Where can I get fitting instructions for a Diplomat Select 910 double oven?

I would like to fit my new to me oven at low level rather than eye-level, and have no instructions for guidence on clearences and ventilation. MFI is bust so I am having great problems finding the relavent infomation. I would like to build a timber carcass instead of the usual MDF unit for the oven to sit in as it will be fitted in an alcove rather than in a run of units. I want to fit a hob above too. Any idea on the whereabouts of a set of instructions, or does someone have an idea of the dimensions required?
Many thanks Vicky
