HPC Fire 33" x 15" H-Flat Fire Pit Insert-HI/LO-NG/24 V/150 K BTU

The HPC Fire 33" x 15" H-Flat Fire Pit Insert with Electronic Hi/Lo Ignition is a professional-grade burner system for custom outdoor fire features. With a 33" x 15" flat pan, H-burner configuration, 24VAC power, and natural gas fuel, it is well suited for rectangular fire pits that need reliable ignition and an even flame pattern.

Constructed from 304 stainless steel, this insert is built for outdoor durability and corrosion resistance. The H-Flat EI drawing lists it for commercial and residential use and for outdoor use only.

This model features electronic Hi/Lo ignition with flame sensing and electronic hot surface ignition. HPC’s Hi/Lo manual states that Bluetooth technology allows use with the supplied remote control or a compatible smartphone or tablet, and the drawing notes that Hi/Lo models have a 40% reduction in BTU on the low setting.

This 24VAC version requires a Class II 24VAC, 4-amp, 100W transformer, and HPC notes that lower-rated power supplies can affect performance. The same manual also states that electronic applications should use a GFCI-protected circuit and that the EI series must use permanent fixed piping for fuel supply.

This 33" x 15" version is rated at 150,000 BTU and configured for natural gas. HPC lists natural gas supply pressure at 3.5" to 7.0" W.C. for this EI series.
