Lighting in the right way
Contura i6 is intended to produce secondary heating for the accommoda-
tion. It is important that the correct amount of wood is used, especially
when lighting. If you are lighting the fire for the first time you should use
a set of scales to see how much 1.5 kg kindling is. Also check what the
normal and maximum weights look like.
The insert may only be lit with the door closed. Always open the door care-
fully and slowly to prevent blow back because of the changing pressure in
the stove.
The function of the insert differs depending on the draft conditions in the
chimney. Achieving the correct setting for the combustion air damper usu-
ally takes a few attempts.
Correctly sized wood
Note that if too little kindling is used when lighting, or if the wood is too
thickly cut, the fire box will not reach the correct operating temperature.
Incorrect lighting can lead to poor combustion with heavy sooting and may
result in the fire going out when the door is shut.
Lighting logs: Finely chopped wood
Length: 25-33 cm
Diameter: 3-4 cm
Weight per lighting: 1.5 kg (approx. 12-15 finely chopped pieces)
Feeding Wood: Split logs
Length: 25-33 cm
Diameter: 7-10 cm
Normal weight: 1.5 kg/hour (1-2 pieces per insertion)
Max amount: 2,3 kg/hour (2-3 pieces per insertion)
Important!
It is important that the wood catches fire quickly.
Quick lighting is achieved by opening the combus-
tion air damper fully or by leaving the door ajar for
a moment. Pyre lighting gives poor combustion and
produces a lot of smoke and can cause quick gas
ignition in the worst instance resulting in hearth
damage.
Lighting instructions
Lighting
If the house has mechanical ventilation, open a window near to the fire-
place prior to lighting. Leave the window open for a few minutes until the
fire has caught properly.
1. Open the combustion air damper completely.
2. Insert paper or firelighters and about 1.5 kg of thinly chopped kindling
into the firebox. Stack the wood crosswise.
3. Light the fire.
4. Set the door to the lighting position, that is the door is positioned to
create a gap of
approx 10 mm between the door and the body.
5. When the fire has caught fully after approx 10-15 minutes, close the
door completely.
6. A fresh load of logs should not be put on until the start-up fire has
become a glowing bed of embers.

Adding wood
1. Open the door a few centimetres and allow the vacuum in the firebox to
equalise for a few seconds before opening the door fully.
2. Add one or two logs with a combined weight of approx 1.5 kg. Place one
log diagonally and one parallel to the back plate. Then close the door.
The combustion damper must be completely open for 5 minutes until
the logs turn black and are burning thoroughly.
3. If slower combustion is then required, the supply of combustion air can
be reduced. The nominal output of 5 kW is obtained when the combus-
tion air damper is 50 % open and two logs are lit. In this operating
position it is important that the air intake damper is fully open for the
first 5 minutes so that the wood has time to burn properly before the
supply of combustion air is reduced. A condition for regulating the
output is a thick bed of embers and high temperature in the firebox.
When the fire has died down to embers more wood should be added.
The conditions for controlling combustion vary depending on the tem-
perature in the combustion chamber and the draft in the chimney.
