Combustion Chamber (Baffle Plate, Thermocontrol Sensor); Burner Pot - Windhager BioWIN series Operating Manual

Care, cleaning and maintenance
3.5 Combustion chamber
Do not open the combustion chamber door during operation. Always switch the boiler off first with the
ON/OFF button and wait until burnout mode has finished. It is essential to let the combustion chamber
cool down before cleaning.
– Switch off the BioWIN with the ON/OFF button on the InfoWIN (Fig. 117) and wait until the display has gone
out.
– Raise baffle plate at rear and guide it out at a downwards pointing angle – Fig. 118, Taking out the baffle plate
and removing fly ash
– If necessary, remove fly ash from the thermocontrol sensor. The thermocontrol sensor is located in the com-
bustion chamber behind the baffle plate – Fig. 119.
Assembly:
By working through these steps in reverse order.

Burner pot

Do not open the combustion chamber door during operation. Always switch the boiler off first with the
ON/OFF button and wait until burnout mode has finished. It is essential to let the boiler cool down before
cleaning.
Before cleaning with a vacuum cleaner, check that there are no longer any embers in the combustion
residue!
Clean the burner pot if the secondary air holes or the holes in the primary air pin are partially blocked or there
is a malfunction displayed with the prompt to clean the burner pot.
– Lift out the cone (3) using the cleaning tool (1) – Fig. 120, 121, 122.
– Use the spatula to scrape off the deposits from all sides of the cone (3), however in particular on the under-
side.
– Vacuum out the burner pot, remove the primary air pin (4) and carefully clean the holes with a small screw-
driver or drill bit if necessary (holes must be clear).
– Raise the grate plate (5) from below through the base of the burner pot and remove it. Use the spatula to
scrape ash residues off the grate plate (5) and the hole in the middle.
Tip: Use water to soften hard residues, or soak the grate plate in water before scraping it clean.
– Turn the cleaning tool (1) to scrape off combustion residues in the base of the burner pot – Figs. 120, 121,
122. The pipe for the primary air pin serves as a guide for the cleaning tool – see detail in Fig. 122. Use the
spatula to scrape out the edges in the base of the burner pot until they are clean. All secondary air holes (6)
in the burner pot must be clear, clean them with a small screwdriver or drill bit if necessary.
– Use a vacuum cleaner to vacuum combustion residues out of the burner pot. Vacuum the ash out of the pri-
mary air tube (in the middle of the burner pot).
The glow ignition is located in the primary air tube so avoid shaking the burner pot violently – risk of
breakage!
