7. START-UP, IGNITION AND CHECK
7.1 Commissioning checks
Before generator commissioning it is essential to check that:
The installer has issued regular Certification of Conformity
The water plant is regularly filled with the correct level of liquid inside the OPEN or
CLOSED expansion vessel.
The hopper is filled with suitable fuel (
see chepter 4
).
7.2 Start-up
After having carried out the checks of which in point
7.1
, it is possible to start the heat
generator.
The operations to be carried out are:
1.
Activate the main switch on the board.
2.
Introduce fuel on the grid as described in attachment A, checking through the open
door, that the fuel has deposited on the first two rows.
3.
Close the firebox door.
4.
Ignite fuel as described in attachment A relative section.
5. Regulate the primary and secondary air respectively through the regulation knobs
(fig.7.7)
7.3 Regime functioning
After start-up and regulations, the heat generator functioning proceeds automatically.
7.4 Frequent heat request condition
During regime functioning, with request of hot water, the fuel conveying screw and the
comburent air are regulated by a regulation thermostat:
the screw and electric fans stop once the pre-fixed maximum temperature is reached
when the water temperature has dropped by a few degrees, the screw and the fans
automatically re-start until the subsequent reaching of the pre-fixed maximum tempera-
ture.
The heat request can also be controlled by means of an ambient thermostat (timed ther-
mostat), that must be connected to the appropriate clamps with which the control board is
equipped (see electronic control unit manual-
Attachment “A” or “B”
).
This is also a description of the ignition process and fuelling. In this case, the actions to
be taken depend on the control unit, therefore refer to its manual for further details.
See attachment “A” or attachment “B”
ATTENTON !!
FIRST IGNITION MUST BE CARRIED OUT GRADUALLY WITHOUT BRINGING
THE GENERATOR TO MAXIMUM TEMPERATURE, TO AVOID THE FIRE-
RESISTANT MATERIAL IN THE COMBUSTION CHAMBER FROM BEING DAMA-
GED. RE-START THE GENERATOR AND BRING IT TO MAXIMUM TEMPERATURE
AND, THEREFORE, AT NORMAL FUNCTIONING, ONLY AFTER COOLING.
