How to Convert a Propane Space Heater to a Natural Gas Space Heater


Space heaters provide supplemental heat to your home in place of the main heater. However, if you have a propane space heater, but a supply of natural gas, you’ll have to convert the heater to run on the natural gas, instead. The main difference between propane and natural gas is that natural gas moves at a lower pressure than propane, which means the orifices on the space heaters burner need to be larger to ignite the natural gas. If your space heater can be converted, the company that makes it will have conversion kits available.

Things You'll Need

  • Natural gas conversion kit
  • Wrench
  • Screwdriver
  • Unplug the space heater from the power source. Remove the propane regulator and gas line from the heater with the wrench.

  • Open the space heater with the screwdriver to get to the burners at the base of the heater.

  • Remove the propane orifices from the burner with the wrench. Tighten the natural gas orifices over the burner with the wrench.

  • Close the space heater and tighten the screws in place. Attach the natural gas line to the space heater and turn the heater on.
