Possible causes of malfunctions and how to
rectify them
Poor draft in the insert after new installation
• Check that the chimney length meets Contura’s recommendation, which
is at least 3.5 m.
• 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 chimney area (applies to existing chimneys). The area must
be 120–175 cm².
It is diffi cult to light the fi re and the fi re 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 insert before lighting the fire. Also
try lighting some newspaper and holding it up inside the firebox to get
the draft going.
• The supply air duct from outdoors can be partially or totally blocked.
Remove the hose and try test lighting with combustion air from the
room.
Check that the combustion air damper is in the correct position, see
the instructions
• The smoke outlet of the insert 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
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 combus-
tion and poor draft in the chimney.
• Handling is not correct, for example the door was not in the lighting
position for 15 min.
Check the moisture content of the wood, ensure that you have good base
embers and go through the lighting instructions one more time.
Smoke odour around the insert for periods
This can occur when wind blows down the chimney and most often occurs
when the wind is from a particular direction. Another reason could be that
the door was opened when there was a lot of flame.
Painted parts have become discoloured
If painted parts have discoloured it is due to excessive temperature in
the firebox. The reason for the excessive temperature can be that the
maximum amount of wood has been exceeded, inappropriate fuel has been
used (for example building waste, large quantities of finely chopped off
cuts). The warranty 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 lighting tips give you enjoyable, economical and prob-
lem free use of your Contura insert.
SWEEPING
Sweeping the chimney ducts and chimney connections should be carried out by a chimney sweep. Sweep
the cassette by scraping and/or brushing. A soot vacuum cleaner is most appropriate however.
If a chimney fire occurs or is suspected, the combustion damper and the door must be closed. If neces-
sary, contact the fire brigade to extinguish it. The chimney must always be inspected by a chimney sweep
after a chimney fire.
• During operation, certain surfaces of the insert become very hot and can cause burn injuries
if touched.
• Also, take heed of the strong heat radiated through the door glass.
• Placing flammable material closer than the safe distance indicated may cause a fire.
• Smoulder combustion can cause quick gas ignition with the risk of damage to property and
personal injury.
