CSD-1 Boiler Testing
No More Guesswork—CSD-1 Inspections with Clear Results and Real Compliance.
Michigan law requires annual boiler inspections—but that doesn’t mean you need to figure it out alone. We handle everything so you can stay focused on what matters.

Don’t Let a Missed Inspection Put Your Facility at Risk
If your facility runs an automatically fired boiler, CSD-1 testing is not optional. It’s required by state code—and skipping it could mean shutdowns, citations, or worse. We help you avoid all of it.
Our licensed technicians test every safety device to ASME CSD-1 standards and provide documented results that satisfy state inspectors. No confusion, no red tape, no callbacks.
What We Test During a CSD-1 Inspection
Real safety. Real compliance. Real documentation.
Simulated fault testing confirms proper burner shutdown in low-water scenarios. We also inspect for corrosion, mechanical failure, and verify reset functionality per manufacturer requirements.
We ensure they lift and reseat properly, with matched ratings and safe operation. We inspect tag data, physical condition, and confirm discharge piping is clear and properly routed.
We test safety interlocks, flame sensors, startup sequences, and high-limit shutdowns. These tests ensure your boiler won’t operate under unsafe conditions and complies with ASME CSD-1 startup logic.
We verify all wall-mounted and remote emergency stop switches respond instantly. This includes checking wiring integrity, control integration, and labeling per Michigan boiler code.
From limit controls to ignition lockouts—we test and document any additional safety components your system includes. We adapt to your boiler’s specific configuration to ensure no device is overlooked.
Signed documentation with setpoints, models, and methods—everything you need to stay compliant. We deliver a clear, inspector-ready report that satisfies both Michigan Boiler Rules and ASME standards.
