Technical Question:
 
Table 8.3.2.5(c) Ratings of Sprinklers in Specified Residential Areas
This table provides the Minimum Distance from Edge of Source to Ordinary or Intermediate-Temperature Sprinkler Heads.  
If the Sprinkler Head is located at the ceiling and the heating source is at the floor (i.e. kitchen range), can you please clarify if the minimum distance also includes the vertical distance.  For example,  the top edge of the kitchen range to the ceiling is 54", if a sprinkler head is located at the ceiling in front of the range, does it comply since the sprinkler head is located a vertical distance more than the required minimum distance shown on Table 8.3.2.5(c).
