4.5 POOR HEAT OUTPUT
Poor heat output from your stove could mean several things. The following are typical
examples. The fuel used could be incorrect, (too wet or too dry) the flue draught may be
excessive and outside the set operational parameters. The stove may be in adequately
sized for the room in which its situated. The building fabric may be leaking and further
attention needed to prevent the heat loss. In all instances guidance should be sought
from a suitably qualified complement engineer.
4.6 ROOM VENTILATION RESTRICTED.
If purpose ventilation is provided for the safe operation of the stove then this must not
be blocked, closed or restricted in any way.
4.7 FUEL QUALITY
Only burn dry seasoned timber, soft woods have a lower heat output than hard woods.
Solid fuels vary in heat value and sulphur content therefore it is important to check with
your coal merchant as to the suitability.
4.8 DIRTY GLASS
Dirty glass is almost always caused by poor fuel quality and the incorrect use of the air
controls, always check the moisture content of the wood you are burning with a
moisture meter and if in doubt seek further guidance on how to use the stove correctly.
4.9 UN-BURNT FUEL
Insufficient air reaching fuel - adjust the air controls to supply combustion air to burn fuel
fully. Check if the ash pan is full, empty if required. Front bar/fret may be blocked, de-
ash. Check for jammed clinker or nails in grate when the fire is out and cold.
