Some types of fire cement are caustic and should not be allowed to come into contact with the skin. In case of contact
wash immediately with plenty of water.
PREPARATORY WORK AND SAFETY CHECKS
IMPORTANT WARNING
This stove must not be installed into a chimney that serves any other heating appliance. There must not be an extractor
fan fitted in the same room as the stove because this can cause the stove to emit fumes into the room.
Asbestos
This stove contains no asbestos. If there is a possibility of disturbing any asbestos in the coarse of installation then please
seek specialist guidance and use appropriate protective equipment.
Metal Parts
When installing or servicing this stove care should be taken to avoid the possibility of personal injury.
CO Alarms:-
Building regulations require that when ever a new or replacement fixed solid fuel or wood/biomass appliance is installed
in a dwelling a carbon monoxide alarm must be fitted in the same room as the appliance. Further guidance on the
installation of the carbon monoxide alarm is available in BS EN 50292:2002 and from the alarm manufacturer’s
instructions. Provision of an alarm must not be considered a substitute for either installing the appliance correctly or
ensuring regular servicing and maintenance of the appliance and chimney system.
Stove paint Aerosols
Paint aerosols are flammable and therefore dangerous to use around a lit stove. Be sure to allow aerosols spray paints
to dry and ventilate the room well before lighting the stove. The use of any aerosol around lit stove is dangerous and
care must be take in handling aerosols.
IMPORTANT:
These instructions cover the basic principles to ensure the satisfactory installation of Mendip Stoves

4. INSTALLATION
Your flue and chimney
For your stove to work properly the chimney must also work properly. Check out the following points whilst bearing in
mind that this is for informational purposes only and is not binding for us in any manner whatsoever. It is an unfortunate
fact that there are numerous factors that can play decisive roles in the correct functioning of a chimney.
� Thoroughly clean your chimney prior to installation. If it has not been used for a long time, ask a specialist to inspect
it.
� The chimney should be of sufficient height to guarantee a minimum draw of 8-20 Pascal. It is only possible to measure
the chimney draught while the appliance is working. If the draw is insufficient raise the chimney and/or insulate it. If
the flue draught is too great you will need to install a draught regulator.
� The flue should, ideally, be vertical and not change direction at any more than 45º from vertical.
� The flue should not join into another. It should be separate throughout its entire length and have its own, separate
chimney pot.
� The flue should be free of obstructions, of the same size throughout and preferably round. The size should be that
specified for the stove to function correctly (see catalogue).
� If the top of the chimney is within 60cm of the ridge of the roof, or closer, it should project at least 60cm above the
ridge. Elsewhere on the roof, not close to the ridge, the chimney should be at least 1 metre above the roof, measured
from the upper side.
� The chimney should not be close to tall trees, walls or buildings as these could cause down draughts.
� The chimney must be well insulated. The internal face of the flue must be free from cracks and fissures and lined with
fire cement or other, suitable, refractory material. If not, then a suitable liner must be installed throughout its entire
length.

