Prepare for the Idaho HVAC Specialty Journeyman examination with online practice questions designed around the fuel-gas code topics included in the current state exam. This exam-preparation product focuses on the 2018 International Fuel Gas Code (IFGC), the approved reference used for the Idaho HVAC Specialty Journeyman examination.
The Idaho HVAC Specialty Journeyman credential is a specialized HVAC license covering a defined scope of work involving hearth appliances, non-duct-connected oil furnaces, associated fuel-gas piping, and venting dedicated exclusively to those installations. The license does not include plumbing, electrical, or duct work.
This online practice-question product includes 3 months of access, giving candidates time to work through practice questions repeatedly, review difficult subjects, strengthen code-navigation skills, and become more familiar with the structure of the 2018 International Fuel Gas Code before test day.
The current Idaho HVAC Specialty Journeyman examination contains 50 questions, allows 120 minutes, and requires a minimum passing score of 70. The examination is open book and is administered through PSI for the Idaho Division of Occupational and Professional Licenses.
The exam covers all seven chapters of the 2018 International Fuel Gas Code. Candidates should be prepared for questions involving scope and administration, definitions, general regulations, gas piping installations, chimneys and vents, specific appliances, and gaseous hydrogen systems.
Online practice questions provide an active way to prepare for a code-based licensing examination. Instead of simply reading the IFGC, candidates can practice identifying the topic being tested, locating the applicable section or table, reviewing exceptions and limitations, and applying the code requirement to an exam-style situation.
Because the official examination is open book, strong preparation includes both subject knowledge and efficient reference navigation. Candidates who become comfortable moving between IFGC chapters, sections, and tables can use their testing time more effectively than candidates who rely on broad searches for every question.
The Idaho HVAC Specialty Journeyman examination is administered through PSI for the Idaho Division of Occupational and Professional Licenses.
The current published examination blueprint distributes the 50 questions as follows:
Chapter 4, Gas Piping Installations, is the largest individual examination category with nine questions. Chapter 5, Chimneys and Vents, follows with eight questions. Chapters 3, 6, and 7 each contain seven questions, while Chapters 1 and 2 each contain six.
This distribution makes it important to study the entire IFGC rather than concentrating exclusively on gas piping. General installation requirements, definitions, appliance requirements, venting, and Chapter 7 material all represent meaningful portions of the test.
The Idaho HVAC Specialty Journeyman examination is an open book test.
The approved reference allowed in the examination center is the 2018 International Fuel Gas Code. Candidates are responsible for bringing their own approved copy to the testing center.
Pre-exam highlighting, underlining, and permanent indexing are permitted. Candidates may not write in their reference during the examination session. Additional loose papers and temporary markers such as removable Post-it-style notes are prohibited.
Preparing the IFGC before test day can help make open-book navigation more efficient. Permanent tabs can be used to identify major chapters and frequently referenced subjects when prepared in accordance with the current examination rules.
Candidates should also practice finding information without depending entirely on an index. If a question clearly concerns pipe sizing, the candidate should recognize Chapter 4 as a likely starting point. A venting question should point toward Chapter 5, while an appliance-specific installation question may lead to Chapter 6.
The examination allows 120 minutes for 50 questions, an average of approximately 2.4 minutes per question. Efficient code navigation can preserve time for questions that involve tables, multiple code provisions, or careful interpretation.
Idaho HVAC Specialty Journeyman licensing is administered by the Idaho Division of Occupational and Professional Licenses. Idaho provides an examination pathway and an education pathway for this specialty license.
Idaho requires an HVAC Specialty Journeyman applicant to document 2,000 hours of supervised specialty HVAC installation work.
Applicants have two qualification pathways. Under the examination pathway, the applicant must pass the Board-approved examination and complete the required 2,000 hours of supervised specialty HVAC experience.
Under the education pathway, the applicant must complete at least 60 hours of education in fuel-gas code and piping installation methods and document the same 2,000 hours of supervised specialty HVAC installation work.
The Idaho HVAC Specialty Journeyman license has a defined scope. A Specialty Journeyman is permitted to install hearth appliances and non-duct-connected oil furnaces, along with the associated fuel-gas piping and venting dedicated exclusively to those installations.
The specialty license does not include plumbing, electrical, or duct work. Candidates should understand this limitation because it distinguishes the specialty credential from Idaho's broader HVAC Journeyman license.
Fuel-gas code knowledge is central to the examination because the permitted work involves fuel-gas piping, appliance installation, combustion and installation requirements, and venting systems. Candidates should understand how the IFGC regulates both the piping supplying an appliance and the venting and installation conditions affecting the appliance itself.
Idaho currently uses the 2018 International Fuel Gas Code among its adopted HVAC codes. The 2018 IFGC is also the approved examination-room reference for the HVAC Specialty Journeyman examination.
Idaho does not currently require continuing education for HVAC license renewal. The Specialty Journeyman license is issued on a three-year term under the state's HVAC licensing structure.
