1-3 loading and running the appliance
The fire is ignited in the usual way and air is automatically admitted through the air inlet flap controlled
by the relevant setting of the thermostat knob.
When the fire is established, build it up slowly by adding a small quantity of wood, take care not to
put too much wood on at once otherwise this will :-
Kill the fire.
Reduce the firebox temperature.
Create smoke.
Cause tarring.
Cause condensation.
When the combustion chamber is up to a high enough temperature, the wood oil starts to vaporise
from the wood, and creates long yellow flames.
Secondary air is drawn in to mix with these flames and this further improves the combustion.
As the wood fuel burns away it slowly decomposes leaving a light grey coloured ash.
As is the case with all fires, if it is allowed to die down too much, it will not be possible to recover it.
Try to keep topping the firebox up regularly but do not overload it so as to kill the temperature of it.
If you need to keep the appliance in for longer periods of time try topping it up with smokeless fuel
otherwise let it go out and re light it.
If your wood has a moisture content above 25%, it would an idea to mix it with expensive kiln dried
wood (which is normally sub 10% moisture) to make sure the average burning is well below 20%
moisture.
