Chester Xtra
5. SPECIAL FEATURES CHESTER XTRA
Xtra heat storing technology
The model Chester 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 Chester 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
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)
