3. USE
TAKE NOTE:
This wood burning stove is designed to be used with the
door closed. The door must remain closed except for
refuelling.
To avoid burns, do not touch the appliance and wear gloves
to operate the controls.
The heat emitted through the glass makes it necessary to
maintain a safety clearance with any material that could be
damaged by the heat (furniture, wallpaper, woodwork, etc.).
A 2 m clearance will avoid any risk.
FUEL
Wood
Only burn air-dried logs (2 to 3 years, stored in a sheltered and
well-ventilated place) with a maximum humidity of 15 to 20%.
Preferably hardwoods (birch, hornbeam, beech, etc.).
Avoid softwoods (lime, chestnut, willow, poplar).
It is strictly forbidden to permanently use softwoods (pine, fir, etc.)
as well as the use of waste from processed wood (railway
sleepers, woodworking waste, etc.) and household scraps
(vegetables or plastics).
Never use small wood, boxes, woodchips and vine shoots as
these will lead to sudden overheating.
Lignite
Lignite briquettes can be used by themselves or with wood for
slow burning. Place the briquettes in a single layer on a bed of
embers, limited to the surface area of the grid.
TAKE NOTE:
The use of coal or its derivatives is strictly
prohibited, even on an occasional basis. This appliance must
not be used to burn domestic waste.
CONTROLS
Combustion air control
The air control regulates the combustion air flow and permits the
precise control of the fire.

Door handle
To open-close the door:
- When the appliance is cold, directly with your hands
- When the appliance is hot, with an insulating glove.
LIGHTING THE FIRE FOR THE FIRST TIME
Remove the self-adhesive labels (except for the nameplate), any
possible blocking cards, and make sure that the ash tray is empty.
Start with a small fire and gradually increase the load. This
progressive heating allows the materials to expand slowly and to

stabilise. There may be some fumes and odours, due to the
paintwork. These will gradually disappear. Do this for a few days
until normal use. Open the windows during the first hours of
operation.
When heating up for the first time, check the draught according to
the technical specifications table.
SERVICE
Lighting the fire
To light your appliance, preferably follow the fire lighting procedure
described above. This fire lighting technique makes it possible to
heat up the flue and to remove any blockages (negative pressure)
that may form when the weather is bad or cold, thereby preventing
the air from blowing back into the room when the fire is lit.
The procedure is as follows:
- Set the combustion air control to the «On» position; consult the
chapter on control devices.
- Place 2 logs on the firebox grid.
- Place the kindling wood in the shape of a tower on top of the
logs.
- Put 1 or 2 fire-lighter cubes on the wood and set alight.
- Lose the door.

TAKE NOTE: Never use petrol, alcohol or fuel-oil, etc.
Reloading
Reload the appliance once there is a good bed of embers and the
flames have gone out. Gently open the loading door, to prevent
fumes from getting out (if opening during the combustion stage) or
embers from falling. Once the wood has been loaded, close the
door.
Nominal efficiency
Adjust the controls according to the table (*). The intensity of the
fire will be determined by the amount of fuel. The correct operation
of the appliance depends on a suitable air supply.
NOMINAL LOADING
For the optimum operation, load 2 small logs of wood. Place the
logs to the back of the appliance to prevent embers from falling
out.
Performance in slumber mode
Adjust the controls according to the table (*). Do not operate the
appliance in slumber mode for long periods of time. The
temperature of the combustion gases is insufficient and, instead of
being eliminated, they condense in the flue pipe. This increases
the amount of dirt in the chimney and appliance (walls and glass).
IN THE EVENT OF AN INCIDENT
In the event of an incident in the room (fire in the chimney, fire in
the room, etc.), quickly close the loading door and all the stove
controls. Do not pour water into the firebox. Call the fire brigade.

4. MAINTENANCE - RECOMMENDATIONS

ASH REMOVAL
The ashes can be removed when the stove is operating. Regularly
empty the removable ash tray. The build-up of ashes hinders the
air flow under the grid, distorting the flow and affecting
combustion. Then replace the ash tray.
CLEANING THE FRONT AND SIDES
Do not use water, solvents or abrasive products (not even slightly)
to clean the stove, only a soft, dry cloth.
CLEANING THE GLASS WINDOW
Clean the glass when it is cold, with a damp cloth dipped in wood
ashes. The air sweep system keeps the glass as clean as
possible. However, during normal operation, there may be a slight
darkening in some areas of the glass. In slumber mode, the air
sweep is less efficient.
