On a natural-gas-to-LPG furnace conversion, who is correct regarding the necessary component changes?

In the scenario of converting a natural gas furnace to operate on liquefied petroleum gas (LPG), it is essential to understand that the pressures and fuel characteristics of the two gas types differ significantly. Technicians involved in this conversion need to ensure that specific components are adjusted or replaced to facilitate the safe and effective operation of the furnace with LPG.

Technician B is correct because this technician acknowledges the necessity of replacing specific burners designed for natural gas with those that are compatible with LPG. This is crucial because LPG burns differently than natural gas, requiring a change in the combustion components to ensure proper air-fuel mixture, combustion efficiency, and safety.

In contrast, components not related to the combustion process, such as the heat exchanger, might not require changes, as they can function effectively regardless of the fuel type. Understanding these nuances allows technicians to make informed decisions about which components must be modified or replaced to ensure the furnace operates safely and efficiently after the conversion.
