- The gas supply to your home MUST be shut off at the main shut-off valve. This should only be done by a professional.
- Tapping into the Gas Line:
- The professional will install a T-fitting into the existing gas line.
- A shut-off valve is installed on the new branch for the BBQ line.
- Running the Gas Line to the BBQ:
- A gas-rated pipe is run from the T-fitting to the BBQ location. This may involve trenching if the BBQ is located away from the house.
- The pipe is buried according to local code requirements.
- Connecting the BBQ:
- The gas line is connected to a quick-connect fitting on the BBQ’s natural gas conversion kit.
- Leak Testing:
- A leak test is performed on all connections using a soap and water solution. Bubbles indicate a leak, which must be addressed immediately.
- Converting the BBQ:
- The BBQ itself needs to be converted to run on natural gas. This typically involves changing the orifices (the small brass nozzles that control the gas flow) to smaller sizes to accommodate the higher pressure of natural gas compared to propane. The instructions specific to your BBQ model will provide detailed conversion procedures.
- Pressure Testing:
- A professional should conduct a pressure test on the entire system to ensure it meets code requirements.
- Inspection:
- Schedule an inspection with your local municipality to ensure the installation meets all applicable codes.
Essential Components for a Natural Gas BBQ Connection
The following components are typically required for a natural gas BBQ connection. These components should be installed by a qualified professional.
- T-fitting: Connects the new gas line to the existing line.
- Shut-off Valve: Allows for easy shut-off of the gas supply to the BBQ.
- Gas-Rated Pipe: Carries the natural gas from the main line to the BBQ. (Typically black iron or polyethylene.)
- Quick-Connect Fitting: Enables easy connection and disconnection of the BBQ.
- Natural Gas Conversion Kit: Adapts the BBQ to run on natural gas. This kit contains specialized orifices and, sometimes, a new regulator.
- Leak Detection Solution: Used to check for gas leaks at all connections.
Common Mistakes to Avoid (and Why Professional Installation is Key)
Several mistakes can occur during a natural gas BBQ connection, highlighting the importance of professional installation.
- Improper Piping: Using incorrect pipe materials or joining techniques can lead to leaks. Always use gas-rated piping installed by a professional.
- Inadequate Leak Testing: Failing to thoroughly test for leaks can create a serious safety hazard. A professional uses specialized equipment and experience to ensure no leaks exist.
- Incorrect BBQ Conversion: Using the wrong orifices or failing to adjust the regulator properly can result in inefficient combustion or dangerous flare-ups. Conversion kits need to be installed correctly and pressure tested by a professional.
- Bypassing Permits: Ignoring local permitting requirements can lead to fines and potential safety hazards. Professionals are familiar with local codes and permitting processes.
- Ignoring Depth Requirements: If the gas line requires trenching, ignoring the minimum depth requirement leads to future damage. A professional would know the legal requirements.
- Incorrectly estimating PSI: Homes have different requirements and BBQ’s have different requirements for gas pressure. A professional would understand the pressure needs.
Frequently Asked Questions (FAQs)
1. Can I connect my propane BBQ directly to a natural gas line?
No, you cannot directly connect a propane BBQ to a natural gas line. Propane and natural gas operate at different pressures and require different orifice sizes. Connecting a propane BBQ to natural gas without conversion is dangerous and could lead to a fire or explosion. A natural gas conversion kit is necessary.
2. How do I know if my BBQ is convertible to natural gas?
Check your BBQ’s owner’s manual or the manufacturer’s website. Many BBQs can be converted, and manufacturers often sell conversion kits. If there is no available kit, then you cannot convert your BBQ because you’d be taking on a serious fire hazard.
3. What tools are required for a natural gas BBQ connection?
The tools required include pipe wrenches, pipe thread sealant, a level, a leak detection solution, and potentially trenching tools if burying the gas line. Again, this should be done by a professional using proper equipment.
4. How deep does a natural gas line need to be buried?
The burial depth depends on local codes, but generally, a natural gas line must be buried at least 12 inches deep. Check local regulations for specific requirements.
5. What type of pipe should I use for a natural gas line?
Generally, black iron or polyethylene (PE) pipe is used for underground natural gas lines. Consult local codes and a qualified professional for the specific requirements in your area.
6. How do I test for leaks after connecting the BBQ?
Apply a solution of soapy water to all connections. If bubbles form, there is a leak. Immediately shut off the gas supply and contact a professional to repair the leak.
7. What is a BTU and why is it important?
BTU stands for British Thermal Unit, a measure of heat output. It’s important to match the BTU rating of your BBQ to the capacity of your natural gas line. Overloading the gas line can lead to insufficient gas pressure.
