5.3 Warning— Fume / smoke emissions
Properly installed with a suitable flue or chimney, operated and maintained correctly, this
appliance will not emit fumes into the dwelling. Occasional fumes when de-ashing and refuelling
may occur. However, persistent fume emission is potentially dangerous and must be investigated
by an approved / registered installer.
STOP USING THE APPLIANCE IF YOU SMELL
FUMES OR SEE SMOKE ESCAPING
If fume emission does persist, the following immediate actions should be taken:
Open doors and windows to ventilate the room
Let the fire die or extinguish and safely dispose of fuel from the appliance
Check for flue or chimney blockage, and clean if required.
Seek expert advice from your registered installer
Do not attempt to re-light the stove until the cause of the fume emission has been identified
and corrected.
5.3.1 Refuelling on to a low fire bed
If there is insufficient burning material in the fire bed 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 for ignition to prevent excessive smoke.
6 Further information for all stove owners
6.1 Reduced burning (Slow Combustion)
When wood is burnt slowly in a closed appliance (e.g.: air controls at the minimum setting), it
produces moisture and tar which will create condensation and deposits in the chimney. This
effect can be minimised by burning hard for a short period, fifteen to twenty minutes twice a day.
To avoid chimney problems, your appliance should not be burnt at a reduced burn rate without a
period of fast burning. Fast burning is when the stove is burnt with a ’lively flame’ and a higher
temperature. We strongly advise against stoking the fire with wood and reducing the air inlets
before leaving the stove to extinguish (perhaps when retiring to bed) as this can lead to a cooling
of the stove and flue, resulting in incomplete combustion, sooty deposits and high levels of
pollutant gases released into the environment.
