FAQ: Natural Gas Grills
Q: Are natural gas grills better than propane grills?
A: Natural gas grills offer the convenience of never running out of fuel and are generally cheaper to operate (about 1/3 the cost per BTU). However, propane grills are more portable and produce slightly higher heat. The best choice depends on your specific needs and setup.
Q: Can I convert a propane grill to natural gas?
A: Some grills are designed to be convertible with manufacturer-approved conversion kits. Never attempt to convert a grill that isn’t specifically designed for it, as this can be dangerous and will void your warranty. Conversion typically costs $50-150 for the kit plus professional installation.
Q: How long do natural gas grills last?
A: With proper maintenance, a high-quality natural gas grill can last 10-15 years or more. Premium brands with 304 stainless steel construction can last 20+ years. Key factors affecting lifespan include build quality, maintenance frequency, and weather exposure.
Q: Do natural gas grills need electricity?
A: Most natural gas grills don’t require electricity for basic operation, using piezo or battery-powered ignition. However, some features like rotisserie motors, LED lights, or smart connectivity will need electrical power.
Q: Are natural gas grills safe?
A: Yes, when properly installed by a licensed professional and maintained according to manufacturer guidelines, natural gas grills are very safe. They eliminate risks associated with propane tank storage and transportation.
Q: How often should I clean my natural gas grill?
A: Clean the grates after each use while still warm. Perform a deep clean monthly during grilling season, including burners, flavorizer bars, and grease traps. Do a comprehensive cleaning at the start and end of each season.
Q: Can I use a natural gas grill indoors?
A: No, natural gas grills are designed for outdoor use only. Using them indoors poses serious carbon monoxide poisoning and fire risks. Even covered patios require proper ventilation.
Q: What’s the typical cost to run a natural gas line for a grill?
A: Installation costs typically range from $200-500 for standard installations within 20 feet of existing gas lines. Complex installations requiring longer runs or permits can cost $500-1,000+.
Q: Do natural gas grills heat up as quickly as propane?
A: Natural gas grills typically take 10-15 minutes to preheat, similar to propane. While natural gas has lower BTU content per cubic foot, properly designed burners compensate for this difference.
Q: Can I move my natural gas grill once it’s installed?
A: Natural gas grills can be moved within the length of their gas hose (typically 10-12 feet) if using a quick-connect fitting. For greater distances, you’ll need to install a new gas connection point.
Q: What size gas line do I need for a natural gas grill?
A: Most residential grills require a 1/2″ gas line for runs under 20 feet. Longer distances or high-BTU grills may need 3/4″ pipe. Your installer will calculate the correct size based on BTU load and distance.
Q: How do I winterize my natural gas grill?
A: Clean thoroughly, shut off the gas valve, disconnect if using quick-connect, apply stainless steel protectant, and cover with a weatherproof cover. In extreme climates, consider storing removable components indoors.
