GENERAL SAFETY INFORMATION
Please read these operating instructions carefully for full information on the
safe installation, use and care of your new ESSE appliance.
In the UK, the installer has a responsibility under the Health and Safety at
Work Act 1974 to provide for the safety of persons carrying out the
installation. Attention is drawn to the fact that fire cement is caustic and
hands must be washed thoroughly after use. The appliance is heavy and care
must be taken during handling.
Although the appliance does not contain asbestos products, it is possible
that asbestos may be disturbed in existing installations and every precaution
must be taken.
These instructions give a guide for the installation of the appliance but in no
way absolve the installer from responsibilities to conform to British
Standards, in particular BS8303 and BS6461, relating to the installation of
solid fuel appliances. All local regulations including those referring to
national and European standards need to be complied with, when installing
this appliance.
Outside of the UK, the installer must comply with all local, national &
international standards that apply. Any adjacent combustible material
should be far enough away from the appliance so as not to raise 60ºC above
the room temperature when the appliance is in operation. If necessary, any
adjoining walls should be protected from the effects of heat. Clearances
from combustible materials are 50mm from the sides and 100mm from the
rear.
It is also recommended that a smoke alarm, a carbon monoxide detector,
and appropriate fire safety equipment such as a fire extinguisher and fire
blanket are installed in the kitchen as a safety precaution, see Approved
Document J of the Building Regulations for more information.
An adequate air supply for combustion and ventilation is required. A purpose
provided air vent may be necessary, see Approved Document J of the
Building Regulations for guidance. Air openings provided for this purpose
must not be restricted.

Page 4
PLUS1-I03-060120
This appliance must be correctly installed in accordance with these
instructions by a suitably qualified person.
ESSE cannot accept responsibility for damage to persons or items due to
poor or incorrect installation of this appliance.
Due to our policy of continuous innovation, we reserve the right to adjust or
modify our product without prior notification.
Should it be likely that children, aged, or infirm people approach the
appliance whilst the fire door is open, then a fireguard manufactured in
accordance with BS 8423:2010 should be used. Also warn children not to sit
or stand on the appliance or use it as a ‘step-stool’ for access to cupboards
or shelves etc. above the appliance.
Do not let children near the oven during use to avoid the danger of burns or
injury. Use of the appliance by the elderly or infirm should be supervised.
The appliance and its accessible parts become hot
during use. Care should be taken to avoid touching
heating elements. Children less than 8 years of age
shall be kept away unless continuously supervised.
This appliance can be used by children aged from 8 years and above and
persons with reduced physical, sensory or mental capabilities or lack of
experience and knowledge if they have been given supervision or instruction
concerning use of the appliance in a safe way and understand the hazards
involved. Children shall not play with the appliance. Cleaning and user
maintenance shall not be made by children without supervision.
Unattended cooking on a hob with fat or oil can be
dangerous and may result in fire. NEVER try to
extinguish a fire with water, instead switch off the
appliance, cover the flame with a lid or use a fire
blanket.
Danger of fire: do not store items on the cooking
surfaces.

Page 5
PLUS1-I03-060120
Metallic objects such as knives, forks, spoons and lids should not be placed
on the hob surface since they can get hot.
Do not use steam cleaners to clean any part of this appliance.
This appliance can slip if placed on a raised platform.
During cooking, food naturally produces steam, which is vented away to
prevent excessive build-up within the ovens. As steam can condense to
water droplets on the cooler outer trim of the oven, it may be necessary
during cooking to wipe away any moisture with a soft cloth. This will also
help to prevent soiling and discolouration of the oven exterior by cooking
vapours.
Avoid the use of aerosol sprays in the vicinity of the cooker.
THE CLEAN AIR ACT 1993 AND SMOKE CONTROL AREAS UK ONLY
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/

CHIMNEY AND FLUE INFORMATION
The successful operation of the cooking appliance relies on the adequate
performance of the chimney to which it is connected. The following chimney
guidelines must be followed:
•It should be installed and commissioned in accordance with BS EN
15287-1:2007
•It should have an internal cross section of no less than 320cm2
(200mm dia.) (If a flue liner is used, it should be 150mm (6’’)
diameter and be made of suitable material for burning wood). A
Flue with a diameter of 150mm (6’’), is required to connect to the
cooker.
•Voids in the chimney should be avoided, as these will prevent a
steady flue draught. The appliance flue pipe should pass beyond
the narrowing of the chimney.
•Terminate at least 1m above roof level so that the chimney does
not terminate in a pressure zone.
•If the appliance is installed as a freestanding appliance, it should
not support any part of the chimney.
•Be free from cracks, severe bends, voids, and obstructions.
•Be connected to this one appliance only.
•New chimneys must be in accordance with local regulations.

