New Oil boiler installed

I had a new carrier boiler with domestic hot water installed couple days ago.
My contract/paper work states "carrier 86% efficient and energy star rated"
I review the manual and even call carrier myself and they say its 84% and not energy star.
I call up the contractor who installed it, and they said its 86% because they installed a different nozzle.

How does that sound to you?