IFGC Chapter 1 — Scope and Administration: Approximately six questions come from Chapter 1. Review the purpose and scope of the code, applicability, approvals, permits, inspections, and administrative requirements.
IFGC Chapter 2 — Definitions: Approximately six questions come from Chapter 2. Definitions can affect how requirements throughout the code are interpreted, so candidates should become familiar with the terminology used for appliances, vents, piping systems, combustion air, equipment, and fuel-gas components.
IFGC Chapter 3 — General Regulations: Approximately seven questions are drawn from Chapter 3. Review appliance and equipment location, structural considerations, combustion air, installation requirements, access, clearances, protection, and general fuel-gas system provisions.
Combustion Air: Combustion-air questions may require candidates to identify room conditions, calculate required openings, determine acceptable air sources, or recognize when mechanical combustion-air provisions apply. Practice reading both the general requirements and any applicable exceptions.
IFGC Chapter 4 — Gas Piping Installations: Approximately nine questions come from Chapter 4, making it the largest examination category. Candidates should devote substantial preparation time to this chapter.
Gas-Pipe Sizing: Practice determining developed length, system pressure, allowable pressure drop, connected appliance loads, and the proper sizing table. Pipe-sizing questions require careful attention to both the information presented in the problem and the conditions stated in the table.
Piping Materials and Installation: Review approved piping materials, joining methods, protection, supports, concealed piping, piping through structural members, outdoor installations, and corrosion protection.
Valves and Regulators: Study shutoff-valve requirements, regulator locations, accessibility, pressure control, venting, and equipment connections.
Testing and Purging: Become familiar with pressure-testing procedures, test pressures, prohibited test media, leak checks, purging requirements, and safety-related provisions for placing systems into service.
IFGC Chapter 5 — Chimneys and Vents: Approximately eight questions come from Chapter 5. Venting is one of the most important subjects on the specialty exam because the Idaho license specifically authorizes venting dedicated to qualifying appliances.
Vent Connectors: Review permitted materials, sizing, slope, length, support, clearance from combustibles, connection requirements, and common-vent conditions.
Vent Sizing: Practice reading applicable venting tables and identifying the correct values based on appliance input, vent height, lateral length, vent type, and appliance configuration.
Vent Terminations: Review termination requirements involving roofs, walls, openings, mechanical air intakes, building features, and other conditions that affect safe vent discharge.
IFGC Chapter 6 — Specific Appliances: Approximately seven questions are drawn from Chapter 6. Review appliance-specific installation requirements, clearances, connections, controls, combustion air relationships, and equipment restrictions.
Hearth Appliances: Because hearth appliance installation is a core part of the Idaho Specialty Journeyman scope, candidates should pay close attention to appliance placement, clearances, venting, fuel-gas connections, and applicable manufacturer and code requirements.
IFGC Chapter 7 — Gaseous Hydrogen Systems: Approximately seven questions come from Chapter 7. Do not overlook this chapter simply because it may be less familiar than ordinary fuel-gas piping. It carries the same approximate question count as Chapters 3 and 6.
Code Navigation: Practice determining the likely chapter before searching. Definitions lead to Chapter 2, general equipment requirements to Chapter 3, piping to Chapter 4, venting to Chapter 5, and appliance-specific provisions to Chapter 6.
Timed Practice: The exam allows 120 minutes for 50 questions. Practice under time limits to strengthen both code-navigation efficiency and decision-making when a question requires a more detailed lookup.
1 Exam Prep helps Idaho HVAC Specialty Journeyman candidates prepare through organized, trade-focused, practice-oriented study. With 3 months of access, candidates can work through online practice questions repeatedly and return to topics that need additional attention.
The practice structure covers all seven chapters of the 2018 International Fuel Gas Code. Candidates can review general regulations, definitions, combustion air, gas piping, pipe sizing, testing, purging, valves, regulators, chimneys, vents, appliances, and gaseous hydrogen systems.
Because the examination is open book, 1 Exam Prep also supports reference-navigation practice. Candidates can develop a consistent method of identifying the subject, locating the applicable IFGC chapter and section, checking relevant tables and exceptions, and applying the code requirement to the question.
Repeated practice can help identify weaker areas. A candidate may be comfortable with appliance installation but need more work with gas-pipe sizing, combustion-air calculations, vent tables, regulator requirements, or Chapter 7. The 3-month access period provides time to revisit those areas rather than relying on a single study session.
Trade-focused preparation also helps connect field experience with code language. Candidates who already work around hearth appliances, fuel-gas piping, regulators, shutoff valves, vent connectors, and related equipment can use practice questions to reinforce how those real-world installations are addressed in the IFGC.
The goal is to build stronger familiarity with the 2018 IFGC, improve open-book navigation, reinforce the specialty scope, and provide a consistent practice structure leading up to test day. Organized preparation can help candidates approach the Idaho HVAC Specialty Journeyman examination with a clearer understanding of the material and testing format.
