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 authorized references to the examination center.

The examination provides 90 minutes for 40 questions. That allows slightly more than two minutes per question. Candidates who are unfamiliar with the references may spend too much time searching and leave insufficient time for pipe sizing, code interpretation, or detailed equipment questions.

Reference materials 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 for fuel-gas sizing and other trade calculations.

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

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

Use the International Residential Code for mechanical and fuel-gas requirements involving one- and two-family dwellings. Important areas include appliance locations, combustion air, residential fuel piping, equipment clearances, venting, and installation requirements.

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

Use NFPA 31 for oil-burning appliances, storage tanks, oil piping, burners, controls, combustion air, venting, installation, and operation. Become familiar with the organization of the standard and the location of equipment-specific requirements.

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

Develop a consistent reference-search process. Identify the primary subject in the question, choose the most relevant code or standard, use the index or table of contents, and review the complete applicable provision. Read definitions, exceptions, table headings, notes, and cross-references before selecting an answer.

State Requirements

The Connecticut B-2 Limited Gas and Oil Burner Journeyperson license authorizes qualifying gas and oil burner work within the limits established for the classification.

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 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 limits.

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

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

Applicants using an equivalent-experience or out-of-state pathway must provide sufficient documentation for Connecticut to evaluate their classroom training, on-the-job experience, employment history, and prior credentials.

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

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

A B-2 journeyperson license is separate from a contractor license and business registration. A journeyperson who plans to operate a contracting business or assume contractor-level responsibility may need an appropriate contractor credential and additional business registrations.
