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 examination center.

The two-hour testing period provides an average of approximately two minutes and twenty-four seconds per question. Candidates who are unfamiliar with the books may spend too much time searching, leaving insufficient time for pipe-sizing problems, code interpretation, and more detailed equipment questions.

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 references during the examination. Loose papers and unauthorized attached materials are not permitted. Questions and answers written into the books must be removed before entering the testing room.

A silent, nonprinting, non-programmable calculator may be used during the examination. Candidates should practice using an approved calculator while working through fuel-gas sizing and other trade calculations.

For gas-pipe sizing questions, candidates must use the longest-length method. Preparation should include identifying the total connected appliance load, determining the longest developed length, selecting the correct pressure and pipe-material table, and choosing a pipe size that provides sufficient capacity.

Use the International Mechanical Code for mechanical equipment, combustion air, appliance installation, chimneys, vents, fuel systems, clearances, access, and safety requirements.

Use the International Residential Code for mechanical and fuel-gas requirements that apply to one- and two-family dwellings. Review residential appliance installations, fuel piping, combustion-air provisions, venting rules, and equipment-location requirements.

Use the International Fuel Gas Code for fuel-gas piping, regulators, appliance connections, testing, purging, combustion air, venting, and gas-utilization equipment. This code is particularly important for general fuel-gas system questions.

Use NFPA 31 for oil-burning equipment, storage tanks, oil piping, burners, controls, combustion air, venting, installation, and operation. Candidates should become familiar with the organization of the standard and its equipment-specific provisions.

Use NFPA 54 for natural-gas piping, longest-length sizing, appliance installation, pressure regulation, combustion air, testing, purging, and venting. Use NFPA 58 for LP-gas containers, piping, regulators, equipment, separation distances, storage, and handling.

Develop a repeatable reference-search process. Identify the main subject in the question, choose the most relevant book, use the index or table of contents, and read the complete applicable section. Review definitions, exceptions, table headings, notes, and cross-references before selecting an answer.

State Requirements

The Connecticut B-1 Limited Gas and Oil Burner Contractor license authorizes qualifying gas and oil burner work within the limits established for the classification.

The license covers the installation, repair, replacement, alteration, and maintenance of gas or oil burners for domestic and light commercial applications.

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 permitted scope includes 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 B-1 license limits.

The classification includes sheet-metal work when that work is related to the authorized B-1 scope. The license does not provide unlimited authority for mechanical, plumbing, heating, cooling, or fuel work outside the defined classification.

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

Applicants using equivalent training, experience, or an out-of-state credential must provide sufficient records for Connecticut to evaluate their qualifications. Previous employment or licensing in another jurisdiction does not automatically establish eligibility.

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

After passing the required trade and Business and Law examinations, the applicant must complete the remaining licensing steps and submit the applicable state charges. A passing examination result alone does not authorize contracting work.

The individual B-1 professional license is separate from business registration, tax accounts, insurance, permits, and other company-level operating requirements.
