Maintenance by professional after 10000 kg
Reminder for maintenance by professional. See also user
manual.
In preparation, perform the maintenance
for 2,200 kg and 6,000 kg
For the 10,000 kg maintenance, the maintenance
work required after the consumption of 2,200 kg
and 6,000 kg of pellets must also be performed.
Check safety valve
Check the safety valve to ensure that it is closed
tightly. The outlet must not drip.
Siphon funnel
If it drips, open the safety valve with a quarter
turn of the red cap and rinse it out. Only rinse the
safety valve on a weekday, never on weekends in
a cold winter as there will probably be no heating
technician available if the valve no longer seals.
If the valve still cannot be closed tightly after
being rinsed several times, it must be cleaned or
replaced.
Buffer storage tanks with solar charging must also
be equipped with a safety valve; its seal must also
be checked.
To permit this inspection, the valve's outlet must
be routed through an exposed area, either via a
siphon funnel leading to the sewer or a pipe to the
floor (to prevent scalding).
Draught fan and fan housing
Remove the draught fan and clean it. Also clean
ash from the fan housing.
If necessary, replace the draught fan seal.
Firebed level sensor
Check the movement of the firebed level sensor
(overfill protection).
Check fill level sensor on pellet bin
and strainer in pellet bin
Remove the fill level sensor on the pellet bin. Do
not take apart the sensor itself, but open the larger
inspection cover. Use a marker to mark the cover
and the bin so that you can reinstall the cover in
the right orientation after the maintenance work.
Clean the sensor with a soft cloth.
Tap and vacuum the strainer on the inlet to the
vacuum motor.
Inspect the seal on the inspection cover and
reinstall the cover with sensor.
