Where do I find a NG to lp conversion for a weber e-310

Try Calgary BBQ center they are on line

Ronni, unfortunately none of the Weber grills are approved for conversion from one type of gas to another. Each grill is tested and approved for it's specific gas type. Based on that, converting it, places all the liability on you, if something should go wrong. In addition, it takes more than just the burner orifices to convert a grill safely. With any gas appliance, always err on the side of caution and safety.

Weber no longer offers or support conversion kits. If you do any conversion it will VOID you warranty!

That said, if you can find the parts online for the LP version of your grill you can convert it yourself if you are mechanically inclined.

You will need to change the JETS and the GAS REGULATOR. Unfortunately they do not sell official Weber Gas Jets alone. You will have to by the complete LP Manifold, valves and all as well as the Tank Hose with Regulator...

Make sure you are comfortable with all of this... Leak testing etc...

Weber stopped selling conversion kits due to some legal action in 2008. There are no longer kits available. What you would have to do to covert it is order a replacement gas valve for the NG version of your grill just to get the orifices. Then you have to replace the LP regulator with a NG regulator. Typically most NG grills do NOT have a regulator but local building codes will require a NG regulator and a different gas line hose.
Conversion of a BBQ gas valve to NG is a matter of drilling out the orifice to a larger hole in an LP orifice.
You will not find anyone that will perform this conversion for you due to legal liabilites.
If you want to convert it... you will either have to order the whole gas control valve for NG or drill out the orifices yourself in your current gas valve hoping your got the orifice hole size correct when you drilled it. Mind you all liability for doing this lies solely with you.

Sorry, but there are no conversion kits available for Weber Grills. They were no designed, tested or approved to be converted from one gas type to another.

For confirmation of the this, see FAQ link to Weber, below.

Weber does not sell a conversion kit. They wont sell due to liability reasons. But to answer your question you need to change all the burners, controls, and you will need to remove regulator and replace with hose to ng outlet. NG has a regulator where NG is attached to house..

Weber does not sell conversion kits. They sell either lp or ng grills. They say the liability is to high to have someone convert grill. No parts available have to buy new grill.

On the weber model you need to purchase the natural gas model. It will cost you alot more to buy all parts needed to convert. Weber doesnt want you to convert do to safety reasons. This is why they will only tell you you can't convert. Buy the right grill and save yourself a headache.
