Although worded in such a way (by saying at least one sprinkler over
the equipment) that one could leap to the conclusion that the entire
space must be protected, that is not the case. As Ron indicated, the
ROP and ROC is a must read to help answer such questions. As the
following shows, the answer is quite clear.

Report on Comments A2009
13R-17 Log #3 AUT-RSS Final Action: Accept in Principle
(6.9.4 through 6.9.8)
6.9.6.1 When fuel-fired equipment is present, at least one quick
response intermediate temperature sprinkler shall be installed above
the equipment.
Committee Statement: The committee agrees that sprinklering the entire
attic is not necessary; however, the committee does not agree to
require sprinklers in
areas that have been traditionally allowed to be unprotected.

In the 2002 edition 6.8.5 states "... and other concealed spaces that
are not used or intended for living purposes or storage and do not
contain fuel-fired equipment." Meaning that if fuel fired appliances
are
located in a crawl space below the main occupancy (as an example) then
sprinklers are required throughout the crawl space.
Fast forward to 2010 edition and 6.6.6.1 "When fuel fired equipment
is
present, at least one QR intermediate temperature sprinkler shall be
installed above the equipment." I read this as a crawl space that
has a
heater (again, as an example) the entire crawl space does not need
to be
sprinklered throughout but just above the fuel-fired appliance only.
If I'm reading things correctly, my question is why? What changed to
previously require sprinklers throughout the crawl space and now just
over the fuel fired appliance? Or is my original assumption with the
2002 ed incorrect in that the intent of that section was to protect
the
fuel-fired appliance and not necessarily throughout the space it's
located?
Note that I'm not sure when 6.6.6.1 was added as my research hasn't
gotten me that far. But I'm still curious.
Thanks in advance.
