declining a nursing job without burning a bridge?

[NurseNancy88]

So the deal is I recieved two job offers from jobs I interviewed for.

I got called back from job 1, accepted, but have not signed anything but am "provisionally" hired waiting on criminal background check and references. Job 2 is what I really wanted, but was sure I wouldn't get a call back from them. However, they called back, I accepted that job and should be meeting with an employee specialist from HR to sign paperwork. My question is, what is the best way to go about declining job 1 without burning bridges there? Should I call the nursing director who interviewed me or the human resources manager? And what would I say to either one to not destroy any chance of getting hired by them again incase I wanted to relocate to that facility sometime in the future? Help?
