COMMISSIONING

m
CAUTION
The commissioning and initial start-up operations
must be carried out ONLY by professionally qualified
personnel who must follow the indications provided
in the INSTALLATION AND MAINTENANCE INSTRUC-
TIONS.
7.1

Preliminary operations

Before commissioning the appliance, check that:
– the fuel, thermal system and water circuit valves are open
– there is sufficient fuel in the tank
– the system pressure, as shown on the pressure gauge (A)
when the system is cold, is between 1 and 1.2 bar
– the hydraulic circuit is deaerated
– the system expansion vessel pre-charge and the calorifier ex-
pansion vessel pre-charge match the required value
– the electrical connections have been made correctly
– the discharge pipes for the combustion by-products have
been made correctly
– the vents, if present, are adequately sized in relation to the
installed power and the combustion air inlet of the burner is
free (without splits)
– start the fan only in pre-ventilation mode to fill the diesel line.
Open the purge screw of the diesel filter and deaerate (purge)
the line
– arrange the deaeration of the calorifier coil
– the burner is installed and pre-adjusted as specified in this
manual and in the specific manual of the appliance
– the electrical connections of the control panel and of the
burner have been made as explained in the wiring diagrams
provided.
7.2 Deaerating the calorifier coil
m
CAUTION
For the boiler to be able to produce domestic water,
the air contained in the calorifier coil must first be
purged during commissioning.
To facilitate this operation, before starting up the appliance,
position the slot of the screw that releases the check valve (1)
horizontally. After purging all the air, put the screw back into its
original position.

7.3

Before commissioning

After having carried out the preliminary operations, perform the
following to start the boiler:
– set the room thermostat to the required temperature, or if the
system is equipped with a time programmer, check that this
is ON and set accordingly (~20° C)
– set the main system switch to "ON"
– adjust the calorifier thermostat (4) (circa 30°C)
– adjust the heating thermostat (5) to roughly 3/4 of the adjust-
ment range (circa 75°C)
– shift the appliance's main switch (8) to "1" (on) and check that
the green signalling LED (3), situated on the control panel, is
lit.
The boiler will perform the start-up phase and remain in func-
tion until the set temperatures have been reached.
If any ignition or operating anomalies occur, the boiler will run a
"LOCK-OUT" and the (PSB) button will light up red.
