Welcome to the ESSE family. We’ve poured all of our knowledge, expertise and passion for designing
and manufacturing market leading stoves, dating back to 1854, into producing your ESSE stove. All
ESSE stoves are manufactured at our factory in Barnoldswick, Lancashire, and we’re confident that
if appropriately installed, maintained and cared for, your ESSE stove will provide you with many years
of room heating, comfort and joy.
Before you fire up your ESSE stove for the first time, ensure that your installer has installed the stove
in line with the ‘Installation’ section of this manual, and that the flue and chimney has been swept.
The stove is not suitable for use in a shared flue.
As you would expect, when in use, all parts of the stove become hot, so always use the supplied
operating tool or glove when interacting with your ESSE stove. A fireguard manufactured in
accordance with BS 8423:2002 should be used, if it is likely that children or pets may come into
contact with the appliance. The stove is suitable for intermittent operation. Do not use an aerosol
spray close to the stove when alight.
These instructions provide all the necessary information to both install, then operate your ESSE
stove. The key information relating to your stove, including the serial number, can be found on the
data plate, located at the rear of the stove. Simply swing the data plate up to access the information.
Please quote the model and serial number, in any future communication with your retailer or the
manufacturer.

3. OPERATING INSTRUCTIONS
CO ALARM
Your installer should have ensured that you have a Carbon Monoxide (CO) alarm fitted, in the same
room as your ESSE stove. This is a requirement of the BS EN 50292:2013 standard, and you should
make sure that you are familiar with the operation of this essential piece of equipment.
VENTILATION
All stoves require a consistent supply of ‘combustion air’, to allow for the combustion of the fire. As
a general rule, permanent external air vents are not required for stoves with a nominal output of
5kW or less. However, some newer houses with a low air permeability may need a permanent
external air vent, irrespective of the nominal output of the stove. Your installer will have advised
you on the requirements, within your situation. For more information, see the ‘Ventilation’ section
of the ‘Installation Instructions’ part of this document.
FUEL
Your ESSE stove has been designed to burn wood logs, incorporating our unique ‘Particulate
Reburn™ Technology’, which contributes to making it the cleanest wood-burning stove we’ve ever
built.
Approved fuels
Unapproved fuels
✔Wood logs
✘Wet wood
✘Overly dry wood
✘Treated timber
✘Smokeless mineral fuel
✘Petroleum based fuels
✘Bituminous house coal
✘Printed glossy materials, (eg magazines)
This appliance is not appropriate for use as an incinerator, and unsuitable fuels should
not be used. Failure to follow this requirement will invalidate your warranty.
WOOD LOGS
Burning wood logs within your ESSE stove provides sustainable, efficient and ‘clean’ heating to your
room. The moisture content of your wood is very important, as this affects both how ‘cleanly’ your
stove will burn, and also how long the fuel will burn for. Referred to as ‘green wood’, recently felled
wood will almost certainly have a moisture content that is too high to burn efficiently and cleanly.
Similarly, overly dry wood will burn quickly, with higher emissions, making your stove less
economical to run.
3. OPERATING INSTRUCTIONS

7
3. OPERATING INSTRUCTIONS
We recommend using wood logs with a moisture content of 15 –20%. This is best achieved by either
storing green wood yourself for a period of 12 –18 months, and checking regularly with a moisture
detector, or purchasing it from a reputable fire wood specialist, who is able to control the moisture
content of their wood logs.
For best results, we recommend your wood logs are cut to a length of 200mm, and a diameter /
width of 120mm.
COMBUSTION AIR, AIRWASH & CONVECTION AIR
ESSE stoves are designed to achieve the most efficient heat outputs, with the ‘cleanest burn’. To
achieve this, significant research and development investment has been given to how to provide
appropriate levels of ‘combustion air’ to the correct parts of the fire, at the correct time of the burn
cycle.
Combustion air is drawn into your ESSE stove from two locations, one of which is controllable. It is
important to understand the function of each of the two, and where appropriate, how they are
controlled. Your ESSE stove also incorporates two further air management technologies, which
provide additional benefits.
Controllable
Combustion Air
Controllable Combustion Air enters your ESSE stove from the top of the
appliance, dropping down into the firebox, via the ‘Airwash’ (see below).
The Controllable Combustion Air control incorporates Precision Burn™
technology, to provide a more precise adjustment, to better control the
air supply and burn rate. When moved to the right, there is more air and
a fiercer burn rate, whilst moved to the left, there is less air, and softer
burn rate.

