Prepare for the Mississippi Boiler Installation and Repair Contractor examination with a complete six-book reference package and organized application support. This package combines the technical books identified for the trade exam with an Application Accelerator designed to help contractors and qualifying parties approach the Mississippi licensing process in a clear, structured way.
The Boiler Installation and Repair classification covers boilers and associated gas and steam piping used in residential, commercial, and industrial applications. Candidates may encounter questions involving boiler operation, hydronic heating, fuel-gas systems, mechanical code requirements, pumps, valves, controls, piping, traps, safety, fuels, and related system components.
Because the examination covers several technical areas, candidates must know more than basic boiler terminology. They should understand operating principles, recognize system components, interpret code requirements, work with pumps and controls, and locate information efficiently within multiple references during an open-book examination.
The included books address steam plant operation, residential and light-commercial hydronic heating, mechanical systems, fuel-gas installations, federal construction safety requirements, and HVAC pump applications. Together, these references provide a broad technical foundation for preparing for the Mississippi Boiler Installation and Repair trade exam.
The Application Accelerator supports the administrative side of the licensing process. It helps candidates organize the steps associated with submitting a Mississippi contractor application, identifying the qualifying party, preparing supporting documents, receiving examination authorization, and completing the licensing process after testing.
This package is intended for experienced boiler installers, mechanical contractors, technicians, qualifying parties, business owners, and trade professionals preparing to pursue the Mississippi Boiler Installation and Repair specialty classification. It does not replace field experience, technical training, manufacturer instructions, or the candidate’s responsibility to meet all state licensing requirements.
The Application Accelerator provides preparation support for the licensing process but does not guarantee application acceptance, examination eligibility, license issuance, or approval by the Mississippi State Board of Contractors. Applicants remain responsible for submitting accurate information and satisfying all applicable requirements.
The Mississippi Boiler Installation and Repair examination is administered through PSI as part of the contractor licensing process overseen by the Mississippi State Board of Contractors. Applicants must submit the appropriate contractor application and receive testing eligibility before scheduling the trade exam.
The Boiler Installation and Repair examination contains 50 questions. Candidates are allowed 2 hours to complete the test and must earn a minimum score of 70 percent to pass.
The examination content is divided among the following subject areas:
Boilers represent the largest portion of the exam. Candidates should be prepared to review boiler types, operating principles, combustion, steam and hot-water systems, accessories, water treatment concepts, system efficiency, controls, inspection considerations, and common operating conditions.
Valves, controls, piping, and traps also account for a significant portion of the examination. Preparation should include pressure and temperature controls, safety devices, control sequences, valve applications, steam traps, piping arrangements, expansion, circulation, and system operation.
Pump questions may address pump types, performance, selection, system resistance, flow, head, efficiency, operation, and troubleshooting. The HVAC Pump Handbook supports focused review of pumping systems used in heating and mechanical applications.
Safety questions may draw from federal construction regulations and general boiler-industry practices. Candidates should understand jobsite safety, personal protective equipment, fall protection, electrical hazards, material handling, welding and cutting precautions, excavation requirements when applicable, and safe equipment procedures.
The Mississippi Boiler Installation and Repair examination is an open-book test. Candidates are responsible for bringing their permitted references to the testing center and ensuring that the books comply with PSI’s current examination rules.
Reference materials may be highlighted, underlined, and indexed before the examination. Permanent tabs may be used to identify major chapters, code sections, tables, and technical subjects. Temporary tabs, removable notes, loose papers, Post-it-style markers, and additional attached pages are not permitted.
Candidates may not write in their references during the testing session. Books should be prepared before arriving at the examination center. The name and edition of each code book should match the edition identified for the exam because code questions are based on the specifically listed code editions.
An open-book examination still requires careful study. Six references can contain thousands of pages of technical information. A candidate who does not know which book applies to a question may spend too much time searching through unrelated material.
Effective preparation includes reviewing each reference’s table of contents, index, chapter structure, definitions, diagrams, formulas, tables, and appendices. Candidates should practice identifying the primary subject of a question and selecting the most likely reference before beginning a search.
For example, a question about steam generation or boiler operation may be addressed in Steam Plant Operation. A question about residential hydronic distribution may require Modern Hydronic Heating. Fuel-gas installation questions may involve the International Fuel Gas Code, while pump-performance questions may direct the candidate to the HVAC Pump Handbook.
The Mississippi contractor licensing process begins with an application to the Mississippi State Board of Contractors. Candidates cannot schedule the Boiler Installation and Repair examination until the Board reviews the application and sends the qualifying party’s testing eligibility to PSI.
The Application Accelerator helps candidates organize these stages and reduce confusion about the order of the licensing process. It supports application readiness by focusing attention on the contractor application, supporting records, qualifying-party information, testing authorization, and final review.
The Mississippi State Board of Contractors identifies Boiler Installation and Repair as a test-required specialty classification within the mechanical category. The classification involves the installation, maintenance, and repair of boilers and associated gas and steam piping for residential, commercial, and industrial use.
The classified scope includes power boiler installations, hot-water heating systems, steam fitting, fire-tube and water-tube steel power boilers, low-pressure hot-water heating boilers, piping, fittings, valves, gauges, pumps, radiators, convectors, fuel-oil tanks, fuel-oil lines, chimneys, flues, heat insulation, and associated equipment.
The classification may also include solar heating equipment associated with boiler and hydronic systems, as well as welding that is part of the classified boiler work. Contractors should perform only work covered by their issued classification and any other credentials required for the project.
Applicants must identify a qualifying party who satisfies the examination requirement for the business. The application must establish the qualifying party’s relationship with the company and include the supporting documentation requested by the Board.
Mississippi contractor applicants must also complete the Mississippi Law and Business Management examination unless an applicable Board rule or approved waiver changes the requirement. The Law and Business Management test is separate from the Boiler Installation and Repair trade examination.
Business names and identifying information should remain consistent across the contractor application, entity-registration documents, insurance records, financial information, tax records, and other supporting materials. Incomplete or inconsistent information can delay the licensing process.
The following references are identified for use with the Mississippi Boiler Installation and Repair examination:
Candidates should use the listed editions when preparing for the examination. The International Mechanical Code and International Fuel Gas Code must match the specified editions because the examination’s code questions are based on those editions.
A strong study plan should follow the examination content outline. Begin with boilers because that subject represents the largest group of questions. Review boiler types, components, heat transfer, combustion, controls, operation, steam production, hot-water systems, accessories, efficiency, and common operating problems.
Next, focus on valves, controls, piping, and traps. Learn the purpose and operation of pressure-reducing valves, safety valves, check valves, control valves, steam traps, expansion devices, gauges, temperature controls, pressure controls, and system-protection components.
Pump preparation should include pump types, system head, flow, pump curves, efficiency, cavitation, variable-speed operation, system resistance, control methods, and troubleshooting. Practice identifying how changes in piping or system demand affect pump operation.
Code preparation should involve direct use of the 2021 International Mechanical Code and 2021 International Fuel Gas Code. Become familiar with chapter organization, definitions, tables, required clearances, piping rules, venting provisions, combustion-air requirements, testing procedures, and appliance installation requirements.
Safety review should include applicable OSHA requirements and practical boiler-work hazards. Study personal protective equipment, fall prevention, electrical safety, welding and cutting, confined work areas, material handling, tools, ladders, scaffolds, and safe equipment operation.
Use practice questions to improve both technical knowledge and reference-navigation speed. Identify the main term in the question, determine the appropriate book, locate the relevant chapter or code section, and confirm the answer from the supporting text.
