AVOID TOO LARGE A FIRE
The fire should not be too big. Large fires are uneconomic and also produce
high smoke temperatures that can damage the stove and the chimney. The
recommended amount of wood is 1.0 kg/hour and the maximum permitted
is 1,5 kg/hour and then refers to burning split birch or other broadleaf wood
with 18% moisture content. When lighting the same weight of conifer wood,
significantly higher stove temperatures are reached. The recommended
amount of anthracite or manufactured smokeless briquettes is 0,6 kg/h,
maximum amount is 0,9 kg/h. Maximum fire for long periods reduces the life
of the stove and exceeding the permitted fuel amounts can lead to damage
to parts of the stove and the warranty being invalidated.
POSSIBLE CAUSES OF OPERATIONAL
INTERFERENCE AND HOW TO RECTIFY
THEM
Poor draught in the stove after new installa-
tion
• CheckthelengthofthechimneysothatitmeetsContura’srecommenda-
tions, that is a total length of at least 3.5 metres.
• Checkthatthereisnothinginthechimneytorestrictthesmokeandthat
no nearby buildings or trees affect the winds around the chimney.
• Checktheareaofthechimney(appliestoexistingstonebuiltchimneys),
which should be 120-200 cm².
It is difficult to light the fire and the fire dies
after a short time
• Thewoodmaynotbedryenough,checkthewood.
• Anotherreasonisthattheremaybenegativepressureinthehouse,
for example when using a kitchen extractor fan or other mechanical
ventilation. Open a window near the stove before lighting the fire. Also
try lighting some newspaper and holding it up inside the stove to get the
draft going.
• Theairsupplyductfromtheoutsidemaybecompletelyorpartially
blocked. Disconnect the hose and try lighting the fire with combustion air
from the room.
• Perhapsoneorbothofthecombustiondampersareinwrongposition,
see operating instructions.
• Thesmokeoutletofthestovemaybeblockedwithsoot,whichcanoccur
after sweeping. Lift the smoke baffle out and check.
• Finallygothroughthelightinginstructionsagain.Perhapstheamountof
kindling was too small and therefore the base embers were too weak and
cold to light the next load of wood.
Abnormal amounts of soot form on the glass
when using wood
There is always a certain amount of soot on the glass and this is added to
with each lighting. Soot on the glass is caused by three things:
• Thewoodisdamp,whichcausespoorcombustionandgeneratesalotof
smoke as a result.
• Toolowtemperatureinthefirebox,whichcausesincompletecombustion
and poor draught in the chimney.
• Incorrectprocedure,thedoorwasnotinthelightingpositionforapprox-
imately 15 minutes.
Check the moisture content of the wood, ensure that you have good base
embers and go through the lighting instructions once again.
Smoke odour around the stove for
periods
This can occur when wind blows down the chimney and most often occurs
when the wind is from a particular direction. Another cause is the door was
opened when it is burning hard.
Painted parts have become
discoloured
If painted parts have discoloured it is due to an excessive temperature in the
stove. The reason for the excessive temperature can be that the maximum
amount of fuel has been exceeded, inappropriate fuel has been used (for
example building waste, large quantities of finely chopped off cuts). The war-
ranty does not cover damage of this type.
If a problem occurs that you cannot rectify yourself, contact the dealer or a
chimney sweep.
We hope that these words of advice will help you to enjoy pleasant, economic
and problem free use of your Contura stove.
SWEEPING
Sweeping the chimney ducts and chimney connections should
be carried out by a chimney sweep. The stove can be scraped
down and/or swept. A soot vacuum cleaner is most appropriate
however.
If a chimney fire occurs or is suspected, the combustion dam-
per and the door must be closed. If necessary, contact the fire
brigade to extinguish it. The chimney must always be inspected
by a chimney sweep after a chimney fire.
