To convert a gas stove to propane, you needs a kit designed specifically for this purpose. Converting to propane may be necessary when a family moves from one home to another and the local utilities do not offer natural gas services. The conversion process is relatively simple, and propane tanks can be delivered and installed almost anywhere outside the residence and refilled at regular intervals.

Simple tools are needed to convert a gas stove to propane, and a set of screwdrivers and a wrench are usually all that's needed. New stoves typically come with a kit to covert them from gas to propane, but they may be available for purchase separately as well.

Using a kit helps ensure that the conversion will be done correctly and that the stove will function properly. Natural gas and propane burn at different rates, so controls are needed to maintain the proper amount of gas being burned. The amount of gas delivered to the flame will be regulated by a color coded orifice at each burner, which is simply a fitting sized for the appropriate type of gas.


Once the orifices are installed, locate the gas regulator, which is found under stove cover. There is a cap on the gas regulator that must be removed and then refitted using the opposite side of the cap. Another adjustment must be made on the main burner tube where it enters the stove. This is another orifice that must be turned clockwise with a wrench until it cannot be turned further. If there is a broiler orifice, it must be adjusted in the same way.

Next, connect the gas line to the stove. If the connection is threaded, it is important to use pipe tape or thread compound to ensure a tight fit. In the case of threaded connections with flare cones inside the female ends, it is best not to use any tape or compound.

Once the gas is connected, check for leaks before trying the stove. This is done by mixing a solution of soapy water with 0.5 cup (118 ml) water and a drop of dish detergent. Apply a small amount of the solution on the propane connection. If bubbles form in the soapy mixture, the connection must be reseated. If no bubbles appear, the connection is tight. Once this test is complete, it is safe to test the propane stove and ensure that it is working properly.

I'm not sure if this can help you guys or not, but I was really on the verge of giving up on deciding about using propane conversions, but I think somehow I found the answer.

I am a newbie here but I would just like to share my experience, since some people might feel the same way. At first I was a bit doubtful if converting gas to propane would really fit my expectations, but I've come to realized that yes, it is the answer for my longing prayers. It's very affordable, convenient and is truly a lifesaver. I don't need to spend too much on gasoline and I enjoy the perks of saving my precious time and energy.

There are good references online for your concerns about propane conversions.

I read your blog post. It was very informative As I am a regular user of propane, I like to enhance my knowledge about propane. I would request the writer of this blog post to create a page on Facebook and share this posts and other similar posts written by him there. -- Stephen B.

Just to make it simple: NG has lower heat value for same burner sizes, and you should not put propane in this burner as is.

The main conversion issues are:

1- The supply pressure into the main valve is higher in the case of switching to LP, so that means another regulator must be used.

2- The orifice at the burner input should be reduced.

3- The air/gas mixtures should be adjusted (in LP the amount of air is the same, but the volume of gas is 1/3)

4- The small holes around the burner head, where the flame is issued, should be smaller, otherwise the gas-air mixture speed is reduced and one could have a back fire into the body of the burner (in venture type burners).

5- The CO should be measured and controlled to prevent poisoning the surrounding area. I'd do it with an original parts kit.

I'm having problems converting my kenmore gas stove to LP. I convert the burners on top, but if I turn all them at the same time the flame get smaller on some of the burner. The flame is blue which is good. I also having problem with the oven burner. I flip the part inside the regulator already. No fire in the oven yet. I'm having problems with the burners in the oven. I can't get it to work.

@daphne: If you're seeing yellow in your flame, your orifices need cleaned (an air hose normally works for that). When properly fitted there should be no difference, but it's always wise to watch your flame as you adjust, and not merely the dials.

@anon38167 - I would consult a professional before trying to convert to natural gas. It is so hazardous, you do not want to mess around with it! It would have to be connected directly to your gas line

something to be aware of when switching from one to the other is that natural gas burns hotter than propane. If you are used to cooking with gas, you will that water, for instance, will take longer to boil on a propane burner than on a natural gas stove burner.

Conversely, if you are used to grilling with propane, you should be careful when switching to natural gas as your food may cook more quickly than you're used to. You can actually see it in the flame. A propane flame will have some yellow in it, while a natural gas flame should be all blue (meaning it's hotter).