3. OPERATING INSTRUCTIONS
Tertiary Air
Tertiary Air enters your ESSE stove from the rear, through the rear fire
bricks, to provide additional combustion air directly into the flames. The
Tertiary Air volume is not adjustable, but carefully positioned to help
achieve improved efficiency and a clean burn.
Airwash
The Airwash is created by Controllable Combustion Air being pushed
down the inside face of the glass window, creating an air curtain that
helps reduce build-up of soot, keeping the glass clean.
Convection Air
Your ESSE stove has an inbuilt Convection Air system, to help push hot
air forward out of the stove, to better heat up the room. Natural
convection draws cold air into the top of the stove through rear slots,
which is heated up as it passes through the stove, before being pushed
out into the room.

3. OPERATING INSTRUCTIONS
PARTICULATE REBURN™ TECHNOLOGY
Your ESSE stove incorporates Particulate Reburn™ Technology, which dramatically reduces the
emissions when burning wood logs, far above and beyond the demands of the Ecodesign
requirements, (which comes into force in 2022). As such, your ESSE stove is one of the cleanest
burning stoves available.
Particulate Reburn™ Technology creates three distinct areas of combustion within the stove, which
both increases the heat generated from the wood log fuel, and dramatically reduces emissions, by
burning more hydrocarbon particles than conventional stoves.

A second area of combustion, where
additional tertiary air is directed at
unburnt hydrocarbon particles,
contained within smoke rising up from
the wood logs.
A third area of combustion, where
remaining hydrocarbon particles pass
through the catalytic combustor, which
reduces the temperature required for
the particles to combust, reigniting
them.
The three areas of combustion from
Particulate Reburn™ Technology
At the heart of the third area of combustion is the Catalytic Combustor, which uses a coating of noble
metals to reduce the temperature required to achieve combustion, reigniting any unburnt
hydrocarbon particles, as they pass through the chamber.

10
3. OPERATING INSTRUCTIONS
The catalytic combustor is positioned above a
particle filter, and both are held together on a
sliding cartridge. As a result, both parts can be
simply moved to one side, allowing smoke to
‘bypass’ them, and pass directly up the flue.
The cartridge containing both parts can be
removed for cleaning and inspection.

sliding cartridge.
Do not burn wet wood logs, chemically treated timber or heavily printed glossy
materials, (eg magazines), as this can damage the catalytic combustor.
Bypassing the
Catalytic Combustor
The Catalytic Combustor is most efficient when your ESSE stove has
reached a steady operating temperature. With this in mind, and so as to
prologue its life, the Catalytic Combustor should be bypassed when
lighting your ESSE stove, by simply pulling the ‘Bypass Boss’ out from the
top right hand side of the stove. Once the fire has taken hold, the
catalytic combustor can be positioned back into place. Similarly, it is
advisable to bypass the catalytic combustor when refuelling your ESSE
stove.
When fully opened, the bypass boss extends 150mm to the right of the
stove. However, to successfully bypass the catalytic combustor, it must
be opened to extend to a minimum of 75mm to the right of the stove.

