The International Fuel Gas Code, 2018 should be studied carefully for gas-fired boiler and fuel gas piping topics. Candidates should review gas piping systems, pipe sizing concepts, pressure, shutoff valves, sediment traps, appliance connectors, venting, chimneys, combustion air, appliance installation, testing, inspection, and safety provisions. Fuel gas questions often require close attention to details because the correct answer may depend on the specific equipment or installation condition described in the question.

The OSHA 29 CFR Part 1926 reference supports safety-related exam questions. Candidates should review jobsite safety, personal protective equipment, ladders, scaffolds, fall protection, electrical safety, excavation hazards, hand and power tools, material handling, housekeeping, hazard communication, and safe work practices. Residential boiler and solar heating contractors may work around mechanical spaces, roofs, ladders, gas piping, hot water systems, electrical components, solar heating equipment, and heavy materials, so safety preparation should not be ignored.

Solar preparation should focus on the concepts tied to residential solar heating systems. Candidates should review collection loops, components, installation, maintenance, mounting, operating principles, and solar system piping. The solar material should be studied as part of the broader boiler and heating system scope, especially where solar heating equipment interacts with hydronic or mechanical systems.

Because this is an open-book exam, candidates should prepare their books before the testing appointment. Permanent tabs can help identify important chapters, definitions, tables, fuel gas sections, boiler sections, mechanical equipment requirements, and OSHA safety topics. Highlighting and annotations should be completed before the examination session. Over-marking can make a reference harder to use, so candidates should focus on clear organization and the sections most likely to be needed during the test.

Practice should include timed questions and reference lookup. Some questions may be answered from trade knowledge, while others require code navigation. A strong exam strategy is to answer familiar questions first, mark difficult questions, and return to them after making progress. This keeps one difficult lookup question from consuming too much exam time.

Candidates should also practice choosing the correct reference. OSHA safety questions generally belong in 29 CFR Part 1926. Boiler, heating, hydronic heating, mechanical equipment, combustion air, ventilation, and equipment installation questions often belong in the International Mechanical Code. Gas piping, gas-fired appliances, venting, chimneys, connectors, and fuel gas safety questions often belong in the International Fuel Gas Code.
