Craig,
6.6.6.2 states that, Spaces that contain fuel-fired equipment shall
also comply with 6.6.6.3 or 6.6.6.4.
Section 6.6.6.3 states, Where the fuel-fired equipment is above all
occupied areas, sprinkler protection shall not be required in the
concealed space.
The fact that the furnace is above all occupied areas would then allow
for the sprinkler to be omitted, wouldn't it?

I'm a bit confused on whether sprinklers are required or not in an
attic with fuel fired equipment.
Looking at NFPA 13R, 2019 ed. it states:
6.6.6 Sprinklers shall not be required in attics,
penthouse equipment rooms, elevator machine rooms, concealed
spaces dedicated exclusively to and containing only dwelling
unit
ventilation equipment, crawl spaces, floor/ceiling spaces,
elevator shafts.... and other concealed spaces that are not
intended for living purposes or storage and do not contain
fuel-fired equipment.
This would tell me that sprinklers are required due to the
presence of fuel fired equipment, in this case a furnace.
However, section 6.6.6.1 says, When fuel-fired equipment is
present, at least one quick-response intermediate temperature
sprinkler shall be installed above the equipment.
Then section 6.6.6.3 states, Where the fuel-fired equipment is
above all occupied areas, sprinkler protection shall not be
required in the concealed space.
So, it seems to me that sprinklers will not be required since the
furnace is in that attic and above all occupied areas.
Does this sound correct?
