Exam Details

The Delaware Master HVACR Restricted Heating – Hydronic Systems and Gas Piping examination evaluates knowledge connected with the design, installation, construction, maintenance, service, repair, alteration, and modification of hydronic systems and gas piping serving hydronic equipment.

Hydronic heating systems use water, steam, or another liquid to transfer heat. Candidates should understand how boilers, pumps, valves, piping, controls, expansion devices, air-removal components, heat emitters, and related equipment work together to produce and distribute heat safely.

The examination contains 80 questions and provides three hours for completion. The published subject areas include:

• General Knowledge
• Hydronic Systems
• Piping, Pumps, and Valves
• Fuel Gas and Oil
• Low- and High-Pressure Boilers
• Water
• Testing and Inspection

General knowledge preparation may involve heat transfer, pressure, temperature, combustion, controls, tools, materials, safety devices, system terminology, and standard HVACR practices. Candidates should understand how individual components affect the performance and safety of the complete heating system.

Hydronic-system questions may address circulation, zoning, heat distribution, system pressure, temperature control, expansion, air elimination, radiation equipment, and common piping arrangements. Candidates should be prepared to trace the movement of water or steam through a system and recognize the purpose of each component.

Piping, pump, and valve questions may involve piping materials, joining methods, circulation, pump placement, flow direction, isolation, balancing, check valves, control valves, and system maintenance. A question may require the candidate to identify how a component affects pressure, flow, or system operation.

Fuel gas and oil preparation may involve supply piping, regulators, valves, burners, combustion air, venting, appliance connections, testing, and safe fuel-system operation. Candidates should understand both the code requirements and the technical principles involved in combustion and fuel delivery.

Boiler questions may address construction, burners, controls, safety devices, operating procedures, pressure, temperature, low-water conditions, inspections, maintenance, and troubleshooting. Water-related questions may involve treatment, makeup water, circulation, expansion, air removal, and conditions that can affect boiler efficiency or service life.

Testing and inspection preparation should include procedures used to evaluate piping, controls, safety devices, equipment operation, and system condition. Candidates may need to recognize an unsafe condition, identify an appropriate test, or determine which component requires inspection.

Open Book Test

The Delaware Master HVACR Restricted Heating – Hydronic Systems and Gas Piping examination is an open-book, timed test. Candidates may use authorized references during the examination while following the testing provider’s current rules for approved books, editions, highlighting, tabs, notes, inserts, calculators, and other materials.

An open-book examination still requires substantial preparation. Candidates have three hours to complete 80 questions, so there is limited time to search through unfamiliar references. Effective preparation combines technical understanding with the ability to identify the right book and locate the applicable information efficiently.

All rental books in this package are highlighted and tabbed. The tabs provide convenient starting points for important subjects, while highlighting draws attention to useful definitions, code sections, diagrams, tables, operating principles, and equipment information. Candidates should still read the complete surrounding material because exceptions, notes, definitions, and table conditions can affect the correct answer.

The International Fuel Gas Code, 2018 supports preparation involving fuel gas piping, system sizing, valves, regulators, appliance connections, combustion air, venting, testing, and installation requirements.

The International Mechanical Code, 2018 supports mechanical-system questions involving boiler installation, mechanical equipment, ventilation, combustion air, exhaust, appliance requirements, and related system provisions.
