• Once the 01 MINUTES TIME-OUT parameter has been adjust-
ed, it is necessary to also adjust the 06 AUGER POWER1 pa-
rameter in the System menu / FACTORY SETTINGS by lower-
ing it 0,1 seconds at a time, this only when the burner tends to
fill up during the first phase of the ignition.
CASE 3 (PELLET SIZE TOO SMALL)
The stove will tend to erogate an excessive amount of pellets into the
combustion chamber, if the pellet size is too small.
For both the Ignition and the Work mode, when there is an excessive
amount of pellets in the burner, a large quantity of white smoke will be
produced. The flame in the combustion chamber will take some time to
appear and it will be slow and unstable.
To solve this problem it will be sufficient to reduce the amount of pellets
erogated during the ignition phase. The parameters on which one must
act are:
• 03 PRELOAD TURN ON in the System menu / VAROUS SET-
TINGS. Lower the value of the parameter (about 10 seconds) so
that there is just enough pellets in the burner to cover the hole
that interconnects with the ignition resistance.
• 04 AUGER TURN ON in the System menu / FACTORY SET-
TINGS. Lower the parameter (about 0,1 at a time) in order that
the burner does not fill up during the fixed ignition phase.
• 30 AUGER CLEANING in the System menu / FACTORY SET-
TINGS. Set the parameter (about 0,1 at a time) in order that the
burner does not fill up during the variable ignition phase.
• 05 AUGER START in the System menu / FACTORY SET-
TINGS. Lower the parameter in order that the burner does not fill
up during the variable ignition phase.
CASE 4 (PELLET SIZE TOO LARGE)
The stove will tend to erogate an insufficient amount of pellets into the
combustion chamber, if the pellet size is too large.
For both the Ignition and the Work mode, when there is an insufficient
amount of pellets in the burner, the flame will take some time to appear
or not appear at all.
In order to solve this problem it will be sufficient to increase the amount
of pellets erogated during the ignition phase. The parameters on which
one must act are:
• 03 PRELOAD TURN ON in the System menu / VARIOUS SET-
TINGS. Increase the value of the parameter (about 10 seconds)
so that there is just enough pellets in the burner to cover the hole
that interconnects with the ignition resistance.
• 04 AUGER TURN ON in the System menu / FACTORY SET-
TINGS. Increase the parameter (about 0,1 at a time) in order
that the burner does not fill up during the fixed ignition phase.
• 30 AUGER CLEANING in the System menu / FACTORY SET-
TINGS. Set the parameter (about 0,1 at a time) in order that the
burner does not fill up during the variable ignition phase.
• 05 AUGER START in the System menu / FACTORY SET-
TINGS. Increase the parameter in order that the burner does not
fill up during the variable ignition phase.
IMPORTANT: for case 3 and 4, if in future a different pellet size is used,
it would be necessary to modify the parameters again.
CONNECTION AND DESCRIPTION ON HOW A DUCTED
STOVE OPERATES
Ducted pellet stoves include, in addition to the front ventilator (F), also
ventilators dedicated for ducting warm air. There are models where there
is only one ventilator installed, these stoves are equipped with a single
hot air duct (CN), while there are other models where there are two ven-
tilators installed, these stoves are equipped with two hot air ducts (DX,
SX).
• If there is no draw in the chimney flue or a negative draw, the
contact can open and the stove goes in SIC02.
• If we have repeated SIC02 errors, after verifying with a tester
and an instrument for measuring the correct functionality of the
pressure switch, the first thing to do is to measure the draw of
the chimney flue, which should be done before the first ignition.
SIC12 (FAILED IGNITION)
The causes that can provoke this kind of error are many. Chimney flue
with an excessive or insufficient draw, pellet size too large or small, dirty
stove, dirty burner, ignition resistance broken or badly placed. Lets see
the various solutions case by case, leaving out the simple ones:
CASE 1 (EXCESSIVE DRAW)
When there is an excessive draw in the chimney flue during the ignition,
the following can occur:
The pellets ignite but the flame does not develop, impeding this way that
the smoke goes up. In the burner a hole is formed that consumes the
pellets, but that does not trigger the flame. Figure 9 will clarify the con-
cept.
To solve this kind of problem, it would be necessary to reduce the Ex-
haust Fan speed during the Ignition phase:
The main parameter to adjust is the 16 EXHAUST FAN TURN- in the
System menu / FACTORY SETTINGS.
• This parameter can be reduced by 50 RPM at a time until the
flame is present in the burner.
• After adjusting the 16 EXHAUST FAN TURN- parameter, if nec-
essary, also adjust the 17 EXHAUST FAN START parameter in
the System menu / FACTORY SETTINGS, also decreasing it
by 50 RPM at a time.
Figure 9
CASE 2 (INSUFFICIENT DRAW)
When there is an insufficient draw in the chimney flue during the ignition,
the following can occur:
The pellets ignite with great difficulty or do not ignite at all. When they
ignite, a lot of white smoke is produced before the flame appears. This is
not really a problem, it is just that the flame will appear to burn very slow-
ly.
In order to solve this kind of problem, there are two solutions:
The first would be to completely replace the chimney flue with one that
has a sufficient draw.
The second would be to increase the ignition timing, in order to allow
the smoke to reach the needed temperatures.
• For stoves the parameter on which one must act, is principally
the 01 MINUTES TIME-OUT in the System menu / FACTORY
SETTINGS.
• This parameter can be increased by 60 seconds each time until
the flame is properly developed inside the burner.
