Modifications/Adaptions
Modification of boiler
The boiler may need to be modified. It might for instance be necessary to
remove baffle plates or turbulators in the smoke channels. Ask your PellX dealer
for advice.
Disconnect the low effect position
The burner is normally used with two effect levels (high and low), but the low
effect level may easily be disconnected by an adjustment of the circuit board. A
big and effective boiler that produces exhaust gas temperatures exceeding
approx. 180ºC should only operate on high effect to avoid condensation
problems in the chimney. Exception: Chimneys with an insert tube can be
considered more corrosion resistant. Ask your PellX dealer for advice.
Open the control box and remove the front panel. For disconnection of the low
effect position, remove the bridge in the left upper corner of the circuit board
(see figure 2.1).
Mount the restrictor in the flame trap pipe
The burner might drop a considerable amount of non-burnt pellets in the
fireplace. The supplied restrictor should in such case be installed in the flame
trap pipe. Drill a Ø 4.5 mm hole in the pipe, opposite to the overheat protection,
48 mm up from the flange. Bend the restrictor approx. 45º and fasten it with
sheet metal screws ST 3.5x 9.5 or thread the restrictor and use M4 bolts. Adjust
the bending of the restrictor to restrict but not stop the pellets feed.
