Lighting Instructions

Possible causes of mal-
functions and how to rectify 
them

Poor draft in the stove after new installation

It is difficult to light the fire and the fire dies 

after a short time 

Abnormal amounts of soot form on the glass

Smoke odour around the stove for periods

Painted parts have become discoloured

•   Check the dimensions of the chimney so that they correspond 

to the ones stated in the installation instructions.

•   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.

This can occur when wind blows down the chimney and most of-
ten occurs when the wind is from a particular direction. Another 
reason could be that the hatch was opened when there was a lot 
of flame.

If painted parts have discoloured it is due to excessive tempera-
ture in the firebox. The reason for the excessive temperature 
can be that the maximum amount of wood has been used or that 
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 can-
not rectify yourself, contact the dealer or a chimney sweep. 
We hope that these lighting tips give you enjoyable, economical 
and problem free use of your Contura stove.

•  Check that the wood is sufficiently dry.
•   Too great a negative pressure in the house, for example when 

using a kitchen extractor fan or other mechanical ventilation. 
Open a window near the hearth 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 combus-
tion air from the room.

•  Check that the combustion air damper is open.
•   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.

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 gener-

ates a lot of smoke as a result.

•   Too low temperature in the firebox, which causes incomplete 

combustion and poor draft in the chimney.

•   Handling is not correct, for example the hatch was not in the 

lighting position for 5-10 min.

   Check the moisture content of the wood, ensure that you have 

good base embers and go through the lighting instructions one 
more time.

Sweeping

Sweeping the chimney ducts and chimney connections should 
be carried out by a chimney sweep. Sweep the stove by scrap-
ing and/or brushing. A soot vacuum cleaner is most appropriate 
however. If a chimney fire occurs or is suspected, the combus-
tion damper 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.

Warning 

•   During operation, the surfaces of the stove become very 

hot and can cause burn injury if touched.

•   Be aware of the strong heat radiated through the hatch 

glass.

•  Placing flammable material closer than the safe distance 
indicated may cause a fire.
•   Pyre lighting can cause quick gas ignition with the risk of 

damage to property and personal injury.
