LIGHTING IN THE RIGHT WAY
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 2 kg kindling is. Also
check what the normal and maximum weights look like.
The tiled stove is only intended for use with the door closed and it
is only then that the hot air flushing of the glass surfaces occurs.
Always open the door carefully and slowly to prevent blow back
because of the changing pressure in the stove.
The function of stoves differs depending on the draught
conditions in the chimney. Achieving the correct setting for the
combustion air damper usually takes a few attempts.
In order to obtain a good bed of embers, there should always be a
thin layer of ash and charred pieces in the tiled stove.
LIGHTING FOR THE FIRST TIME
The first time that the stove is lit, lighting should be
terminated after the initial fire has caught. This is so that
the cement that is used as sealant is able to harden. After
that the stove can be used according to the instructions
below with lighting and log feeding.
QUICK LIGHTING
It is important that the wood catches
fire quickly. Quick lighting is achieved
by opening the combustion air damper
fully or by leaving the door in the lighting
position for a moment. Smouldering, i.e.
reduced.
Wood loading
1. Open the door handle slightly and let the vacuum in the firebox
equalise for a few seconds before opening the door completely.
2. Add 2-3 logs of a combined weight
of approx 1.5-2.2 kg. One log is
placed diagonally and one or two
logs are placed parallel to the
back, see illustration to the right.
Then close the door.
3. The combustion damper must be completely open for 3-5
minutes until the logs turn black and catch fire. If you wish
for slower combustion, the supply of combustion air can now
be reduced. The conditions for controlling combustion vary
depending on the temperature in the stove and the draft in the
chimney.
4. The lowest output of 4 kW is usually obtained when the
combustion damper is 30% open and two logs are lit. In this
operating mode it is important that the combustion air damper
is fully open for the first 3-5 minutes so that the wood has the
chance to ignite fully before the supply of combustion air is
reduced. A condition of being able to control the heat output
is a thick bed of embers and a high temperature in the firebox.
When the fire has burnt down to embers is the time to add
more wood.
DEFRA exempted
The stove can be used in Smoke Control Areas. Smouldering, i.e.
reduced air supply, are prevented by blocking the combustion
damper of 4 kW output.
Lighting
If your house has mechanical exhaust air ventilation you will need
to open a window near the stove before lighting the fire. Leave
the window open for a few minutes until the fire has caught.
1. Open the controls for the combustion air fully.
2. Place some newspaper or a fire
lighter block, and approximately
2 kg kindling in the middle of the
stove. The wood should be piled
alternately across and lengthways.
3. Light the fire.
4. The hatch is set to the lighting position, that is the lower
locking hook must be hooked securely around the lock reel.
When the fire has caught fully after approx 10-15 minutes,
close the doors completely (see figures to right). The first load
of logs should not be put on until the start up fire has become
a glowing bed of embers.
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.
Kindling wood: Finely chopped wood
Length: 25-35 cm
Diameter: 3-4 cm
Weight per lighting: 2.0 kg (approx. 10 - 12 finely chopped pieces)
Feeding Wood: Chopped wood
Length: 25-35 cm
Diameter: 6-7 cm
Normal weight: 1.5 kg/hour
Max weight: 2.2 kg/hour (2-3 logs per load)