12
Lining Your Chimney
European standards must be followed. Due to the technical nature of these standards they are mostly intended for
professional installers. The following lists the relevant European standards.
EN 12446: 2003 - Chimneys - Components - Concrete outer wall elements
EN 1443: 2003 - Chimneys - General Requirements
EN1856-1: 2003 - Chimneys - Requirements for metal chimneys - Part 1: Products for system chimneys
EN1856-2: 2004 - Chimneys - Requirements for metal chimneys - Part 2: Metal liners and connecting flue pipes
EN13384-1: 2003 - Chimneys - Thermal and fluid dynamic calculation methods - Part 1:
En 2006 - Chimneys serving one appliance
EN1857: 2003 - Chimneys - Components - Flue liners
EN1457: 1999 and Clay/ceramic flue liners - Requirements and test methods
En 2002
EN 1806: 2006- Chimneys - Clay/ceramic flue blocks for single wall chimneys - Requirements and test methods
EN13069: 2005 - Chimneys - Clay/ceramic outer walls for system chimneys - Requirements and test methods
EN 13063: 2006 - System chimneys with clay/ceramic flue liners - Part 1: Requirements and test methods for soot
resistance
The liner must be safely and securely connected to the outlet pipe of the stove. And your chimney or liner must be swept
at least once each heating season and in accordance with local regulations.
Your fireplace
If cement mortar has been used on the inside or outside of the fireplace during construction or installation then a period of
at least 7 days should be allowed before operation to prevent the cement cracking when drying out. The stove will smoke
slightly when first lit. These are fumes from the high temperature paint curing and baking hard. The house should be well
ventilated during the curing period, which will last approximately twenty minutes. During this period the paintwork of the
stove should not be touched. Only an appliance fitted by an accredited installer guarantees compliance with architectural
and fire prevention regulations. These rules must be followed to ensure the correct and safe operation of the stove. The
flue is extremely important when fitting the stove. Be sure to consult authorised specialists about the connection to ensure
compliance with local building regulations. Bear in mind the following:
� The appliance door must be closed when in use and also when not in use.
� There must be an adequate supply of fresh air when the appliance is in use.
Fire safety measures relating to combustible or temperature sensitive floor surfaces:
� A fire resistant, non combustible covering must be fitted under and around the stove. This must be at least 15cm thick.
� No combustible materials should be stored underneath the appliance (e.g. firewood).
� The safety distances from combustible or temperature sensitive objects, given in the table of technical characteristics,
must be adhered to.
5. COMBUSTION AIR
Contrary to a normal fireplace the stove uses very little combustion air. In most houses entry of fresh air through gaps in
doors and windows is sufficient to provide this air. However, in houses that are well insulated this may not be sufficient. If
so, a ventilation grille should be set into an outside wall near the stove to provide additional combustion air. The combus-
tion air consumption of your particular stove can be found in the technical characteristics. Take account of other heating
appliances or air outlet installations in the same area or on the same combustion air connection. If needs be the total
combustion air consumption for the room(s) should be calculated. If 15 minutes after lighting the fire there is still a
backdraught of flue gases due to weather conditions (e.g. fog, storm) stop lighting the fire until the weather improves. Tip:
be sure to take account of extractors which might be connected in the vicinity of the stove. These create negative pres-
sure, which can lead to disruptions in the supply of combustion air. Any escape of combustion gas is potentially lethal and
can damage the health of the people living in your home.
6. RUNNING IN YOUR STOVE
Run your stove in slowly. Your first fires should be made with a small amount of wood and a gentle flame, allowing the
stresses in the metal to dissipate and the entire installation to dry out. Even after running in your stove, never make
intense, prolonged fires. Little extra heat output is achieved and you risk damaging your stove.

