What are the ingredients of hot compost for heating water like the Jean Pain method?

I am interested in the Jean Pain method for producing hot water and methane.

I have a large pile of lawn clippings, leaves and another large pile of cow manure.

I was wondering if cow manure is beneficial with this type of compost pile and will it add to the ability of the pile to produce heat?

Am I supposed to put something on the bottom of the pile to allow air in the pile?
