INTRODUCTION
SAFETY
Safety is the most important consideration when using and installing your stove. If not installed and used correctly, a
house fire could result. Installation must comply with relevant national and local Building Regulations and fire safety
standards.
IN THE EVENT OF CHIMNEY FIRE, EVACUATE THE PROPERTY AND CALL THE EMERGENCY SERVICES.
Your stove will be heavy, and care needs to be taken when lifting - 2 people will normally be required to lift.
UNPACKING
Your stove will have several of its components stored inside the stove itself for transportation.
The flue spigot can also be bolted to the flue outlet – the stove has two options for flue outlet – one on the top and one
at the rear. -Most people use the top outlet but depending on where you intend to position the stove in relation to
your chimney, you may wish to use the rear outlet – in this case, remove the blanking plate at the rear and secure into
the top outlet instead. The collar and blanking plate can be secured with the included bolts and allen key.
Inside the stove you will find a glove which must be used when opening the door or when adjusting air vents when the
fire is hot.
INSTALLATION
Installation of your stove must comply with relevant local and national Building Regulations and fire safety standards.

The stove must not be installed within the specified minimum distances to combustible materials as shown in
the table above. Adjacent walls should be of non-combustible materials and construction, preferably masonry
or brickwork.
When installed inside a fireplace recess (with solid non-combustibles walls) we recommend a minimum 50mm
clearance at the sides and rear of the stove to allow good air circulation and achieve best performance.
Note: The Clarity 5 model has been designed to fit safely inside a 16” (406mm) wide fireplace opening. In this
case the clearance will be less than the 50mm suggested above, but this is still acceptable on this model.
Approved for burning wood logs in Smoke Control areas (DEFRA).
CE tested to EN 13240:2001 by KIWA Gastec (Cheltenham, UK).
EcoDesign 2022 for burning wood.
Your stove will require a constant air supply and should not be used at the same time and in the same
room/space as extractor fans or any device which may draw air supply away from the stove.
The stove should be installed on a level floor with adequate load bearing capacity.
The stove needs to stand on a hearth of non-combustible materials not less than 12mm thick conforming to
Building Regulations.
A Carbon Monoxide detector must be fitted in the same room as the appliance.
NOT suitable for installation in a shared flue system.
If installed in a standard type chimney, a register plate needs to be fitted inside the chimney.
When purchasing flue pipe, 5”/125mm diameter is required for the Clarity 5, Clarity 8, Clarity Vision and
Clarity Double Sided (with 6”/150mm required for the Clarity 12 & Double Sided). The flue pipe must be fitted
INSIDE the flue spigot and sealed with a generous amount of Fire Cement.

OPERATING INSTRUCTIONS
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.
The “Ekol Clarity 5, 8, 12 Vision and Double Sided” has been recommended as suitable for use in smoke
control areas when burning seasoned wood.
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.
FUEL
Wood- All types of wood are suitable provided they are wells seasoned, UNTREATED, and have a moisture
level between 12% and 20%. For soft woods, typically they will need to have been left in suitable storage for
9+ months in order for the moisture to evaporate. For hardwoods, this will usually be 18 months+. It is
recommended that logs should be no more than 5” or 125mm in diameter. Logs should be no more than
260mm in length. If you are unsure of the moisture content of your fuel, then you can buy a moisture meter
which will indicate the moisture levels in your fuel.
Liquid fuels must NEVER be used.
WARNING: Wet timber should not be used as this will create excess tar deposits in the chimney and stove and
could increase the risk of chimney fire. Timber which is not of a suitable moisture content will also create
more smoke and harmful emissions.
Manufactured smokeless coals and anthracite can be used and will all have different qualities and effects. –
Do NOT use Petro-Coke based fuels or any petroleum-based fuels as this will invalidate the warranty. Any
coal burned should be coal suitable for a multi-fuel stove (some coal is only for use on open fires and burns
too hot for a stove).
Never use your stove as incinerator to burn waste or rubbish.

