7.2.2 Cleaning the heat exchange compartment
Twice every season the heat exchange compartment
must be cleaned completely by removing the cast-
iron back plate when cold. To remove the back
plate, after having taken out the cast-iron burn pot,
proceed as follows:
A) remove the protective grid from inside the box,
unscrewing the four cross-slotted screws with
a screwdriver
;
B) remove the inspection plate stop
(Fig. 7.7);
C) remove the inspection plate unscrewing the black
knurled knob
. (Fig.7.7.1);
D) remove all pellet residuals from inside the feed pipe
with a screwdriver
(Fig.7.7.2).
The presence of condensate indicates in
¿
ltration
of water, excessive
À
ue gas cooling or the use of
poor quality pellets. The possible cause must be
identi
¿
ed so as to restore correct operation of the
appliance
After cleaning, carefully reposition all the parts that
had been removed.
