Natural Gas to Propane Conversion Kits – MDTECH Technical Solutions

MDTECH Technical Services specializes in the professional installation and validation of Natural Gas (NG) to Liquid Propane (LP) conversion kits for gas appliances, particularly ranges, ovens, and cooktops. We serve the Greater Los Angeles and Orange County, California areas.

Converting an appliance from natural gas to propane is a critical technical procedure required because LP gas is delivered at a higher pressure and contains more than twice the energy per cubic foot than NG. This conversion is mandatory for both appliance performance and user safety.

Licensed Conversion and Installation Service

As C-20 licensed mechanical contractors, MDTECH provides certified gas fitting services for these complex conversions, ensuring compliance with all local codes and manufacturer specifications.

1. Orifice Replacement (Precise Fuel Delivery)

The most crucial step in any conversion is replacing the appliance’s orifices (jets).

• NG Orifices have a larger opening to accommodate the lower pressure and lower energy density of natural gas.

• LP Conversion Kits contain new, smaller orifices that precisely restrict the flow of the higher-pressure, higher-energy propane gas.

• MDTECH Service: We install the correct, manufacturer-specific LP orifices for every burner, the oven burner, and the broil burner, ensuring proper BTU output and preventing excessive flames or incomplete combustion (sooting).

2. Regulator Adjustment and Calibration

The appliance’s main gas pressure regulator must be reconfigured to handle the higher input pressure of propane (typically 10 to 11 inches Water Column).

• MDTECH Service: We utilize the specific components provided in the conversion kit (such as a spring or a convertible pin) to modify the pressure regulator. We then use a manometer to accurately test and set the final burner manifold pressure to the LP specification, ensuring stable, blue flames.

3. Air Shutter and Flame Adjustment

Propane and Natural Gas require different amounts of air for clean combustion.

• MDTECH Service: After installing the new regulator and orifices, we adjust the air shutters on the burner venturis until the flames exhibit the correct appearance: stable, clean, and blue with sharply defined inner cones. This step prevents the creation of excessive soot or potentially dangerous carbon monoxide (CO).

4. Mandatory Safety Verification

Following all technical modifications, MDTECH performs mandatory safety testing.

• Leak Testing: We use certified leak detection fluid or electronic sensors on all connections to confirm zero leaks within the gas piping and appliance assembly.

• Labeling: We affix the required safety sticker to the appliance, indicating that the unit has been successfully and safely converted to use LP gas.
