A "dual fuel" gas grill is required to convert a propane grill to natural gas. If you're going to, or have already, converted your grill, make sure that you have the Char-Broil natural gas conversion kit specified for your grill. If your grill is a Char-Broil Dual Fuel®-equipped gas grill model, the specified conversion kit model number is listed on the rating label of your grill. You can also look for a Dual Fuel Natural Gas Conversion Kit. You'll need to have your model number available.
If conversion to natural gas has resulted in lower than expected temperatures please call your local gas company for a service visit. Only the local gas company can determine if the proper pressure is being delivered to the grill. If your grill has more than 65,000 BTU’s, a 3/8” hose may not allow enough gas to flow. In this case a 1/2” hose is recommended.
