HPC Fire H-Flat Fire Pit Insert with Push Button Ignition, Liquid Propane

The HPC Fire H-Flat Fire Pit Insert with Push Button Ignition is a professional-grade burner system designed for custom outdoor fire features. In the LP push-button configurations you shared, this series is available in rectangular flat-pan sizes from 27" x 15" up to 57" x 19", with heat outputs ranging from 115,000 BTU to 200,000 BTU. The H-burner layout is designed to deliver an even flame pattern across the pan for custom rectangular fire pit builds.

Constructed from 304 stainless steel, these inserts are built for outdoor durability and corrosion resistance. HPC’s planning drawing for the FPPK rectangular flat-pan series identifies the line as CSA certified, outdoor use only, and suitable for commercial and residential use.

This series uses push-button flame-sensing ignition with spark ignition powered by an AA battery. Because these are push-button models, the power option is listed as N/A, so they do not require 120VAC or 24VAC electrical input for operation.

For LP installations, HPC lists supply pressure at 8.0" to 11.0" W.C. The rectangular FPPK drawing also states these inserts are for fixed piping systems only and not for use with small tanks.
