HPC Fire H-Flat Fire Pit Insert with Electronic On/Off Ignition, Liquid Propane, 24VAC

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 24VAC configurations you shared, this series is offered in rectangular flat-pan sizes from 27" x 15" up to 93" x 19", making it a strong fit for custom fire pit builds that need dependable ignition and a balanced flame pattern across the burner.

Constructed from 304 stainless steel, the H-Flat insert is built for outdoor durability and corrosion resistance. HPC’s documentation also states that the EI Series is for outdoor use only, and the product family is listed under the CSA Certified H-Flat Fire Pit Inserts line.

This series uses electronic On/Off ignition with flame sensing. HPC’s On/Off manual states that a wall switch is required for safety shutoff, with optional remote-control integration, and that installation and service should be handled by a qualified installer, service agency, or gas supplier.

For the 24VAC versions, HPC specifies a Class II 24VAC, 4-amp, 100W transformer and says electronic applications should use a GFCI-protected circuit. The same manual notes that the EI Series must use permanent fixed piping for fuel supply and is not for use with small LP tanks. For LP models, HPC lists supply pressure at 8.0" to 11.0" W.C.
