• Please note that it is extremely important for connections
to have a degree of fl exibility. This is to prevent any
movement in the installation leading to the formation of
cracks.
• For recommended chimney draught, see «2.0 Technical
Data». For fl ue pipe dimension see “2.0 Technical Data”.
NB: The chimney’s diameter must be at least just as
big as the fl ue pipe.
NB! The minimum recommended chimney length is 3.5 m
from the fl ue pipe insert. If the draught is too strong, a fl ue
pipe damper can be installed and used to reduce the draught
How wind and weather affect the stove
The performance of the stove can be affected considerably by
the wind acting on the chimney at different strengths. It may
therefore be necessary to adjust the air supply to ensure good
combustion performance. It might also be a good idea to install
a damper in the fl ue pipe so that the chimney draught can be
regulated according to the strength of the wind.
Fog and mist can have a signifi cant impact on the chimney
draught and it might be necessary to use other combustion air
settings to ensure good performance
The importance of the chimney
The chimney is the engine that drives the fi replace and it’s
essential to have a good chimney in order for the fi replace
to function properly.
The draught in the chimney creates a vacuum in the stove.
The combustion air is also used for the airwash system that
keeps the window clear of soot.
The draught in the chimney is caused by the difference in
temperatures inside and outside the chimney. The greater
the temperature difference, the better the draught in the
chimney. It is therefore important to allow the chimney to reach
operating temperature before adjusting the air vents to restrict
combustion in the stove (a brickwork chimney takes longer to
reach operating temperature than a steel chimney).
It is particularly important to reach operating temperature
as quickly as possible on days on which the draught in the
chimney is poor due to unfavourable wind and weather
conditions. Make sure the fuel ignites as quickly as possible.
Practical tip: Chop the wood into much smaller pieces and use
an extra fi relighter.
NB: If the stove has not been used for some considerable
time, it is important to check the chimney pipe for blockage.
4.4 Fitting a fl ue pipe with a top outlet
The product is supplied from the factory with the smoke outlet
fi tted for the top outlet.
