Cleaning (customer) Cleaning and maintenance
Checking the thermal relief valve
Visually check the thermal relief valve. The outlet must
not drip.
Fig. 2-16: Thermally actuated relief valve
If the relief valve drips, press the red button to rinse the
valve (danger of scalding). If the relief valve still cannot
be closed tightly after being rinsed several times, it
must be cleaned by an installer (heating technician) or
replaced.
Press the red button to manually check the relief
valve. This rinses the relief valve. It is however
very likely that the seal will be damaged in the process
and thus the outlet will drip. Therefore, only carry out
the check on weekdays, never on weekends in the
cold winter, because there is probably no heating
technician available if the seal is defective.
2.5.3 Chimney
Clean flue tube
Sweep the flue duct from the flue outlet to the chimney
and remove the fly ash from the chimney with an ash
vacuum cleaner.
Fig. 2-17: Flue duct
Only sweep the ash into the chimney and not into
the boiler. Otherwise, ash will collect in the
fan housing and can block the draught fan.
Rinse the chimney's condensate drain
Check the chimney's condensate drain to make sure it
is free, as ash can block the outlet. To check, rinse the
outlet with some water.
