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 cook stove. All ESSE cook 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 cooking, room heating, comfort and joy.
Before you fire up your ESSE cook 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 cook 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 cook
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 cook stove. The key information relating to your stove,
including the serial number, can be found on the data plate, located behind the
bottom right door. Please quote the model and serial number, in any future
communication with your retailer or the manufacturer.

2. OPERATING INSTRUCTIONS
BEFORE USING YOUR COOK STOVE
Ensure that all protective packaging has been removed. The hotplate has been
oiled at the factory to prevent rusting and therefore will require wiping with a
damp cloth and drying with a paper towel, before use.
This appliance is suitable for burning wood only. An extractor should not be
fitted within the same room as the appliance.
Do not place tea towels or similar items on the handrail.
GETTING TO KNOW YOUR COOK STOVE
Air Controller
This is used to control the fire intensity, by managing the
amount of air supplied to the fire. When moved to the left,
there is more air and a fiercer burn rate, whilst moved to
the right, there is less air, and softer burn rate.
Oven Damper
This is used to help control the temperature of the oven,
by routing the hot gasses from the fire away from the
oven, if desired. To close the damper, (and maximise the

oven temperature), rotate the dial clockwise. To open the
damper, (and reduce the oven temperature), rotate the
dial anticlockwise.
Flue Damper
This is primarily used to help manage an occasional
excessive flue draft, for example, during adverse weather
conditions. However, an appropriate flue draft should be
created during the installation of the appliance (See the
flue draft section of this document for more information).
It can also be used to provide additional air, when first
lighting the fire. The Flue Damper is opened by pushing
the lever backwards towards the rear of the appliance,
and closed by pulling it forward, towards the front.
The firebox is accessed through the large glass fronted fire door, which is opened
by rotating the catch 90° anticlockwise. The oven is behind the top right door,
which is opened by rotating the catch 90° clockwise. Please note, when in use,
both of these catches will become hot, so always use the supplied glove to open
and close them. The glove should also be used to adjust the Air Controller, whilst
we recommend using the supplied tool to rotate the Oven Damper.
The riddle grate and ashpan are located are behind the bottom left door, which
is opened by using the supplied tool.

2. OPERATING INSTRUCTIONS
If the cook stove is being used primarily to heat the room, we recommend
leaving the bolster lids open, allowing heat from the hotplate to radiate into the
room.

2. 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 cook 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 within the Installation part of this manual.
FUEL
Your ESSE cook stove has been designed to burn wood logs. Burning wood logs
within your ESSE cook 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 cook 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
cook 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
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.

2. OPERATING INSTRUCTIONS
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 300mm,
and a diameter / width of 80mm.
LIGHTING YOUR ESSE COOK STOVE
When your ESSE cook 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 cook 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 cook 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 Ironheart, ensure
that the Air Controller is fully open (Pushed to
the left) and that the Oven Damper is also fully
opened (Fully rotated anticlockwise). If
required, the Flue Damper can also be opened,
by pushing the lever to the rear of the
appliance.

2. OPERATING INSTRUCTIONS
Lay two small wood logs along the length of the
firebox base, and place a firelighter / tightly
rolled up newspaper on top of them. On top,
use wood kindling to create a small lattice
structure, before finally placing a small wood
log on top.
Safely light the firelighter / newspaper and
close the door, but leaving it slightly ajar. Once
the flames have established on the wood logs,
(typically within 3 –5 minutes), fully close the
door and slowly reduce the air volume, by
moving the Air Controller to the right. Continue
to use the Air Controller 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 2Kg / hour.
It is very important that your ESSE cook stove is not overfired, as this may cause
long term damage to the appliance, and invalidate your warranty.
The door should only be opened during the initial lighting / refuelling
of your ESSE cook stove. If left open during normal operation, you may
experience excessive smoke emitting into your room.
When the fire is lit within the cook stove, all controls and handles
become hot - The operating tool or glove provided should be used
when interacting with the appliance.
