Firegear LP↔NG Fuel Conversion
Firegear sells conversion kits for most models in the Pro Series, SS Series, and Kalea Bay lineups. Conversion requires swapping the orifice, adjusting the regulator (propane side), and re-pressure-testing. Must be performed by a qualified installer — DIY voids the warranty.

What you need
- Conversion kit (model-specific)
- Licensed installer's tools and permits
Step by step
Order the model-specific conversion kit
Kits are specific to the burner model + the direction of conversion. Confirm the kit matches your unit's data plate.
Shut off fuel at the supply
No conversion work happens with fuel live.
Swap the orifice per the kit's diagram
Natural gas orifices are larger than propane orifices because natural gas has a lower energy density. Installer swaps the orifice sized to the new fuel.
Adjust the regulator (propane only)
Propane installations include a pressure regulator. Set to the spec in the kit's instructions.
Pressure-test, soap-test, commission
Re-do the pressure test and soap-test every joint. Commission the burner under the new fuel, confirm flame pattern is blue with yellow tips.
Common mistakes
- Running the old orifice on the new fuel. Not a conversion — just a misfire. Running propane on a natural-gas orifice produces a weak flame; running natural gas on a propane orifice over-fires and damages components.
Hands-on tips
- Document the conversion with photos — the data plate still shows the original fuel, and future service techs need to know it was converted.
