Recommended fuels are as fellows:
The Hetas Ltd, "Three Tick" appliance approval only covers the use of the following fuels in this appliance;
Phurnacite, Phurnacite Plus, Centurion, Maxibrite, Extracite, Pureheat, Blazebrite, Taybrite, Sunbrite
(Doubles/Singles), Anthracite and Welsh Dry Steam Coal (Large/Small Nuts). Approval does not cover the use of
other fuels either alone or mixed with the suitable fuels listed above, nor does it cover instructions for the use of
other fuels.
DO NOT USE SOFT COAL.
Do not use smaller sizes than Stovesse, e.g. Beans, Peas, Grains.
Do not use petroleum based solid products such as Calco or Petrocoke.
To do so will invalidate the appliance guarantee.
Wood
Any type of wood is suitable provided it is well seasoned and has been a moisture content below 20%. This
usually implies that the timber has been stored at lest nine months in the case of softwoods, and at least eighteen
month in the case of hardwood. In cases where the moisture content is above 20%, tests show that better results
are achieved by mixing the fuels 50% wood and 50% solid fuel, although some discoloration of the glass is
likely. The coal burning setting should be used when mixed fuels are burnt. We recommend that for general
burning, wood should be split into logs of no more than 130mm (5'') diameter.
Larger logs can be used for overnight burning
Warning: Green wood must not be used, as this will greatly contribute to the creation of tar and creosote,
which may, in extreme cases, run down the chimney in liquid form. This will seriously damage both the
chimney and appliance.
Note: If you have sticky tar inside the appliance or chimney your wood is green.
Peat
Peat can be used in turf or briquette form, but again the moisture content must be low. Treat in a similar fashion
to wood, however it does produce a lot of ash.
Paper
Household refuse will burn successfully. Burn dry waste only or chimney damage will occur. DEFINITELY NO
PLASTICS.
Coal
Household coal produces a large amount of ash and smoke. If used the appliance and the chimney will require
frequent cleaning. Therefore soft house coal is not recommended.
Pre-lighting checks
Check with your installer that:
• All building work is complete.
• The chimney is sound and has been swept and is free from obstruction.
• Adequate provision for combustion air has been made, i.e. a permanent vent of at least 550mm2 per kW of
rated output above 5 kW, is fitted in the room in which the appliance is installed.
• That Building Regulations and any local by-laws have been followed during installation (see installation
instructions).
• All firebox liner panels are in place.
• That the grate is correctly fitted and moves freely.
• That the ash pan is fitted.
• For all boiler models: that the system is full of water and vented, and precautions have been taken to prevent
corrosion (see installation instructions).
• There is sufficient draw in the chimney. When the chimney is warm the draught should be between 1 - 2mm
water gauge (0.1 - 0.2mbar).
ENSURE THAT YOU HAVE READ AND UNDERSTOOD THESE INSTRUCTIONS BEFORE
LIGHTING THE FIRE.
