Converting Natural Gas Deep Fryers To Propane: Is It Possible?

Converting a natural gas deep fryer to propane is a complex process that requires careful attention to safety. While it is possible to make the switch, it is highly recommended to consult a professional technician to ensure a safe and proper conversion. The process involves several steps, including replacing burner orifices, pilot orifices, and the gas regulator. Additionally, combination safety valves and the unit's nomenclature must also be replaced to complete the conversion. This can be achieved through the use of a conversion kit or by purchasing individual parts. It is important to note that using a natural gas fryer with propane is extremely dangerous and should be avoided.

Burner orifices need to be replaced

When converting a natural gas deep fryer to propane, one of the key components that need to be replaced is the burner orifices. This is because the burner orifices are designed specifically for the type of gas being used, and the difference in pressure between natural gas and propane means that the wrong orifice can lead to malfunction and potentially dangerous situations. Natural gas operates at a much lower pressure than propane, and as a result, natural gas orifices are larger than propane orifices. If propane is used with a natural gas orifice, the higher-pressure gas flowing through the larger orifice will result in an excessively large flame. On the other hand, using a propane orifice with natural gas will result in a very small or non-existent flame due to the lower pressure and smaller orifice.

To replace the burner orifices, you will first need to know the brand name, model, and serial number of your deep fryer, as well as its altitude, which will determine the size of the orifice you need. You can then source the appropriate orifices either through a manufacturer's conversion kit or by purchasing individual parts. It is worth noting that conversion kits tend to be more expensive than buying individual parts. Once you have the new orifices, you will need to dismantle the deep fryer to access the burner valves. Remove the old orifices and install the new ones in their place, screwing them to the end of the valve.

It is important to note that converting a natural gas deep fryer to propane is not a simple task and should not be attempted without proper knowledge and equipment. It is highly recommended to consult a professional technician when attempting any type of gas conversion to ensure safety and proper functionality.

Gas valve regulator needs to be replaced

Yes, it is possible to convert a natural gas deep fryer to propane. However, it is dangerous and should not be attempted without professional help.

When converting a natural gas deep fryer to propane, the gas valve regulator is one of the three items that need to be changed, along with the burner orifices and the pilot orifice.

• Turn off the gas supply to the valve. This is a crucial step to ensure safety during the replacement process.
• Locate the gas cock dial and turn it to the "off" position. This will prevent any accidental release of gas during the procedure.
• Remove the screws that hold the standard regulator cartridge and gasket in place. It is important to keep these screws in a safe place as they may be needed again later.
• Carefully remove the existing regulator and gasket. This step may require some force, but be gentle to avoid damaging any surrounding components.
• Install the new gasket and regulator. Ensure that you follow the manufacturer's instructions or those provided by a professional. Use the new screws that should be supplied with your conversion kit.
• Once the new regulator and gasket are securely in place, you can restore the gas supply.
• Finally, test the new setup for any leaks. This can be done using a leak detector solution or a soapy water solution, which will bubble if there is a leak.

It is important to note that converting a natural gas deep fryer to propane requires some special equipment and technical knowledge. Therefore, it is highly recommended to consult a professional technician when attempting any type of gas conversion to ensure safety and proper functionality.

Pilot orifice needs to be replaced

When converting a natural gas deep fryer to propane, you will need to replace the pilot orifice. This is because the pilot orifice is designed specifically for natural gas, and using propane gas with the wrong orifice can be very dangerous and should not be attempted.

The first step is to identify the brand name, model, and serial number of your deep fryer. This information is crucial as it will determine the specific parts needed for the conversion. Additionally, you need to know the altitude at which the fryer will be used, as this will influence the orifice size required.

To replace the pilot orifice, start by unscrewing the nut that attaches the pilot tube to the pilot. Once the nut is removed, pull the tube out of the pilot assembly. The orifice should fall out; if it does not, gently tap the pilot assembly. Install the new pilot orifice designed for propane gas, and reassemble the pilot following the reverse order of disassembly.

It is important to note that converting a natural gas deep fryer to propane requires specialized knowledge and equipment, particularly when it comes to ensuring proper gas pressure. Therefore, it is highly recommended to consult a professional technician or your local restaurant equipment technician to perform the conversion safely and correctly.

Gas pressure needs to be checked

Gas pressure is a critical factor in ensuring the safe and efficient operation of a deep fryer. When converting a natural gas deep fryer to propane, it is essential to check and adjust the gas pressure to ensure optimal performance and safety. Here are some detailed instructions on why and how to check gas pressure during the conversion process:

Gas Pressure Requirements

Propane gas has a higher energy density than natural gas, meaning it requires precise control to ensure safe combustion. The gas pressure needs to be set correctly to supply the right amount of propane to the fryer burners. Too low or too high pressure can lead to incomplete combustion, affecting cooking performance and potentially causing hazardous situations.

Specialised Equipment

Checking and adjusting gas pressure typically requires specialised tools and knowledge. It is recommended to consult a professional technician or restaurant equipment specialist who has the necessary equipment and expertise. They will be able to accurately measure the gas pressure and make any necessary adjustments to ensure the fryer operates correctly and safely with propane.

Gas Pressure Adjustment

The gas pressure adjustment process may vary depending on the fryer model and the conversion kit used. In most cases, the gas regulator, which controls the gas flow, will need to be adjusted. The regulator is usually located at the back of the fryer and has an arrow indicating the gas flow direction, which must point towards the fryer. The gas pressure is then adjusted using a regulator dial or screw until the optimal setting is achieved.

Leak Testing

Once the gas pressure has been adjusted, it is crucial to perform a leak test to ensure there are no gas leaks. This can be done by applying soapy water to the gas connections and looking for bubbles, which indicate a leak. If leaks are detected, tighten the connections and perform the test again until no leaks are found.

Safety Precautions

Working with gas appliances requires strict adherence to safety precautions. Always ensure the gas supply is turned off before performing any maintenance or conversion work. Follow the manufacturer's instructions and safety guidelines provided with the conversion kit. Do not attempt to use the fryer until a qualified technician has checked and approved the gas pressure and burner settings.

By carefully checking and adjusting the gas pressure, you can ensure that your converted deep fryer operates safely and efficiently with propane. Remember to consult a professional for assistance if needed, as they have the necessary tools and experience to complete the conversion process correctly.

Conversion kits are available

There are a few different options for conversion kits, depending on the make and model of your fryer. For example, if you have a Pitco Model 14, you can use kit B751008 to convert from natural gas to propane. If you have an American Range model AF-45, you'll need to purchase separate items: a Valve Conversion (RSW), Burner Orifices, and a Pilot Orifice. Frymaster and Pitco also provide kits with all the required items.

Conversion kits typically include items such as burner orifices, a gas valve regulator, and a pilot orifice. In addition to the kit, you'll also need to know the brand name, model, and serial number of your fryer, as well as the altitude it will be used at, in order to determine the correct orifice size.

The conversion process involves dismantling and reassembling the fryer. You'll need to remove the burners, access the burner valves, and replace the old orifices with the new ones. You'll also need to replace the pilot orifice and the gas regulator, ensuring that the gas flow direction is accurate. It's important to note that you should always turn off all gas to the unit before beginning the conversion process.

While it is possible to purchase individual parts for the conversion, it is recommended to use a manufacturer's conversion kit to ensure safety and compatibility. These kits are designed to work with specific models of fryers and come with instructions for installation.

Converting a natural gas deep fryer to propane can be a complex process, and it is always recommended to consult a professional technician when attempting any type of equipment conversion.
