5.4 Servicing the condensing boiler heat exchanger (optional)
The condensing boiler heat exchanger must be inspected and cleaned at appropriate
intervals depending on the operating hours and fuel quality.
Inspection and cleaning must be repeated after not more than 250 operating hours or at
least once a month. For less efficient fuels (e.g. high ash content) this work needs to be
carried out more frequently.
5.4.1 Inspecting the heat exchanger
When the boiler has cooled off:
r
Remove the top cover on the condensing boiler heat exchanger
r
Remove the inspection cover incl. cleaning system below and check the heat
exchanger for dirt
r
Place the inspection cover back on the heat exchanger and operate the flushing
device by hand (manual operation)
r
Carefully lift off the cover and check the nozzles (A) of the flushing device for blockage
(lime scale, dirt etc.)
