CSD-1 Testing for State of Michigan Boiler Compliance

If you own a business in the state of Michigan, then it’s important that you’re aware of CSD-1 testing. CSD-1 testing, which stands for controls and safety devices testing, is a guideline that has become code in various states, including Michigan. These special guidelines cover the requirements for assembling, installing, servicing, and operating the control and safety devices of automatically operated boilers. These guidelines apply to any automatic boiler that’s directly fired with oil, gas, gas and oil, or electricity, provided that the fuel input rating is below 12,500,000 BTU per hour. So, if your company in Michigan utilizes a boiler that meets these requirements, you should make an effort to learn about and understand the CSD-1 testing guidelines.

Required Maintenance and Test Schedules

According to the CSD-1 testing guidelines, any automatically fired boilers used in commercial or industrial settings must be kept on maintenance and test schedules for proper CSD-1 testing. If you’re a business owner with one or more of these boilers in your facility, it’s up to you to ensure that this happens. Specifically, the guidelines require that the controls and safety devices of the boiler be tested by someone who possesses a mechanical contractor license and has the necessary classification. This ensures that the individual handling the testing is qualified and knowledgeable enough to do it properly. In addition to testing the boiler’s controls and safety devices, that contractor must document them, create a copy of the document, and post it near the appliance.

Safety Check Specifics

The specifics of how CSD-1 testing is conducted vary depending on the model of boiler, but there are certain components that must be checked on all qualifying boilers. These include the gas valve, pressure relief valve, operating controller, and high pressure or temperature limit. Some boiler models may require additional components to be included in the safety check procedure. Listed below are some of the common boiler components and systems that need to be tested.

  • Indicating lights
  • Main low water cut off
  • Low fire hold
  • Water and steam leaks
  • Combustion air proving
  • Pilot flame turn-down

Why Is CSD-1 Testing Important?

CSD-1 testing is important because it ensures that your boiler is operating safely and efficiently. The CSD-1 (Controls and Safety Devices) standard is a set of guidelines and requirements established by the American Society of Mechanical Engineers (ASME) for the design, installation, and maintenance of controls and safety devices on boilers. It is meant to reduce the risk of boiler-related accidents and improve energy efficiency. Some states or municipalities require that boilers undergo CSD-1 testing as part of their regular maintenance. Even if it is not required by law, it is generally a good idea to have your boiler tested to ensure that it is operating safely and efficiently.

CSD-1 testing helps ensure that the controls and safety devices on your boiler are functioning properly and in compliance with safety standards. This can help reduce the risk of boiler-related accidents, such as explosions or fires.
During a CSD-1 test, technicians will examine the controls and safety devices on your boiler to see if any adjustments or repairs are necessary. This can help improve the efficiency of the system, which can save you money on energy costs in the long run.
In some states or municipalities, CSD-1 testing is required as part of regular boiler maintenance. By having your boiler tested, you can ensure that it is in compliance with local regulations and avoid any fines or legal issues.
