After a chimney fire, the chimney must be inspected by a qualified engineer before it is
used again.
14. Troubleshooting
Symptom Cause and Solution
The stove glass is black and sooty.
The glass should be wiped clean
every few days but if it is getting
excessively black then there are a
number of probably causes.
• The firewood is too wet. Only use wood with a moisture content
of 20% or less.
•
The firebox is being overloaded with too much wood. This will
cause an excess of moisture in the firebox leading to blacking of
the glass.
• Too little wood is being used from the start or the air lever has
been closed down too quickly after the fire has been lit. This
prevents the stove and chimney coming up to the proper
working temperature and causes an incomplete combustion.
•
The chimney has insufficient draw due to it being too short or
terminating in the wrong place.
• The fire is receiving insufficient combustion air caused by a
blockage or an undersized combustion air duct.
Fire is difficult to start • The moisture content of the wood is too high. Only use wood
with a moisture content of 20% or less.
•
The logs are too thick. Kindling and thinner split logs should be
used to start the fire. Bigger logs should only be used once the
stove is hot.
•
The fire is receiving insufficient air. Is the supply air control set
correctly and are the combustion air ducts free of obstructions?
• Are the chimney and connectors free of obstructions?
When adding wood, smoke is
spilled from the door opening.
•
Is the wood dry enough?
•
Has sufficient wood burnt to bring the stove and chimney to
operating temperature?
• Is the chimney correctly sized?
• Is the chimney suffering from downdraft (ie puffing smoke
during certain weather conditions). Check that the chimney
terminates sufficiently far away from trees or nearby buildings.
Fit an anti-downdraft cowl.
• Has the stove door been opened too fast?
Too fast burning / wood
consumption too high
• Were adequately sized logs used?
• Has too much wood been loaded into the firebox
• Was the air supply control set correctly and the supply of
combustion air reduced?
The overheat safety valve is
constantly running water
• Your central heating system may not need any more heat. Turn
the air controls of the stove down. Do not load more wood into
the stove.
• The thermal store may have reached its maximum temperature
but the stove is still burning. Turn down the air controls on the
stove. Turn on your central heating so that that it uses up some
