Morso 1400 Instructions For Installation And Use Manual page 29

The stove door should normally be opened gently the first 2 - 3 centimetres, then you should
wait until the pressure has equalised before opening the door all the way. This technique will
prevent smoke from getting out, particularly when there is a poor draught.
Once the wood has burned out, it becomes glowing charcoal. If a good layer of embers has
already formed on top of a sufficient layer of ash, the stove can keep warm for a very long
time, not least due to the favourable qualities of the cast iron.
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
smoke emission can occur. Refuelling must be carried out onto a sufficient quantity of glow-
ing 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, overloading
can cause excess smoke.
Operation with door left open
Operation with the door open can cause excess smoke. The appliance must not be oper-
ated with the appliance 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.
