The question is do I need a GFCI protection ? I believe I do need one but I was told that I don't .This is a commercial warehouse with an exterior ice machine. According to 2014 code , article 210.8 (b) (4) I understand that I do need one unless I'm not understanding the article correctly or it says someone else in the code that is not necessary or maybe I'm at the wrong article . Thanks.

Greetings eococo,
The question appears to be " does an exterior receptacle need to be GFCI protected" and the answer to that is found in section 210.8(B)(4) as you stated.
(B) Other Than Dwelling Units. All 125-volt, single phase, 15- and 20-ampere receptacles installed in the locations specified in 210.8(B)(1) through (8) shall have ground-fault circuit-interrupter protection for personnel. (1) Bathrooms (2) Kitchens (3) Rooftops (4) Outdoors
Now the only exception to the general rule of 210.8(B)(4) is as follows :
Exception No. 2 to (3) and (4): Receptacles that are not readily accessible and are supplied by a branch circuit dedicated to electric snow-melting, deicing, or pipeline and vessel heating equipment shall be permitted to be installed in accordance with 426.28 or 427.22, as applicable.
Exception No. 3 to (4): In industrial establishments only, where the conditions of maintenance and supervision ensure that only qualified personnel are involved, an assured equipment grounding conductor program as specified in 590.6(B)(2) shall be permitted for only those receptacle outlets used to supply equipment that would create a greater hazard if power is interrupted or having a design that is not compatible with GFCI protection.
So the individual that told you that it is not required needs to clarify their position. or the receptacle is not 125-volt, single phase, 15- and 20-ampere, for example a 30 ampere receptacle. Keep in mind that this changes for the 2017 NEC so be aware of that.
