This section was revised in the 2019 edition. So I took a quick look at the submitter’s reasoning for the change. It appears to me the intent is that the sprinkler is not required in your situation.

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?

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? -- Thank you, Bob Knight, CET III Fire by Knight, LLC 208-318-3057 [FIREBYKNIGHT] [https://s-install.avcdn.net/ipm/preview/icons/icon-envelope-tick-green-avg-v1.png]<http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient> Virus-free.www.avg.com<http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient> _________________________________________________________ SprinklerForum mailing list: https://lists.firesprinkler.org/list/sprinklerforum.lists.firesprinkler.org To unsubscribe send an email to [email protected]<mailto:[email protected]> _________________________________________________________ SprinklerForum mailing list: https://lists.firesprinkler.org/list/sprinklerforum.lists.firesprinkler.org To unsubscribe send an email to [email protected]<mailto:[email protected]> _________________________________________________________ SprinklerForum mailing list: https://lists.firesprinkler.org/list/sprinklerforum.lists.firesprinkler.org To unsubscribe send an email to [email protected]<mailto:[email protected]> _________________________________________________________ SprinklerForum mailing list: https://lists.firesprinkler.org/list/sprinklerforum.lists.firesprinkler.org To unsubscribe send an email to [email protected]<mailto:[email protected]>
