Lighting the fire
Principle
Start the fire rather briskly to heat
up the fireplace and create a good
draught.
When the fire is lit, the flue is filled
with cold air (heavier than the smoke).
If the fire does not start vigorously
enough, the smoke will not get past
this bottleneck and the stove will
produce a draught-back.
So be generous with the kindling !

To light the stove, Stûv recommends
the upside-down fire technique, which
is more environmentally friendly
and subsequently results in better
combustion.
This technique involves placing a bed
of logs in the bottom of the stove and
lighting the fire on top of them.
The benefits :
– By placing the logs underneath, you
will considerably reduce the amount
of smoke generated on lighting the
fire, while gradually increasing the
temperature.
– Once the logs underneath have
caught fire, the gases they release
must pass through the flames. These
gases rise in temperature and are
almost entirely burnt off. The result
is less CO and less particulates !
– Using this method, you no longer
need to wait for the kindling to be
blazing before adding the logs and
there is no longer any risk of these
collapsing during combustion.
– What's more, you improve the
stove's efficiency with more
complete combustion.
Before lighting
After a period of inactivity, check
that there are no obstructions in the
system, its ducts or the air inlets and
outlets or any mechanical blockages.
Your Stûv requires air
Your Stûv needs air for combustion.
Ideally, your installation engineer will
have fitted your stove with a duct that
draws the air required for combustion
directly from outside.
If an 'open-fire' valve has been
installed, open this outside air
inlet (completely when the stove
is operating in open-fire mode or
partially - ± 20% - when operating in
closed-door mode).
If no direct outside connection has
been made, provide a sufficient
outside air inlet (with a 120 mm
diameter or a 100 cm
2
area). This air
duct must comply with all applicable
local and national regulations.
Always keep this air inlet clear.
Please note that the operation of
your stove may be affected (risk of
draught-back) if other air consuming
systems are installed in the same
room (air extractor, kitchen hood,
air conditioning system). Create
additional air inlets in the room based
on their consumption.
