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:
oA 150mm (6’’) diameter flue is required to connect to the cooking stove.
oDo not use Decromesh –only an active flue, with a rear heat shield at
1,000mm high.
oWhen installing into an existing chimney, the appliance is required to be
fully flued right to the top of the chimney.
oEnsure that the flue is installed to the relevant standards.
oIf the appliance is installed as a freestanding appliance, it should not
support any part of the chimney.
oThe flue should be free from cracks, severe bends, voids and obstructions.
oThe flue should be connected to this one appliance only.
oNew flue must be in accordance with local regulations.
oThe flue must have a cowl to prevent any ingress of rain.
oIt is recommended the flue uses an access point for cleaning and where
it can be checked and any fallen soot removed.
oDo not fit an extractor fan in the same room as the appliance.
oBe a minimum 4m high from top of the cooker to the cowl.
NOTE
The 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.

HOT WATER
Hot Water Option
-Remove left hand side panel
-Remove rear panel
-Pull back insulation to expose outlets
-Pipes can exit side or rear of your Bakeheart
-Use hemp and paste or high temperature thread sealant to
connect to hot water jacket
-Punch out appropriate pipe outlets in panel
-Replace panels
NOTE
If Bakeheart has a hot water jacket installed, it must be connected to an
appropriate hot water service before use.
Lighting your stove prior to this will void your warranty and
damage your stove.

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” Fi BSP Female on the left hand side.
Follow general notes below.
C. 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 250L low pressure hot water output.
3. This unit is not approved for use with hydronic heating systems.
4. 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.
5. The cylinder and pipe work should be lagged to avoid heat loss.
6. The static head must not exceed 18 meters.
7. A drain cock should be fitted to the lowest part of the circuit.
8. The total water capacity of the boiler is 4 litres.
9. The system must be open vented.
10.It is recommended that the system is sealed with hemp & paste or
equivalent which can withstand temperatures exceeding 100oC

Flue Draught
The chimney can be checked before the appliance is installed with a smoke
match. If the flue doesn’t pull the smoke, it may suggest the flue needs
attention.
This test is only a guide as an apparently poor flue may improve once the
appliance is installed, lit and the flue is warmed. Once the appliance is installed
a flue draught reading should be taken as detailed below.
Two flue draught readings should be taken, one with the appliance at minimum
burning rate and one at maximum burning rate. The flue draught test hole must
be drilled in the flue pipe as close to the appliance as possible and before any
flue draught stabiliser.
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 25Pa, 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, overfiring which may damage the appliance &
invalidate the warranty.
A flue stabiliser can be fitted to reduce the draught through the appliance if the
draught may exceed 25Pa. The flue stabiliser should be fitted in the same room
as the appliance and be the same size as the flue pipe. Consult building
regulations regarding additional ventilation.
A fan flue booster can also be fitted if the flue draught is poor. This should be
fitted according to the instructions supplied with the booster. An electrical
supply will be needed.

INSTALLING THE APPLIANCE
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.)

Page 16
Important Installation Notes
oThe installation must allow access for adequate chimney sweeping and
flue cleaning.
oAvoid using bends greater than 45° to the vertical. All flue pipe sections
should be as close to the vertical as possible.
oAll joints in the flue system must be effectively sealed.
oAll 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 (AS/NZS
2918/2018).
oAir inlet grilles should be positioned so that they are not liable to blockage.
oAn air extraction device shall not be used in the same room as the
appliance unless adequate additional ventilation is provided.
oA flue cleaning hatch should be fitted to provide access for cleaning the
flue and chimney.
oCheck the appliance for soundness of seals between main components
and that all supplied parts and fittings are correctly fitted.
oEnsure the appliance is left operational and hand over the operating
instructions and operating tools supplied.
oBefore leaving the installation demonstrate the operation of the
appliance to the user. Explain all controls and flue way access for cleaning.

Page 17
COMMISSIONING THE APPLIANCE
oEnsure the flue draught is compliant with AS/NZS 2918:2018.
oCheck ventilation.
oEnsure fire bricks, baffles, and the after burner are in the correct position.
oCheck that all doors fit and seal correctly.
oIf applicable check plumbing circuit.
oCheck no extractor fan, other appliance or other flue interferes.

OPERATING INSTRUCTIONS
INTRODUCTION
Thank you for choosing an ESSE cooking stove. Please read these instructions
carefully to ensure your safety and enjoyment whilst using this product.
Correctly installed and operated, your ESSE cooking stove will provide faithful
service indefinitely. We feel certain that like countless ESSE owners since 1854,
you will be truly satisfied by the warmth and comfort it will provide and the taste
of your food cooked within its oven.
BEFORE USING YOUR COOKING STOVE
Ensure that any plastic film used to protect surfaces has been removed (e.g.
from the inside of the oven door). The hotplate has been painted at the factory
to prevent rusting and therefore will require wiping with a damp cloth and
drying with a tea towel or kitchen roll.
During the first few operations of the cook stove there may be some ticking and
fumes emitted. This is normal and part of the initial expansion & material curing
process.
