Danger
Leaking or blocked flue systems, or an insuffi-
cient combustion air supply can cause life
threatening poisoning from flue gas and carbon
monoxide.
■ Ensure the flue system is in good working
order.
■ Apertures for combustion air supply must be
non-closable.
The system may only be commissioned once the fol-
lowing conditions are guaranteed:
■ Unrestricted flow in the flue gas routes.
■ Flue pipes are routed so that all casing panels are
accessible and can be removed for maintenance.
■ Flue systems are designed to be gas-tight.
Apertures for sufficient combustion air supply are
■
non-closable.
■ All current regulations on installing and commission-
ing flue systems have been observed.
