When it comes to converting a propane grill to natural gas, there are several key components that need to be changed. One of the main differences between propane and natural gas is the pressure at which they are delivered. Propane is delivered at a higher pressure than natural gas, so the burner tubes need to be specifically designed for the type of gas being used.
To convert a propane grill to natural gas, you will need to purchase different burner tubes that are specifically designed for natural gas. These burner tubes are typically larger in diameter than propane burner tubes to accommodate the lower pressure of natural gas. The size and shape of the burner holes are also different, as natural gas requires a different air-to-gas ratio for proper combustion.
In addition to changing the burner tubes, you will also need to change every small orifice fitting in the grill. Orifice fittings are responsible for controlling the flow of gas to the burners, and they are sized differently for propane and natural gas. The orifice fittings in a propane grill are designed to allow for the higher pressure of propane, so they need to be replaced with fittings that are specifically designed for the lower pressure of natural gas.
Replacing the orifice fittings can be a tedious task, as they are typically located in the valve manifold of the grill. This means that you will need to replace the entire valve manifold to convert the grill from propane to natural gas. The valve manifold is responsible for controlling the flow of gas to the burners, and it includes all of the necessary fittings and connections for the gas supply.
Once you have replaced the burner tubes and the valve manifold, you will also need to purchase a longer hose to connect the grill to the natural gas supply. Propane grills typically come with a shorter hose that is designed to connect to a propane tank, so a longer hose will be needed to reach the natural gas supply. It's important to ensure that the hose you purchase is designed for natural gas and is properly rated for the pressure and volume of gas being used.
Converting a propane grill to natural gas requires careful attention to detail and the use of specific components designed for the type of gas being used. It's important to follow the manufacturer's instructions and guidelines for converting your specific grill model, as different grills may have different requirements. If you're unsure about the conversion process, it's always best to consult a professional or contact the grill manufacturer for assistance.
Burners for propane and natural gas are not the same. Converting a propane grill to natural gas requires the purchase of different burner tubes, changing every small orifice fitting by replacing the entire valve manifold, and purchasing a longer hose to connect to the natural gas supply. It's a process that requires attention to detail and the use of components specifically designed for the type of gas being used.
