Does conversion from LP gs to Natural gas on Ducane 30400040 (essentially makes it a model 30400041) require changing the inlet orofice on the IR burner ? I purchased conversion kit that included all new valves, manifold and igniters for main, side & IR burners. All works well but IR Burner will not light with either igniter or match.

check with manufacturer or online for a conversion kit

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.

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.

Hi,
Your problem could be or probably is with the regulator...not enough gaspressure...

Perhaps, the reason you can't find the fuel conversion parts is that they are not convertible from one fuel type to another. Ducane/Weber makes both an LP model and a Natural Gas model of your grill, but no conversion kits. Because, as the Owners Manual states "Liquid propane gas is not natural gas. The conversion or attempted use of natural gas in a liquid propane unit or liquid propane
gas in a natural gas unit is dangerous and will void your warranty."

Certainly, you could attempt it, Marlin . But it's not the wise thing to do.

I know this wasn't the answer you may have wanted, but I hope it helps you.

Check Home Depot or Lowes for a conversion kit.

Good Luck

Try blowing the burner out with compressed air. They're not adjustable but can get clogged up and change the air to gas mix.

goto ducane web site http://www.ducane.com/manuals/
and download manual. They have Meridian and Stainless models in 3 & 5 burner for LP & NG. Follow 1 year cleaning instructions. Pictures and instructions.
