My left burner is much hotter then the right burner on my 1504 Natural Gas Grill. Please adivise

Did he change the reg as well ??

Jim, the reason Napoleon no longer sell a gas conversion kit is a matter of safety. None of their grills are approved to be converted from one gas type to another. Which is also the case with 95% of all the grill brands on the market today. Grills are tested and approved for the gas type they represent. Changing the gas type, then puts the burden of liability on you, if something should go wrong.

Most people want to convert them, as a matter of convenience. Not having to deal with refilling the LP gas tank. But, are disappointed with the operation of the the grill, once it's converted to Natural Gas. As, it takes longer to preheat the grill and the flame height of the burners is lower than with LP Gas.
The reason for this is that LP Gas burns cleaner & hotter in an outdoor environment than Natural Gas.

There are no complete conversion kits available. If, in the end, you decide to make the conversion, you will need to piece and part a kit together. And that's not including running a hard line to the grill's location., along with an inline gas shutoff valve and a quick disconnect gas hose to the grill.

I hope this helped you to make the right decision and err on the side of caution and safety.

Thanks for choosing FixYa and Happy grilling!!

Unfortunately, Weber grills are not convertible from one gas type to another. There are no conversion kits available for your model or any Weber model gas grill.

To confirm this, go to the following link and on page 2 under Warnings, last paragraph, left hand column, you can confirm this, if you like.

The only advantage to converting it to Natural Gas is not having to refill the grill tank. The downside, is that you will loose the heating capability that Propane has. It burns cleaner and hotter than Natural gas, in an outdoor environment.

Hope this helped you. Happy Grilling!!

If you didn't change the burner orifices to Natural Gas orifices, that's the problem. Even after those are changed (assuming you didn't) the grill will take a bit longer to preheat. As Propane burns cleaner and hotter than Natural Gas, in an outdoor environment.

Hope this helped answer and solve the problem for you.

I don't believe Weber makes a gas conversion kit for your model grill. I say this, because your model grill comes two ways, Natural Gas or Propane. This indicates to me, that there's more than just changing the burner orifices involved.

I can tell you this ... If you could convert it to Natural Gas, you would soon discover that the grill doesn't preheat as fast as with propane. Nor, will it maintain heat as well as propane, in an outdoor environment. Propane burns cleaner and hotter than Natural Gas in an outdoor environment.

Sure, it may seem like a hassle to refill and change the tank, but I can assure you, you won't be satisfied with it's performance.

Hi,
You problem could be or probably is with the regulator...not enough gas pressure...

Propane, LP, or Natural Gas Regulator Problems

Is this grill new? How many burners are on this grill? Typically if there is a pressure problem, the farthest burner from the regulator suffers. Looking at the photo of the grill, the tank and regulator are on the right, which would make the left side burner weaker. The flames can be even all around each burner, but if the burner on the right has slightly taller flames than on the left, even increasing the pressure won't "even" it out, it would just make both bigger. It could be just the nature of the beast. If it was feasible and the left and right burner were identical, it would be interesting to see if switching the burners would make any difference. Check to make sure each burner's air shutter adjustment is the same and adjust each for the bluest flame possible. Look for spiderwebs, bugs, or rust debris and blow out with air compressor, if possible. Let us know if you need more assistance. Good luck!

To convert your grill you will need the part # 37800 You can get it on the link below. Half way down

Good Luck

gas regulator make sure all burners are off when you connect bottle... the units have a leak sensor and will stop the gas coming out because it thinks you have a leak when you connected the bottle. now try hooking up the bottle again with all the burners closed incl. the side burner and the infa red. It will work o.k. then

It's safe, but you need to keep in mind that propane burns hotter than natural gas, so you won't need to turn the burners up as high for the same heat. Here's an article that explains some of the differences (but doesn't really answer your question): http://bbq.about.com/od/gasgrills/a/aa030505a.htm

Bottom line -- it's safe if you don't leave it cranked up to high flame. Two-thirds flame on propane should give about the same heat as full burner on natural gas.

Of course, you could change the jets. That would compensate for all the differences between NG and propane, and you could run the grill on full high heat if you wanted to.
