Grilling is a beloved pastime, and Napoleon grills have earned a reputation for quality and performance. Many grill owners start with a propane model for portability but later consider the convenience of natural gas. The question then arises: Can you convert your Napoleon propane grill to natural gas? The answer is generally yes, but it’s not as simple as just hooking it up. This comprehensive guide will walk you through everything you need to know about converting your Napoleon propane grill to natural gas, from assessing compatibility to understanding the conversion process and ensuring safety.
Understanding Propane and Natural Gas Differences
Before diving into the conversion process, it’s crucial to understand the fundamental differences between propane and natural gas. These differences significantly impact how grills are designed and how fuel is delivered.
Energy Content and Pressure
The primary difference lies in their energy content and pressure requirements. Propane, also known as LP (Liquefied Petroleum) gas, is a more energy-dense fuel than natural gas. This means that propane contains more British Thermal Units (BTUs) per cubic foot than natural gas. Propane delivers approximately 2,500 BTUs per cubic foot, while natural gas delivers around 1,000 BTUs per cubic foot.
The pressure at which these gases are delivered to your grill also varies. Propane is stored and delivered at a much higher pressure than natural gas. A standard propane tank typically delivers gas at a pressure of around 11 inches of water column (WC), while natural gas is delivered at a much lower pressure, typically around 4 inches of WC.
Burner Orifice Size and Regulator Requirements
Because propane is more energy-dense and delivered at higher pressure, propane grills have smaller burner orifices than natural gas grills. The orifice is the small opening in the burner that allows gas to flow through. A smaller orifice restricts the flow of propane, preventing the burners from receiving too much fuel.
Natural gas grills, on the other hand, have larger burner orifices to compensate for the lower energy content and pressure of natural gas. They also have different regulator requirements. A regulator controls the gas pressure flowing to the burners, ensuring consistent performance. Propane grills use a different type of regulator than natural gas grills to accommodate the different pressure requirements.
Assessing Your Napoleon Grill’s Conversion Potential
Not all Napoleon grills are created equal, and not all are easily convertible. The first step is to determine if your specific model is designed for conversion or if a conversion kit is available.
Checking Your Grill’s Model Number
Locate your grill’s model number. This is usually found on a sticker or plate on the grill’s body, often on the back or inside the cabinet. Once you have the model number, visit Napoleon’s website or contact their customer service department. Napoleon’s website often has a support section where you can enter your model number and find information about conversion kits and compatibility.
Conversion Kit Availability
Napoleon typically offers conversion kits for many of their grill models. These kits usually include the necessary components to safely and effectively convert your grill from propane to natural gas. If a conversion kit is available for your model, it’s a strong indication that conversion is possible and supported by the manufacturer.
Considering Grill Age and Condition
The age and condition of your grill can also play a role in the feasibility of conversion. If your grill is very old or heavily corroded, it may not be worth the effort or expense to convert it. Older grills may have components that are difficult to replace or that are no longer compatible with conversion kits.