STOVE CONTROLS
Your stove has three sets of air inlet areas-
The upper vent above the door provides air supply for the air-wash system and allows air into the higher areas
of the fire box – this is called the Secondary Air – when this vent is open, the door glass is kept clean by high
speed air rushing downwards across the inside of the glass. By moving the Secondary vent knob to the right,
airflow into the stove is increased. The secondary air vent is set such that the closure plate does not seal fully,
thus allowing some constant air supply into the stove.
The lower vent knob on the bottom of the door controls the provision of Primary Air – this is the primary
source of air supply for combustion. Sliding the knob to the right increases the amount of Primary airflow into
the stove.
The (third) Tertiary vent control is located underneath the stove and controlled by a lever/ knob tucked under
the bottom shelf. Pulling the lever out increases the airflow into the stove. The air is then channelled through
a chamber on the back of the stove and enters the firebox via a series of small holes. Pushing the lever fully in
closes of this air intake partially. This intake cannot be fully closed. This ensures the stove maintains level of
combustion not likely to create excessive smoke.

7
TOOLS
The glove is provided for adjusting the air inlets and for opening the door when the stove is hot, as these
knobs will heat up when in use. NOTE – all parts of the stove will become hot during use and care needs to
be taken to avoid injury through burning.
LIGHTING THE FIRE
•Prior to lighting the fire for the first time, ensure that-
•Installation and building work are complete.
•The chimney is suitable and sound and has been swept and free from obstruction.
•Adequate ventilation and provision for combustion air has been made.
•That the stove installation has been carried out in accordance with Building Regulations and any
applicable local regulations as well as these installation instructions.
•That chimney draw has been checked and within specification. (The stoves has been tested at nominal
output with a flue draught of 12 Pa) Flue draughts in excess of 18 Pa when warm will have a negative
effect on the efficiency, could cause premature wear and damage to the stove.
ENSURE THAT YOU HAVE READ AND UNDERSTOOD THESE INSTRUCTIONS BEFORE LIGHTING THE FIRE, AND
THAT YOU ARE CONFIDENT THE STOVE HAS BEEN INSTALLED CORRECTLY.
The Entire Stove Will Become HOT!
The glove is provided for adjusting the air inlets and for opening the door when the stove is hot, as these
knobs will heat up when in use.
NOTE – all parts of the stove will become hot during use and care needs to be taken to avoid injury through
burning.
ESSENTIAL INSTRUCTIONS BEFORE USE – It is essential to follow these ‘tempering-in’ instructions in order to
avoid serious damage to your stove. The castings of your stove require very gentle ‘normalising’ to release
stresses in the metal formed during the casting process. The high temperature paint finish also requires
curing: -
Initial paint curing:
Note: NEVER wipe the stove in the early stages (prior to paint fully curing), as the paint will be very
soft and will damage easily. NEVER attempt to clean or wipe the paint surface when warm or hot. Please read
the following and follow thoroughly.
The stove is finished in specialist high temperature coating which is air-dry but not yet cured. The stove should
be brought up to temperature gradually over the course several fires to complete this process. If the stove
gets too hot or not hot enough during this process, then the curing process can fail causing issues with the
paint surface.
1) For the first three fires (all on the same night), use KINDLING ONLY, with each burning for 15-20 minutes
and each fire using approx 500 grams of kindling. Start the second and third kindling fires whilst the fire is still
warm from previous fires, but with around 30 minutes cooling time in between. Once the three kindling fires
have burnt through, and whilst the stove is still warm, but slightly cooled, light a normal fire with three dry
logs weighing around 1.2 kgs in total. This fire should burn for between 45 and 60 minutes. Now allow to
FULLY COOL naturally. The paint should now be cured.

