Answer:
A new burner orifices: These are small openings in the burner assembly that allow the correct amount of gas to flow into the furnace. The orifices in the kit will be different than the orifices in the natural gas furnace, as they are designed to work with the different pressure and flow rate of propane.
A new gas valve: The gas valve controls the flow of gas into the furnace. The gas valve in the conversion kit will be designed to work with propane, as it will have different pressure and flow characteristics than the natural gas valve.
A new regulator: This component reduces the pressure of the gas as it enters the furnace. The regulator in the conversion kit will be designed to work with propane, as it will have different pressure and flow characteristics than the natural gas regulator.
Instructions and documentation: The conversion kit should include detailed instructions and documentation on how to safely and correctly convert the furnace. This documentation should include all the necessary information such as safety precautions, tools needed, and step-by-step instructions.
In addition to the components mentioned above, the technician should also expect to find any additional parts or components that are required to complete the conversion process safely and efficiently. This can include, but not limited to, the venting system, any electrical components or wiring, and any additional hardware needed to complete the conversion.
It's important to note that the conversion process requires expert knowledge, skills and experience, and should only be carried out by a qualified and experienced technician. Additionally, the technician should follow the manufacturer's instructions and comply with local codes, regulations and safety standards
