5.13 Cleaning Programme “R”
= display shows R for cleaning programme
= display shows flashing dot for feed screw operation
= display shows remaining cleaning time in seconds
The cleaning programme is carried out once an hour while the
appliance is switched on. Fan speed is increased to maximum and
pellet feed rate is reduced. This blows the lighter flue ash fraction out
of the burner pot, thus improving the combustion of the less volatile
constituents in the bed of embers. The cleaning programme reduces
the required frequency of manual cleaning.
Note:
The cleaning programme does not relieve the user from
inspecting the burner pot every day or having the appliance
serviced regularly as required.
Important Note: Fuels with a high ash content can make it
necessary for the user to clean the burner pot frequently in spite
of the cleaning programme.
5.14 Fan after-run “G OFF”
= display shows “G OFF” for fan after-run (15 minutes)
Whenever the appliance is switched off it first enters the “G OFF”
mode for 15 minutes. This can also occur as a result of an internal
error or safety shutdown. The purpose of having a fan after-run
phase after switching off the appliance is to ensure that flue gases
are safely carried away and the entire fuel in the burner pot burns
away completely. The feed screw is always off during fan after-run.
This is normally the operating state in which wodtke appliances leave
the factory. If the appliance is left plugged in for more than 15
minutes after switching off, the display will change to “stand-by”,
indicating that fan after-run is over. The fan after-run phase “G OFF”
counts as operating time.
When fan after-run is over the display either shows the “stand-by
dot” or “HE OFF”, depending on whether the stove has been
switched off manually or by an external controller (“HE OFF”).
Important information:
If the appliance is switched off during the preheating programme, the ignition element
remains active for the remaining time of the preheating programme, even if the display
shows “G OFF”. This means that the pellets in the burner pot are lit even if the
preheating programme has been aborted. The purpose of this is to burn away all the
pellets left in the burner pot, so that it will be empty at the next start and the preheating
programme can start again without difficulty. This is one reason why one should never
switch off the appliance by pulling the plug or disconnecting it from the power supply!
