How To: Testing High Gas Pressure Safety
Learn how to test the High Gas Pressure Safety on a steam boiler. In this video, we walk through the procedure for testing the safety device and verifying that it responds properly to an excessive gas pressure condition.
The high gas pressure safety is a critical component of the boiler’s fuel train. Proper testing confirms that the device is correctly set and will interrupt burner operation if gas pressure exceeds the specified limit.
Topics covered include:
- Identifying the high gas pressure safety on the boiler gas train
- Understanding its purpose and pressure setting
- Preparing the boiler and controls for testing
- Adjusting the safety to initiate the test condition
- Verifying response at the specified pressure
- Confirming proper boiler shutdown or burner lockout
- Resetting the safety after testing
- Returning the device to its proper operating setting
- Verifying normal boiler operation
Whether you’re a service technician, commissioning technician, facility maintenance professional, or boiler operator, this guide provides a practical overview of high gas pressure safety testing as part of steam boiler commissioning and maintenance.
High gas pressure safety testing should only be performed by qualified personnel familiar with the boiler, gas train, and applicable safety requirements. Always follow the appropriate Fulton installation, operation, and service documentation, gas train manufacturer instructions, and applicable codes and regulations. Verify the correct pressure settings for the specific boiler before making adjustments.
