DIY Gas Fire Pit: How to Use Manual On/Off Valves

When building a DIY gas fire pit, having the right manual on/off valve is crucial for controlling gas flow, ensuring safety, and creating a seamless fire pit experience. Firepit Outfitter’s manual ¼-turn valves are designed for match-light systems and electronic ignition kits, offering both functionality and decorative appeal. Here’s everything you need to know about selecting, installing, and using these valves in your fire pit project.

What Are Manual On/Off Valves for Gas Fire Pits?

Manual on/off valves allow you to:

• Light the gas fire pit in a match-light system.
• Control the gas flow to the burner.
• Serve as an emergency gas shut-off for electronic ignition systems.

These valves have a CSA-approved brass cast valve, a decorative flange, and a 4-inch key. With their easy-to-use design and reliable operation, they’re essential for both safety and convenience in DIY gas fire pit setups.

 

How Manual Valves Work

The manual valve is installed inside the fire pit enclosure, while the decorative flange sits on the outside for easy access. The key is inserted through the flange to reach and operate the valve. This configuration keeps the valve concealed for a cleaner aesthetic while maintaining accessibility.

Key Length and Wall Thickness

If your fire pit enclosure wall is thicker than 4 inches, you may need a longer key to reach the valve. A custom sleeve can be made using ¾-inch standard gas pipe fittings to extend the reach.

 

Choosing the Right Valve for Your Fire Pit

Manual on/off valves come in two primary sizes and configurations:

1. Valve Sizes

• ½-inch Valve: Suitable for burners up to 24 inches, capable of flowing 150,000 BTUs.
• ¾-inch Valve: Designed for larger burners, flows up to 300,000 BTUs.

The size of your valve determines the gas flow, so it’s important to match the valve to the size of your burner for optimal performance.

2. Configurations

• Straight Configuration: Best for setups where the gas line enters and exits in a straight path.
• Angle Configuration: Ideal for situations where the gas line requires a 90-degree turn.

Both configurations flow the same amount of gas, so the choice depends on the layout of your fire pit.

Installation Tips for Manual Valves

Proper manual installation of on/off valves is critical for safety and performance. Follow these tips to ensure a successful setup:

1. Direction of Gas Flow

Each valve features an arrow indicating the direction of gas flow. Ensure that gas enters the valve on one side and exits toward your burner pan and burner on the other side.

2. Use Whistle-Free Flex Lines

Use whistle-free flex lines to connect your valve to the gas line and burner for an easy and noise-free installation. These flex lines reduce unwanted whistling sounds caused by high gas pressure.

3. Secure the Decorative Flange

Attach the decorative flange to the exterior of your fire pit enclosure. This flange provides a polished look and ensures the key can easily reach the valve for operation.

4. Test for Leaks

After installation, test your connections for leaks using a soapy water solution. Any bubbling indicates a leak that needs to be addressed before use.

Benefits of Manual On/Off Valves

Manual on/off valves offer several benefits for DIY gas fire pits:

• Safety: Easily shut off the gas in case of an emergency.
• Convenience: Simple control of gas flow and fire pit operation.
• Durability: Made with high-quality brass for long-lasting performance.
• Aesthetic Appeal: Decorative flange options enhance the overall look of your fire pit.
