SAFETY NOTES
oProperly installed, operated and maintained, this appliance will not emit
fumes into the dwelling. However, occasional fumes from de-ashing and
re-fuelling may occur.
oPersistent fume emission is potentially dangerous and must not be
tolerated. If fume emission does persist, open doors and windows to
ventilate the room. Let the fire burn out or eject and safely dispose of fuel
from the appliance. Once the fire is cold, check the flue and chimney for
blockages and clean if required. Do not attempt to relight the fire until the
cause of the fume emission has been identified and corrected.
oSeek expert advice if necessary.
oAn adequate air supply for combustion and ventilation is essential. Air
openings provided for this purpose must not be restricted.
oShould it be likely that children, aged, or infirm people approach the
appliance whilst the fire door is open, then a fireguard should be used.
oDo not to sit or stand on theappliance or use it as a ‘step-stool’ for access
to cupboards or shelves etc. above the appliance.
oAvoid the use of aerosol sprays in the vicinity of the cooking stove when
it is in operation and do not heat any unopened airtight containers.
oEnsure that precautions are taken when deep fat frying, never leave the
appliance unattended and ensure you have fire safety equipment
available, such as a fire blanket, in case of emergency.
oWhen operating the cooking stove use the tools provided and follow
these instructions carefully.
oAttention is drawn to the fact that fire cement is caustic and hands must
be washed thoroughly after use.
oThe appliance is heavy and caremust be taken during handling.
oThese instructions give a guide for the installation of the appliance but in
no way absolve the installer from responsibilities to conform to AS/NZS
Standards, in particular AS/NZS 2918:2018,relating to the installation of
solid fuel appliances. All local regulations including those referring to
national standards need to be complied with, when installing this
appliance.

GENERAL SAFETY INFORMATION
Clearances from combustible materials are 130 mm from the sides and 225 mm
from the rear for the Bakeheart, and 350mm from the sides and 125mm from
the rear for the Warmheart.
Clearances from non-combustible materials are 25mm from the rear of the cook
stove and 10mm from the side fro both the Bakeheart and the Warmheart.
It is recommended that a smoke alarm and appropriate fire safety equipment
such as a fire extinguisher and fire blanket are installed in the kitchen as a safety
precaution and also a carbon monoxide detector.
An adequate air supply for combustion and ventilation is required. A purpose
provided air vent maybe necessary. Air openings provided for this purpose must
not be restricted. An external air kit is available.

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:
oIt 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.
oVoids 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.
oTerminate at least 1m above roof level so that the chimney does not
terminate in a pressure zone.
oIf the appliance is installed as a freestanding appliance, it should not
support any part of the chimney.
oBe free from cracks, severe bends, voids, and obstructions.
oBe connected to this one appliance only.
oNew chimneys must be in accordance with local regulations.
oThe chimney must be capped to prevent ingress of rain.
oA flue/chimney access point is required so that the state of the chimney
can be checked and any fallen soot removed.
oExternal flues must be insulated to prevent heat loss.
oDo not fit an extractor fan in the same room as the appliance.
oBe a minimum 4.6m high from top of the cooker to the chimney pot.

IH500AUS-I02-180219
oIt is recommended that an inspection hatch is fitted to the chimney as
this will make future cleaning easier.
oA single wall starter length with a single to twin wall adapter will be
needed to use twin wall insulated flue. The stove will need to be moved
away from the wall to accommodate use of twin wall flue.
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 chimney can be checked before the appliance is installed with a smoke
match. If the chimney doesn’t pull the smoke, it may suggest the chimney 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 draughttest 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 remedialaction. Low flue draught symptoms: difficult

IH500AUS-I02-180219
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.