3. OPERATING INSTRUCTIONS
Anticipated Life
Well maintained and cared for, the Catalytic Combustor can remain
effective for up to ten years. However, to ensure the continued cleanest
burn, and maximum efficiency, we recommend replacing the Catalytic
Combustor every five to six years.
It is important to regularly inspect the Catalytic Combustor for signs of
physical damage and build-up of creosote, which can lead to the airflow
being blocked. In either of these scenarios, the Catalytic Combustor
should be replaced. We recommend having the Catalytic Combustor
inspected annually by your service professional, at the same time as the
stove is inspected and the flue / chimney swept. Should your stove’s
efficiency and / or heat output drop, or if there is a noticeable increase
in visible smoke emitting from your chimney, this may also suggest the
need to replace the Catalytic Combustor.
Maintenance
To prolong the life of the Catalytic Combustor, and keep the efficiency
and heat output of your ESSE stove high, both the Catalytic Combustor
and Particle Filter should be cleaned regularly. We recommend having
both parts cleaned annually by your service professional, at the same
time as the stove is inspected and the flue / chimney swept. To do so,
when the stove is cold, remove the both Catalytic Combustor and Particle
Filter from the stove, and wrap them in a plastic bag. Gently tap both
parts, one at a time, allowing any build-up of dust to fall into the bag,
before removing the parts, sealing the bag, and disposing of it into a
waste bin. Then either use a domestic vacuum cleaner or a soft bristle
brush, to remove any remaining dirt within the two parts. Once cleaned,
both parts should be repositioned within your ESSE stove.

3. OPERATING INSTRUCTIONS
Removal and replacement of the Catalytic Combustor and Particle Filter
1. Remove the Bypass Boss from the shaft by
unscrewing it anticlockwise.
2. Remove the top, side then rear fire bricks.
3. Slide the chamber containing the Catalytic
Combustor and Particle Filter fully to the left, before
carefully allowing it to swing down free.
4. Remove the Catalytic Combustor and then the
Particle Filter from the cartridge, for cleaning or
replacement, retaining the sealing rope.
5. Once the two parts have been cleaned or
replaced, reassemble the cartridge, reinstalling it
along with the chamber into the stove, and slide
into position.
6. Reinstall the bypass boss, tightening up clockwise.
Finally, replace the firebricks.

3. OPERATING INSTRUCTIONS
LIGHTING YOUR ESSE STOVE
When your ESSE stove is first lit, it may smoke, give off an odour, or make ‘ticking noises’. This is
quite normal, as the materials used within its manufacture are heated up for the first time. These
symptoms will stop within a short period, but ensure that the room is well ventilated during this
‘settling in’ process.
The pallet that your ESSE stove was supplied on has been produced from timer that is appropriate
for use as kindling, so can be broken up and chopped, for this purpose.
Initially only light a small fire, for a period of 1 –2 hours, to dry out any moisture found within the
flue and chimney.
Whilst lighting the fire, do not leave your ESSE stove unattended, until the fire is
established, the door is fully closed, and you have adjusted the air controller to the
appropriate level.
Before lighting your ESSE stove, ensure that the fire
grate is fully closed, (pushed to the left), and that the Air
Control is fully open (Pushed to the right). Pull out the
Bypass Boss to the maximum distance.
Lay three small pieces of kindling wood next to each
other in the centre of the grate, and place a few
firelighters / tightly rolled up newspaper on top of them.
On top, place two pieces of kindling wood at ninety
degrees to the first three, either side of the firelighters /
newspaper. Add three more pieces of kindling wood on
top, in line with the bottom row, to create a small lattice
structure. Safely light the firelighters / newspaper, and
allow the flames to take hold.
Once the fire has taken hold, place two small wood logs
onto the growing flames, and close the door, but leaving
it slightly ajar. Once the flames have established on the
small wood logs, (typically within 3 –5 minutes), add the
desired load of larger wood logs, and fully close the door.
When the fire has fully established, slowly reduce the
combustion air volume, by moving the Air Control to the
left. Continue to use the Air Control to control the fire,
until the flames are slowly ‘dancing’ on top of the wood
logs.
We recommend a maximum load of wood logs of 1.75Kg / hour, which when stacked in the
firebox, should not sit above the six Tertiary Air holes, located within the rear fire bricks.

