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, yourESSE 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.
Permanent external air vents are required for stoves with a nominal output of greater than 5kW.
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, of appropriate quality and moisture content.
Approved fuels
Unapproved fuels
✔Wood logs
✘Wet wood
✘Overly dry wood
✘Treated timber
✘Smokeless mineral fuel
✘Petroleum based fuels
✘Bituminous house coal
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.
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.
3. OPERATING INSTRUCTIONS

3. OPERATING INSTRUCTIONS
For best results, we recommend your wood logs are cut to a length of 300mm, and a diameter /
width of 70mm.
COMBUSTION AIR AND AIRWASH
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, and where appropriate, how they are controlled.
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 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.
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
amount of Tertiary Air 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.

3. OPERATING INSTRUCTIONS
LIGHTING YOUR ESSE STOVE
When your ESSE stove is first lit, it may smoke or give off an odour. 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. You
may hear ‘ticking noises’ for a short period each time the stove is lit. This is also quite normal, and
will stop once the sheet steel and cast iron have warmed up to temperature.
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 controller(s) to the
appropriate level.
Before lighting your ESSE stove, ensure that the fire
grate is fully closed, (pushed to the left), and that Air
Control is fully open (Pushed to the right).
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
Controllable 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.

10
3. OPERATING INSTRUCTIONS
We recommend a maximum load of wood logs of 2.1Kg / hour, which when stacked in the firebox,
should not sit above the row of Tertiary Air holes, located at the rear of the firebox.
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 running from left to right, 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
controllable 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 air controls may be required, depending upon the flue draft and
fuel type. 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.

12
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.
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 both the Air Controls 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 the Air Control to a central position –This will allow a 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.

4. INSTALLATION INSTRUCTIONS
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.
Permanent external air vents are required for stoves with a nominal output of greater than 5kW.
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.
UNPACKING THE APPLIANCE
The stove comes bolted and strapped to a pallet, for simple and secure transportation. To unpack,
first remove the strapping and packaging. Then remove the two bolts holding the stove to the pallet,
using a 10mm spanner. Locate the four Height Adjusting Bolts supplied with the appliance, and
insert them from below into the same four holes in the feet of the stove, using a 13mm spanner.
These can then be individually tightened / loosened as required, to level the stove on an uneven /
sloping hearth. Whilst heat-treated, the pallet has been produced from timber that is appropriate
for use as kindling, so can be broken up and chopped, for this purpose. Finally, dispose of the
remaining packaging responsibly.

4. INSTALLATION INSTRUCTIONS
TOP OR REAR FLUE CONNECTION
The appliance can be installed with either a top or rear connected 6” flue. The stove comes supplied
with a top connection, so if a rear connected flue is desired, it must be converted before fitting in
place.
Before converting the stove to rear flue connection, the rear heatshield must be removed from the
stove, (by releasing the two rear fixings), and the knock out section removed. After converting the
stove to rear flue connection, the heat shield must then be reinstalled onto the stove.

11. If the flue blanking disk doesn’t fit flush with the stove top, remove it and adjust the three
inner screws heads on the flue plate, so as to make the blanking disk sit flush.
CHIMNEY & FLUE
The stove must be installed and connected to the chimney and flue pipe in line with the current
requirements of Building Regulations. As a basic guideline, the chimney and flue installation should…
✔
Have an internal cross section area of approximately 320cm², with a minimum diameter
or square side length of 125mm².
✔
Have a minimum height of 4.5m.
✔
Be free from cracks, severe bends, voids and obstructions.
✔
Ensure where a flue pipe connects to a chimney, the flue passes past the point where
the chimney narrows.
✔
Ensure an appropriate flue draft, as detailed within the Flue Draft section of this
manual.
✔
Take into consideration future access for maintenance and sweeping.
Please consult Document J of the Building Regulations for detailed guidance.
HEARTH
The hearth must be at least 12mm thick and of non-combustible material(s). When in use, the
temperature on the horizontal surface below the stove has been measured at <100°C. There must
be a minimum distance of 225mm from the front of the stove, to the front of the hearth. The hearth
must be of robust construction, capable of taking the weight of the stove. Please consult Document
J of the Building Regulations for detailed guidance.

4. INSTALLATION INSTRUCTIONS
CLEARANCE DISTANCES (COMBUSTIBLES & NON-COMBUSTIBLES)
The appliance comes with a rear heatshield, which must be installed, irrespective whether the
surrounding materials are combustible or non-combustible. Required distances to combustibles,
(with the supplied heatshield), can be found in the Product Specification section of this manual. If a
double wall flue pipe is used for the installation, the permitted distance to combustibles is reduced.
Recommended distances to non-combustibles are also indicated, in the same section.
FLUE DRAFT
An appropriate flue draft is essential, for the stove to work safely and efficiently. When installed,
and prior to commissioning, a flue draft reading should be taken, using the flue draft reading point
located in the top of the right hand side of the stove. When both the stove and chimney are warm,
a reading in a range between 1.25mm wg (12 Pa) and 2.5mm wg (25 Pa) should be expected. Any
readings significantly outside this range are likely to cause problems, so further investigation should
be undertaken so as to either reduce or increase the flue draft reading, as appropriate.
COMMISSIONING
Once the installation has been completed, check the flue and chimney connection is fully sealed, and
complete a test lighting of the stove. Instruct the owner on how to use the appliance, and complete
the Commissioning Checklist section of this manual. Finally, ensure that you leave this manual with
the owner, for their reference.
