An important factor for proper fuel consumption is that the logs
are the correct size. The size of the logs should be:
Kindling:
Length: 30 - 40 cm
Diameter: 2-5 cm
Amount per fire: 6-8 pieces
Firewood (split logs):
Length: 40 cm
Diameter: Approx. 8 cm
Intervals for adding wood: Approximately every 45 - 50 minutes
Size of the fire: 1,7 kg
Amount per load: 2 pieces
5.4 First time use
Before lighting the stove, put a layer of sand/ash in the bottom
to protect the bottom plate. The sand or ash should cover the
top of the ridges.
• Light the fire as described under «5.5 Daily use».
• Light the fire for a couple of hours and ventilate any smoke
and smell from the product.
• Repeat this a couple of times.
N.B. Odours when using the fireplace for the first time.
Painted products:the fireplace may emit an irritating gas when
used for the first time, and it may smell a little. 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 smells can be detected.
Enamelled products: Condensation may form on the surface of
the fireplace the first few times it is used. This must be wiped off
to prevent permanent stains forming when the surface heats up.
5.5 Daily use
The product is intended for intermittent combustion. By
intermittent combustion one means normal use of a fireplace,
meaning that each fire should burn down to embers before new
firewood is added.
•
Open both air vents (fig. 2A and 2B). (Use a glove, for example,
as the handle can become hot.)
• Place two medium sized logs in/out on each side of the
base.
• Crumple some newspaper (or birch bark) between these and
add some kindling wood in a criss-cross pattern on top and
light the newspaper. Gradually increase the size of the wood.
• Leave the door slightly open until the logs catch fire. Close
the door and ignition vent when the firewood has ignited
and the fire is burning well.
• Then regulate the rate of combustion to the desired level of
heating by adjusting the air vent (Fig. 2B).
Nominal heat emission is achieved when the air vent is open
approximately 40% and the ignition vent closed.
5.6 Adding firewood
1. Each fire should burn down to embers before new firewood
is reloaded. Open the door slightly and allow the negative
pressure to level out prior to opening the door completely.
2. Add the wood and make sure that the air vent is fully open
for a few minutes until the wood has caught fire.
3. The air vent (fig. 2B) can be turned down once the wood has
properly ignited and is burning well.
N.B. Danger of overheating: the fireplace must never be used in
a manner that causes overheating.
Overheating occurs when there is too much wood and/or air so
that too much heat is developed. A sure sign of overheating is
when parts of the fireplace glow red. When this happens, reduce
the ventilation opening immediately.
Upon suspicion of excessive/poor draught in the chimney, seek
professional help. See also «2.0 Technical data» and «4.5 Chimney
and flue pipe» for information.
5.7 Using fireplace during the transition
from winter to spring
During a transitional period with sudden fluctuations in
temperature, negative smoke draught or under difficult wind
conditions, disturbances in the chimney draught may occur so
that the smoke gasses are not drawn out.
One should then use less firewood and have a larger opening in
the air vents so that the wood burns fresher and faster. In this
was the draught in the chimney will be maintained.
To avoid accumulated ash, it should be removed more often than
usual. See «6.2 Ash removal».
