eber does not sell conversion kits for any of their gas grills.Nor, do they recommend converting them, as a matter of safety. Each grill whether Natural Gas or Propane is tested and approved for that specific gas type.With Weber grills,as with many other brands, there's more to converting the grill from one gas type to another, than just changing the burner orifices. It also requires changing all the burners, because their venturi valves (air intake) are not adjustable.

Hope this helps you and thank you for choosing FixYa.

Unfortunately, Weber does not encourage or approve converting their grills from one gas type to another. Nor, do they sell any conversion kits or parts to do this. It's all in the interest of safety. Even if you attempted so do it, the parts alone would cost you almost as much, if not as much, as the restocking fee the seller wants to charge you. From what you have said, I suspect you bought the grill online, rather than from a brick & mortar retail store.

Sorry I didn't have better news for you.

Weber does not sell conversion kits due to liability reasons. Every part of the grill needs to be changed to convert. Cheaper to buy new grill, I have tried to piece together a parts list to convert, it is cheaper to buy new grill by the time you purchase all parts needed.

did you refit the connection to the gas bottle as there could be dirt under the taper or the "O" ring could be missing

Your zapper igniter is only to ignite one burner and that burner lights the other burner and so on. Follow the directions inside the left door and do it in the propper sequence and it should work as it suposed to.

After making sure your knobs are installed properly examine the full length of all burner tubes. You will be looking for areas of corrosion or damaged metal. Holes that are larger than they should be will cause too much LP expulsion resulting higher temperatures. Replacement parts, schematics, customer support and much more is available at the official Weber site. https://www.weber.com
