Exam Details

The Delaware Master HVACR Restricted – Gas Piping classification applies to professionals seeking authority to provide HVACR services within the gas piping specialty. A restricted license limits the holder’s professional scope to the specialty identified on the license rather than providing the broader authority associated with an unrestricted Delaware Master HVACR license.

The examination evaluates the candidate’s ability to understand and apply principles associated with gas piping work. Preparation should include fuel gas code navigation, piping materials, system installation, sizing, plan reading, pipefitting mathematics, safety, venting, liquefied petroleum gas, and general trade knowledge.

Important study areas include:

• General gas piping knowledge and terminology
• Fuel gas code definitions and requirements
• Approved piping materials and joining methods
• Gas pipe sizing and system design
• Installation practices and system components
• Valves, regulators, shutoffs, and appliance connections
• Testing and inspection concepts
• Combustion air and venting principles
• Liquefied petroleum gas concepts
• Isometric drawings and plan interpretation
• Pipefitting measurements and calculations
• Workplace and jobsite safety

General knowledge questions may address tools, materials, terminology, common installation practices, system components, and foundational gas piping concepts. Candidates should be able to recognize the purpose of common fittings, controls, valves, regulators, and protective devices used in fuel gas systems.

Sizing and design preparation should include practice using tables and evaluating the conditions presented in a problem. A candidate may need to identify the correct table, understand the measurement basis used by that table, follow the proper row and column, and select a pipe size that satisfies the stated conditions.

System installation questions may involve materials, supports, protection, connections, shutoff valves, sediment traps, appliance connections, testing, prohibited locations, and installation procedures. Candidates should read each question carefully because a small detail may change which code requirement applies.

Plan-reading and isometric questions may require candidates to interpret piping layouts, symbols, fittings, branches, offsets, elevations, and changes in direction. Mathematical questions may involve fractions, decimals, measurements, conversions, areas, angles, lengths, offsets, and practical pipefitting calculations.

Safety is also an essential part of gas piping work. Preparation should address hazard recognition, personal protective equipment, tool safety, material handling, fire prevention, excavation awareness, ladder use, and safe work practices around fuel gas systems.

Open Book Test

The Delaware Master HVACR Restricted – Gas Piping examination is an open-book test. Candidates may use the references approved for the examination, subject to the current testing provider’s rules for books, tabs, highlighting, notes, inserts, and other materials.

Open-book testing does not eliminate the need for detailed preparation. Candidates must know which reference is most likely to contain the answer, where the applicable information is located, and how to interpret it correctly. Searching an unfamiliar book from the first page to the last page can consume valuable testing time.

The highlighted and tabbed books included in this package are designed to support efficient navigation. The tabs can direct your attention toward commonly used chapters and subject areas, while highlighting helps identify important definitions, requirements, tables, formulas, and safety concepts.

Use the books regularly throughout your course access period. When studying a topic, locate the supporting material in the appropriate reference rather than relying only on lesson notes. Repeated navigation helps you become familiar with the index, table of contents, chapter organization, code structure, tables, and cross-references.

A practical open-book method is to identify the question category before opening a book. A question involving workplace hazards may point to Basic Safety. A sizing, venting, appliance, or installation question may require the International Fuel Gas Code. A question involving offsets, dimensions, or calculations may be addressed in Mathematics for Plumbers and Pipefitters.

Read the entire question before beginning a reference search. Pay attention to words such as minimum, maximum, required, permitted, prohibited, most appropriate, and least appropriate. These terms can significantly change the meaning of a question and the answer you should select.

Licensing Steps

The Delaware Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners regulates Master HVACR and Master HVACR Restricted licenses. Candidates pursuing licensure by examination must complete the state application process and receive approval before sitting for the master examination.

