Of course Weber barbecue grills can be converted to natural gas for cooking.
Here are the tips to covert.
1. As we saw, above the control panel on the side of the old Spirit models and the Genesis Silver and Gold and Platinum A, B and C models can be removed and lifted away from the control valves very easily. Once the control panel is out of the way we are looking at the gas line connected to the gas manifold connected to the control valves.
2.We are going to need to slide the burner off the valve so we can access the orifice. In order to slide the burner off the control valve we have two options. However, the condition of the barbecue will usually choose one of these options for us. If not you are lucky but the build up of grease and the breakdown of materials usually decides this for us.
3.We can go into the fire box with the cooking grates and flavorizer bars (Weber heat shield vaporizers) out of the way so the far left side bolts holding the pipe burners in place are accessible. If the bolts are not totally covered in cooking greases and years of sauces we can unscrew these bolts, lift the burner up from the far left corner and slide the burner away from the burner; the other option is to below the gas manifold on the far right side. Under the manifold are two flat steel support brackets holding the manifold pipe to the right side of the barbecue firebox. In their intelligent foresight Weber attached these brackets with thumb-screws easily unscrewed to slide the entire manifold assembly off the burners.
4.Once the burner slides off the control valve on the Weber manifold we will see the very tip of the valve looks like a bolt with a hex-head. If we look closer we will also see there is a tiny hole in this bolt-head. This is the gas orifice.
5.The gas orifice attaches to the valve and is inserted into the burner during normal barbecuing.The diameter of the hole drilled in this orifice in the tip of each control valve is what determines the BTU rating of each burner and of the grill as a whole.
Remember, if your Weber grill is designed to run on propane and you want to convert it over to natural gas then this article will show you what you need to do. Please keep in mind that although Weber used to routinely supply conversion kits they now state that performing the conversion is dangerous and will void your warranty.
