Commissioning the system

Danger
CO build-up as a result of incor-
rect burner adjustment can have
serious health implications.
Carry out a CO test before and
after work on gas appliances.
Tightness test
Gaskets on the boiler door and compo-
nents routing flue gas can be checked
during operation with an inspection mir-
ror.
If required, remove the thermal insula-
tion components.
Traces of condensate on the outside of
the flue gas collector or on thermal insu-
lation components also indicate leaks.
Note
An examination of the burner setting with
the boiler heated to operating tempera-
ture (min. 40 °C) is essential.
Also check in the partial load range.
