Thursday, April 11, 2024 (1:00pm - 4:00pm) (Celebrity 6-8)

Have you ever investigated a fire surrounding a solid-fuel insert in a masonry or factory built fireplace? Did you wish you knew more about how solid-fuel inserts and the fireplaces into which they are installed are listed and tested, or more importantly how they weren’t? Why do the codes and standards surrounding masonry fireplaces matter when it comes to solid-fuel inserts? Come explore the evolution and history of the listings, codes, and standards surrounding solid-fuel inserts. Understand what is tested and what is not. Look at the dozens of discrepancies and potential failure points between solid-fuel inserts and the fireplaces into which they are installed. Solid-fuel inserts are historically not tested or listed for the application where they are actually used. Get a glimpse of the new UL1390 standard (solid-fuel inserts in masonry fireplaces) and the proposed UL1391 standard (solid-fuel inserts in factory built fireplace). We will summarize and list some studies in past decades related to solid-fuel inserts and then consider the impact on future installations. Daniel Freeman has worked in the chimney and hearth industry since 2013 and holds all major certifications in his industry as well as several from the ICC. He serves at his own expense on two Standards Technical Panels with Underwriters Laboratory regarding all heating appliances and chimneys and vents. Some of these standards are specifically for solid-fuel heating appliances, factory built fireplaces, and factory built chimneys. \He has been heavily involved in writing the new UL1390 standard and debating the UL1391 standard and now offers his years of study and experience surrounding solid-fuel inserts and their improper installation for your benefit.
