Natural gas trains are critical to the daily operations of burners and boilers for many facilities. The maintenance, cleaning, and repair of this equipment are essential for employee safety, efficiency, and profitability. Any facility with major heating components like production facilities, schools, hospitals, and industrial, manufacturing, and food production plants with boilers and burners should be conducting at least an annual maintenance/safety inspection.

Through a series of safety and control devices, gas trains ensure safe and efficient combustion for your facilities’ burners and boilers.  A properly operating gas train will achieve this through modulating gas flow to the burner for appropriate combustion and utilizing components to safely shut the burner down should a failure occur.

Understanding the importance of routine inspections and maintenance for gas trains is necessary to prevent potential explosions, injuries, and property damage.


Gas trains require regular inspection and maintenance by highly trained, experienced professionals. Annual testing and preventative maintenance are often a requirement of insurance agencies, equipment manufacturers, and even national standards, including ANSI, ASME, NFPA, and NEC. According to the National Board of Boiler and Pressure Vessel Inspectors, 83% of boiler accidents are due to human error or lack of knowledge.

It is important to schedule and perform gas train inspections for several reasons:

  • Reliability of equipment
  • Lack of downtime
  • Insurance compliance
  • Gas savings
  • Safety of your people and facilities

“When you’re running production, you need to plan maintenance for your equipment, otherwise your equipment will plan the maintenance for you when you least expect it,” said Nick Hietpas, Regional HVAC Operations Manager.

By not maintaining your equipment, there’s a higher probability of failure. Incorrectly vented valves, relief devices, regulators, and pressure switches can fail to properly respond upon use or not react at all. Control valves and linkages may loosen with cycling, or debris can accumulate in fans, burners, and air piping, which alters air-to-fuel ratios and reduces energy efficiency.


When Bassett Mechanical inspects your facility’s natural gas train, we will do regular maintenance along with inspection and testing on all parts of the system.  You will also receive documentation, which may be required for your insurance or auditing process. Managers can also use the documentation to compare the equipment’s condition with that of previous inspections.

When you’re running production, you need to plan maintenance for your equipment, otherwise your equipment will plan the maintenance for you when you least expect it.

We inspect safety interlocks, safety shut-off valves (SSOV), low and high gas pressure switches, fuel regulators, flame color and shape, strainers, burners, burner management systems (BMS), gauges, and monitoring devices. Upon completion of the inspection, the customer will receive a comprehensive checklist that details the pass/fail readings of all the components. If there are components that failed, our experts will provide recommendations and solutions to help ensure the equipment is functioning properly with limited disruption.

Your biggest defense and vital part of staying safe is investing in a comprehensive preventative maintenance program. Investing in a preventative maintenance agreement with a service provider is an important decision and can make a significant impact on the future of your equipment. Preventative maintenance will help with system reliability, extend the life of your equipment, provide energy efficiencies, and protect your investment.


We understand the importance of ensuring the optimal performance of your system and facility. Our gas train inspections can be completed by our highly trained service technicians with extensive industry experience.

After the inspection, you’ll receive documentation that your equipment is working efficiently and properly, documentation that complies with insurance companies, and most importantly, you’ll have peace of mind that your most important asset, your people, are safe.

Failure to inspect and maintain gas trains in proper working order could result in equipment downtime and dangerous conditions for your people and facility. Don’t wait for a near-miss to get your inspection scheduled. Call our experts today!
