Natural Gas is piped gas and is heavier than air. If you already have natural gas in your home, but do not have it plumbed to your gas grill, a certified gas technician should be able to run the lines for a gas BBQ grill. Your plumber will use the BTU output to determine the proper line diameter that your grill requires. Feeding a bbq grill too little gas can lead to operational issues. If you already won a natural gas BBQ grill and need grill parts, we stock those as well.
