I believe the code prohibits contact between untreated wood and concrete/masonry. I don’t think there is any spacing requirement. I have seen contractors coat concrete with asphalt or put felt paper between the wood and the concrete to prevent contact. I think the truss companies just put a thin metal plate between untreated trusses and the masonry/concrete bearing wall.
