Electric and probe connections
Unlatch the upper cover of the boiler, lifting it upwards.
Open the panel board by undoing the five screws with a screw-
driver, and lift the top part.
Pass through the two rectangular slots on the base of the panel
board: the cables with plugs for connecting the burner; the door
opening micro-switch cable, and connect this to the electronic
board; the connecting cable to the power line, and connect this;
the fan cable, and connect this to the inverter; the cables of the
relative pumps (storage tank, system, recirculation); and the gas,
return and flow probes.
Pass the two wires to the plug through the hole on the right side
of the boiler (on the side of the pellet container), then pass the
plug through the front hole in the front of the shell of the pellet
container, and connect the plug to the burner keeping the cables
away from the door of the boiler.
Attach the micro-switch (pos. 2) to the boiler body, making sure
it fits correctly with the control plate below the bottom door.
Insert the system flow probe and the water water safety thermo-
stat in the rear pit on the boiler body above the smoke chamber.
Insert the arc contact spring and fasten the capillaries with the
fixing clip.
Put the return probe in the relative pit at the bottom of the boiler.
Insert the flue gas temperature thermocouple in the relative
sheath of the flue gas outlet nozzle.
Connect the power supply of the screw and the pellet level sen-
sor, passing the cables from the connection point on the burner
through the hole at the front of the pellet container, making sure
the cables do not touch the front door of the boiler.
Position the top shell of the boiler, moving any power cables to
the back of the boiler and attaching these with cable ties.
The screw motor must be connected with the cable which is
supplied already wired to the panel board.
To perform this connection, remove the upper protective casing
of the feeding screw motor.
Close the doors of the boiler and connect the pellet feeding
hose between the screw and the burner, securing it with the
two provided clamps.
Keep the electric cables from coming into contact with
the smoke chamber and/or parts of it or from being cut by
friction.
A silicon gasket has been fitted on the top part of the rear
plate of the boiler for this purpose.
- Apply the boiler TECHNICAL DATA plate and the LOCAL
VENTILATION REQUIREMENTS label on the right side of the
casing after having cleaned the concerned area and removed
any grease with a suitable solvent.
Remove the protective film from the plates and apply them
making sure they stick perfectly.
Do not remove the plates as they would then no longer stick.
