Converting a grill from propane to natural gas can seem like a daunting task, but with the right knowledge and preparation, it’s entirely possible. Many Dyna-Glo grill owners wonder if they can make this conversion to take advantage of natural gas’s convenience and potentially lower cost. This comprehensive guide will walk you through the considerations, the process, and the potential pitfalls of converting your Dyna-Glo grill to natural gas.
Understanding the Differences: Propane vs. Natural Gas
Before diving into the conversion process, it’s crucial to understand the fundamental differences between propane and natural gas. These fuels have distinct properties that directly impact how a grill operates. Propane, also known as Liquefied Petroleum Gas (LPG), is stored under pressure as a liquid. When released, it vaporizes into a gas. Natural gas, primarily methane, is delivered through pipelines at a much lower pressure.
The most significant difference lies in their energy content. Propane contains approximately 2,500 BTU (British Thermal Units) per cubic foot, while natural gas has only around 1,000 BTU per cubic foot. This difference in energy density means that natural gas grills require larger orifices (the small openings that release gas into the burner) to deliver the same amount of heat as a propane grill.
Another critical factor is pressure. Propane typically operates at a higher pressure than natural gas. Propane grills use a regulator to control the flow of gas from the tank at around 11 inches of water column (WC). Natural gas, on the other hand, typically operates at a pressure of around 4 inches WC. These pressure differences necessitate changes to the grill’s regulator and orifices during conversion.
Is Your Dyna-Glo Grill Convertible?
Not all Dyna-Glo grills are created equal when it comes to conversion. Some models are designed to be easily convertible, while others might require significant modifications or might not be suitable for conversion at all. It is essential to check your grill’s model number and consult the owner’s manual to determine its convertibility.
Look for any mention of natural gas conversion kits or instructions in the manual. If the manual explicitly states that the grill is convertible, it’s a good sign. However, if the manual makes no mention of natural gas or advises against conversion, it’s best to proceed with caution or consult a professional.
Another important factor is the availability of a conversion kit. If Dyna-Glo or a third-party manufacturer offers a conversion kit specifically designed for your grill model, it simplifies the process significantly. A conversion kit typically includes the necessary orifices, regulator, and instructions for a safe and effective conversion.
If no conversion kit is available, converting your Dyna-Glo grill to natural gas becomes much more challenging and potentially dangerous. It would involve sourcing individual components with the correct specifications, which can be difficult and requires a thorough understanding of gas appliance mechanics.
Required Components for Natural Gas Conversion
If you’ve determined that your Dyna-Glo grill is convertible and a conversion kit is available (or you’re confident in sourcing the individual components), you’ll need the following:
- Natural Gas Regulator: This regulator is designed to reduce the natural gas pressure from your home’s supply to the pressure required by the grill (typically 4 inches WC). A correctly sized regulator is crucial for safe and efficient operation.
- Natural Gas Orifices: These are the small brass fittings that control the flow of gas to the burners. Natural gas orifices have a larger opening than propane orifices to compensate for the lower BTU content of natural gas. Using the correct orifice size is critical for achieving the proper flame and heat output.
- Conversion Instructions: A detailed instruction manual is essential for a successful conversion. The instructions should provide step-by-step guidance on how to replace the regulator and orifices.
- Leak Detection Solution: You’ll need a leak detection solution (soap and water mixture) to test all connections after the conversion is complete. Leak testing is a mandatory safety measure.
- Tools: You’ll need basic tools like a screwdriver, wrench, and possibly a drill with drill bits (depending on the kit and grill model). Ensure you have the right tools before starting the process.
- Flexible Gas Line: A flexible gas line is used to connect the grill to your natural gas supply line. Make sure it is rated for outdoor use and is the appropriate length.
- Pipe Thread Sealant: Used to seal threaded connections and prevent leaks. Use a gas-rated sealant.
The Conversion Process: Step-by-Step Guide
While specific steps may vary depending on your Dyna-Glo grill model and the conversion kit, the general process involves the following:
- Safety First: Before starting any work, disconnect the propane tank (if applicable) and ensure the gas supply is turned off. Work in a well-ventilated area and wear appropriate safety gear, such as gloves and eye protection. Never work on a gas appliance near open flames or sources of ignition.
- Remove Propane Regulator: Disconnect the propane regulator from the grill. This usually involves unscrewing it from the gas inlet. Be careful not to damage the gas inlet threads.
- Install Natural Gas Regulator: Attach the natural gas regulator to the grill’s gas inlet. Use pipe thread sealant on the threads to ensure a gas-tight seal. Tighten the regulator securely. Do not overtighten, as this could damage the threads.
- Replace Propane Orifices with Natural Gas Orifices: Locate the propane orifices in the grill’s burner assembly. These are usually small brass fittings screwed into the burner tubes. Remove the propane orifices and replace them with the natural gas orifices provided in the conversion kit. Ensure the orifices are securely tightened but not overtightened.
- Connect the Grill to the Natural Gas Supply: Connect the flexible gas line to the natural gas regulator on the grill and to the natural gas supply line on your property. Use pipe thread sealant on all threaded connections. Ensure the gas line is properly sized and rated for outdoor use.
- Leak Test: Once all connections are made, turn on the natural gas supply. Use a leak detection solution (soap and water mixture) to check all connections for leaks. Apply the solution to the connections and look for bubbles. If you find any leaks, turn off the gas supply immediately and tighten the connections. Repeat the leak test until no leaks are found. Leak testing is crucial for safety.
- Adjust Burner Flames: After the conversion is complete and you’ve confirmed there are no leaks, light the grill and observe the burner flames. The flames should be blue with a slight yellow tip. If the flames are excessively yellow, orange, or sooty, it indicates a problem with the gas mixture or airflow. Adjust the air shutters on the burners to achieve the proper flame characteristics.
Potential Problems and Troubleshooting
Even with careful preparation, you might encounter problems during or after the conversion. Here are some common issues and their solutions:
- Gas Leaks: This is the most serious issue. If you detect a gas leak, turn off the gas supply immediately and tighten the connections. If the leak persists, call a qualified gas technician. Never ignore a gas leak.
- Low Flame Height: If the flames are too low, it could be due to an undersized regulator, incorrect orifices, or low gas pressure from your supply line. Check the regulator specifications and ensure the orifices are the correct size. Contact your gas company to check the supply pressure.
- Yellow or Orange Flames: This usually indicates incomplete combustion, which can be caused by insufficient airflow. Adjust the air shutters on the burners to increase airflow. Also, ensure the burners are clean and free of debris.
- Uneven Heating: Uneven heating can be caused by clogged burner ports or incorrect orifice size. Clean the burner ports with a wire brush or drill bit. Check the orifice size for each burner and ensure they are properly matched.
- Difficulty Lighting: Difficulty lighting can be caused by a weak igniter, dirty burner ports, or low gas pressure. Clean the igniter and burner ports. Check the gas pressure and ensure the regulator is functioning correctly.
