Install ceiling fan with raised box

I'm installing a ceiling fan to a box, which is mounted to the ceiling. This is an outdoor ceiling under deck application. I've followed directions precisely as shown here: http://www.drysnap.com/fankit.pdf

So I'm now looking for a fan but I cannot find one that will fit flush to the ceiling as the box has a 1/2 " height. I was thinking I could install a medallion to hide the 1/2" gap between the fan and the ceiling, but would rather not if someone has a better idea. Is there a specific type of ceiling fan mount I should be looking for or a phrase on the ceiling fan box to indicate that it will fit this situation, something like "Raised Box Mounting option" I tried adjusting the bell lower but that was a no go with the fans I've looked at ?

PS Even thought these fans are rated out door I assume they need GFI protection ? Said nothing about it in the fan installation manual.

 

If you are using a short rod, the bell will generally go up and over a 1/2" protruding pancake box. Flush mount may be a different story. Small medallion may be a way to go.

 

GFCI protection is not required on outdoor fixtures. You may put them one one if you choose.

 

Thanks guys for the clarificatin on the GFI. Also the medallion was a great suggestion. Lowes had a medallion which was a perfect fit !

 

Thanks for letting us know.
