STARTING THE BOILER
Set-up conditions
•
Hydraulic and electric connections made
•
External power supply isolated
•
Boiler on/off switch to “Off”
•
Hydraulic circuit filled and under pressure
Procedure
Before starting the boiler, make sure that the
air is bled from the heating circuit using the
automatic air vent located at the top of the
boiler. Note that the black dust cap on the
air vent should be left loose to allow the auto
vent to function.
1. Set the internal MCB to ON (See
"12. Circuit break-
er 3A 400 V" on page 17
, ML Section).
2. Reinstall the removed access panels, refer to
"Removal and Installation of the Access Panels" on
page 10
.
3. Provide power supply to boiler through the ex-
ternal electrical box.
4. Place boiler On/Off switch to “On”.
5. Check that the following sequence takes place :
• The indicator shows that the first stage is ac-
tivated.
• The combined thermometer and pressure
gauge indicates the rise in temperature.
• As long as the preset temperature is not
reached, one additional stage is activated
every 2 minutes, until all stages are activat-
ed.
• Once the temperature set on the control
thermostat is reached, one stage is deac-
tivated at a time every 30 seconds, until all
stages are deactivated.
6. After a few minutes of operation of the circulat-
ing pump in the system, place the On/Off switch
of the boiler (1) to Off.
7. Bleed the air from the system and adjust the
pressure to the static pressure (height: 1 bar =
10 m - 1,5 bar = 15 m) + 0,5 bar. (min. pressure:
0,8 bar). Check the pressure on the combined
thermometer and pressure gauge.
8. The boiler is now ready to operate.
9. Place the boiler On/Off switch (1) to “On”.
Follow-on Task(s)
After several days of operation, re-check
all electrical and hydraulic connections for
tightness, as well as the system operating
pressure. Correct and adjust as necessary.
