be less than 175 cm2, which corre-
sponds to a diameter of 150 mm. If a
damper is tted in the ue gas pipe,
there must always be at least 20 cm2of
free passage, even when the damper is
in its “closed” position. If local regula-
tions permit, two contained replaces
can be connected to the same chim-
ney. However, you must abide by local
regulations regarding the distance bet-
ween the two connections.
The woodburning stove must never
be connected to chimneys that are
also linked to a gasred heater.
An ecient stove makes high demand
on chimney properties – so always
have your local chimney sweep eva-
luate your chimney.
Connection to a brick chim-
ney
Brick a thimble into the chimney and
seat the ue gas pipe in this. The thim-
ble and ue gas pipe must not penetra-
te the chimney opening itself, but must
be ush with the inside of the chimney
duct. Joins between brickwork, the
thimble and ue gas pipe must be sea-
led with reproof material and/or bea-
ding
Connection to a steel chimney
When tting a connection from a top-
output stove directly to a steel chim-
ney, we recommend tting the chimney
tube inside the ue gas spigot so that
any soot and condensation drops into
the stove itself rather than collecting
on the exterior surface of the stove.
For connections to chimneys that are
run through ceilings, all national and
local regulations regarding distance to
ammable material must be followed.
It is important that the chimney is tted
with roof support so that the top panel
of the stove is not required to bear the
entire weight of the chimney (exces-
sive weight may cause damage on or
noise from the stove).
Draft conditions
Poor draft may result in smoke being
emitted from the stove when the door
is opened. The minimum chimney draft
to ensure satisfactory combustion in
stoves of this kind is 13 PA. However,
there will still be a risk of smoke emis-
sion if the ring door is opened during
powerful ring. Flue gas temperature at
nominal output for Panorama 273 and
Panorama XL 266 is 20° C.
Flue gas mass ow rate for Panorama
is 6 g/sec and for Panorama XL 7.5g/
sec.
The chimney draft is generated by the
dierence between the high tempera-
ture of the chimney and the low tem-
perature of the fresh air. The length and
insula-tion of the chimney, wind and
weather conditions also have an eect
on the ability of the chimney to gene-
rate appropriate under-pressure.
If the stove has not been used in a whi-
le, check that the chimney and stove
are not blocked with soot, bird nests,
etc., before using it.
Reduced draft can occur
when:
• The dierence in temperature is too
small – due to insucient chimney
insulation, for example.
• The outdoor temperature is too
high – in summer, for example.
• No wind is blowing.
• The chimney is too low and shel-
tered.
• The chimney contains false air.
• The chimney and ue gas pipe are
blocked.
• The house is too airtight (i.e. when
there is an insucient supply of
