Checking the Propane Gas Pressure Supply to Your Generator

Proper maintenance is crucial for keeping your equipment running smoothly and efficiently. In this article, we will focus on the importance of schedule maintenance for equipment, with a specific focus on checking the propane gas pressure supply to your generator.

Importance of Schedule Maintenance for Equipment

Performing regular maintenance on your equipment can save you money in the long run. It helps identify and address any issues before they escalate into more significant problems. One of the simplest ways to ensure the smooth operation of your equipment is to conduct schedule maintenance.

Checking Propane Gas Pressure Supply to Your Generator

To check the propane gas pressure supply to your generator, follow these steps:

1. Removing the Fuel Regulator Plug

Start by removing the 1/8 inch plug on the fuel regulator. This will provide a point to attach your manometer to.

2. Attaching the Manometer

Attach a 5/16 inch barb by 1/8 inch male iron pipe adapter to the fuel regulator. Apply a bit of pipe sealant (pipe dope) on the adapter thread and screw it in. Connect the manometer to the adapter.

3. Checking Gas Pressure at Another Location

To isolate the problem, turn off the fuel supply and disconnect the generator flex connector. Attach a 1/2 inch male iron pipe by 1/8 inch black bushing onto the gas line where the flex hose was disconnected. Connect the same adapter used for testing at the fuel regulator. Observe the pressure reading.

Identifying the Problem with Gas Pressure

By comparing the pressure readings between the supply on the black iron pipe and the regulator in the generator, you can identify where the problem lies. If the pressure is consistent, the issue may lie elsewhere. In this case, reinsert the fuel regulator plug.

Reinstalling the Fuel Regulator Plug

Apply a little pipe dope on the plug and use a hex bit to start the plug by hand. Finish tightening it with a ratchet, being careful not to over tighten.

Installing a Tee and Reconnecting the Manometer

To further diagnose the issue, install a 1/2 inch tee and put the adapter back in for the manometer on the branch. Apply pipe dope to the flexible hose adapter, ensuring no sealant gets on the inside of the fitting. Connect the manometer and observe the pressure.

Contacting the Propane Company for Assistance

If the gas pressure issue persists, it is advisable to contact the propane company and have them inspect their equipment. They can help determine if the primary regulator at the propane tanks is causing the problem.

Resolving the Gas Pressure Issue

Once the propane company addresses the issue, the gas pressure should stabilize. Generac recommends a gas pressure between 10 and 12 inches water column for propane. However, a slightly higher pressure of around 15 to 16 inches water column may also be acceptable.

Recommended Propane Gas Pressure for Generac Generators

Generac recommends a gas pressure between 10 and 12 inches water column for propane to ensure optimal performance of their generators.

Testing for Gas Leaks

While performing the maintenance procedures, it is essential to check for gas leaks. Loosen the cap on the black iron pipe elbow to create a leak and observe how the bubbles react. Tighten the cap, reapply soap, and double-check for any leaks.

Final Steps to Secure Fittings

After running the generator without any issues, remove the test fittings and restore the original setup. Apply pipe dope to the adapter that connects the black iron pipe elbow to the flexible generator connector. Ensure there is no debris inside the fittings and use lubricant if needed. Tighten the fittings, being careful not to over-tighten and damage them.

Conclusion

Regular maintenance is vital for the smooth operation of equipment, and checking the propane gas pressure supply is an essential part of that. By following the steps outlined in this article, you can identify and address any gas pressure issues with your generator. Remember to contact the propane company if necessary and always prioritize safety when working with gas equipment.

FAQ

Q: Why is checking the gas pressure supply important for generators?

A: Checking the gas pressure supply ensures that the generator receives the correct amount of fuel for optimal performance and prevents potential issues caused by low or inconsistent pressure.

Q: What should I do if the gas pressure readings are not within the recommended range?

A: If the gas pressure readings are outside the recommended range, it is advisable to contact the propane company for assistance as the issue may lie with the primary regulator at the propane tanks.

Q: Are slightly higher gas pressure readings acceptable for Generac generators?

A: While Generac recommends a gas pressure between 10 and 12 inches water column for propane, slightly higher pressure readings of around 15 to 16 inches water column may still provide acceptable performance.

Q: How can I ensure the fittings are secure after testing for gas leaks?

A: After confirming there are no leaks, tighten the fittings carefully, ensuring not to over-tighten and cause damage. Apply pipe dope and lubricant if needed.

Q: Can I perform these maintenance procedures on my own?

A: It is advisable to have some technical knowledge or seek professional assistance when working with gas equipment. Prioritize safety and follow all guidelines and regulations.
