HPC Fire H-Flat Fire Pit Insert with Electronic On/Off Ignition, Liquid Propane, 120VAC

The HPC Fire H-Flat Fire Pit Insert with Electronic On/Off Ignition is a professional-grade burner system designed for custom outdoor fire features. In the LP 120VAC On/Off configurations you shared, this series is available in multiple rectangular flat-pan sizes from 27" x 15" up to 93" x 19", with heat outputs ranging from 115,000 BTU to 400,000 BTU. The H-burner layout is designed to provide a balanced flame pattern across the pan, making it a strong fit for custom rectangular fire pit builds.

Constructed from 18-gauge 304 stainless steel, the flat pan is built for outdoor durability and corrosion resistance. HPC notes that its flat pans are cut from 304 stainless steel sheet and sized slightly under nominal dimensions to help with installation fit.

This series features electronic On/Off ignition with flame sensing and electronic ignition operation. HPC’s EI On/Off manual states the EI Series is for outdoor use only and that installation and service must be performed by a qualified installer, service agency, or gas supplier.

For the LP versions, HPC lists supply pressure at 8.0" to 11.0" W.C. The manual also states that the EI Series is not for use with small LP tanks and must use permanent fixed piping for fuel supply. For 120VAC models, HPC specifies 120 VAC – 1 amp power, and notes that all electronic applications should use a GFCI-protected circuit.
