CHECKING THE GRATE AND ASH BOX
Before ignition, clear the extra ashes and larger coals from the bottom
of the fireplace into the ash box with a soft brush or poker, for example
(
Picture 1
). If needed, empty the ash box (
Picture 2)
. Clean the
grate’s vents regularly to prevent them from getting blocked. A soft
wire brush is ideal for this. When cleaning the grate or the fire box,
set the air control lever to the ‘closed’ position (
Picture A
) with the
flue damper (if installed) open.
When the fire is burning, keep the ash
box in place and the firebox door closed.
For safety reasons, do not
handle the ash until it has cooled. Clean wood ash can be used as a
fertiliser in your garden.
ENSURING SUFFICIENT COMBUSTION AIR
About 5–10 minutes before lighting the fire, check that the flue
damper is open (
Picture 3
) and the air control lever in the ‘ ignition
and embers’ position (
Picture 4 and B
).
If you have a cooker hood
or other mechanical ventilation system, switch this off before lighting
the fire.
If the ventilation system offers the option of using a so- called
fireplace switch or forced ventilation, these options are always
recommended. Especially in modern airtight houses, it is important
to ensure an adequate supply of combustion air (approximately 10 m
3
per kilogram of burned firewood).
ENSURING ADEQUATE FLUE DRAUGHT
If the fireplace has not been used for some time, check that the flue
draught is adequate. To do so, scrunch up a piece of paper into a
loose ball, place it on the grate and light it, then close the firebox
door (
Picture 5
). If there are bright, vertical flames, the flue draught
is sufficient. If the flue is not drawing sufficient air, you can prime it
by using a hair dryer to blow warm air into it via the fireplace or a flue
clean-out.
FIREWOOD LOADS
The maximum amount of wood that may be used for one firing of the
fireplace is about 0.8 kg of wood per 100 kg of fireplace weight. For
example, in a fireplace that weighs 1,000 kg, the maximum firewood
load is 8 kg of firewood per firing. The wood load can be burned in
2–4 batches. The amount of firewood and the recommended load
sizes are given in the table on
page 3
of this operating manual. The
recommended firewood load can be exceeded by no more than one
load size as presented in the table on
page 3
.
LIGHTING THE FIRE
To light the fire, first take about one fifth of the wood from the first
load and chop it into sticks of about 1–2 cm in thickness. Place the
firewood lengthwise and crosswise on the grate in alternate layers
to encourage air flow. Finally, place the sticks that you chopped
crosswise on top of this wood and put a firestarter block below them
(
Picture 6
). Make sure that the air control lever is still in the ‘ ignition
and embers’ position (
Picture B
). Light the fire and close the fireplace
door. Keep the air control lever on ignition and embers position until
the load has ignited well and move the air control lever to combustion
position (
Picture C
). If needed, keep the air control lever in ignition
and embers position (
Picture B
) during the whole first load burning.
In models equipped with a by-pass damper, initial draught can be
improved by opening the damper during the ignition phase (
Picture 7
).
The by-pass damper should only be kept open for about 5-10 minutes
during ignition if the draught is poor, after which it should be clo-
sed. Leaving the by-pass damper open for longer time during firing
can raise the temperature in the flue to such an extent that there is
a danger of the flue being damaged through overheating, or even of
causing a fire.
The door will be hot during heating and for a long time after the fire
has gone out. Be careful with the hot door and only touch the handle
and the air control lever. If necessary, use a heat-resistant glove.
ADDING FIREWOOD
When the previous full load has almost burned down to coals and you
can only see small but distinct flames, you may add more wood. Es-

avaa tulipesän luukkua hieman raolleen. To prevent smoke from ente-
ring the room when adding wood, first open the firebox door a little.
Wait a few seconds for the air flow from the room into the firebox
to settle down, and then open the firebox door fully.
Be very careful
when opening the firebox door to avoid hot embers from falling out
onto the floor.
If needed, move the air control lever to ignition and
embers position (
Picture B
) after adding a new load, to make sure
proper ignition of the new load.
If the fireplace is equipped with a by-pass damper, it is a good idea
to use it when adding more wood (
Picture 7
). Open the by-pass
damper a moment before adding more wood and close it after you
have added the wood and closed the firebox door. When adding more
wood, it is also a good idea to momentarily use forced ventilation, if
you have the opportunity to do so.
When doing this, place two pieces of wood at the base of the fire-
box, with their ends towards the door, and load the remaining pieces
of wood in a tight formation on top. Do not push the wood against
the back wall of the firebox. Make sure to place the wood underneath
the secondary air gap (
Picture 8
). The recommended number of
additional loads for normal use is 1–3.
The firebox door must normally be kept closed when the fireplace
is in use. Exceptions to this are when lighting the fire, adding wood or
stoking the embers at the end of combustion, as described in these
instructions.
END OF FIRING
When the last firewood load has burned down to the embers, move the
air control lever to the ‘ignition and embers’ position (
Picture 9 and B
).
Move the embers from the sides of the firebox onto the grate with a
poker or something similar (
Picture 10
). This way the embers will burn
efficiently. Stoke the embers a couple of times until they have finally
burned out. Then move the air control lever to the ‘closed’ position
(
Picture 11 and A
). Finally, close the flue damper (if installed;
Picture
12
). If combustion air is directly conducted from outdoors to the fire-
place, it is important to always keep the air control lever closed between
firings to avoid unnecessary cooling of the fireplace.
Reminder! Carbon monoxide is an odourless, tasteless, colourless
and toxic gas, so take special care!
It is not just the inside of the fireplace but also the exterior surfaces
that will get extremely hot when the fire is burning, and they will
remain hot for a long time afterwards. The fireplace surfaces are at
their hottest about 2–3 hours after the fire has burned out. For this
reason, and to prevent overheating, you must carefully follow the
user instructions.
Always make sure there is nothing flammable on the top or sides
of the fireplace, or in its immediate vicinity.
COOKING EQUIPMENT
Cooking equipment can only be used when the embers are dying
down or with residual heat. When the last load has burnt down to the
embers, make sure to always keep the flue damper open. Open the
fireplace door only when putting food inside the firebox or removing
it from there.
DO NOT leave the door open and always close it as soon
as you can! N.B. Carbon monoxide is an odourless, tasteless, colourless
and toxic gas!
In residual heat, when the embers are completely burnt
out, you can close the flue damper.
