    I almost bought a Ducane last night and the guy tells me I can't convert from LP to Gas or viceversa. He lost the sale and I'm still grillless.

    I have a Holland grill that was originally natural gas. I had it converted to LP but it takes FOREVER to **** anything. I have checked the little holes on the burner, all open and functioning well.

    Our natural gas hot water tank & furnace with Air Handler (no AC) leaks after cleaning evaporation coil. Pan under coil overflows & can't tell if there is a drain somewhere that is clogged, but no visible leak in coil or plumbing. What could it be?

According to the dealer, you are supposed to change the valves when converting. They do sell NG and LP valves but I don't know what is different.

I want to convert my Ducane to NG and trying to decide if I should just buy another grill.

I converted a Sam's Club Members Mark grille last year and just did some research on the internet and found a numbered drill size chart that gave me the correct drill size to use on each burner(side,main and rear)for the proper BTU supply for the size or BTU rating for your burner. I drilled them, All has worked well! I know Ducane will tell you not to do that, but I think it is a legal issue. If you have a problem, they don't to get a letter from your lawyer.

Convert gas grill natural

ducane will not make these available anymore because the ducane family no longer owns the company and the models since 2007 are all made in china with poor quality controls. conversions are simple but the parts will not come through ducane or weber. replace the orifice in the tip of every control valve and replace the regulator. that is the only difference in fuel types.

Do they make a conversion kit from NG to LP for a Ducane Meridian 32" grill ???....btw, the model has been discontinued.

Unfortunately, there is not a conversion kit available to convert a Ducane/Webber Grill from one gas type to another. In fact, there never has been, to the best of my knowledge.

The reason for this is that each model is tested and approved for a specific gas type. Whether it's Natural Gas or Propane Gas. Attempts to convert them from one gas type to another would then place all the liability on you, if something should go wrong, because of the conversion. Even the Owner's Manual states that.

My best advice, is clean the grill up and sell it to someone who wants a Natural Gas Grill. Use that money to put toward a new LP Gas Grill. That's the safest way to do it.

I hope this helped you and thanks for choosing FixYa.

Looking for a grill cover that will fit the DUCANE 30400042 Gas Grill

Home depot or Lowes will have it, that's where I got mine. Of course if you want the one that says Ducane on it they will charge you 3 times as much at the high end grill store. Look on ebay, sometimes they and Amazon shock the heck out of me
