Open Book Test

The Connecticut Limited Gas and Oil Burner Journeyperson (B-2) trade examination is an open-book test. Candidates are responsible for bringing their own approved references to the examination center.

The examination provides 90 minutes for 40 questions. That leaves slightly more than two minutes per question. Candidates who are unfamiliar with their references may lose valuable time deciding where to search or moving between several codes for one problem.

Reference books may be highlighted, underlined, annotated, or indexed before the examination. Permanent tabs may be used to mark important chapters, tables, definitions, and frequently referenced provisions. Temporary or repositionable tabs are not permitted.

Candidates may not write in the books during the examination. Loose papers and unauthorized attached materials are not allowed. Questions and answers written into the references 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 when completing fuel-gas sizing exercises and other trade calculations.

For gas-pipe sizing questions, candidates must use the longest-length method. This method generally requires the candidate to identify the longest developed piping length in the system and use that length when selecting pipe sizes for the connected appliance loads.

Practice identifying the correct fuel, operating pressure, pipe material, developed length, and appliance demand before selecting a sizing table. Always read table headings, notes, limitations, and related provisions before choosing an answer.

Use the International Mechanical Code, 2021 for mechanical equipment, appliance installation, combustion air, fuel systems, chimneys, vents, clearances, service access, and general mechanical safety requirements.

Use the International Residential Code for One- and Two-Family Dwellings, 2021 for mechanical and fuel-gas requirements that apply to qualifying residential construction. Important topics include appliance locations, equipment clearances, combustion air, fuel piping, venting, and residential installation requirements.

Use the International Fuel Gas Code, 2021 for gas-piping systems, pressure regulators, appliance connections, testing, purging, combustion air, venting, gas-utilization equipment, and fuel-gas safety.

Use NFPA 31 for questions involving oil-burning appliances, fuel tanks, oil piping, burners, controls, combustion air, venting, installation, and operation. Candidates should become familiar with the standard’s definitions, equipment requirements, tables, and safety provisions.

Use the NFPA 54 National Fuel Gas Code Handbook for natural-gas piping, appliance installation, pressure regulation, combustion air, testing, purging, venting, and longest-length sizing guidance.

Use NFPA 58 for LP-gas containers, regulators, piping, equipment, storage, handling, separation distances, testing, installation, and safety.

Develop a consistent search method before test day. 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 notes, figures, and cross-references before selecting an answer.

State Requirements

The Connecticut B-2 Limited Gas and Oil Burner Journeyperson license authorizes qualifying burner and fuel-system work within the limitations established for the credential.

The 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 permitted scope includes piping for petroleum-based and alternative fuels, including tanks and related equipment. It also includes LP gas supplied by containers, natural-gas piping, approved gas applications, gas-utilization equipment, and related accessories within the B-2 limitations.

The B-2 classification includes sheet-metal work when that work pertains to the limited scope of the credential. The license does not provide unrestricted authority for plumbing, cooling, heating, mechanical, or fuel work outside the B-2 classification.

Applicants must complete a registered apprenticeship program or demonstrate equivalent experience and training accepted by the Connecticut Department of Consumer Protection.

Applicants relying on equivalent experience, training, or an out-of-state credential must provide sufficient documentation for Connecticut to evaluate their qualifications. Previous employment or licensing elsewhere does not automatically establish eligibility.

PSI administers the examination but does not determine whether an applicant qualifies for the B-2 license. The Department of Consumer Protection reviews the application and authorizes eligible candidates to test.

After passing the examination, the applicant must complete any remaining licensing requirements and submit the applicable state charges. A passing examination score alone does not authorize regulated work.

A B-2 journeyperson license is separate from a contractor license and business registration. A journeyperson who plans to operate a business, contract directly with customers, or assume contractor-level responsibility may need an appropriate contractor license and other business credentials.
