0 HEATER/COMPACT BOILER
Before using the appliance check that all the movable parts are in place; also remove any labels and
stickers from the glass to avoid having permanent traces remain on the surfaces.
Ensure that the electrical and hydraulic connections have been made perfectly.
Then carry out the following operations:
- Check that the hydraulic plant has been made correctly, and that the expansion
tank is sufficiently large to guarantee maximum safety. Remember that expansion
is calculated as 6 % of the total volume contained in the plant. Any damage to the
plant and/or the appliance shall not be considered as covered by the warranty. The
installation of the expansion tank in the appliance does not guarantee adequate
protection from the thermal expansion of the water in the plant.
- Connect the electrical power supply to the appliance and turn the rear switch to “1”.
- Fill up the plant by opening the cock Z (figure on right).
- During the replenishment phase do not apply over-pressure to the appliance: max
pressure 1 bar. Read the pressure as explained in paragraph 4.4.3.
- The water filling phase must take place simultaneously with the discharge of air.
Perform the bleeding operation by means of a screwdriver (to accelerate the plant
fill-up times) or a punch on valve 4 (figure on right)
- Connect the smoke outlet to the appliance: we recommend against using aluminium
tubes. Always use sealing gaskets. More details are given in paragraph 8.2 of this
use and maintenance booklet.
- Load the pellets into the tank.
- Press the “A” button to start the start up cycle, which is confirmed by the word
START appearing on the display. Press the same button once again to set the
combustion power level. Press the “B” button to adjust the set point temperature
for the water in the boiler (see par. 4.3). In the 20 minutes required for start up any
thermal power level set by the user is ignored in order to meet the correct loading
and suction values which have been preset by the Manufacturer. The pellets do
not drop into the burner the first time the appliance is switched on during the initial phase because the screw feeder is
empty.. As soon as the first few pellets drop into the brazier it could turn off and reset all the black bars. The word OFF
must appear on the display. At this point you can restart the start up phase knowing that it will be successful.
- Check the pressure inside the appliance once again and if required, bleed air bubbles from the special valve.
CAUTION: The start up phase lasts 20 minutes.
CAUTION: The system circulating pump starts as soon as the temperature in the boiler reaches 61°C.
CAUTION: If the appliance does not start up correctly check that the brazier and heating element are clean.
It is extremely important to ensure that the conduit for the heating element is clean; there must be
no scale or dust accumulations. Clean using a strong vacuum cleaner.
