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 logs of a combined weight of approx 1.0-1.5 kg. One log is placed 

diagonally and the other one placed parallel to the back. Then close the 
door. Leave the air inlet control completely open for approx. 5 minutes 
until the logs turn black and catch fire.

Smokeless fuel loading

When using smokeless fuel the grate shall always be in open position, this is 
reached by pulling the grate towards you. It is only when the grate is in open 
position you are able to adjust the primary inlet air control. 
1. Set the primary air control to the right, this will give maximum of air 
supply towards the grate. 
2. Close the secondary air inlet control.

3. Add 0,6 kg of briquetts on top of the glowing embers and close the door. 
4. After approx. 5 minutes when the fuel is well alight, open the door and 
place the primary air control at 50 % open, this will under normal conditions 
give you the nominal output of 4 kW. 
De-ash before refueling, refuel little and often for clean and efficient bur-
ning. Always burn new fuel at high output for a few minutes before you adjust 
the primary air control into desired setting. 

Remember not to burn with 

the primary air control at maximum for longer periods.

You must NOT burn the following

Under no circumstances may bituminous coal or petrolium based solid fuel 
briquettes be used. Neither pressure impregnated wood, painted or glued 
wood, chipboard, plastic or colour brochures be used as fuel. All these mate-
rials can create hydrochloric acid and heavy metals that are damaging both 
to the environment and the stove. Hydrochloric acid can also attack the steel 
in the chimney or the mortar in a stone built chimney.

STOve maiNTeNaNce

The glass may be come sooty with use, even if the fire is lit with dry wood 
with a moisture content of 15-20%. Wiping with dry paper is often sufficient 
when cleaning regularly. If the soot has been on the glass for longer it can 
be removed using cleaning agent or a specific soot removal agent. When 
antrhacite smokeless fuel are used and the glass air wash is reduced you will 
likely have stain on the glass, this will easily be removed with some cleaning 
agent. These cleaning agents can be purchased at your local supermarket or 
your local stove dealer.

Never use cleaning agents that contain any abrasives, these can damage the 
glass.

Ensure that no embers remain when removing ash from the stove. The ash 
must be stored in a fireproof container with a lid for for at least a week 
before being disposed of.

Also clean inside the area where the ash-pan is located, otherwise spilled ash 
can prevent the ash-pan from being fully inserted and prevent the fireplace 
door from being closed properly.

The grate and other cast iron components can be cleaned using a wirebrush.

It is important that the gaskets are checked from a combustion point of 
view, because worn gaskets reduce combustion because the stove draws 
additional air. 

 Painted parts of the stove can be cleaned with a damp cloth and, if neces-
sary, a little washing-up liquid. Damage, such as scratches, to painted parts 
can be repaired using Contura touch up paint. Contact your dealer.

Components close to the centre of the fire may need to be replaced. Examp-
les of such components are the stove cladding and grate. The life of these 
components depends on how much and in what way the stove has been used.

3.  If you wish slower combustion, the supply of air inlet can be reduced. No-

minal output of 4 kW is usually obtained when the air inlet control is set 
to 50% open and two logs are lit. In this operating mode it is important 
that the air inlet control is fully open for the first 5 minutes so that the 
wood has a chance to ignite fully before the supply of from the air inlet 
control 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.  
The conditions for controlling combustion vary depending on the tempe-
rature in the stove and the draft in the chimney.

Hearth plate glass must
be discarded as waste
material together with
pottery and porcelain

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 air supply, results 
in poor combustion and efficiency with high emission discharges and can, in 
worst-case scenarios, cause rapid gas ignition resulting in stove damage.

 

The wood’s moisture content

Fresh wood is about 50 per cent water. Some of the water circulates freely 
between the fibres and some of the water is bound in the cells. The wood 
must always be dried so that the free water evaporates. The timber is ready 
for use when the moisture content has fallen below 20 %. If wood with a 
higher moisture content is lit, a large part of the energy content of the wood 
is used boiling off the water. If the wood is damp, the combustion is also 
poor, layers of soot and tar build up in the chimney and could, at worst, lead 
to a chimney fire. In addition, it causes the glass of the stove to soot and may 
cause discomfort to those living nearby.

To ensure thoroughly dry wood, the wood should be cut in the winter and 
stored, well aired, under a roof. Never cover the wood pile with a tarpaulin to 
the ground. The tarpaulin will then act as a sealed cover and the wood will 
be prevented from drying. Always store a small amount of wood indoors for 
several days before use, so that the surface moisture has time to evaporate