8. OPENING AND CLOSING THE DOOR
Place the handle supplied into the hole provided in the door catch (D). Pull handle towards you to open
the door and push away from you to close the door. The stove surfaces can become very hot. Use
temperature resistant gloves at all times.
9. COMBUSTION PRINCIPLE
The stove is designed so that full of wood, with a slow flame, it will burn at maximum efficiency for several hours.
The stove can be made to burn overnight, very slowly, with little or no flame. This is not advisable because this
incomplete combustion creates extra smoke, which, upon condensation, deposits tar on the stove, chimney and
glass panel. An accumulation of such tar deposits is not only unsightly but also requires regular chimney cleaning
to prevent chimney fires. If you are burning wet or green wood then the Combustion Air Control should be left open
enough to ensure the creation of a slow, gentle flame.
� Radiant heat
This is given from the hot embers and stainless steel and vermiculite back panels. The radiant heat is transmitted
through the glass panel into the room and heats the immediate area in front of the stove.
� Convection heat
Cool air enters via the cold air inlet, (A). It then passes along the base of the stove up the back and over the top
before being expelled from the primary hot air outlet, (B). This convection air reaches the farthest corners of the
room.
10. CONTROLS
Combustion air control (C)
This controls the amount of combustion air entering the stove thereby controlling the heat output. It is situated on
the top right hand side of the door.
� To open - Slide to the right for greater heat output but with greater wood consumption.
� To close - Slide to the left for slightly less heat output but much less wood consumption.
Being situated at the top of the door the incoming pre-heated combustion air creates a high velocity air wash effect
over the entire inner surface of the glass panel. This helps keep the glass cleaner for longer.
11. LIGHTING
The highest output is achieved by means of "top-down" burning. To achieve this, do not fill the stove in the traditional
way.
� Traditional way: what is meant here is laying down paper first, then kindling and finally large logs. With this method
the load is limited when lighting the fire.
� "Top-down" burning: this is done by loading the large logs first, then the smaller pieces, and the paper on top.
In this case combustion takes place from the top down and is known as "Top-down" burning.
From cold
1. Fully open combustion air control.
2. Open door.
3. Place the logs in the “traditional way” or “top down” way.
4. Light the fire and close the door.
5. Leave the combustion air inlet fully open until the wood is burning and the ashes glow.
6. Choose a control setting. The best operation setting is around 60% Open
Reloading
1. Fully open combustion air control.
2. Open door.
3. Using poker provided rake hot embers evenly around the vermiculite base.
4. Place fresh logs on top of embers.
5. Close the door and burn fiercely until flame has caught hold and embers are glowing.
6. Choose a Control Setting. The best operation setting is around 60% Open
Note: Do not load wood higher than the vermiculite walls.

BURNING WOOD IN A SMOKE CONTROL AREA
You must purchase a smoke control version of the Mendip stove Christon D600 which is modified slightly to comply with
regulations. Any change to this modification will invalidate the stoves compliance for smoke control areas.
Order Product M 00643-00-00-00-00 Christon 600 SE with 3 sided frame
M 00644-00-00-00-00 Christon 600 SE with 4 sided frame
Any change to this modification will invalidate the stoves compliance for smoke control areas.
The Clean Air Act 1993 and 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 "unauthorised 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).
The Secretary of State for Environment, Food and Rural Affairs has powers under the Act to authorise smokeless fuels or
exempt appliances for use in smoke control areas in England. In Scotland and Wales this power rests with Ministers in the
devolved administrations for those countries. Separate legislation, the Clean Air (Northern Ireland) Order 1981, applies in
Northern Ireland. Therefore it is a requirement that fuels burnt or obtained for use in smoke control areas have been
"authorised" in Regulations and that appliances used to burn solid fuel in those areas (other than "authorised" fuels) have
been exempted by an Order made and signed by the Secretary of State or Minister in the devolved administrations.
Further information on the requirements of the Clean Air Act can be found here: http://smokecontrol.defra.gov.uk/ 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
Refuelling on to a low fire bed
If there is insufficient burning material in the firebed to light a new fuel charge, excessive smoke emission can occur. Refuelling
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 thereare too few embers in the fire bed, add suitable kindling to prevent excessive smoke
Fuel overloading
The maximum amount of fuel specified in this manual should not be exceeded, overloading can cause excess smoke.
The following text may be required depending on appliance operation and instructions:
Operation with door left open
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.
Dampers left open
Operation with the air controls or appliance dampers open can cause excess smoke. The appliance must not be operated
with air controls, appliance dampers or door left open except as directed in the instructions

