Would anyone know please where I may obtain a User Manual for a discontinued Delonghi range/stove cooker DFS090DF?

The cooker is a 90cm, stainless steel, single oven, five burner, dual fuel (gas hob, electric oven) appliance, around 4 years old now. It has been suggested to me it's the model number above.

I'd be most grateful for your help.
