Test Information and Study Materials

The ICC 774 MN-MI exam focuses on applied ventilation knowledge. The strongest prep approach is to study by category weight and build the skill of locating the correct requirement quickly. Use the guide below to align your study sessions with the exam’s structure.

Duct Construction and Calculations (30%)
This is one of the largest sections of the exam. Focus on how ducts are constructed, supported, and specified, along with calculation-based thinking that supports proper air movement and system performance. SMACNA is a major support reference here, and your mechanical code reinforces requirements and constraints that impact duct installation. To improve speed, practice locating the duct construction sections and commonly used tables so you can answer quickly under time pressure.

Commercial Kitchens (30%)
Commercial kitchen ventilation is a high-impact exam category. NFPA 96 is included because commercial cooking operations require specialized ventilation control and fire protection practices. Study with a safety-first mindset: the questions often reflect real risk—grease, heat, and the need for correct system design and maintenance. Your goal is to know how to find the right NFPA 96 section quickly and apply it to scenario-style questions.

Combustion Air/Venting (15%)
Combustion air and venting topics are tied to safe operation and correct installation. Strengthen your understanding of how combustion appliances behave, what correct venting aims to accomplish, and how requirements are applied. Code familiarity matters here—build speed finding combustion-air-related topics in your Minnesota Mechanical and Fuel Gas Code reference.

Residential Make Up Air (10%)
Tighter homes and higher performance envelopes make make-up air and residential ventilation more important. Use your code reference (with ASHRAE standards included) to reinforce the intent and practical expectations behind residential ventilation and make-up air concepts.

Ventilation (10%)
Ventilation questions may test principles, definitions, and requirements—especially how ventilation expectations connect to installation decisions. This is a good place to build confidence by learning how to locate key ventilation provisions and confirm details in the codebook quickly.

General (5%)
General questions are often about broad warm air/ventilation knowledge and code familiarity. Treat this as a chance to pick up reliable points by building a strong foundation and steady reference navigation habits.

Study workflow that fits an open-book exam:

• Focus on the big categories first: Spend most of your time on Duct Construction/Calculations and Commercial Kitchens because they make up 60% of the exam.
• Build fast “book selection” instincts: Train yourself to choose the correct reference quickly based on the topic.
• Practice timed drills: Run sessions where you answer questions and locate supporting sections with the clock on.
• Track your most-used sections: Keep notes on the sections you return to often so your speed improves each time.