Page 8
PLUS1-I03-060120
•The chimney must be capped to prevent ingress of rain.
•A flue/chimney access point is required so that the state of the
chimney can be checked and any fallen soot removed.
•External flues must be insulated to prevent heat loss.
•Do not fit an extractor fan in the same room as the appliance.
•Be a minimum 4.6m high from top of the cooker to the chimney
pot.
Note: The chimney/flue to which this appliance is being connected must be
swept and examined for soundness prior to installation. Remedial action
should be taken if required, seeking expert advice if necessary. Where the
chimney is believed to have served an open fire installation it is possible that
a higher flue gas temperature from a closed appliance may loosen deposits
that were firmly adhered, with the consequent risk of flue blockage. It is
therefore recommended that the chimney be swept a second time within a
month of regular use after installation.

FLUE DRAUGHT
The flue draught should be checked before installation to ensure that the
flue is free of obstructions.
After installation, two flue draught readings should be taken and recorded
in these instructions, one with the appliance at minimum burning rate and
one at maximum burning rate.
Minimum reading: The appliance should be lit and allowed to warm the flue
thoroughly. Close the air controls, and ensure firebox door is fully closed.
Allow the burning rate to become steady. The flue draught reading should
now be taken; the minimum required is 12 Pascals [Pa] (0.05’’ w.g.).
Maximum reading: The air controls can now be opened to allow the
appliance to burn at maximum rate. Take a flue draught reading.
Ideally, the flue draught readings should range between 12Pa, 0.12mm
(0.05’’ w.g.) and 24Pa, 2.5mm (0.1’’ w.g.). Any readings significantly outside
this range may indicate the need for remedial action. Low flue draught
symptoms: difficult to light and smoke coming into the room. High flue
draught symptoms: fuel burns away very quickly, over firing which may
damage the appliance & invalidate the warranty.
A flue stabiliser can be fitted to reduce the draught through the appliance if
the draught is too high. The flue stabiliser should be fitted in the same room
as the appliance and be the same size as the flue pipe. Consult Approved
Document J of the Building Regulations regarding additional ventilation.
UNPACKING YOUR NEW COOKER
Unpack your new ESSE Cooker, removing all of the outer packing and
accessories from the top and bottom ovens, including protective film on the
door liners. At this time please examine the cooker for any damage to the
enamel finish.
If there is any damage to the cooker or if anything is missing, please contact
your supplier for advice.
We ask that you dispose of any packaging in a safe responsible manner and
recycle where possible.

You must be aware of the following safety requirements & regulations:
This appliance shall be installed in accordance with the regulations in force
and in a well-ventilated space.
Read the instructions before installing or using this appliance.
The cooker must be installed in accordance with: All relevant British
Standards / Codes of Practice and the relevant Building / IEE regulations.
Do not use the towel rail as a lifting aid as damage will occur.
Location of the Oven
The appliance should be sited on non-combustible material.
This appliance is designed for domestic cooking only. Use for any other
purpose could invalidate any warranty or liability claim.
Flue Connection
The flue pipe used to connect the appliance to the chimney is 6’’ (150mm)
in diameter.
(The flue connection is on the top of the appliance, in the centre at the back.)
Important Notes
•The installation must allow access for adequate chimney sweeping
and flue cleaning.
•Avoid using bends greater than 45º to the vertical. All flue pipe
sections should be as close to the vertical as possible.
•All joints in the flue system must be effectively sealed.
•All flue sockets must face upwards. On completing the installation
of the appliance, the chimney, hearth and walls adjacent to the
cooker must conform to local or national regulations currently in
force. In the United Kingdom, the appropriate sections of the
Building Regulations must be conformed to.
•Air inlet grilles should be positioned so that they are not liable to
blockage.

Page 12
PLUS1-I03-060120
•An air extraction device shall not be used in the same room as the
appliance unless adequate additional ventilation is provided.
•A flue cleaning door should be fitted to provide access for cleaning
the flue and chimney.
•Check the appliance for soundness of seals between casting and
main components and that all supplied parts and fittings are
correctly fitted.
•Ensure the appliance is left operational and hand over the
operating instructions and operating tools supplied.
•Before leaving the installation, demonstrate the operation of the
appliance to the user. Explain all controls and flue way access for
cleaning.
BEFORE USING YOUR COOKER
Remove plastic protective covers from inner door panels.
The hotplate has been coated with oil at the factory to prevent rusting and
therefore will require wiping with a damp cloth and drying with a tea towel
or kitchen roll.

