Morso 6800 Instructions For Installation And Use Manual page 30

Refuelling on to a low fire bed
If there is insufficient burning material in the firebed to light a new fuel charge, excessive
smoke emission can occur. Refuelling must be carried out onto a sufficient quantity of
glowing embers 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, overloa-
ding can cause excess smoke.
Operation with door left open
Operation with the door open can cause excess smoke. The appliance must not be ope-
rated with the appliance door left open except as directed in the instructions.
Dampers left open
Operation with the air controls or appliance dampers open can cause excess smoke. The
appliance must not be operated with air controls, appliance dampers or door left open
except as directed in the instructions
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
gases) 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 combustion should be reduced.
But always remember to make sure that there are lasting flames until the wood be-
comes 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.