14
3. OPERATING INSTRUCTIONS
The door should only be opened during the initial lighting and refuelling of your ESSE
stove. If left open during normal operation, you may experience excessive smoke
emitting into your room.
REFUELLING
Refuelling should be undertaken whilst the flames on the current fuel are still established, or you
may experience excessive smoking. If the current fire has died out, reignite the fire with additional
kindling, before adding additional fuel. When positioning fuel into the firebed, ensure that the fuel
is not touching the back or side walls, or the glass window, as this will result in a less clean burn.
To enjoy optimum wood burning, leave an ashbed of 1 –2cm of ash within the fire grate. First rake
the current fuel, to create a bed of hot embers, on which to place the new fuel. Then place the new
wood logs onto the hot embers. For the most efficient and cleanest burn, two wood logs should be
placed in a ‘V shape’, as shown below. Close the door, and open the Air Control, to allow flames to
take hold on the new wood logs. Once the fire is once again established, slowly reduce the secondary
air volume, by moving the control to the left. Continue to use the Air Control to control the fire, until
the flames are slowly ‘dancing’ on top of the wood logs.
Do not ‘overload’ the fire with excessive amounts of fuel, as this will result in over-firing,
and may cause permanent damage to your ESSE stove.
Optimum positioning of wood logs, when refuelling –Top View
REDUCED BURNING
Once a fire has established, close down the Air Control, and ensure that the door is firmly closed.
Experimentation with the setting of the Air Control may be required, depending upon the flue draft
and fuel load. A build-up of soot on the inside face of the glass window is likely.

3. OPERATING INSTRUCTIONS
THE FIRE GRATE AND RIDDLING
Your ESSE stove will be hot during and after use. Always use the supplied Operating
Tool and / or Stove Glove to riddle the appliance.
The Fire Grate in your ESSE stove is made of two parts –The Grate and the Riddle Plate. The Fire
Grate can be ‘riddled’ by sliding the Riddle Plate quickly between the left and right position, forcing
excess ash to fall through the slots in both parts, into the Ashpan below.
To ‘riddle’ the Fire Grate, position the straight end of the Operating Tool on the rear Riddling Boss,
so it rests on the top of the front Riddling Boss. Alternate the Operating Tool position quickly
between the left and right side position, which will force ash to drop into the Ashpan.
Positioning the Fire
Grate
The Fire Grate should be ‘closed’, with the Riddle Plate positioned to
block the slots in the below Grate. The Fire Grate should only be ‘riddled’
when the ashbed grows above 20mm deep, so as to remove some of the
excess ash.
.
ASHPAN
Your ESSE stove will be hot during and after use. Always use the supplied Operating
Tool and / or Stove Glove to remove and replace the Ashpan. Only remove the Ashpan
when the appliance and ash it contains are cool.
When the Fire Grate is ‘riddled’, ash will fall into the Ashpan below. When the Ashpan is approaching
being full, it should be emptied, and the ash disposed of. To remove the Ashpan, insert the folded
end of the Operating Tool into the slot at the front of the Ashpan, and carefully pull it forward, sliding
it clear of your ESSE stove.
Never allow the level of ash to build up so it touches the underside of the Fire Grate, as this can
cause permanent damage to your ESSE stove. Never pour hot ash into plastic waste bags or bins.

