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.

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:
•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.
•The flue needs to be a minimum of 4.6m in height and terminate in
accordance with AS/NZS2918
•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.
•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.
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 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.
Any damage to the cooker or anything missing, please contact your supplier for
advice.
We ask that you dispose of any packaging in a safe responsible manner and recycle
where possible.

ELECTRIC OVENS, GRILL, AND HOTPLATE
The electric ovens work by modulating the power between the cast iron hotplate,
the top oven, and the lower oven. If both ovens and the hotplate are on, the cooker
will modulate the power to reach the selected temperatures, but if only one oven or
the hotplate is turned on it will heat up more quickly.
The cooker is designed to be used on slumber mode for the majority of the day giving
off a constant background heat and can then heat up quickly to the required cooking
temperatures when required. However the cooker can simply be used as an On/Off
appliance if required.
The cooker consumes less than 1kW/Hr in slumber
mode at a room temperature of 18°C.
The top and bottom oven are controlled thermostatically and the temperature
markings on the controls are in °C. To switch one of the ovens on, turn the
corresponding knob clockwise to the desired temperature. The indicator light will
glow red to show that the oven is heating up and will glow green when the oven has
reached selected temperature. Similarly when the control is moved to a lower
temperature the red light will flash until the oven has reached the selected
temperature, once the selected temperature is reached the LED will glow green
again. The control shows a red flashing light after the oven has been switched off to
indicate residual heat.
The top oven
This oven has a patented 3kW wrap around element and a 3kW grill element. The
grill is a full width grill and takes priority over the top oven control. The Top oven
and grill can never be on together, if the grill control is on at any position, then the
top oven will not work until it the grill is switched off.
The thermometer in the top oven door is only a guide to actual oven temperature.
The reading will be incorrect when the door is or has been opened and will recover
once the door closed.
The lower oven
This oven has a patented 3kW wrap around element and is used as a smaller capacity,
high or low temperature oven.

SAFETY POINTS
When using the oven shelves ensure they are placed correctly between the
shelf runners.
Always use oven gloves when removing food from either oven or the grill.