1. Select the appropriate classification. Apply for the Delaware Master HVACR Restricted license and select Gas Piping as the restricted specialty.
2. Create or access a DELPROS account. Delaware professional license applications are managed through the Delaware Professional Regulation Online Services system.
3. Complete the application. Enter the personal, education, apprenticeship, employment, experience, and licensing information requested for the selected pathway.
4. Submit supporting documentation. Arrange for the required certificates, employment verifications, experience records, examination information, and license verifications to be submitted as directed.
5. Complete any additional required testing. Applicants without the qualifying apprenticeship credential may be required to complete the applicable apprenticeship equivalency or bypass examination requirements.
6. Receive Board approval for the master examination. The Board reviews the application and determines whether the candidate meets the conditions required to sit for the exam.
7. Register with the testing provider. After approval, follow the registration and scheduling instructions provided for the Delaware examination.
8. Prepare and take the examination. Study the approved references, complete course lessons and practice activities, and follow all testing-day instructions.
9. Complete remaining licensing requirements. The Board must receive the examination result and all required documentation before a license can be issued.

Applicants should begin collecting documents early. Employment verification may require assistance from current or former supervisors. Apprenticeship certificates, licensing records, or other official documents may need to be submitted by a third party rather than directly by the applicant.

The professional license application and examination process are separate from purchasing this preparation package. The books and course support exam preparation, but applicants remain responsible for submitting their application, proving eligibility, paying government or testing fees, attending the examination, and satisfying all Board requirements.

State Requirements

Delaware recognizes both unrestricted Master HVACR licenses and Master HVACR Restricted licenses. A restricted license authorizes services only within the specialty identified on the license. Gas Piping is one of the restricted specialties available through the Delaware Board.

An applicant with a qualifying journeyman certificate obtained after completing an accepted HVACR or restricted HVACR apprenticeship program must document the required post-apprenticeship experience under appropriate supervision. Experience earned before receiving the journeyman certificate does not count toward the post-apprenticeship experience requirement.

An applicant who does not possess the qualifying journeyman certificate must document the required years of HVACR or restricted HVACR experience under the direct supervision of an appropriately licensed master professional. The applicant may also be required to complete the applicable apprenticeship equivalency or bypass examination approved for the restricted specialty.

Delaware licensing requirements also address examination performance, professional conduct, and appropriate certification for handling regulated refrigerants when applicable to the licensing pathway. Applicants must provide the evidence requested by the Board and answer application questions accurately.

The Board determines whether an applicant’s education, apprenticeship, work experience, examination results, and supporting documents meet Delaware requirements. Purchasing an exam-preparation package does not replace any state requirement and does not guarantee application approval, examination success, or license issuance.

A Delaware professional license is not the same as a Delaware business license. Professionals planning to operate a contracting business may need separate business registration, tax accounts, insurance, local approvals, permits, and other operational credentials. The restricted professional license controls the type of HVACR work the individual is authorized to perform.

Test Information and Study Materials

Begin your preparation by creating a weekly study schedule. Divide the material into manageable categories, such as safety, gas code navigation, sizing, system installation, venting, LP gas, plan reading, and trade mathematics. A structured schedule can prevent you from spending too much time on familiar subjects while overlooking weaker areas.

Pair course lessons with hands-on reference work. After completing a lesson, open the relevant rental book and locate the rules, tables, formulas, or explanations associated with that topic. This reinforces the lesson and develops the navigation skills needed during the exam.

Practice gas pipe sizing carefully. Learn how to identify the correct table and determine which values control the calculation. Work through multiple examples because a change in system length, demand, pressure, or method may affect the required answer.

Review venting and combustion air as application-based subjects rather than isolated definitions. Understand how appliance type, installation arrangement, venting method, and location affect the applicable requirements. Use diagrams and examples when available to strengthen visual understanding.

Work on trade mathematics consistently. Short, frequent practice sessions can be more productive than attempting to relearn every formula immediately before the examination. Show each step, track units, and review why an incorrect answer occurred.

Complete timed practice questions as your exam date approaches. Attempt familiar questions first, mark questions requiring longer searches, and return to them after completing the rest. This method can help you use the testing period more effectively.

Before the exam, review your current scheduling notice and candidate instructions. Confirm the acceptable identification, arrival procedures, approved reference rules, calculator policy, testing location, and any restrictions that apply to your appointment.
