Bono/Bono Xtra

5. SPECIAL FEATURES BONO/BONO XTRA

Xtra heat storing technology
The model Bono 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 Bono/BonoXtra the general technical approval
for operation with external 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
door glass gets sooty
too fast
stove does not get
enough combustion air
stove smells strongly
and there is smoke on
the outside surface
exhaust gas emission
while putting more
wood on the fire and
during operation
possible reason
bad chimney draught
incorrect use of the
combustion air supply lever
wood logs are too large
operating temperature was
not reached
chimney draught not sufficient
stove is sooted inside
baking phase of the varnish
stove is dusty/dirty
chimney draught no sufficient,
flue pipe connection leaky
the stove door was opened
before the wood has burnt
down to embers
solution
generally: door glasses must be cleaned with Austroflamm
glass cleaner from time to time (depending on the frequency
of use)
contact your chimney sweep (elongate chimney/draught
metering)
please operate air lever according to user's instructions (if
secondary air is closed, the door glass soots rather fast)
keep to the max. fuel quantity according to user's instruction
more fuel, use dry wood (< 15 % residual moisture), attend
air regulation
contact your chimney sweep (elongate chimney/draught
metering)
more fuel, use dry wood (< 15 % residual moisture), attend
air regulation
there may be some odour development during the first
operations
cleaning before the heating season starts!
inspect joints and seal up again if necessary
check chimney draught, examine operating - for info video

put more fuel wood into the combustion chamber only if
there are only embers left (no more visible flame)
