Natural Gas Vs Propane Valve?
Question:What is the purpose of the LNG Vs Propane Valve that has to be installed on Gas Stoves/Ovens before use ? How can I set it myself for Propane ? What negligible effects would I experience if I hook a stove up to Propane while the valve is set-up for LNG ?
Thank You !

LP gas and natural gas work off of two different pressures. Usually there will be a inner spring that need to be changed out inside the valve, and the orifice will need to be changed as well. If you don't convert your valve, it can prove to be very dangerous! Most likely it will only have an erratic flame, and burn very dirty. The flame will burn out of control and have orange color to it. However, it could result in not burning off all of the gases as they are released, and could cause an explosion. Most of the time in the owners manual it will have step by step instructions on converting LP to Nat, or vise versa. Remember, gas is a safe alternative to electricity, but if not handled correctly it can be very dangerous. Please proceed with care, or if you are uncertain with yourself, call a qualified technician. It shouldn't take em more than an hour, and most techs charge around 60 bucks an hour. A cheap price for a job done safely.
The difference is the size of the orifice. I've never changed it myself but I don't think it could be too difficult, however I've always had a professional do it for me.
The reason for this is that propane and natural gas (methane) have very different Btu contents. Propane has a much higher Btu content and the orifice for propane is smaller. There is also a small difference in pressures of the supplied gas as pointed out below, but it is small. If you hook up propane while having the natural gas orfice installed, you may experience problems with incomplete combustion (soot) and the appliance getting hotter than design due to too many Btu's.
LNG (Liquid Natural Gas) is a cryogenic form of methane. It is generally stored at -250 deg F. It is not used for domestic fuel.
They are two different burners, with different ignition characteristics, and CANNOT be used for both gases.

Safety first! Done.
Gas ovens, and furnaces on natural run at 3.5 inches of water column and propane is at 10.5 inches of water column. Therefore the pressures are different. If you were to run a natural stove on propane you would be eating soot, and it would end up on your walls backsplash, inside the oven etc. This is to be done only by a professional
the reason for the difference in orifice size is pressure, not btu! propane is highly pressurized and uses a smaller jet. they use the same burners, so change the jets,, it is usually easy unless you have one of those that require a special tool,,
