the cylinder and lower ring so that the cylinder flexes and can pass the locking. Turn the screwdriver and lift
the hat in order to lift the lower ring of the hat over the locking. Do not damage the outer edge of the burner.
5.
Clean the burner e.g. by scraping with a screwdriver. If necessary, drill the guide tube of the supply needle with
a 3 mm drill bit. It is recommended that the supply needle is cleaned once per heating season or during
maintenance with a 1.5 mm drill bit. Also check the position of the pin (approx. 52 mm from the tip of the
needle).

If required, replace the base fabric

, which is held in place by the locking spring

Clean the ionisation sensor and check the distance (approx. 41 mm from the pin to the tip of the sensor).
8.
Assemble the burner in the reverse order. Ensure that the burner is in the right position. Use the glow plug to
centre the burner during assembly. Also check the position of the supply needle guard tube. Install the
ionisation sensor carefully so that the insulation is not damaged.
