Your ICC F29 Master Mechanical (2015 IMC/IFGC) Study Plan
Your books are your best friend on this exam. It's open book, so the references on the bulletin's list are what you'll use on test day. Get your own copies in the editions the bulletin names.
Get to know them early. Spend time with each book's table of contents and index until you can find any major subject quickly. On an open-book exam, finding answers fast is the skill that counts.
Make the books yours. Highlight the sections you keep coming back to. Check the bulletin's rules on tabs and markings before you add any.
Put your energy where the points are. General Requirements and Plan Reading and Duct Systems make up 45% of the exam, so start there.
Practice with the clock running. Our timed practice exams help you build the pace the real exam needs: about 2 minutes 24 seconds per question. Every attempt is another rep.
Keep going until you pass practice exams consistently. One good score is a great start. A few passing scores in a row is how you know you're ready.
Books You'll Need for the ICC F29 Master Mechanical (2015 IMC/IFGC) Exam
The listed references for this exam are the 2015 International Mechanical Code and the 2015 International Fuel Gas Code.
Where to get them:
Test Day Tips
Start with a quick pass through the whole exam. Answer every question you're sure about and bookmark the rest. Every exam lets you return to bookmarked questions, so nothing is lost by moving on.
Then come back to your bookmarks and work through them one at a time. Keep an eye on the clock: you have 4 hours for 100 questions, which is about 2 minutes 24 seconds per question. Before you finish, make sure every question has an answer. A blank can't earn a point.
Study Tips
Practicing against a ticking clock is the best way to beat exam-clock anxiety. Use these timed tests to build your pacing, so you learn to move steadily and never burn too long on a single question. By test day, the format feels routine.
You're given plenty of time, so use as much of it as you need. Don't get rattled when other people finish early — finishing first isn't a prize. Work at your own steady pace and review your answers before you submit.
Don't overlook any information in the question—every detail may be essential to finding the correct answer. Unlike the answer choices, nothing in the question is a red herring. If two seemingly unrelated topics appear, assume they are connected; finding that connection is likely the key to solving the problem.
Read the explanation for every question — right or wrong. Understanding the underlying rule lets you answer reworded questions you've never seen, instead of memorizing specific answers.
Several 25–30 minute sessions across the week beat one long cram. Spaced repetition moves facts into long-term memory so they stick through exam day.
Try These ICC F29 Master Mechanical (2015 IMC/IFGC) Practice Questions
Give these a try. They come from our practice question bank, each with its answer and reference.
Sample 1 — Exhaust and Ventilation Systems
Question: A grease duct system serving a Type I hood uses an in-line exhaust fan with duct connected to both the inlet and outlet sides. Cleanouts are required on each side of the fan. What is the maximum distance those cleanouts may be located from the fan duct connections?
- A. 3 feet
- B. 10 feet
- C. 5 feet
- D. 20 feet
Correct Answer: A
IMC 2015, Section 506.3.8.2 requires a cleanout on both the inlet and outlet side of an in-line fan (except where no duct connects to that side), located within 3 feet of the fan duct connections.
Reference: IMC 2015 Section 506.3.8.2
Sample 2 — Chimneys and Vents
Question: A Type B-W gas vent serves a listed vented wall furnace. The vent must terminate at a minimum vertical height above the bottom of the wall furnace of:
- A. 12 feet
- B. 3 feet
- C. 5 feet
- D. 8 feet
Correct Answer: A
IFGC 2015 Section 503.6.5 requires a Type B-W gas vent to terminate not less than 12 feet in vertical height above the bottom of the wall furnace. The 5-foot figure in the same section applies to Type B or L vents measured above the highest connected draft hood or flue collar.
Reference: IFGC 2015 Section 503.6.5
Sample 3 — Fuel Supply Systems
Question: A new gas piping system with a proposed maximum working pressure of 2 psig is being pressure tested using a mechanical gauge. Based on the minimum required test pressure for this system, what is the maximum full-scale (highest end of scale) reading permitted on the gauge used?
- A. 20 psi
- B. 30 psi
- C. 15 psi
- D. 6 psi
Correct Answer: C
IFGC 2015, Section 406.4.1 requires a test pressure of not less than 1 1/2 times the proposed maximum working pressure but not less than 3 psig; 1.5 x 2 psig = 3 psig, so the test pressure is 3 psig. Section 406.4 requires that mechanical gauges have a range such that the highest end of the scale is not greater than five times the test pressure: 5 x 3 = 15 psi.
Reference: IFGC 2015 Sections 406.4 and 406.4.1
Sample 4 — Combustion Air
Question: An oil-fired warm-air furnace is being installed in a mechanical room. Under the mechanical code, combustion air for this appliance must be provided in accordance with which document?
- A. NFPA 31
- B. The appliance manufacturer's installation instructions
- C. The International Fuel Gas Code
- D. NFPA 54
Correct Answer: A
Per IMC 2015 Section 701.1, oil-fired appliances shall be provided with combustion air in accordance with NFPA 31. Solid fuel-burning appliances follow the manufacturer's installation instructions, and gas-fired appliance combustion and dilution air follows the International Fuel Gas Code.
Reference: IMC 2015 Section 701.1