8
2) Once the curing process has been completed satisfactorily, normal fires can be lit –
Next Stage - stove tempering:
For the first 3 hours burning use just small wood fires, then for the next 15-20 hours, total burn time, fires
must be very gently increased in temperature and log size and load and NO SOLID FUELS (products other than
wood) must be used during this period. A stove thermometer will be a valuable tool in helping you to achieve
this and to ensure an efficient burn rate in future. After these small fires, gently increase fires over the course
of a week or so. Starting a large fire too soon is likely to damage the stove in which case will not be covered by
the warranty.
Ignition (On-going, once above procedure has been followed)
•Ensure all air inlets are fully open.
•Construct a pile of kindling in the middle of the grate using approximately 500g of kindling wood.
•Light with a single chemical firelighter.
•Partially shut the door but leaving it cracked open slightly.
•After about 5 minutes or when the fire is well established, shut the door.
•After a further 3-5 minutes as the fire starts to die, add a further three small logs weighing approx 0.75
kg (Clarity 5) or 1kg (Clarity 8) 2kg (Clarity 12) 0.75kg (Clarity Vision) or 1.5kg (Double Sided) total.
•Once theses logs are alight, and after about 7 minutes or so, a normal load of 3-4 logs weighing
approximately 1.4kgs (Clarity 5) or 2.5kg (Clarity 8) 3.8kg (Clarity 12) 1.45kg (Clarity Vision) or 3kg
(Double Sided) in total can be added.
•Once this load is burning well, the Primary air vents can be closed, with the Secondary and Tertiary
vents left open.
Refuelling
•Open the Primary air vents.
•Add up to 1.4kg (Clarity 5) or 2.5kg (Clarity 8) or 3.8kg (Clarity 12) 1.4kg (Clarity Vision) or 3kg (Double
Sided) of wood.
•After about 2-3 minutes or when flames from the fresh fuel fully established, close the Primary vents.
•At high power output, your stove will require refuelling approximately every 60 minutes.
•It is important to follow these instructions in order to achieve clean burning and to maximise the
efficiency of the stove.
•Do not leave the fire unattended until flames are well established on the newly charged logs.
•Always refuel onto hot embers.
•Reduced burn rates can be achieved by reducing the openings of the Secondary and Tertiary air vents.
Refuelling on to a low fire bed
•If there is insufficient burning material in the fire-bed 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 there are 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.

9
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 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.
UK Clean Air Act 1993 - Smoke Control Areas
The Ekol Clarity 5, 8, 12, Vision and Double Sided wood-burning stoves are suitable for use in smoke control
areas when used in accordance with these instructions.
WARNING- The high temperature paint covering the stove will give off some fumes during the initial few uses
of the stove. The fumes are non-toxic, but some people may find them unpleasant – Ensure the area is well
ventilated during this period.
The output ratings of this stove are based on around 1.4kg (Clarity 5) / 2.5kg (Clarity 8) / 3.8kg (Clarity 12)
/ 1.45kg (Clarity Vision) / 3kg (Double Sided) of seasoned logs which would require refuelling every hour.
This stove is suitable for intermittent burning and should not be used constantly for extended periods. Not
suitable for overnight burning.
Under certain abnormal weather conditions, e.g. down draughts, it may be difficult to get sufficient draw
through the appliance to achieve good combustion. When this happens, the stove should not be used.
CLEANING/MAINTENANCE
Regular cleaning of the stove is essential for safety and efficiency. The ash-pan should be checked/ emptied at
least after every use, and during use if burning for longer periods. Extra care must be taken when removing
warm or hot ashes.
Step by step maintenance instructions:
1) A minimum of once per year the flue system should be cleaned/swept by a qualified chimney sweep or suitably
qualified stove installer. The servicing of the appliance can usually be carried out at the same time. Whether the system
needs sweeping more frequently than this will depend on use.
2) Baffle plate should be removed and checked for debris twice a year as a minimum depending on use.
Warped/misshapen baffle plates can be a warning sign that the stove has been over-fired (allowed to excessively heat
on one or more occasions).
3) Once removed, brush the baffle using a stiff brush or wire brush to remove any deposits. Clear any debris from the
upper parts of the stove above where the baffles normally sit.
4) Inspect firebricks on both the sides, rear and base for cracks - (some are normal and not a fault. Nor are they
detrimental to the workings of the stove, however it is good practice to be aware as any develop and over time if they
worsen, they may need replacing). If you feel a crack in the firebrick is just cosmetically unsightly it can be filled with a
small amount of fire cement.

