Convert Weber Genesis B Grill To Natural Gas?

Question

I purchased a new Weber grill at Lowes as they were on clearance for a good price, with propane setup.

They did not have natural gas and would have to special order at a premium so I got the propane at a clearance price.

The propane works fine, but I'd like to eventually convert this grill to natural gas as I have a handy tap.

The grill has three burners, each 12,000 BTUs. Can anyone guide me on the drill/orifice number for NG at 12,000 BTU? Any funny stuff with Weber controls that would prevent conversion by orifice re-sizing?

Thanks Tom

Hi,Makes sense. NG has less BTU per volume. Orifice change alone may notbe enough.Tony

The burners are not different for NG and LP.They are the same part no.The manifolds have different part nos. and it is in the manifold wherethe flow orifices reside.Tom

Strange, I checked into this a couple of years back, and was shown differantburners, nozzles and the like, in conversion kit from Weber. I was told theburners needed to be changed.Greg

The new units have the same burners..#20428 for the ones we have converted for customers who recently got NG at their homes. The manifold has to be changed, and a secondary reg needs to be put on...personally, I would have just bought the NG unit to start with.

Contact Weber and ask them what parts are needed for a safe conversion to ng from propane. It may involve more than just another sized orrifice. If so, the money you saved on this grill may be eaten up paying full price for conversion parts. May end up costing you more than a new ng configured grill, but you never know. Worth looking into, at least.
