What is ASME CSD-1 boiler testing in Michigan?
ASME CSD-1 boiler testing in Michigan refers to the inspection and testing of safety controls on automatically fired boilers, as required by state law. According to Rule 27 of the Michigan Boiler Rules, all safety devices—such as pressure relief valves, low-water cutoffs, and flame safeguards—must be tested by a licensed mechanical contractor. Testing must follow the standards outlined in ASME CSD-1 (2018) and be documented with model numbers, setpoints, and test results (see CSD-1 Rule FAQ, p. 3). These requirements apply to most commercial and institutional boilers, and failing to comply may result in penalties or a shortened inspection cycle.
What is involved in a boiler inspection?
A boiler inspection under Michigan’s CSD-1 requirements involves testing and verifying the function of all safety controls and devices including pressure relief valves, low-water cutoffs, burner management systems, high-limit controls, and emergency shutdown switches. The inspection includes both operational checks and formal documentation of each tested device’s model, set point, and test result. These inspections must follow ASME CSD-1 (2018) and manufacturer guidelines.
What systems require a boiler inspection?
All automatically fired boilers in Michigan must comply with CSD-1, regardless of input rating, including those used in churches, schools, and factories. This includes small boilers (under 400,000 BTU/hr) as long as they start automatically. Boilers ≥12,500,000 BTU/hr are excluded and fall under NFPA 85 instead.
How much does a boiler inspection cost?
The Michigan Boiler Rules list state inspection fees (see table below), which range from $75 for low-pressure boilers to higher fees for special inspections. However, costs for CSD-1 testing by licensed contractors are market-based and vary. Typical service provider rates for CSD-1 testing may range from $300 to $800+ depending on system size and travel, though these are not published in the code and vary by provider.

How often is a boiler inspection required?
A licensed mechanical contractor must test all safety controls at least once per inspection cycle, which must occur within 12 months of the state certificate inspection. For small boilers (≤400,000 BTU/hr), professional testing is only required once per cycle, but operator checks (daily, weekly, monthly) must still be performed.
Who is qualified to perform a CSD-1 inspection?
Only licensed mechanical contractors with the proper classification can perform CSD-1 safety control testing. While facility staff may conduct routine checks, the annual inspection and documentation must be completed under the contractor’s supervision.
How do I find qualified boiler inspection companies near me?
To locate qualified contractors, search for Michigan-licensed mechanical contractors with boiler classifications using LARA’s license lookup tool or consult with local HVAC service providers that advertise commercial boiler service. Be sure to verify they have experience with ASME CSD-1 inspections and provide formal service documentation for compliance.
