Odours when using the fireplace for the first time
When the fireplace is used for the first time, it may emit an
irritating gas which may smell slightly. This happens because
the paint dries.The gas is not toxic but the room should be
thoroughly ventilated. Let the fire burn with a high draught until
all traces of the gas have disappeared and no smoke or odours
can be detected.
5.1 Operation
NB! If the door handle is shut when the door is in the upper
position, it will be possible for the door to remain in this position
by dropping the door stopper (Fig. 15 A) into the slot at the front.
NB: The door must not be open when the fire is lit.
By loosening the screw (Fig. 15 B) and turning the door stopper
in under the handle, the door will always close unless it is being
held open.
Heating advice
NB: Logs that have been stored outdoors or in a cold room should
be brought indoors 24 hours before use to bring them up to room
temperature.
There are various ways of heating the stove but it is always
important to be careful about what you put in the stove. See the
section on "Wood quality".
Wood quality
By quality wood we mean most well-known types of wood such
as birch, spruce and pine.
The logs should be dried so that the moisture content is no more
than 20%.
To achieve this, the logs should be cut during the late winter. They
should be split and stacked in a way that ensures good ventilation.
The wood stacks should be covered to protect the logs from rain.
The logs should be brought indoors during early autumn and
stacked/stored for use in the coming winter.
Be especially careful never to use the following materials as fuel
in your fireplace:
• Household rubbish, plastic bags, etc.
• Painted or impregnated timber (which is extremely toxic).
• Laminated wooden planks.
• Driftwood
These may harm the product and are also pollutants.
NB: Never use petrol, paraffin, methylated spirit or similar liquids
to light the fire. You may cause serious injury to yourself and
damage to the product.

1,6 kg (nominal output)
Nominal heat output is achieved when the air vent is open
approx. 100% (Fig. 26 A) and the handle for the ignition vent
(Fig. 26 - 1 B) pulled out approx. 1-2 cm.
Initial lighting
• Open the air vent and ignition vent by pulling the handles
(Fig. 26 - 1 A and B) all the way out. (Use a glove or something
similar to protect your hand in case the handles are hot.)
Fig. 27
• Place two logs at the bottom of the burn chamber and pile
the kindling in layers.
• Finally, place a medium-sized log on the top of the pile.
• Place 2 or 3 briquettes or kindling sticks under the top layer
of kindling and light the fire.
• NB: The maximum height of the pile of the wood should
be just below the horizontal holes. The holes must not be
covered.
Close the ignition vent (Fig. 26 - 1 B) when the wood has
•
caught fire properly and is burning well.
• Close the door.
• You can then regulate the rate of combustion to give the heat
you want by adjusting the air vent (fig. 26- 1 A).
• Check that the afterburning (secondary combustion) starts.
This is best indicated by yellow, flickering flames in front of
the holes under the baffle.
• If the air flow is normal you will be able to shut the door and
the fire will take care of itself.
Adding firewood
Stoke the stove frequently but only add small amounts of fuel at
a time. If the stove is filled too full, the heat created may cause
extreme stress in the chimney. Add fuel to the fire in moderation.
Avoid smouldering fires as this produces the most pollution.
The fire is best when it is burning well and the smoke from the
chimney is almost invisible.
5.2 Danger of overheating
The fireplace must never be used in a manner that
causes overheating
Overheating occurs when there is too much fuel and/or too much
air so that too much heat develops. A sure sign of overheating is
when parts of the fireplace glow red. If this happens, reduce the
air vent opening immediately.
Seek professional advice if you suspect that the chimney is not
drawing properly (too much/too little draught). For further
information, see «4.0 Installation» (Chimney and flue pipe).
