What This License Authorizes
B-1 license holders may perform, supervise, and contract for installation, service, and repair of gas-fired and oil-fired heating equipment in domestic and light commercial settings. This includes furnaces, boilers, water heaters, and related gas/oil burner components within the 5 gallons-per-hour consumption limit.
Examination and Experience Requirements
Applicants must pass both the Connecticut Business and Law Exam and a Trade-Specific Gas and Oil Burner Exam. Applicants must have relevant experience in burner installation and service, typically through apprenticeship and journeyperson experience.

Consequences of Operating Without a License
