Recommended Fuels
This appliance has obtained approval from HETAS Ltd., for burning
–
* HETAS approved smokeless coal suitable for a closed appliance.
* Split Hard Wood logs not exceeding 350mm in length, 100mm in diameter and not exceeding
20% moisture content.
Approval does not cover the use of other fuels either alone or mixed with the suitable fuels listed
above.
Although approval covers the use of the smokeless fuels listed, the claimed rated output, has been
obtained burning a single representative smokeless fuel, under standard test conditions. However,
in the home, a variety of operating conditions can occur and the performance of the appliance may
vary to some degree with these conditions and different fuels may need to be burnt at different
rates to provide the same heat output.
The recommended fuels are Wood logs no longer than 35cms (dry, seasoned to under 20%
moisture) and solid mineral fuels (e.g. Natural smokeless fuels) Larger coal briquettes are
recommended as they concentrate less heat in one spot reducing the likelihood of damage to the
grate. Ask your local fuel merchant or consult the HETAS website for more details on these fuels.
ONLY authorised smokeless fuels (and wood logs as described above) may be used in
smoke control areas.
Do NOT burn “House coal” or any other coal which are intended for use on open fires.
Suitable coal needs to be designed for use on closed appliances. Open fires send a large amount
of heat up the chimney therefore the fuel needs to burn extremely hot in order to send heat into the
room, closed appliances are highly efficient and send little heat up the chimney therefore the fuel
does not need to burn as hot. Using open fire coal on a closed appliance will cause excessive wear
on the stove and could result in damage which will not be covered by the products warranty.
Under NO circumstances burn “petroleum coke”
or any other chemically enhanced fuel as it
will burn out the internal grate and baffle plates in a very short period of time and may damage the
stove beyond repair.
Do NOT burn wet wood,
This will give a poor heat output and will cause heavy deposits of soot
and tar to accumulate on the glass and throughout the stove and flue. The coating of soot and tar
in the chimney is volatile creating a high risk of chimney fires. A growing tree contains a high
percentage of water, the wood needs to be dried out (seasoned) before it is suitable for burning
(this can take several years). Wood logs are best stored in a stack, sheltered from the weather, in
a well ventilated area and raised off the ground. This allows the air to circulate and prevents
mildew.
Do NOT burn pallet Wood,
or any other wood that contains glue, paint or any other chemicals.
Burning such fuels may result in damage to the appliance. Any such damage will not be covered by
the manufacturer’s warranty.
