Q: I got a violation letter that said something like No documented evidence of triennial (or annual) testing and operational checks of controls and safety devices that were to be conducted by a licensed mechanical contractor. Per Rule 339.5206 and ASME CSD-1. What do I do?

A: You need to have your boiler serviced by a qualified Mechanical Contractor. A Mechanical Contractor who is qualified to conduct boiler service has a license that includes a limited or unlimited heating service work classification.

Q: How often should my boiler be serviced?

A: High- and low-pressure steam boilers and larger hot water heating and hot water supply boilers need to be serviced once per year. Hot water heating and hot water supply boilers under 400,000 btu/hr input should be serviced once every three years, within 12 months of the expiration date printed on the Certificate of Inspection. Some water heaters are not required to have CSD-1 maintenance.

Q: How do I locate a qualified Mechanical Contractor

A: You can find a contractor on the BCC website following these directions Go to www.michigan.gov/bcc In the top bar click "Verify a License" Click "Construction/Skilled Trades" Scroll down to "Search for a License" Go to the "License Type" drop down box and select "Mechanical Contractor" Go to the bottom of the page and click "Search" This will list all mechanical contractors licensed in Michigan Click on the business name (in blue) and the license status and license classifications will be Shown

Q: My boiler has been serviced; now what?

A: The service technician will leave a copy of the service report in the boiler room or if they give it to you, you should post it in the boiler room because the boiler inspector will be looking for it during the inspection. If you received a violation for “No documented evidence….”, you may call the Inspector, their name and number will be at the bottom of the violation letter, or you can scan and e-mail the filled out “CERTIFICATE OF COMPLIANCE” or the service report to our office at bccblr@michigan.gov .
