System start-up
You can connect control panel of the 4000 series to the
Logano G615. The commissioning process for the
different types of control panels is the same.
B
Complete the commissioning log during the start-up
process (
Æ
Chapter 11.5, page 45).
B
If the burner got contaminated as a result of
construction work, it must be cleaned before being
commissioned.
11.1
Filling the system
Refer to the table below for information about correct use
and treatment of the fill and make-up water.
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.
NOTICE:
Boiler damage from contaminated
combustion air supply.
B
Ensure there is sufficient air supply.
B
Do not use or store any chlorine-
containing cleaning agents or
halogenated hydrocarbons (e.g. in spray
cans, solvents and cleansers, paints,
adhesives) in the boiler room.
B
Do not operate the boiler when heavy dust
is present, e.g. caused by construction
work.
NOTICE:
Risk of system damage from
temperature stresses.
B
During operation, only fill the heating
system via the fill valve on the system side.
