The stove door should never be opened when the stove is being fired vigorously.
Refuelling on to a low fire bed
If there is insufficient burning material in the firebed to light a new fuel charge, excessive smo-
ke emission can occur. Refuelling must be carried out onto a sufficient quantity of glowing em-
bers and ash that the new fuel charge will ignite in a reasonable period. If there are too few
embers in the fire bed, add suitable kindling to prevent excessive smoke :
Fuel overloading
The maximum amount of fuel specified in this manual should not be exceeded, overloading
can cause excess smoke.
Operation with door left open
Operation with the door open can cause excess smoke. The appliance must not be operated
with the appliance door left open except as directed in the instructions.
Once the wood has burned out, it becomes glowing charcoall. If a good layer of embers has al-
ready formed on top of a sufficient layer of ash, the stove can keep warm for a very long time
We would strongly recommend that you do not leave your stove alit at night. It
harms the environment and constitutes very poor use of the wood as the gases
in the wood do not ignite at the low temperature, but settle as soot (unburned ga-
ses) in the chimney and stove. Extreme conditions, such as poor draught in the
chimney, large quantities of wood or wet wood, may in the worst-case scenario
cause an explosive ignition.
When firing in the summer period, when there is minimal need for heat, the
combustion will be poor. The stove provides too much heat so the combusti-
on should be reduced. But always remember to make sure that there are lasting
flames until the wood becomes charcoal. If you want a weaker fire, stoke up using
less wood.
If you fire the stove using wet wood, a lot of the fuel’s thermal energy will be
spent forcing the water out of the wood, without releasing any heat to the stove.
This incomplete combustion results in a layer of soot being left in the stove, pipe
and chimney.
