plug gap

I bought a new spark plug from my local honda shop. They told me that it was pre set. SO I called and talked to the service guy and he told me that it should be set between 24 and 28 thousands. I wanted to make sure he was correct and called back the next day before installing the plug and a different service guy told be to gap it between 30 and 36 thousand So I have a 2000 foreman es 450. Could some one confirm the correct gap for the plug?

Thanks
