Poor Heat Output
The stove may be too small for room. Seek advice from a qualified heating
engineer as to (kW) output required for room size. As a guideline the volume of
the room in cubic feet divided by 500 i.e. room 15’ x 15’ x 8’ would require
3.6kW approx.
Chimney and / or flue pipe restricted, room ventilation restricted.
On Installation these will have been checked but regular maintenance is
necessary as conditions can change i.e. soot build up, birds nesting, masonry fall,
dust build up or furniture blocking vents.
Poor quality fuel.
Only burn dry seasoned timber, soft woods have a lower heat output than hard
woods. Use a moisture meter. Solid fuels vary in heat value, check with your
coal merchant as to suitability.
Dirty Glass
Nearly always caused by poor fuel quality – check the moisture content of the
wood you are burning with a moisture meter.
Fire burning too low, open the air vents on the stove to create a hot fire, this
may ‘burn’ the glass clean.
If glass requires cleaning use stove glass cleaner from your supplier, only use
glass cleaner on cold glass.
DO NOT USE
abrasives or scrapers, these will scratch
the glass making tar build up harder to remove.
NEVER
spray aerosols near the
appliance when it is alight.
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.
