The HPC Fire 121" x 8" Linear Interlink Pan Insert with Electronic On/Off Ignition is a professional-grade burner system designed for custom outdoor fire features. In the exact variants you shared, this series uses a 121" x 8" interlink pan, a torpedo burner, and is available in Natural Gas or Liquid Propane with either 120VAC or 24VAC power. HPC lists the CSA Certified Linear Interlink Pan Insert series with Electronic Ignition On/Off, Torpedo burner, 120 VAC or 24 VAC, and Natural Gas or Liquid Propane options.
Constructed from 304 stainless steel, this insert is built for outdoor durability and corrosion resistance. HPC’s Linear Interlink EI drawing identifies the series as CSA certified, for outdoor use only, and suitable for commercial and residential use. The same drawing’s dimension chart lists the 121" x 8" model at 300,000 BTU with a 7-3/4" depth dimension.
This series uses electronic On/Off ignition with flame sensing and electronic hot surface ignition. HPC’s On/Off manual states that a wall switch is required for safety shutoff, with optional remote control, timer, or whole-house integration, and that installation and service should be handled by a qualified installer, service agency, or gas supplier.
These variants are available in both Natural Gas and Liquid Propane. HPC lists Natural Gas supply pressure at 3.5" to 7.0" W.C. and LP supply pressure at 8.0" to 11.0" W.C. The manual also states that the EI Series must use permanent fixed piping and is not for use with small LP tanks.
For power, HPC specifies 120 VAC – 1 amp for 120VAC models. For 24VAC models, HPC says the fire pit may not perform properly if the power supply is below 100W or if the wire size is too small, and recommends a 24VAC 100W power supply. HPC also says all electronic applications should use a GFCI-protected circuit.
