The Rheem FP-38 LP Conversion Kit is designed for conversion of Rheem Air 90 Series Gas Furnaces from natural gas to propane operation. This conversion kit allows homeowners to take advantage of the cost savings and availability benefits of using propane as a fuel source, even if their furnace was originally designed for natural gas.
The FP-38 LP Conversion Kit comes with several key components required for the safe and efficient operation of the furnace on propane. These components include a new propane gas valve assembly, a new igniter, and a set of orifices for the burners to ensure proper fuel mixture and combustion. The conversion kit also includes a conversion manual with clear instructions for the installation process.
The propane gas valve assembly is a critical component of the conversion kit. It is designed to work seamlessly with the Rheem Air 90 Series Gas Furnace's existing control system and features a built-in safety system to prevent gas flow when the furnace is not in use. The igniter, on the other hand, is designed specifically for use with propane and ensures reliable ignition of the furnace's burners.
The burner orifices are an essential part of the conversion process, as they control the flow of fuel to the burners. The FP-38 LP Conversion Kit includes the correct orifices for the Air 90 Series Gas Furnace when it is being operated on propane. These orifices are specifically designed to ensure proper fuel mixture and efficient combustion, ensuring that the furnace continues to operate at peak performance.
Overall, the Rheem FP-38 LP Conversion Kit is an excellent solution for homeowners looking to convert their Rheem Air 90 Series Gas Furnace from natural gas to propane operation. With its high-quality components, clear installation instructions, and reliable performance, this conversion kit offers a cost-effective and convenient way to take advantage of the benefits of using propane as a fuel source.
The Rheem FP-38 LP Conversion Kit is designed to allow the conversion of an existing Rheem Air 90 Natural Gas Furnace into a Low-Pressure (LP) Gas furnace. Here are some pros and cons of buying this conversion kit:
Pros:1. Cost-effective: Converting an existing furnace to LP Gas instead of buying a new one can save significant costs, especially for those who are satisfied with their current furnace's performance but want to switch to LP Gas due to cost or availability reasons.
2. Reduces greenhouse gas emissions: LP Gas produces fewer greenhouse gas emissions compared to natural gas, making it a more eco-friendly option for those concerned with their carbon footprint.
3. Flexibility: LP Gas is often more available in rural areas where natural gas may not be readily accessible, making the conversion kit an attractive option for those living in such locations.
Cons:1. Installation complexities: The conversion process involves intricate steps, such as removing and replacing parts, and ensuring proper gas pressure and venting. It is recommended that the conversion be done by a certified HVAC professional to avoid potential hazards and ensure optimal performance.
2. Potential compatibility issues: It is essential to ensure that the existing furnace is compatible with the conversion kit. In some cases, the furnace's age, design, or other factors may impact its ability to be converted successfully.
3. Cost of conversion: Although the conversion kit itself is cost-effective, the overall cost of the conversion process, including labor, parts, and inspection fees, can add up significantly.
In conclusion, the Rheem FP-38 LP Conversion Kit offers a cost-effective and eco-friendly solution for those looking to convert their existing Rheem Air 90 Natural Gas Furnace to LP Gas. However, the conversion process comes with its complexities, compatibility considerations, and potential costs. It is recommended that individuals weigh the pros and cons carefully and consult with a certified HVAC professional before deciding on the conversion.
If you have determined that the conversion is the best option for your situation, purchasing the Rheem FP-38 LP Conversion Kit can save you money in the long run while also reducing your carbon footprint. However, if the complexities and potential costs outweigh the benefits for your specific case, it may be worth considering alternative options, such as purchasing a new LP Gas furnace or exploring other energy sources. Ultimately, the decision depends on your unique circumstances and priorities.
