
16 CastTec Ltd
FIRE ROPE
Check the rope around the door and glass, if rope is becoming detached, replace with rope approved for
this purpose.
Inspect the fireproof door seals where fitted, to ensure there is an effective seal around the door and re-fix
it if loose using stove rope adhesive. If in poor condition it should be replaced.
CLEANING THE STOVE
Clean the outside of the stove with a soft brush.
Note that if required the flue can be accessed for cleaning from inside the stove.
STOVE GLASS
Clean any glass panels when cool, avoiding abrasive substances which could scratch the glass and make
subsequent cleaning more difficult. Wet logs against a heated glass, a badly aimed poker or heavy
slamming of the doors could crack the glass panels. The glass will not fracture with heat. Never replace
any broken glass with glass not approved for use with cast iron stoves.
The window glass should remain clean during normal use but it can become blackened if the stove is being
operated with either damp fuels or at a slow burn rate. The blackening may be dispersed by burning firefly
at a much higher temperature, or it may be cleaned off using specialist glass cleaner.
In the event of the glass being broken,it can be removed by unscrewing the retaining clips, taking care not
to damage the fireproof seal. The replacement glass should be carefully placed against the seal and the
retaining clips re-tensioned. Take care to tension these evenly or there is a risk of breaking the new glass
pane.
CHIMNEY
It is important to have the chimney cleaned at least once a year.
Regular inspection and cleaning of the internal components of the stove can indicate if the chimney requires
more frequent cleaning.
If the stove has been unused for an extended period (during the summer) the chimney should be checked
by a competent person before use.
Note:
All parts that are in direct contact with the fire (grate, Baffle, back or side air boxes) are considered as
normal wear parts. Their life will be depended on how vigorously the stove is operated and they must be
inspected and maintained on a regular basis. If they become worn, damaged or not positioned correctly,
non-wear parts such as the stove top and sides will be exposed to excessive heat and may be damaged.
Only use replacement parts recommended by the manufacturer.