13. CLEANING
Cleaning is best performed when the stove is cool.
Glass
The specially designed forced hot air wash system and vermiculite insulation helps keep the glass cleaner for
longer. However, if your glass becomes dirty.
1. Open the door.
2. Apply spray or gel type glass cleaner onto a clean cloth or kitchen paper. Apply to the inside surface of the glass
(Be
careful as most glass cleaners are extremely caustic and can damage the painted surface).
3. Leave to soak.
4. Wipe off tar deposits using a slightly damp cloth. Polish with a dry cloth or paper.
DO NOT USE ABRASIVE CLEANERS
Ash cleaning
The stove has a fixed ashtray. Clean daily with the metal scoop provided. The scoop is hinged. With the handle
in a horizontal position, and locked, the scoop acts as a shovel. With the handle unlocked, and hinged upwards,
the scoop acts as a bucket.
1. Open the door.
2. Rake hot embers to one side of the firebox so that they can be used to re-start
the fire.
3. Rake spent ash to other side of the firebox and to the rear of the stove.
4. With the scoop in the horizontal position, and locked, enter into the stove in a
forwards to backwards direction and shovel up excess ash.
5. Unlock and hinge the handle of the scoop upwards and remove from the stove.
Take to the ash deposit.
6. Re-rake hot embers evenly over the vermiculite base
7. Place fresh wood on embers.
Note: Leave 1-2cms of ash on the vermiculite base. The ash insulates the hot embers and protects the vermiculite.
Place firelighters on top of the ash and not directly on top of the vermiculite.
Paint
Wipe off ash deposits on the paint by using a soft haired brush, cotton cloth, or the suction brush attachment of a
vacuum cleaner. Do not wash the stove.
Cold air inlet
Periodically open the air inlet cover plate and wipe away ash deposits that may have accumulated underneath the
stove with a dry cloth.
14. MAINTENANCE
Paintwork
Repaint the stove using only heat resistant paint. Only repaint the stove when it is completely cold. Before
spraying be sure to cover all parts of the stove that do not need to be sprayed (window and fireplace for
example), and to de-grease any parts to be re-sprayed. Follow carefully the instructions written on the spray can.
Chimney cleaning
It is important to have your chimney cleaned once a year. To do this the smoke damper must be removed from
the appliance. To remove the smoke damper, follow the instructions below with care.
1. Open door and remove the smoke deflector (D). To do this, place your hand on the smoke deflector clamp (C)
and rotate the back of the clamp upwards. The clamp will now come free from the deflector and you can move
it towards you and out from the stove. See photos 1 to 5.
Note: The clamp (C) and deflector (D) both have a front and back, (A) and (B). You will need to bear this in mind when
re- assembling the smoke damper.
2. You can now remove the smoke deflector (D) by raising the left hand side and lowering the right hand side, so that
the right hand side can be turned to the front and the plate removed. See photos 6 to 9.
3. The smoke damper (E) is removed by sliding it backwards and letting it drop down. See photo 10.
4. To replace the assembly work in reverse order. Be sure when reassembling that you first mount the smoke damper
operating shaft (F), photo 12, in the guide hole (G), photo 6, before placing the grooves of the smoke damper (E)
onto the fixing strips. Now move the smoke damper forwards to prevent it from dropping.

15
Broken glass
The glass panel is heat resistant and very tough. However, it can be broken through lack of care. By applying
the following tips you will prevent any damage.
� Never leave wood sticking out in front of the stove. Otherwise, when closing the door the protruding wood could
pierce the glass.
� When filling the stove with wood never do so in a dangerous manner i.e. that the wood can fall forward and break
the glass.
� When cleaning the glass do not apply excessive pressure.
If your window does break, consult your installer.

16
Replacing broken glass
Order a glass replacement kit for your specific stove model and size from your nearest dealer. The model specification
can be found on your guarantee card.
1. Remove broken glass from door.
2. Take the replacement glass and feed the top edge up into the top of the door. The bottom edge of the glass will then
drop into place.
3. Push glass downwards to fit against the fibreglass rope in the bottom of the door.
It may be necessary to replace the fibreglass rope seal that surrounds the glass on the bottom and both sides of the
frame of the door. The rope is available from your dealer. It prevents air leaking into the stove around the glass. It must
therefore be tightly packed.
15. TROUBLESHOOTING
