Installation sequence
Flue gas connection (cont.)
Danger
Leaking or blocked flue systems
or an insufficient supply of combustion air cause life threatening
poisoning due to carbon monoxide in the flue gas.
Ensure the flue system functions
correctly. Apertures for combustion air supply must not be able to
be closed off.
Installation
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.
■ Apertures for ensuring sufficient combustion air supply are open and cannot
be closed off.
■ Applicable regulations on installing
and commissioning flue systems have
been followed.
Condensate connection
1. Pull the condensate hose far enough
out so that no unnecessary bends are
created inside the boiler. Check the
tightness of the siphon connection.
