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 flue gas
components can be checked with an
inspection mirror during operation.
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 a leak.
