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 when
the system is cold , is between 1 and 1.2 bar
– the hydraulic circuit is deaerated
– the expansion vessel pre-charge value matches the request-
ed value
– the electrical connections have been made correctly
– the discharge pipes for the combustion by-products have
been made correctly
– the vents are adequately sized in relation to the installed pow-
er 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
– 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

Before commissioning

After having carried out the preliminary operations, perform the
following to start the boiler:
– set the main system switch to "ON"
ON
– set the room thermostat to the desired temperature or, if the
system is equipped with a time programmer, check that this
is "active" and set to heat request mode.
– adjust the heating thermostat (1) to roughly 3/4 of the adjust-
ment range (corresponding to roughly 75°C)
– shift the appliance's main switch (2) 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 selected 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.
m
CAUTION
– After a "LOCK-OUT", wait roughly 30 seconds before
restoring the start-up conditions (RESET).
– To reset the start-up conditions, press the burner
Fig. 35
unlock button. Wait for the entire start-up phase to
terminate until the flame appears.
– Before starting up in pre-ventilation mode, the
burner will pre-heat the fuel (for burners equipped
with a fuel pre-heater) for roughly 2 and a half min-
utes (data referred to the Sime compatible burner).
