Checking for tightness on the flue side
A
1.
Check flue gas collector
A
and the
boiler body for tightness.
Danger
Escaping flue gas can lead to
a health hazard.
Check gaskets on the flue gas
collector and adjust, if
required.
Note
The gaskets can also be checked
under full load with an inspection mir-
ror. If required, remove the thermal
insulation components. Traces of
condensate on the outside of flue gas
collector
A
or on thermal insulation
components also indicate a leak.
2.
If required, flue gas collector
A
can
be tightened to a torque of 10 Nm.
Note
We recommend you check the gas-
ket roughly every 500 hours run and
if necessary retighten the nuts and
ensure that the gasket is correctly
seated.
Checking the condensate drain and the neutralising system (if
installed)
Add water to the combustion chamber.
Note
The water must flow from the conden-
sate drain without back pressure.
If necessary, clean the condensate drain
pipe again.
