The wood burns up too quickly. What should I do?
Ensure that air cannot get in underneath the fuel. Move the combustion air
supply slider towards the " - " position. (The primary air supply is now closed.)
Under these conditions, the layer of ash should no longer burn bright orange/
white but red.
If there is a draught (due to strong wind), air intended as secondary air for above
the fuel may enter through the openings above the door and fl ow straight down
beneath the wood. Also slide the combustion air supply slider tighter shut.
There may be too much of a draught in your chimney, particularly if it is very high
(in excess of 8 m). Ask your supplier to fi t a check valve or damper. This may not
be possible in all cases.
Can I leave my fi re unattended?
Only do this when the appliance is burning quietly, with just a little wood, with
a closed door and with the combustion air supply slider in the centre position
between " + " and " - ". In this position, the primary air supply is closed and the
secondary/tertiary air supply is open.
• Primary air is supplied through the rear of the wood rack, just above the
bottom plate (burning fl oor).
• Secondary air is supplied through the small holes in the rear panel of the
combustion chamber.
• Tertiary air is supplied through the opening behind the glass, on the upper
side of the combustion chamber.
Do not leave children unattended while the fi re is burning.
Do I have to take any extra measures if the room I am heating has an
extractor fan (mechanical ventilation)?
If the combustion air comes from the living-room:
A fl ue gas fan is required for permanent extraction of the area in which the
fi replace is placed.
The type of fl ue gas fan depends on the capacity of the extractor system.
Always consult your installation engineer about this.
If the combustion air comes directly from outside via a direct connection:
If there is constant extraction of the room in which the fi re is located, no
additional provisions are necessary.
