9.12 Inspecting and cleaning electrical components (all models)
First ensure that the mains plug has been disconnected. Inspect the run of electrical cables.
Especially make sure that cables do not pass over sharp edges or hot places and that
they show no tears or bare wire. Torn or otherwise damaged cables must be replaced. Clean
any electrical components that are covered with dust using a paint brush. Use a suitable
scraping tool to remove any corrosion on electrical contacts.
9.13 Inspecting and cleaning convection air ducts (all models)
It is advisable to inspect all convection air passages (including those beneath the side panels
and between the heat reflector plates) once a year and use a vacuum cleaner or paint brush to
clean wherever large amounts of dust have accumulated.
9.14 Inspecting and cleaning the pellet chute and temperature sensor TP (all
models)
The pellet chute that runs from the fuel hopper to the burner pot must be cleaned thoroughly
with a wire brush or the like (taking care to remove any tar, caked on dust, pellet residues,
burnt-in pellet residues) to keep it smooth, thus ensuring that pellets can easily slide into the
burner pot and dust does not accumulate on the chute. Take care not to damage temperature
sensor TP, which is located in the chute, and check with a mirror that it is free of soot and any
deposits. If necessary, and only then, dismount TP from behind and use a brush to carefully
clean it of soot, pellet dust etc. Make sure TP is remounted in the correct position and at the
correct depth (see relevant chapter in the assembly instructions).
9.15 Finishing servicing work, test run, and service reset (all models)
After completing all servicing work re-establish all connections and perform a test run. Only
when you have completed all the above-named servicing routines should you do a service reset
(counter reset) via the operating panel. Take the values of parameters “BG” (total operating
hours) and “PG” (total pellet consumption) down in a logbook after every servicing, and keep
the logbook in a safe place. In this way you will always have a record of past servicing work in
case it should ever be necessary to call a technician.
How to do a service reset after completing all work:
To do a service reset you first have to enter “PW” at menu level 1!
With the appliance switched on, do the following:
•
Press the “Menu” key; the display will then show the installed basic software (for ex. S4
002)
•
Press the “+” or “–” key repeatedly until the display shows “PW”.
•
Starting from “PW”, press the “+” and the “–” key simultaneously for 4 seconds until
the displayed value jumps back to –1.5. Now the service reset has been completed.
•
Press the “Menu” key once more or wait for 60 seconds until the appliance changes to the
operating level.
An expert tip:
Have you really cleaned the firebox, heat exchanger, all flueways, the flue gas fan and flue
connector completely and consistently? In order for a service routine to have been effective
the flue gases must be able to pass uninhibited from the burner pot all the way into the
chimney. It’s not that everything must shine afterwards, but rather that just one bottleneck
along this path can hinder the removal of flue gas and lead to malfunctioning. So it is pointless
to polish one particular place if you are careless about or completely neglect another. The entire
flue gas passage must be cleared of any obstructing material and free.
