Pellet burner GP 45 IV 14
Figure 4.3. Main module view of burner from series “GP 45 IV”.
EXPLANATION:
The reversible (self-recovering) liquid crystal thermo-sticker serves for indication of
the temperature in the zone where it is attached. This temperature indicates also the
burner operation mode and the flue gas resistance within its route to the appliance’s
chimney, to which the burner is mounted. The initial condition of the thermo-sticker is
such that all of its temperature scale zones are dark colored. When the temperature
increases the surface of the scale zones become lighter, corresponding to the
operating temperature. Increase of the temperature in this zone indicates the
necessity for cleaning of the appliance from the ash deposits and/or the flue gas
extraction line. When it cools down the sticker reverse to its previous condition and
color;
The irreversible (not recovering) liquid crystal thermo-sticker is indicator for (at least
once) overheating of the burner’s pellet inlet pipe. This sticker has single action and
when it reaches critical temperature its color changes irreversibly. At initial condition
its indication element color is white and after its critical temperature has been
reached it becomes dark.
In case that the fuel transport auger of the burner has to be supported, then a telescopic
support can be ordered, as an optional equipment to the burner, which provides availability
for adjustment of the auger tilting angle and its stable positioning (Figure 4.4).