10
5) Vacuum or brush out the inner stove box thoroughly.
6) Visually check that the glass is still making a good seal against its rope on the inside of the door frame and that it’s
retaining clips remain firmly in place to the touch.
7) Check that the door is making a good seal with the body of the stove all around (over time the rope will flatten out
and loose some flexibility - when this happens and when it is no longer sealing fully all the way round, it needs to be
replaced). The rope size used here is a 10mm-Soft type.
8) Blemishes or scratches to the paintwork can be touched up using a suitable high temperature stove paint in
a spray can. Ensure the stove is cool and clean before applying and follow the paint manufacturer’s instructions. Contact
Saltfire Stoves directly if you are unsure which paint to use.
Throughout the season, it is good practice to keep the stove in generally good clean order which will prolong the life of
serviceable components and enhance the experience you have with your fire.
9) NEVER wipe the stove in the early stages (prior to paint fully curing), as the paint will be very soft and will damage
easily.
10) To keep the outer body clean, simply dust over with a clean soft duster when cold.
11) If there are marks which cannot be removed with a duster, use a slightly moistened cloth very gently, but only when
the stove is cool and has not been in use. Then pat dry with absorbent paper towel.
12) Regularly vacuum soot and dust from around the inside of the door and around the glass and rope seals.
13) If glass gets dirty on the inside from soot, clean with liquid ‘stove glass cleaner’ and a soft cloth OR with
an “Atmosfire Dry Wiper”, produced by Schott, (manufacturers of stove glass), and available online. Do this as
soon as possible once the soot appears, but only when the fire is completely cool. Never use newspaper or soot or any
other abrasive or cleaning method on the glass.
If the glass becomes stained from the inside, the air-wash vent may need opening more during use. (See
‘troubleshooting guide’ for other possible causes).
The high temperature paint which your stove is finished in should last several years with normal use, but
when it does eventually require re-finishing, black heat resistant paint in spray cans can be purchased from
most hardware stores. – Do not use regular paint which is not high temperature resistant.
After prolonged periods of not using the fire, the stove and flue system should be checked for blockages prior
to re-lighting.
We recommend regular servicing and safety checks are carried out by a qualified engineer.
There must be no unauthorised modification of the appliance. Use only replacement parts recommended by
the manufacturer.

Troubleshooting Solutions for Stove Problems
Installed and used correctly your stove will provide years of warmth with little effort but used incorrectly will be difficult
to achieve the results you expect and can be damaged.
Combustion is a complex chemical process with many variables, all of which need to be correct for your stove to burn
correctly. Taking the time to understand these variables and the combustion process will make your life with your new
stove a happy one.
1. Stove is difficult to light / keep lit
Common causes:
a. Damp fuel – Wood should be maximum 20% moisture and ideally 12-15%. We strongly advise purchasing a digital
moisture meter to test your logs. Always split logs in half and test the centre of the log.
b. Poor draught and chimney strength – Your chimney needs to pull through adequate air for combustion. Flue draught
should be between 12Pa and 18Pa – if in doubt consult a local expert.
c. Logs too big – Always start fires small and gradually build them up. Begin with paper or solid firelighters, building a
small fire with kindling (small sticks of wood) until the kindling is well alight and hot. Then gradually build the fire with
your wood logs (not too thick). (Splitting the logs will increase the surface area allowing more thorough burning). Once
the firebox is up to temperature, slightly larger logs can be added.
d. Chimney/flue blocked – Excessive soot should not be allowed to build up in the flue – flues should be professionally
cleaned when required and, in any case, at least once per year, or more if your chimney / fuel type is causing excessive
soot to build up.

