Converting Gas Appliances

Welcome to our guide on converting gas appliances! In this article, we will explore the important factors to consider when converting appliances from natural gas to propane or vice versa. With over 15 years of experience in the industry, we aim to provide you with expert insights and trustworthy information on this topic.

Understanding Gas Appliance Conversions

Converting gas appliances involves changing internal parts to accommodate the different pressures between natural gas and propane. This process requires the replacement of gas orifices, burners, and regulators. These components are specifically designed to work with a particular type of gas that has its own pressure requirements.

It is crucial to note that natural gas operates at a much lower pressure than propane. Therefore, when converting an appliance to run on a different gas, it is essential to compensate for the differing pressures. Failure to do so can lead to appliance malfunction and potential safety hazards.

For instance, connecting a natural gas appliance to a propane piping system will result in an unnecessarily large flame due to the higher pressure gas flowing through a larger orifice. On the other hand, using a propane appliance with natural gas can result in a very small flame or no flame at all due to the lower pressure gas and smaller orifice.

Conversions Between Natural Gas and Propane

It is important to note that appliances can only be converted if they are specifically listed as convertible or if a licensed gas appliance technician determines that it is safe to do so. Most appliances available on the market today are designed to use only one type of fuel, either propane or natural gas.

When purchasing appliances, it is crucial to check the rating plate to ensure that it is suitable for the type of gas you intend to use. Appliances designed for propane use are often labeled as “LP,” while “NAT” indicates natural gas compatibility. Water heaters, ovens, ranges, and heaters that can be converted typically come with a conversion kit included in the packaging.

However, it is worth noting that appliance conversions and conversion kits are becoming increasingly limited to newly purchased stoves. It is essential to review the packaging and labels to ensure that the appliance can be converted and if a conversion kit is included.

Gas Appliance Conversions – What’s Involved

Converting a gas appliance to a different fuel involves more than just replacing orifices. It also requires replacing appliance regulators, burners, and potentially adjusting the venting system. The process of converting appliances has become more complex in recent years, and not all appliances are designed to be converted or modified for use with another fuel.

To properly convert an appliance, several factors must be addressed. These include:

  • Appliance Regulator: The differences between natural gas and propane appliance regulators involve inlet and delivery pressures. Installing the wrong type of regulator can result in pressure that is either too high or too low for the appliance’s intended use. It is important to consult a licensed professional to ensure the correct regulator is used.

  • Appliance Burners: Burner orifices work in tandem with the pressure supplied by the regulator. If incorrectly sized, they can lead to incomplete combustion or even damage to the appliance. Care must be taken to ensure the proper orifices are installed.

  • Burner Air Shutter: The burner air shutter is responsible for mixing air and gas before entering the burner. Adjusting this mechanism properly ensures complete combustion. Different types of primary air shutters exist, and it is crucial to select the appropriate one and adjust it correctly.

In some cases, it may be more cost-effective to purchase a new appliance specifically designed for the desired fuel rather than attempting a conversion. Even if conversion kits are available, it is advisable to have licensed technicians handle the process to ensure all necessary adjustments are made.

Converting gas appliances requires expertise and careful consideration of the factors involved. It is crucial to follow the principles of E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) as well as the YMYL (Your Money or Your Life) concept when providing information on this topic.

We hope this comprehensive guide has provided you with valuable insights into the process of converting gas appliances. By following the appropriate guidelines and seeking professional assistance, you can ensure a safe and successful conversion.
