An LP (liquid propane) gas conversion kit is a set of adapters that enable natural gas appliances to operate with propane gas lines. If your new appliance didn't come with a conversion kit, you'll need to purchase one specific to your appliance. This process can be complex, and if you encounter difficulties or cannot access the pressure regulator, it's advisable to seek professional assistance. Additionally, when converting a stove, ensure both the stovetop and oven range are converted before reconnecting to the gas line.
Steps
Important Safety Measures
Choose the Right LP Gas Conversion Kit for Your Appliance. If your appliance came with an LP conversion kit, use it.
For third-party LP conversion kits, carefully read the instruction manual and labels to ensure compatibility with your specific appliance. Remember, these kits are not universal, so verify that your kit matches your appliance.
Some appliances feature built-in conversion kits where you can adjust certain screws or nuts to alter the gas output. If you have a new appliance without a conversion kit, it might have built-in converters.
This process involves manipulation of your appliance’s gas lines, so without the correct adaptor kit and instruction manual, it's unsafe to proceed.
For converting the gas source of a water heater or HVAC system, it's crucial to hire a professional due to the high risks associated with errors.
Prioritize safety by unplugging your appliance before any maintenance work. Ensure to check for any additional power sources mentioned in the manual.
Securely shut off the gas supply and disconnect the hose to prevent accidents. Always ensure the gas valve is fully closed and contact your utility company if there are any concerns.
Attention: Clothes Dryer
Consult your appliance manual to locate and adjust the pressure regulator as needed. For complex tasks, consider hiring a professional technician for assistance.
Accessing the pressure regulator may require removing panels. Follow manual instructions or seek online tutorials for assistance.
To prevent electric shock, remove any cable connections near the regulator. Disconnect cables by sliding them out of their connectors.
Detach the dryer burner by unscrewing it and pulling it out. The burner connects the regulator to the drum, and swapping the orifice underneath is necessary for conversion.
Unscrew the existing regulator orifice using a wrench. This orifice controls gas flow and needs replacement for propane conversion.
Apply thread sealant to the threading on the new orifice. Spread a thin layer of sealant using a brush to prevent gas leakage.
Install the new orifice into the pressure regulator and tighten it with a wrench. Ensure proper tightening to prevent gas leaks.
Adjust the pressure regulator’s hex cap according to your appliance’s instructions. Look for a small screw on top of the pressure regulator, usually made of plastic. Refer to your manual to determine the direction for turning the cap. Typically, you'll need to use a screwdriver or wrench to rotate the hex cap clockwise by one full turn to restrict gas flow. This adjustment controls the amount of gas the pressure regulator holds, so follow your appliance’s manual carefully to set it correctly. You might find a plastic cap atop the hex cap for protection, which can be removed with a flathead screwdriver. In some dryers, you may need to unscrew the hex cap entirely and reinstall it in the opposite direction.
Reassemble the burner and dryer panels to complete the conversion process. After replacing the orifice and adjusting the hex cap, slide the burner back in place and secure it with screws or nuts. Reconnect any cables, matching the color-coded wires. Finally, reinstall any removed panels. Remember to fully reconnect the gas hose before reopening the gas valve. If you detect a gas odor when not using the dryer, contact your utility company immediately and engage a service technician for repairs.
Stovetop
Remove the grates and orifice covers from each burner. Lift off the metal grates and remove the covers concealing the orifices. These orifices, small gold cylinders under each burner, need replacement. Depending on your stove, you may lift the covers or unscrew them counterclockwise. Ensure you remove all covers, typically one for each burner. Converting a stove involves replacing the orifices under each burner and adjusting the pressure regulator and burner in the range. You can start with the stovetop orifices or the regulator and burner interchangeably.
Use a socket wrench to remove the old orifices. Find a socket wrench that matches the size of the orifices within each burner. To prevent orifices from falling during removal, place a small piece of tape inside the socket wrench. Unscrew each orifice carefully and lift them out of the stove. Ensuring the orifices don’t fall during removal prevents inconvenience and potential difficulties in retrieval.
Follow the instructions in the conversion kit to determine the placement of each orifice. Typically, the kit provides several orifices for the stovetop, each coded by color. Refer to the accompanying chart to correctly install each orifice on your stovetop burners. The variations in orifices account for differences in gas travel distance to each burner, including a separate simmer burner. Consult the provided chart for accurate installation guidance.
Install the conversion kit orifices onto your stovetop using a socket wrench. Place a piece of tape inside the wrench, then attach the orifice with the threading facing downward. Carefully insert and screw the orifice into each burner opening, ensuring a snug fit. Repeat this process for each burner. Once the stovetop orifices are replaced, proceed to adjust the pressure regulator and replace the burner orifice.
Complete the stovetop assembly by reattaching the orifice covers and grates. Slide the covers back onto the stove and secure them. Then, position the grates back over the burners. Remember, before using the stovetop with a propane gas line, you must also convert the regulator and burner within the oven range.
Oven Range
Simplify the process by removing the oven range door. Consult your oven’s manual for instructions on door removal, typically involving lifting it out of its bottom frame slots after partially opening it. The range, located beneath the stovetop, is where you bake and broil food. After removing the door, take out the metal shelves from inside the range.
Remove the base of the oven range to reach the burner. Inside the oven range, there's likely a flat metal floor. Slide it out of the slots or unscrew it from the corners to remove it. This grants access to the burner. If the pressure regulator is under the burner, remove the stove's bottom drawer or unscrew and remove the back panel.
Remove the burner from the frame to access the regulator's orifice. The burner is a long metal bar in the middle of the range. Slide it out from the slots or unscrew it if necessary. The gas feeds into the pressure regulator, which then supplies gas to the burner for ignition and heat production. You may need to remove a metal cover from the burner.
Replace the orifice on the pressure regulator. The pressure regulator, a bulky assembly, has an orifice that feeds into the burner. Unscrew the existing orifice and replace it with the one from your conversion kit. Adjust the size of the orifice opening to match the gas type to maintain consistent temperatures.
Convert the gas by adjusting the hex cap. The hex cap on the pressure regulator controls gas flow into the oven. Consult your oven’s manual for specific instructions. You may need to flip the hex cap or tighten it to convert it for propane. Access the hex cap, which may be beneath the oven.
Adjust the burner screw to convert the gas. Loosen the screw on the end of the burner and slide it to align with the appropriate setting for your gas type. Tighten the screw in place. Repeat this process for the oven range's broiler if applicable.
After reassembling the burner, reinstall the range base. Slide the burner back into the base of the oven range, ensuring the orifice feeds into it. Then, place the base panel over the burner and regulator, sliding or screwing it into position. Reattach the gas hose and plug in the oven before sliding it back into place. If you detect gas odor when not using the stove, contact your utility company and a service technician for inspection.
TipsWhen converting a propane appliance to natural gas, use a NAT conversion kit, not an LP conversion kit. The conversion process varies based on the appliance's brand and model, emphasizing the importance of following the instruction manual carefully.
Converting a radiator or water heater from natural gas to propane, or vice versa, requires professional assistance. Attempting it yourself risks serious consequences, including gas leaks and potential explosions. Always prioritize safety and seek professional help for such conversions.
