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.
