stress.
3.
Fill the trap with water and fit it to the boiler.
Do not carry out
commissioning
until the following
conditions are met:
■
Free passage through the flue gas pipes.
■
Flue system with positive pressure is gas-tight.
■
Inspection port covers checked for secure and tight
seating.
■
Apertures for ensuring sufficient combustion air sup-
ply are open and cannot be closed off.
■
Applicable regulations on installing and commission-
ing flue systems have been followed.
Danger
Leaking or blocked flue systems or an insuffi-
cient supply of combustion air cause life threat-
ening poisoning due to carbon monoxide in the
flue gas.
Ensure the flue system functions correctly. Aper-
tures for combustion air supply must not be able
to be closed off.
Prevent condensate drainage via a wind protec-
tor.
