Good memory, The illustrations you're looking for are in the 1996 handbook, NFPA 13D, figures A-4.3.1 (a thru e,) pages 637-641.
I understand that they are showing CPVC in a 13D system, but thats were its at.
Hope this helps.

Again thanks to all that responded. We are aware of head limitations, It's just that the ridge height is 41'-4", We don't want to give them K25 throughtout if we don't have to.
We are in the process of bidding a rather large ESFR protected warehouse, ( almost 1 million sq.ft. ).
Only 10% of the building has a roof height over 40'-0". Our question, Is it acceptable to use K25 heads for the systems with roof heights over 40'-0" & K17 heads for systems with roof heights...
