Cleaning
The stove, flue outlets and smoke pipes should be cleaned and inspected for deposits every year
– if necessary more often,
e.g. after the cleaning of the chimney. The chimney also has to be cleaned regularly by the chimneysweeper. Your
chimneysweeper will inform you of the necessary inspection intervals. An expert should inspect the stove annually.
5. SPECIAL FEATURES UNO Xtra
Xtra heat storing technology
The model Uno Xtra has been equipped with the unique Xtra heat storing technology. This technology is based on the
patented Heat Memory System, but also on the special flue gas guidance and the convection air which can be regulated or
shut off completely. Consequently a fast heating system is being combined with an extraordinarily efficient heat storing.
The convection air can be regulated according to demand with the attached lever (see picture). The more the convection air
outlets of the top plate are open, the faster heat but less heat storing can be reached. A closed top plate will however lead to
slow heat and longer heat storing.
Our hint: while the fire still burns let the convection air outlets open; close them after the fire has burnt down in order to reach a
steady heat emission.
Operation with external air supply
The German institute for constructional engineering (DIBT) has given the Uno Xtra the general technical approval for operation
with exteranl air supply. If the combustion air is being supplied directly to the furnace by an air-tight pipe including closing
mechanism from the outside, then the stove may be used in residential property with mechanical ventilation.
If the stove in being used like that, a multiple stove installation on the same chimney is forbidden.
This stove has been approved by the German DIBT.
problem
possible reason
solution
door glass gets sooty too fast
generally: door glasses must be cleaned with
Austroflamm glass cleaner from time to time (depending
on the frequency of use)
bad chimney draught
contact your chimney sweep (elongate chimney/draught
metering)
incorrect use of the combustion air
supply lever
please operate air lever according to user's instructions
(if secondary air is closed, the door glass soots rather
fast)
wood logs are too large
keep to the max. fuel quantity according to user's
instruction
operating temperature was not
reached
more fuel, use dry wood (< 15 % residual moisture),
attend air regulation
stove does not get enough
combustion air
chimney draught not sufficient
contact your chimney sweep (elongate chimney/draught
metering)
stove is sooted inside
more fuel, use dry wood (< 15 % residual moisture),
attend air regulation
stove smells strongly and there
is smoke on the outside
surface
baking phase of the varnish
there may be some odour development during the first
operations
stove is dusty/dirty
cleaning before the heating season starts!
inspect joints and seal up again if necessary
exhaust gas emission while
putting more wood on the fire
and during operation
chimney draught no sufficient, flue
pipe connection leaky
check chimney draught, examine operating - for info

the stove door was opened before
the wood has burnt down to
embers
put more fuel wood into the combustion chamber only if
there are only embers left (no more visible flame)