16
3. OPERATING INSTRUCTIONS
CLEANING & MAINTENANCE
Your ESSE stove should be inspected frequently, and any required maintenance undertaken. We
recommend that your ESSE stove is serviced once a year by a qualified service professional.
Repairs or modifications should only be undertaken by ESSE authorised professionals.
Only genuine ESSE replacement parts should be used, or your warranty may become
invalid.
General cleaning
The exterior cast iron and sheet steel parts should be cleaned with a
soft brush or lint-free cloth. Should areas of the appliance need re-
painting, high temperature aerosol paints are available from your
retailer.
Catalytic Combustor
Regular inspection of the Catalytic Combustor and Particle Filter is
recommended, as described within the Particulate Reburn™
Technology section of this manual.
Glass Window
If the glass window needs cleaning, use a damp cloth. If stubborn stains
remains, use a dedicated glass cleaning solution. Do not use abrasive
cleaners or pads, as these can scratch the surface, which may cause the
glass to fail prematurely. Before relighting the appliance ensure that
the glass has fully dried.
Rope Seals
Ensuring a firm seal between the body of the appliance and the closed
door is essential for the efficient and clean burning of your ESSE stove.
The rope seals on the inside face of the door should be inspected
regularly, and replaced as necessary.
CHIMNEY SWEEPING
To ensure continued safe and efficient use of your ESSE stove, we recommend that your chimney is
swept by a professional at least once a year, typically before the stove season. Where the appliance
is used throughout the year, we recommend more regular sweeping.
SAFE SHUTDOWN
In the unlikely event of a chimney fire, a fault occurring with the appliance, or extreme weather
affecting the burn of the appliance, move the Air Control to the left, closing down the combustion
air supply to the minimum volume. This will minimise the intensity of the flames in the appliance,
which will then slowly die out. In the case of a fire in the chimney or flue, immediately call the Fire
and Rescue Service for assistance.
SEASONAL USE
If your ESSE stove is to not be used for a period of time, first clean the appliance as described within
the ‘Cleaning & Maintenance’ section of this manual. Empty both the Fire Grate and Ashpan of all
ash, before closing the door. Position both the Air Control to a central position –This will allow a

17
3. OPERATING INSTRUCTIONS
flow of air, preventing a build-up of moisture inside your ESSE stove, which can lead to rusting.
Before re-lighting the appliance, remove the top baffle bricks, to remove any debris, and check for
blockages within the flue.
WARRANTY
Your ESSE stove has been built to the highest standard using premium materials, and comes with a
two year manufacturer’s warranty. Register your ESSE stove, by either completing and returning

PLANNING THE INSTALLATION
It is the installer’s responsibility to ensure that when installing the appliance, the requirements of
the Health and Safety at Work Act 1974 are met.
The installation instructions within this manual provide a guide for safe and appropriate installation,
but it is the responsibility of the installer to ensure that the requirements of applicable British
Standards are met, in particular BS 8303 and BS EN 15287:2007, relating to the installation of solid
fuel appliances.
When considering the installation design, ensure appropriate access is provided for cleaning of the
appliance, flue pipe and chimney flue. This appliance is suitable for intermittent operation, but is not
suitable for use in a shared flue system. The appliance should not be used in the same room as an
extractor fan, as this can cause the stove to emit fumes into the room.
VENTILATION
All stoves require a consistent supply of ‘combustion air’, to allow for combustion of the fire. As a
general rule, permanent external air vents are not required for stoves with a nominal output of 5kW
or less. However, houses with a low air permeability, such as newer builds, may require a permanent
external air vent. Document J of the Building Regulations explains that should a stove be installed in
a room with an air permeability of lower than 5.0m³/(h.m²), a permanent external air vent is
required, irrespective of the nominal output of the stove. External air vents must be positioned so
they are not liable to be blocked. Based upon the requirements within Document J of the Building
Regulations, a 5kW stove has the below air vent area requirements.

CO ALARM
Building regulations require that whenever a new or replacement fixed solid fuel or wood / biomass
appliance is installed in a dwelling, a carbon monoxide (CO) alarm must be fitted in the same room
as the appliance, in accordance with BS EN 50292:2002. Please consult Document J of the Building
Regulations for detailed guidance. The installation 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.
