Firegear 36" x 12" Linear H-Burner Fire Pit Insert, Stainless Steel

At 100,000 BTU — 29.30 kW for the metrically inclined — the Firegear LOF-3612HTPSI-P delivers a serious column of flame across a 33" x 10" stainless steel H-shaped linear burner. That's the kind of output that commands attention in a well-designed outdoor living space, not the kind that politely flickers in the background.

The pan dimensions are 36" x 12" (inside dimension), which keeps the geometry clean and predictable for fire feature builders and designers working with stone, concrete, or metal surrounds. The burner itself sits at 8" in height, and the full assembly is constructed from stainless steel — chosen for its resistance to the thermal cycling and weather exposure that outdoor fire applications demand.

Ignition is handled by Firegear's TPSI system: a Thermocouple Piloted Safety Ignition with a battery-powered spark igniter. In practical terms, this means no open-flame lighting, no external power connection required, and a thermocouple that automatically cuts gas flow if the flame is ever extinguished unexpectedly. It's the kind of safety feature that becomes invisible when everything's working and invaluable when something isn't.

This model is factory-configured for Liquid Propane and uses the OAS-LP35 propane orifice. It is not field-convertible to natural gas — if your installation calls for NG, the LOF-3612HTPSI-N is the correct variant. Fuel type isn't a setting here; it's baked into the hardware, so ordering the right version from the start matters.

Installation requires careful attention to clearances: 36" from combustibles on the sides and back, 18" on the bottom, and either 96" or 120" overhead depending on your configuration. Cross ventilation of at least 18 square inches per side is required — a detail worth coordinating with your contractor or fire feature installer before the surround goes in. BTU output may vary slightly depending on flex line size and gas pipe sizing, so proper gas system design is part of getting the full performance out of this burner.

Whether the application is a custom concrete trough, a sleek rectangular fire table, or an architectural built-in, the LOF-3612HTPSI-P is a well-specified, professionally-oriented burner system with the output and ignition quality to match.
