Got pictures? These would help, It's hard to determine the plumbing from the limited description, Randy

+1 on posting pics and/or a drawing. For what it's worth the only time a back flow preventer is required in residential boiler installations is when you connect directly to your domestic water source for make-up water. The boiler plumbing itself should not have one.
