System start-up
You can connect control panels of the 4000 series to the Logano G515.
The commissioning process for the different types of control panel is the
same.
NOTICE: The boiler can be damaged through heavy dust
deposits!
▶ Do not operate the boiler where heavy dust
contamination persists, e.g. through building work
inside the boiler room.
▶ Complete the commissioning log ( Chapter 11.6, page 37).
The pH value of the boiler water increases after the heating system has been filled. After 3 – 6 months (at the time of the first service), check whether
the pH value of the boiler water has stabilized.

Commissioning the system
Observe the following when commissioning:
▶ Purge the air from your heating system via its radiators prior to
commissioning.
▶ Check that the hot gas baffle plates are inserted correctly
( Chapter 7.8.5, page 22).

Filling the system
NOTICE: Risk of system damage from temperature
stresses.
▶ During operation, only fill the heating system via the
fill valve on the system side (return).
Refer to the table below for information about correct use and treatment
of the fill and make-up water.

Start up the control panel
Please see the accompanying technical documentation for the 4000
series control panel you are using for information on how to start it up.
11.4
Initial burner start-up
▶ When commissioning the burner, follow the installation and
maintenance instructions enclosed with the burner.
▶ Fill out the commissioning log in the burner documentation.
If you notice when taking measurements for the commissioning log that
the flue gas temperature is too low for the flue pipe (risk of
condensation), you can raise the flue gas temperature
( Chapter 11.5, page 36).
