Meta Description: Thinking about switching your gas appliances from natural gas to propane (LP)? Learn everything you need to know about natural gas to LP conversion kits, including types, installation, safety, and cost. We'll guide you through the process, helping you make an informed decision. This comprehensive guide covers everything from choosing the right kit to ensuring safe and proper installation.

Understanding Natural Gas and LP Gas

Before diving into conversion kits, let's clarify the differences between natural gas and liquefied petroleum (LP) gas, often called propane. These gases differ in their chemical composition and pressure, necessitating a conversion for appliances designed for one fuel source to use the other.

Natural Gas

Natural gas is a low-pressure fuel typically delivered through underground pipelines directly to homes and businesses. It's widely available in many areas but not universally.

LP Gas (Propane)

LP gas, stored in tanks, provides flexibility for areas lacking natural gas pipelines. It's also a popular choice for recreational vehicles (RVs) and off-grid applications. Propane's higher energy density means it burns hotter than natural gas.

Why Convert from Natural Gas to LP?

Several reasons may prompt a homeowner or business to convert gas appliances from natural gas to LP:

Relocation: Moving to an area without natural gas access often requires converting appliances to propane.
Off-Grid Living: Propane provides a reliable fuel source for those living outside traditional utility grids.
Backup Fuel Source: Having propane as a backup ensures continued operation during natural gas outages.
Cost Savings: In some regions, propane may be more cost-effective than natural gas. (This is location-dependent and should be researched locally.)

Types of Natural Gas to LP Conversion Kits

Conversion kits are available for various gas appliances, including:

Stoves and Ovens: These kits typically involve adjusting orifices (small openings controlling gas flow) and potentially replacing other components.
Water Heaters: Similar to stoves and ovens, water heater conversions focus on adjusting gas flow and ensuring proper burner operation.
Furnaces and Boilers: These conversions often involve more extensive modifications, potentially requiring professional assistance.
Fireplaces and Fire Pits: These conversions can range from simple orifice changes to more involved regulator adjustments depending on the design of the appliance.

How to Choose the Right Conversion Kit

Selecting the correct conversion kit is crucial for safety and appliance performance. Here's what to consider:

Appliance Model Number: This number, usually found on a label, is essential for finding a compatible conversion kit.
Kit Compatibility: Ensure the kit is explicitly designed for the specific appliance model and the transition from natural gas to LP.
Manufacturer Reputation: Choose kits from reputable manufacturers with a history of quality and safety.

Installing a Natural Gas to LP Conversion Kit: A Step-by-Step Guide (General)

Caution: Improper installation can be dangerous. If you're uncomfortable performing the conversion yourself, consult a qualified gas appliance technician.

These steps are generalized and should be adapted to the specific instructions provided with your conversion kit.

Safety First: Turn off the gas supply at the main shutoff valve before beginning any work.
Locate Orifices: Identify the gas orifices on your appliance. These are small openings where gas flows out.
Replace Orifices: Carefully remove the old orifices and install the new ones provided in the conversion kit, ensuring correct orientation. The kit instructions will specify the proper size.
Adjust Regulator (if necessary): Some kits may require regulator adjustments to manage the different pressures of natural gas and LP gas.
Check for Leaks: After installation, use soapy water to check for gas leaks around all connections. Bubbles indicate a leak requiring immediate attention. Never use an open flame to check for leaks!
Relight Pilot Light (if applicable): Carefully follow the instructions for relighting the pilot light on your appliance.
Test Appliance: After ensuring there are no leaks, carefully test your appliance to ensure it's functioning correctly.

Safety Precautions

Proper Ventilation: Ensure adequate ventilation in the area where the gas appliance is located.
Professional Installation: For complex appliances like furnaces and boilers, professional installation is strongly recommended.
Leak Detection: Regularly check for gas leaks using soapy water. Any leaks should be addressed immediately by a qualified technician.

Cost of a Natural Gas to LP Conversion Kit

The cost varies depending on the appliance type and the complexity of the conversion. Simple conversions might cost as little as $20 for the kit itself, while more complex jobs could require hundreds of dollars, including professional installation fees.

Frequently Asked Questions (FAQs)

Q: Can I convert my gas appliance myself?

A: For simple appliances like stoves, you might be able to perform the conversion yourself, but it is important to strictly follow the manufacturer's instructions. Always prioritize safety. For more complex appliances, professional installation is recommended.

Q: How often should I check for gas leaks?

A: It is advisable to perform a leak check at least annually, if not more frequently.

Q: What happens if I install the wrong conversion kit?

A: Installing the wrong kit can lead to dangerous situations, including gas leaks, improper combustion, and appliance malfunction. It's crucial to use the correct kit for your specific appliance model.

Q: Where can I buy a natural gas to LP conversion kit?

A: Conversion kits are available from home improvement stores, online retailers, and appliance parts suppliers.

By following this comprehensive guide, you can confidently approach the conversion of your natural gas appliances to LP. Remember to always prioritize safety and, when in doubt, consult a qualified professional.
