The Owner's manual was very helpful. The WEGA is about 35 years old and needed repair.
Your Website is pretty good und easily to handle.

Fitting the Splash back
In some models (not provided with lid), a stainless steel splash back is supplied with the appliance. This is meant to be fitted on the rear edge of the cooker's hob. The splash back package is in the oven cavity. 1. Unpack the splash back and dispose of the packaging with due regard to safety and the environment. 2. Slide the two bayonets of the splash back into the relevant supports on the rear edge of the cooker's hob (Fig. 16). Fig. 16
Fitting the Stability Bracket
The stability bracket supplied with the cooker must be fitted by the installer (see Fig. 17). 1. Place the cooker in its intended position and mark the cooker height, taken from the top of the trivets (splashback removed). 2. Mark 720mm below the cooker height. This is the position of the stability bracket (position of the stability bracket can be either side of the counterweight, i.e. not centrally located). 3. Fix the stability bracket (using two of the provided five fixing holes) to the rear wall (see diagram). 4. Pull the cooker towards the rear wall as shown in the diagram. The stability bracket should then come into contact with the bottom panel of the cooker. Check that the stability bracket securely prevents the cooker from accidently tipping forward when a downward force is applied to the open oven door. Fig. 17