PLUS1-I03-060120
HOT WATER SYSTEM
A. If a boiler is fitted to this system it must be connected to a heating
system otherwise the warranty is void.
B. There are two connections, both 1” BSP Female on the left hand side.
Follow general notes below.
C. The D boiler is of mild steel construction for use on an open vented
indirect system.
D. General Notes on Water System: -
1. The cooker will produce hot water at differing rates depending
on how it is operated. Heating control is manual, no thermostat
is fitted.
2. The system must be designed to cope with loads between the
maximum and minimum output. There must be sufficient gravity
load to absorb 2.6kW low pressure hot water output.
3. A cylinder is essential for domestic hot water supply. Minimum
capacity is 135L.
4. This unit is not approved for use with hydronic heating systems.
5. Whichever system is chosen the layout must follow established
heating engineering practice. To avoid trapping air in the boiler
a 1” BSP connection must be used on the flow and return
tapping, and any reduction in pipe size thereafter being made on
a vertical rising pipe. The cooker must be level when fitted and
the flow pipe must rise from the boiler.
6. The cylinder and pipe work should be lagged to avoid heat loss.
7. The static head must not exceed 18 meters.
8. A drain cock should be fitted to the lowest part of the circuit.
9. The total water capacity of the boiler is 4 litres.
10. A heat leak radiator should be fitted to absorb any excess heat
that may be produced.
11. The system must be open vented.

The cooker is not to be grouted or sealed at the back or sides of the worktop
as if any maintenance is required the cooker will have to be pulled away from
the wall at the rear.
The cooker weighs 195kg and the floor must be capable of withstanding the
load.
Make sure the cooker is level, use packing pieces if necessary.
The cooker may require access to the boiler points (if fitted) via the left side
panel once it is installed. We also ask that a 15mm gap is provided at the rear
of the cooker and a 10 mm gap between the cooker sides and any adjoining
non-combustible work surfaces that may be fitted is provided. If these
surfaces are combustible then these clearances increase to 50mm from the
sides and 100mm from the rear.
Due to the hand crafted nature of the cooker all dimensions are ±2mm.

LIGHTING AND CONTROLLING THE FIRE
The air controls for the fire box are located on the glass and steel fire door
behind the top cast iron door of the cooker.
Figure 3 Firebox Controls
Before lighting the fire, ensure that all vermiculite bricks are in the correct
position. Ensure the air controls are in the open position by moving the
controls to the right hand position.
Open the fire door and lay two logs along the base of the fire box forming a
space between them.
Figure 4 Logs Laid in Firebox
Place a firelighter in the space and surround with a small amount of kindling.

Page 18
PLUS1-I03-060120
Figure 5 Fire Lighter and Kindling in Place
Lay a third log over the top of the space perpendicular to the other logs.
Figure 6 Final Log in Position
When you are ready to light the fire all that needs to be done is light the
firelighter.
Once the fire has been lit leave the door partially open to allow additional
airflow until the fire has become established. When the fire is established
the fire door can be fully closed. The primary air control can be moved
towards the closed position once the sooting has burnt off the brickwork.
The secondary air flow can be reduced by moving the control to the left once
the fire has become established which should be used to control the fire
during normal operation.
When refuelling the cooker it is recommended that the logs are placed
running front to back as in Figure 4 as this leads to the cleanest combustion.

Page 19
PLUS1-I03-060120
Before lighting a full fire for the first time it is recommended that 3 smaller
fires are lit first to ensure that any moisture is driven out.
COOKING ON YOUR PLUS1
The oven and hotplate are heated directly by the fire. In order to heat up the
oven and hotplate, the fire should be lit as described on page 17.
The temperature of the hotplate is graduated from the inside out, see Figure
7 for approximate temperatures. Machined base pans are essential as heat
is transferred to them via conduction.
Figure 7 Approx. Working Temps 30 Mins. After Refuelling
To increase oven temperatures, refuel the cooker, increase the burning rate
of the fuel by use of the secondary air control, and regulate to the desired
temperature.
The shelf in the bottom oven has anti-pull out stops on the ends to prevent
it from being pulled out inadvertently; to remove, pull forward until the stop
is reached, then lift at the front and pull out of the oven. Use reverse
procedure to refit. If the shelf pull straight out then it is in back to front.
If any part of the cooker begins to glow it is being
over fired. Stop use immediately and allow to cool
before further use.

Cooking in the Firebox (Optional)
If you have purchased the additional firebox cooking kit then it is possible to
cook in the firebox over the glowing embers of the fire for a barbecue effect.
The front two side bricks, on both the left and right hand side of the firebox
should be replaced with the new bricks. These bricks incorporate runners for
the wire rack.
Figure 8 Ribbed Fire Bricks in Position
ESSE appliances are designed to be run with the firebox door closed. Opening
the door for in firebox cooking (barbecue) should be done only when the fire
has died down and cooking is done over hot embers.
Opening the firebox door for long periods of time with the fire roaring will
result in enamel damage.
