Understanding Natural Gas and Propane
Natural gas is a fossil fuel, mainly composed of methane. It’s commonly used in heating systems and appliances. Propane, on the other hand, is a byproduct of natural gas processing and petroleum refining. It’s stored as a liquid and vaporizes when released.
Key Differences
- Energy Content: Propane has a higher energy content than natural gas. One gallon of propane contains about 91,500 BTUs, whereas one therm of natural gas offers about 100,000 BTUs. This means propane is more efficient for heating and appliances.
- Cost: Prices for both fuels fluctuate. Often, propane can be cheaper than natural gas, depending on market conditions. Determining current prices helps in deciding which fuel offers better savings.
- Storage: Natural gas is delivered through pipelines. Propane is stored in tanks and can be delivered in liquid form. Ensure you consider your property’s infrastructure for storage options.
Environmental Impact
Natural gas burns cleaner than coal and oil, producing fewer emissions. However, propane is also considered a clean fuel, producing only water vapor and carbon dioxide when combusted. Both options serve as cleaner alternatives to traditional heating fuels, supporting efforts to reduce environmental footprints.
Safety Considerations
Both gases are flammable and require safe handling. Natural gas is lighter than air, dispersing easily, while propane is heavier, pooling in low areas. Proper ventilation during usage is crucial for both. Always check for leaks and adhere to safety guidelines to ensure a hazard-free environment.
Understanding these differences equips you to make informed decisions about switching from natural gas to propane for your heating needs.
Benefits of Converting to Propane
Switching from natural gas to propane offers several advantages that can improve your home’s heating experience. Here are key benefits to consider:
Efficiency and Cost Savings
Propane boasts a higher energy content than natural gas. When converted, your home can achieve better heating efficiency. For example, propane has an energy content of approximately 91,500 BTUs per gallon, compared to natural gas, which averages 1,000 BTUs per cubic foot. This means you need less propane to generate the same amount of heat.
Additionally, propane prices often fluctuate less than natural gas prices. Over time, you may notice reduced monthly heating bills due to stable propane costs. Make sure to compare current rates in your area for accurate cost assessments.
Environmental Impact
Propane burns cleaner than natural gas, producing fewer greenhouse gases and pollutants. As a clean-burning fuel, propane emits 39% less carbon dioxide than coal and significantly lower emissions than oil. By converting your furnace to propane, you’re choosing a more environmentally friendly option.
Moreover, propane does not produce soot or ash, helping to maintain a cleaner living environment. Transitioning to propane can positively impact air quality both indoors and outdoors. If you prioritize eco-friendly home heating, propane is an excellent choice.
Preparing for the Conversion
Before starting the conversion of your natural gas furnace to propane, gather all necessary tools and materials. Being well-prepared ensures a smoother process and enhances safety.
Tools and Materials Needed
- Propane Conversion Kit: Includes essential components designed for your specific furnace model.
- Wrench Set: Use for loosening and tightening connections.
- Screwdrivers: Both flathead and Phillips types come in handy.
- Gas Leak Detector: Detects leaks after the conversion for safety.
- Adjustable Pliers: Useful for gripping and twisting.
- Tape Measure: Ensures proper fitting of new components.
- Safety Glasses: Protect your eyes while working.
- Work Gloves: Prevents injuries when handling tools and components.
Ensure all materials match your furnace’s specifications for a successful conversion.
- Shut Off the Gas Supply: Locate and turn off the natural gas valve before starting.
- Ventilate the Area: Open windows and doors to allow fresh air circulation, reducing the risk of gas accumulation.
- Use Protective Gear: Always wear safety glasses and gloves to prevent injuries.
- Check for Leaks: After conversion, use the gas leak detector and a soap solution to identify any leaks at connections.
- Have a Fire Extinguisher Handy: Keep a suitable extinguisher nearby in case of emergencies.
Following these precautions helps ensure a safe and effective conversion process.
Step-by-Step Conversion Process
Converting a natural gas furnace to propane involves a few critical steps. Follow these instructions carefully to ensure successful conversion and safe operation.
Adjusting the Burner Assembly
- Access the Burner Assembly: Remove the front cover of the furnace. This typically involves unscrewing a few screws.
- Inspect the Burner: Check the burner assembly for any dirt or debris. Clean it if necessary to ensure proper airflow.
- Adjust the Air Shutter: Locate the air shutter on the burner assembly. Adjust it to increase or decrease the air mixture. Propane requires less air than natural gas, so close the shutter slightly to improve combustion efficiency.
Changing the Orifices
- Locate Orifices: Find the gas orifices in the burner assembly. These control the gas flow to the burners.
- Remove the Existing Orifices: Use the appropriate wrench to unscrew the current orifices. Keep them for reference during the installation.
- Install Propane Orifices: Replace the old orifices with those included in the propane conversion kit. Ensure they match the specifications required for propane.
- Turn Off the Gas Supply: Before making any adjustments, cut off the gas supply to the furnace.
- Adjust the Gas Valve: Locate the gas valve, which typically has a conversion setting. Adjust the valve according to the guidelines in the conversion kit.
- Reconnect the Gas Supply: Once all components are modified, reconnect the gas supply. Check for any leaks using soapy water on the connections. Bubbles indicate a leak, so ensure tight seals.
By following these steps, you can successfully convert your natural gas furnace to propane, enhancing your home’s heating efficiency.
Testing and Finalizing the Installation
After the conversion process, it’s crucial to test and finalize the installation to ensure safe and optimal operation of your propane furnace.
Conducting a Leak Test
- Use Soapy Water: Mix equal parts of water and liquid soap in a spray bottle. Spray the solution on all gas connections and fittings.
- Observe for Bubbles: If bubbles form, that indicates a gas leak. Tighten the connection and retest until no bubbles appear.
- Seal Any Leaks: Use thread sealant or tape designed for gas connections if necessary.
Checking Gas Pressure
- Attach a Manometer: Connect a manometer to the gas manifold on your furnace.
- Start the Furnace: Ignite the furnace to observe the gas pressure reading. It should match the specifications outlined in your propane conversion kit instructions.
- Adjust if Needed: If the pressure doesn’t align, adjust the regulator to increase or decrease as required.
Testing the Ignition System
- Turn on the Furnace: Switch on the furnace and allow it to run while watching the ignition system.
- Observe Flame Quality: The flame should be blue and steady with minimal yellow tips, indicating proper combustion.
- Adjust the Burner: If the flame appears to be uneven or yellow, adjust the burner or orifices according to the conversion kit’s instructions.
Safety Checks
- Carbon Monoxide Detector: Ensure that you have a working carbon monoxide detector near the furnace and test it to confirm functionality.
- Ventilation: Double-check that the furnace venting system is clear and functioning properly to prevent any harmful gas buildup.
- Gas Supply: Ensure the propane supply is turned on and that you can reach the shutoff valve quickly in case of an emergency.
- Secure Access Panels: Make sure that all access panels are reattached properly after testing.
- Document Changes: Record any adjustments made during the conversion for future reference, including gas pressures and any part replacements.
- Professional Inspection: For added peace of mind, consider scheduling a professional inspection after the initial setup to ensure everything meets local codes and safety standards.
Following these steps guarantees a smooth and safe transition to your new propane furnace, optimizing its performance and enhancing your home’s heating efficiency.
