Far Side Sensing: The Latest NFPA 86 Safety Requirement for Your High Capacity Ovens
The oven is the heart of any baking process. Without it, all the ingredients are just a pile of worthless dough. Like any piece of industrial equipment, ovens have evolved over the years. Some of these changes have been motivated by the need for improved productivity, baking performance, efficiency, and flexibility, while others have been driven by updates to safety codes and standards.
In the United States, the primary safety standard for ovens is the NFPA 86: Standard for Ovens and Furnaces. The NFPA 86 has a 4 year revision cycle. Just released is the 2019 edition, with an effective date of May 24, 2018. One of the updates to the 2019 edition that is of major impact to the baking industry is the requirement for ovens to have flame sensing on the opposite side from the ignition point on any burner with a flame space greater than 3 feet in length. Prior to this, traditional tunnel, tray, and brand ovens were designed with flame sensing and ignition on the same end of the burner, usually incorporated into a single assemble. This new requirement will apply to all new and upgraded burner systems. This will present a challenge to many bakers and manufacturers as their existing ovens and oven designs were not intended for this requirement.
Bakers should know solutions are available for these "classic" oven applications to meet this new NFPA 86 requirement and need not fear modernizing their ovens over concerns in meeting it. These updated NFPA 86 requirements and new tools for meeting them will be discussed.
