Poor Heat Output
Stove 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 the Gallery 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 Gallery 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 Gallery 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.
