temperature, resulting in problems in retaining stable combustion.
1. Break the main current and disconnect the Euro plugs from the burner.
2. Remove the preheater hood, loosen the screws (K)
3. Measure out which overheating protectors (T) need replacing. (A
broken overheating protector has broken conductivity.)

the overheating protector shall simply be inserted fully into its sensor
tube on the preheater.
7. Fit the preheater hood using the screws (S).
