See NFPA 2022 9.5.2.1.1 (2) It states that the coverage area is defined by
determining the perpendicular distance to the branch lines on either side, then
using the larger of twice the distance to calculate the coverage area. So the
14' dimension is the one that must be used.

I think Todd is right too. No different than finding the spacing of a head
next to the wall. Use the greater distance of either 2x the distance of the
head off the wall or the spacing between that head and the next head in the
line.

I know this isn't a system riser but the concept is the same. Maybe reach out
to BlazeMaster and see what they say.
