2.3.4. Replacing heating element (”Half-moon” shaped, as of May 2003):
- Unscrew hinge screw on boiler side, slightly bend out side wall of hinge.
(Fig. 59)

those described for cylindrical element.
- Attention! The electrical power of a heating element with ”fuzzy logic”
control is different from those with electromechanical control!
- Positioning the heating element. Place securing clamp in the middle of the
element.
Place upper edge of heating element at the marking of position.
