Supply and extract air openings of the boiler room
Supply and extract air openings of the boiler room must
not be closed. Danger of poisoning due to incomplete
combustion if the supply air openings are closed.
Exception: Your heat generator is operated independent
of room air - see chapter 1.3 auf Seite 6.
Initial commissioning / installation inspection
Initial commissioning of a newly installed heat generator
is only allowed to be carried out by a gas appliance speci-
alist. Danger of poisoning due to incorrect initial commis-
sioning! A full installation inspection must be completed,
see installation instructions.
Checking the water pressure
Check the water pressure in the heating system at regu-
lar intervals, as described in chapter 8.1 auf Seite 77.
Filling the heating system
The replacement water must be of the required quality.
The quality requirements are stated in the installation in-
structions in the “Water quality in heating systems” chap-
ter.
Maintenance, cleaning and inspection
The heat generator must be cleaned, serviced and che-
cked by a gas appliance specialist once a year. An impor-
tant precondition for economical operation and for main-
taining good air quality is the sound technical condition of
your burner system. For this purpose, an emission mea-
surement must be carried out once a year.
Damage to the system can result from failure to perform
cleaning and maintenance or incorrect cleaning and
maintenance.
• Have the heating system inspected and cleaned once
per year.
• If necessary, have the plant serviced.
• To avoid damage to the heating system, remedy faults
immediately!
