The FT.15 Ceramic Ignition Rod is a precision spark electrode engineered specifically for assembly into FlameTech’s FT.15 Single/Two-Stage Gas Burner. Constructed from glazed high-alumina ceramic, the rod is built to withstand the extreme thermal cycling and high-temperature combustion environment demanded by ceramic kilns, glass annealing ovens, and metal heat-treatment furnace applications where the FT.15 operates. The ceramic glazing insulates the internal electrode core, preventing carbon tracking and flashover while ensuring a consistent, reliable spark for ignition even under continuous 24/7 industrial duty cycles. Designed to perform reliably up to 1500°C, the rod supports instant on-demand ignition without a standing pilot flame, working in coordination with the FT.15’s sequence controller and high/low fire modulation system for dependable startup at every firing cycle. As a direct-fit spare/assembly component for the FT.15 platform, this ceramic rod is manufactured to match OEM mounting dimensions and electrode gap tolerances, ensuring drop-in compatibility and consistent ignition performance across replacement and new-build burner units.
