"A.18.104.22.168 Face Sprinklers. All face sprinklers should be located within the rack structure.
The flue spaces are generally created by the arrangement of the racks, and “walkways”
should not be considered flue spaces.
Face sprinklers must be located at transverse flues within racks. Face sprinklers are not effective if located
outside the flue space, even if they are within 18 in. (450 mm) of the rack face. Exhibit 3.43 illustrates a face
sprinkler that is not located directly in the transverse flue. Note the wood slat and pallet load just above the
sprinkler. See 22.214.171.124.1 and 126.96.36.199.1 as examples of the required location of face sprinklers."
this is what NFPA13-2016 handbook says about face sprinklers, i have searched for 188.8.131.52.1 & 184.108.40.206.1

regardless of that i have been searching for much more details about the location of face sprinkler and the clearance to commodity and racks i didn't find any drawing or a text that explains the installation!
nothing is mentioned except for this :

3 in. (75 mm) from rack uprights and no more than 18 in. (450 mm) from the aisle face of
