I'm under the impression in Connecticut that if the boiler operates under 300 psi no license is required but take it with a grain of salt. Inspections and licensing are a good thing with regard to boilers. I've talked to people in the navy who where on a ship that had a boiler problem. About 8 people died and many more badly burned. High pressure steam is serious business.
Anything over 15# is high pressure steam in CT. The Connecticut Department of Public Saftey (State Police) are the authority that license the operation of any commercial applications. The boiler must be inspected twice yearly, one is an internal (wet and firesides) and the other is a walkaround. The inspections are done by the insurance company, in my case it is Factory Mutual.
