Yes, forgive me. I was thinking of CA requirements. Yes. it is required in the crawl space not in the attic.

    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?
