HPC Fire 24" to 96" CSA Certified Linear Flat Fire Pit Insert with Push Button Ignition, Natural Gas

The HPC Fire CSA Certified Linear Flat Fire Pit Insert with Push Button Ignition is a professional-grade burner system designed for custom outdoor fire features. In the Natural Gas configurations you shared, this series is available in linear flat sizes from 24" to 96", making it a strong fit for rectangular fire pit builds that need dependable ignition and a clean linear flame presentation.

Constructed from 304 stainless steel, this insert line is built for outdoor durability and corrosion resistance. HPC’s drawing for the linear flat FPPK series identifies it as CSA certified, outdoor use only, and suitable for commercial and residential use.

This series uses push button / flame sensing ignition with spark ignition by AA battery, so these versions do not require external 24VAC or 120VAC power. HPC’s installation manual also notes that trough-style installations should recess the pan lip and that the product must remain accessible for service.

For Natural Gas installations, HPC lists supply pressure at 3.5" to 7.0" W.C. The drawing also states these models are for fixed piping systems only and not for use with small tanks.
