Run Your Square Gas Fire Pit Insert from a Wall Switch

This square gas fire pit insert lights with hot surface ignition, so nobody crouches at the pit with a lighter or works a key valve. It is fully assembled and CSA certified for outdoor use, in 18 gauge #304 stainless steel that HPC lists as commercial grade. It comes in five sizes, 18 to 42 inches, on natural gas or propane.

HPC Fire square gas fire pit insert with Penta burner, flat stainless pan and electronic ignition control box

Key Features

  • Flame sensing shutoff: a thermocouple shuts the gas off if the flame goes out, so no gas keeps flowing.
  • Control options: a wall switch is required for safety shutoff, plus an optional remote, timer or smart home system.
  • Up to 400,000 BTU: the 42 inch Penta is rated 400,000, and the 18 inch starts at 65,000.
  • Flat recessed pan: sets into your enclosure and costs less than the square bowl version.

The Full Picture

Electronic ignition, the top of HPC's three ignition tiers, lets this square gas fire pit insert start from a wall switch with nothing to light by hand. HPC says electronic ignition is required for most commercial applications. The flat pan recesses into an enclosure, so it suits a square fire pit planned into a new build or a renovation of your property.

How the Electronic Ignition Fire Pit Insert Works

Switching on starts a sequence that ends with the burner lit.

  • Hot surface igniter: glows when you switch on and lights the pilot.
  • Thermocouple: the pilot warms it, and once it is hot the main valve opens and the burner lights.
  • Automatic restart: if the pilot blows out, the system shuts down and restarts on its own.
  • Overheat shutoff: the gas valve closes if the valve box temperature exceeds 190°F.
  • Penta burner: HPC's patented five lobe design gives a taller center flame.
  • Torpedo burner: adds nozzles to the burner, and HPC calls it commercial grade.

Depth tolerance Depth below the pan is plus or minus 1/2 in. Shipping figures are for Standard burner models only.
Location Above grade, with good drainage and access for installation and maintenance. Keep granite, marble and other dense stone away from heat and flame, since it can crack.
Deck installation On a wood or composite deck, the Deck Insulation Kit (FPI-DECK39SQ or FPI-DECK20SQ) and locally bought paver stones are required.
Pan position Recess the pan at least 2 inches below the top of the enclosure so the flame is not blown out.
Enclosure build Noncombustible materials. The pan, not the control or valve box, supports the weight. The void space around the valve box stays empty.
Gas shutoff The supply line needs a gas shutoff on the outside of the enclosure.
Venting Enclosures up to 200,000 BTU: at least 2 vents, 18 square inches each, on opposing sides (36 square inches of free area, for example 3 x 6 in or larger). Above 200,000 BTU: at least 4 vents, 18 square inches each, on opposing sides.
Clearance to sides Up to 200,000 BTU: 36 in to structures or combustibles, 12 in to noncombustible. 201,000 to 400,000 BTU: 48 in, or 24 in to noncombustible.
Clearance above and below 84 in overhead for models up to 200,000 BTU. 2 in under the valve box for drainage.
Media Designed for approved media over the burner. Lava rock only deep enough to cover the burner, or decorative glass 1/4 to 1/2 inch over it. Never gravel, pebbles or river rock. Keep media off the blowout box vents. A Penta burner's flame is smaller with no media.
Warranty Stainless steel burner: lifetime. Electronics and gas valve: 3 years residential, 1 year commercial. Pilot assembly: 2 years residential, 1 year commercial. Stainless steel pan and valve box: 5 years residential, 1 year commercial.

Frequently Asked Questions
How is this different from the Hi/Lo version?
The Hi/Lo version adds Bluetooth control through HPC's Fire One app, adjustable flame height and a remote. This insert is On/Off, with its remote sold separately.
Can I change the flame height on this insert?
A trimmer valve under the insert reduces manifold pressure to lower the flame height and BTU rating.
Can I install it myself?
HPC's manual says a qualified installer, service agency or the gas supplier must install and service it.

Plan on a wall switch, 120 VAC power and permanent gas piping at the pit. Talk through your enclosure and gas supply with a Resorts Depot product expert.