13
2. Fuel burns too quickly
The rated output on your stove is based on burning dry seasoned hardwood and re-fuelling every hour. By turning down
the vent controls the fuel will burn slower and last longer.
Common causes:
a. Excessively strong chimney draught – If by turning down the vents the fire still burns too quickly, this is normally due
to excessively strong draught on the chimney. This will lead to over-firing of the stove, which is inefficient, losing
excessive heat into the chimney and pulling too much cold air through the house. A flue damper fitted into the first
section of flue pipe can help to calm a chimney draught.
b. Fuel type/size – try experimenting with different types of wood/fuel and different sized logs. Coal and slightly larger
logs will burn slower. Softwood such as pine will burn particularly fast. Kiln dried wood is NOT recommended – It is likely
to burn too fast – always use seasoned, naturally dried logs (hardwood) where possible.
3. Smoke comes back into room
A small amount of smoke entering the room when you open the stove door is normal but should stop after a few
seconds….
If smoke ever leaks constantly into the room stop using the fire immediately, shut down all vents on the stove, open
windows and exit the room. Do not use the stove until a local expert has established the problem.
Common causes:
a. Insufficient air supply into the room – do you have an air brick of sufficient size to feed the stove with air?
b. Blocked chimney – have the chimney swept and checked by a registered chimney sweep.
c. Insufficient chimney draught – can be due to a variety of reasons – please refer to previous text under “Poor draught
and chimney strength”
d. Rapid condensation of the gases - causing them to slow down and back up in the chimney – this can be due to too
broad a chimney/flue, relative to the size of the appliance or the flue not being adequately insulated. You may need a
flue liner and/or insulation in the chimney.

14
4. Glass gets dirty quickly
Common causes:
a. Top vents not open – Your stove has a top vent this controls the Airwash system – the top vent needs to be
constantly open adequately to ensure enough air is coming into the stove. No Airwash will work fully when the stove is
burning very slowly (slumbering).
b. Primary Vent left open – Primary vent when left open will interfere with the operation of the Secondary (Airwash),
causing blackening of the window. Always shut Primary once fire is established, and only ever open as much as
necessary to get the fire going or to give a short ‘boost’ to new wood when refuelling.
c. Poor fuel – wet wood or softwood (e.g. pine) will produce a lot of tar, creosote and soot, dirtying the glass and
eventually blocking the flue.
d. Insufficient chimney draught – see previous note under “Poor draught and chimney strength”.
e. Baffle plates incorrectly fitted – see previous diagram for correct positioning of baffles.
f. Fuel loaded to close to window – The wood needs a good clear distance away from the glass – otherwise it will
produce thick black marks on the glass and interfere with the Airwash airflow.
5. Not enough heat being produced
Common causes:
a. Poor quality fuel – logs should be dry well seasoned hardwood.
b. Poor draught and chimney strength – see previous notes.
c. Excessive draught – too much heat being lost up the chimney – try a damper in the flue.
d. Insufficient air supply - Check air supply is sufficient / vents on stove are clear. Does the room have a vent?
e. Not enough fuel being burned – the rated output of your stove is based on burning beech wood (typical of most
hardwoods), refuelling once per hour. 1kg of this wood has approximately 4-5 kw hours of energy.
f. Larger stove / stove with higher output required for room size.
6. Too much heat in room
Common causes:
a. Excessive chimney draw – try fitting a damper unit in flue
b. Too much air supply – close down primary vent, then if still too hot reduce tertiary and secondary vents.
c. Stove may be too large for room size.

15
7. Grate deformed / Baffle plate deformed
Your stove will have been designed to operate correctly for many years with a relevant quantity of fuel and re-loading
times. The grate and baffle plate can over time start to bow/deform – this can only be caused by very high
temperatures. Using Solid Fuel products can accelerate this process but burning wood at too high a temperature can
also cause damage to internal parts.
Common causes:
a. Excessive chimney draw– try a damper in the flue.
b. Excessive primary air supply – close down primary vents.
c. Incorrect fuel – NEVER use Petroleum Coke, Bituminous fuel, Housecoal or any unauthorised fuel.
d. Stove overloaded – excessive burning of too much fuel.
The baffle plate and the inner linings of the stove, and the grate all designed to be replaceable parts – call us if you need
to order new ones.
If you are experiencing problems including insufficient heat being provided – to help establish the cause and
solution we will need to know specifically what fuel you are burning and the rate (kg per hour) at which you
are burning the fuel, and in the case of wood, the average moisture content of the centre of the logs (we
suggest using a moisture meter to check moisture levels in logs).
Only by monitoring this burning rate over the course of several burn cycles can we quantify the outputs being
produced and begin to establish a cause of the problem.
If you are experiencing these problems please email us at [e-mail] with your invoice
number, name and purchase date, detailing as much information as possible considering all of the above
information (and the general troubleshooting advice we give for all stoves). The more accurate and detailed
the information the quicker we will be able to help you to establish improvements you can make to your
system.
