While enjoying my temporary retirement and not having access to a copy of 13D please consider that when evaluating the following.
Read the exceptions carefully. Does it say attic or attics without fueled equipment? Also read the definition of spaces used for living. Does an attic with equipment become living space? Make sure it's something required to cover before you find a solution. Also read the TIA carefully and consider which edition is in effect in your area. If the issue is stoves perhaps AF in an attic only is OK? Remember both incidents and the testing are open flames appliances with people expected to be in close proximity. I don't think we expect people to regularly be in close proximity to an attic furnace. AF has proven time and time again to not impede fire protection by limited incidents of negative outcomes compared to the very many systems out there, at least one I'd argue was wrongly installed and AF was specifically tested in high piled storage and found to be effective in certain tested scenarios. AF is not inherently bad, not using it wisely seems to be the issue. And for example in MN no AHJ can enforce the TIA for two reasons, we have not adopted the ed. the TIA covers and even if we had the TIA was not part of the legal adoption process so couldn't be enforced. A savvy AHJ could make a safety claim under IFC chapter 1 but a savvier contractor or FPE could show more than 50/50 is apparently the concern and the committees admittance the issue is not resolved that more testing is needed, as I understand it. So you would have a strong case if you used 50/50 over the furnace only. Even if the place burns down and the insurance company blames the contractor the intent of 13D is life safety and 10 minutes never property. And the underwriter should discover the issue during their due diligence thus making their acceptance a blessing of sorts for the subrogation issue.
