Open Book Test

The Connecticut Limited Gas and Oil Burner Contractor (B-1) trade examination is an open-book test. Candidates are responsible for bringing their own approved references to the testing center.

The two-hour time limit provides an average of approximately two minutes and twenty-four seconds per question. Candidates who are unfamiliar with the books may lose valuable time deciding where to search. Preparation should include repeated practice with each reference under timed conditions.

Reference books may be highlighted, underlined, annotated, or indexed before the examination. Permanent tabs are permitted. Temporary tabs, including removable or repositionable notes, are not allowed.

Candidates may not write in the books during the examination. Loose papers and unauthorized attached materials are prohibited. Questions and answers written into the references must be removed before entering the examination room.

A silent, nonprinting, non-programmable calculator may be used. Candidates should practice using an approved calculator for gas-pipe sizing and other trade calculations.

The International Mechanical Code supports questions involving mechanical equipment, appliance installation, combustion air, chimneys, vents, fuel systems, clearances, access, and safety. The International Residential Code addresses residential mechanical and fuel-gas requirements for one- and two-family dwellings.

The International Fuel Gas Code supports preparation involving gas-piping systems, appliance connections, pressure regulators, combustion air, venting, testing, purging, and fuel-gas equipment. NFPA 54 provides additional natural-gas requirements and detailed guidance for gas installations.

NFPA 31 covers oil-burning equipment, tanks, fuel piping, burners, controls, combustion air, venting, and related installation requirements. NFPA 58 covers liquefied petroleum gas containers, regulators, piping, equipment, separation distances, installation, operation, storage, and safety.

For gas-pipe sizing questions, candidates must use the longest-length method. Practice identifying the total connected load, measuring the longest developed piping length, choosing the correct pressure and material table, and selecting a pipe size with sufficient capacity.

Develop a consistent reference-search method. Identify the principal subject, select the most relevant code or standard, use the index or table of contents, and read the complete applicable provision. Review definitions, exceptions, table headings, notes, and related sections before selecting an answer.

Licensing Steps

The Connecticut Department of Consumer Protection regulates occupational trade licenses and determines examination eligibility. PSI administers the examination after the state approves the applicant.

1. Confirm the B-1 classification. Review the license scope and determine whether it covers the gas and oil burner work you intend to perform or supervise.
2. Meet the contractor qualification requirement. Applicants must document two years as a properly licensed journeyperson or equivalent experience and training accepted by Connecticut.
3. Complete the state application. Submit the occupational contractor application and all requested personal, employment, licensing, and qualification information.
4. Provide supporting documentation. Submit employment records, prior license information, training documents, education records, or equivalent-experience evidence required by the state.
5. Obtain third-party verification. Employers, supervisors, training providers, or licensing authorities may need to verify the applicant’s qualifications.
6. Receive approval to test. Connecticut must determine that the applicant satisfies the eligibility requirements before examination registration.
7. Register with PSI. After approval, create or access the testing account, pay the applicable charges, and schedule the required examination portions.
8. Prepare for the B-1 trade examination. Review the content outline and practice navigating the authorized references.
9. Prepare for the Business and Law examination. Connecticut requires contractor applicants to pass both a trade examination and a Business and Law examination.
10. Take the required examinations. Bring acceptable identification, approved references, and a permitted calculator while following testing-center rules.
11. Complete the licensing process. Submit passing examination results, licensing charges, and any remaining documentation required by Connecticut.

The B-1 trade examination and the contractor Business and Law examination are separate requirements. Passing the trade test does not replace the Business and Law examination.

This exam book package does not include the Business and Law reference, Application Service, application preparation, examination registration, government charges, or submission of licensing documents.

State Requirements

The Connecticut B-1 Limited Gas and Oil Burner Contractor license permits the installation, repair, replacement, alteration, and maintenance of gas or oil burners for domestic and light commercial installations.

For this classification, a domestic or light commercial burner is one consuming five gallons of fuel or less per hour or serving a system with a total heating load not exceeding 500,000 BTUs.

The license permits piping for petroleum-based fuels and alternative fuels, including tanks and related equipment. It also includes liquefied petroleum gas supplied by containers, natural-gas piping, approved gas applications, gas-utilization equipment, and accessories within the license scope.

The B-1 classification includes sheet-metal work when that work pertains to the limitations of the credential. The license does not create unlimited authority for mechanical, heating, cooling, plumbing, or fuel work outside the defined B-1 scope.

Applicants must document two years as a properly licensed journeyperson or demonstrate equivalent experience and training accepted by the Connecticut Department of Consumer Protection.

Applicants relying on equivalent training, experience, or an out-of-state credential must provide sufficient documentation for the state to compare their qualifications with Connecticut requirements. Prior employment or licensing in another jurisdiction does not automatically establish eligibility.

PSI administers the examinations but does not decide whether an applicant qualifies for the license. The Department of Consumer Protection reviews the application and authorizes eligible candidates to test.

After passing the trade and Business and Law examinations, the applicant must complete the remaining licensing requirements and submit the applicable state charges. Passing the examinations alone does not authorize contracting work.

The individual B-1 license is separate from business registration, tax accounts, insurance, permits, and other company-level requirements. Additional registrations may apply depending on the business structure and services offered.
