plastic frame of the display. Turn the screwdriver inside those
gaps, gently separate the frame from the display (Fig. 17a).

until its holders get loose (Fig. 17). Then lift the cover and remove
it.
4. Remove the lateral panels of the stove. Unscrew bolts
fastening the panels near the front grates at the top part of the
stove (Fig. 18a) and in the front and the rear sides of the base
plate of the stove. Raise the panels and remove them (Fig. 18).
5. Open all four the inspection hatches. Unscrew pairs of M5
bolts, remove gaskets and inspection lids (Fig. 18b). Clean the
