To convert orifices from LP to natural gas, what is the recommended action?

When converting orifices from LP (liquefied petroleum) gas to natural gas, it's essential to follow manufacturer recommendations to ensure safety and optimal equipment performance. The preferred and most reliable method is to replace the existing orifices with new ones designed specifically for natural gas use. This approach guarantees that the orifice size and specifications are accurate for the type of gas being used, which is crucial for achieving the correct air-to-fuel ratio and ensuring proper combustion.

Additionally, manufacturers often recommend providing a new data plate that corresponds with the converted system. This new data plate reflects the specifications necessary for safe operation with natural gas, including pressure settings and appliance configurations. By adhering to these guidelines, you ensure compliance with safety standards and avoid potential issues that could arise from improper adjustments or modifications.

Other methods, such as drilling or adjusting the existing orifices, can lead to improper gas flow and combustion issues, potentially creating dangerous situations. Therefore, replacing the orifices and updating pertinent information ensures that the system operates efficiently and safely.
