Converting a natural gas patio heater to propane can be a cost-effective and practical solution, especially if you’re looking to use your heater in an area without access to natural gas. This comprehensive guide will walk you through the step-by-step process of converting your natural gas patio heater to propane, ensuring a safe and efficient transition.
Preparing for the Conversion
Before you begin the conversion process, it’s essential to gather the necessary tools and materials. You’ll need a drill with a 5/16 nut driver or bit, a set of propane orifices, and a pressure regulator suitable for propane. Additionally, make sure to have a wrench or pliers on hand to loosen and tighten the connections.
Removing the Access Panel
The first step in the conversion process is to remove the access panel of your patio heater. This will give you access to the burner assembly and the orifices. Use the drill with a 5/16 nut driver or bit to remove the screws holding the access panel in place. Typically, there will be two screws in the front and two in the back.
Locating the Orifices
The orifices are the small openings that control the flow of gas to the burner. In most patio heater models, the orifices are located in the burner assembly. Carefully inspect the burner assembly to identify the orifices, which may be arranged in a specific pattern or configuration.
Changing the Orifices
To convert from natural gas to propane, you’ll need to replace the natural gas orifices with propane orifices. Locate the tube that holds the orifices and loosen it to remove the orifices. Be sure to note the orientation and placement of the orifices, as you’ll need to reinstall the propane orifices in the same manner.
The size of the propane orifice will depend on the BTU rating of your patio heater. As a general guideline, a 50,000 BTU heater would require a #47 drill bit for the propane orifice. Consult the manufacturer’s instructions or a gas appliance conversion chart to determine the correct orifice size for your specific model.
Adjusting the Pressure Regulator
Propane burns at a higher pressure than natural gas, so you may need to adjust the pressure regulator to ensure the heater operates safely and efficiently. Check the manufacturer’s instructions for the recommended pressure setting for propane. This step is crucial, as an improper pressure setting can lead to safety issues or poor performance.
Testing the Heater
Once you’ve made the necessary adjustments, it’s time to test the heater. Turn on the gas supply and ignite the burner. Observe the flame pattern and color, ensuring that it’s consistent and stable. Check for any gas leaks around the connections, and make any necessary adjustments to the orifices or pressure regulator.
Technical Specifications
- Orifice size: The size of the orifice will depend on the BTU rating of the heater. For example, a 50,000 BTU heater would require a #47 drill bit for a propane orifice.
- Pressure regulator: The pressure regulator may need to be adjusted to ensure the heater operates safely and efficiently with propane. Check the manufacturer’s instructions for the recommended pressure setting.
DIY Conversion Considerations
Converting a natural gas patio heater to propane can be a DIY project, but it’s essential to follow the manufacturer’s instructions and take appropriate safety precautions. Make sure to turn off the gas supply and allow the heater to cool down before making any adjustments. If you’re not comfortable with the conversion process, consider hiring a professional to ensure the job is done safely and correctly.
Conclusion
By following this comprehensive guide, you can successfully convert your natural gas patio heater to propane, allowing you to enjoy the warmth and ambiance of your outdoor space with greater flexibility. Remember to always prioritize safety and consult the manufacturer’s instructions throughout the conversion process.
