Hello, I'm Phil, a consulting professional engineer with a masters degree in chemical engineering and a Ph.D. in mechanical engineering.

I'll be your personal coach so you won't be alone in your studies. Scroll down below to see actual coaching conversations where I answered questions to help students understand the material.

correct me if I'm wrong, because I misunderstand the statement of "reduced 10% for each ADDITIONAL multiple of the length allowed by table 505.3.2"

If the connector horizontal length is 22.5 feet so the answer is 20 percent If the connector horizontal length is 30 feet so the answer is 30 percent If the connector horizontal length is 37.5 feet so the answer is 40 percent

The question is: "A 5-inch diameter type B double-wall connector is used to connect a Category I appliance to a chimney with multiple appliances connected. How much does the maximum capacity of the vent connector have to be reduced if the connector horizontal length is 15 feet?"

Answer 1: 10 percent Answer 2: 20 percent Answer 3: 30 percent Answer 4: 40 percent

The correct answer is: Answer 1.

My answer was: Answer 2.

Table 504.3.2 already allows for the length listed. For a 5-inch diameter, the maximum horizontal length of a connector is 7.5 feet WITHOUT any reductions. If you exceed the lengths listed in Table 504.3.2, you must reduce the capacity by 10% for each ADDITIONAL length. In the question, the length is 7.5 feet, so your example of 22.5 feet leading to 20 percent reduction, 30 feet is 30%, 37.5 feet to 40%, is correct.

thanks

One question regarding practice test 2 question 22, why the answer is not B: 22" w and 30" tall?

Or D?

The opening has to be large enough for the largest appliance to be removed. A 22" opening will not allow a 24" diameter hot water heater to get through (unless the water heater is less than 22" tall, I guess, but that would be very unusual). Both appliances could be maneuvered through a 24" x 30" opening. Answer D would be easier, giving you more space to remove the appliances, but C is the minimum.

But how can that furnace to be removed with 24"x30"?

the H is 45"

Both the water heater and the furnace would have to be turned on their sides if the access door is in a wall. If the access door is a ceiling panel, then both appliances could be lowered through the opening.

thx

question where do you find the path to the answer it's not listed for balance calculation

Image

The question is: "Using the drawing above, to what airflow should supply diffuser S3 be balanced?"

Answer 1: a. 50 cfm Answer 2: b. 660 cfm Answer 3: c. 835 cfm Answer 4: d. 1250 cfm

The correct answer is: Answer 2.

My answer was: Answer 3.

This question requires some inference, but it is just an example of reading drawings. The image is a snip from a real drawing for a real project. It isn't stated that the CFM is above the tag, but you have to infer from the question that the CFM is listed. So, all you do is find S3 on the drawing, and you'll see the number 660 above the tag. Therefore, you pick answer 2.

Passed B2, M2, and Also CA's Exams

Good afternoon Chris, thanks for the extra time for that, passed the exam. The questions were right in line with the training received and the practice exams. Passed Commercial Building, and now also Commercial Mechanical. Even though your M2 course was geared towards the international code, I took the CA commercial mechanical exam and passed.

In the practice exams due to CA having some minor changes, answers are slightly different, however the process of reviewing and looking up the answers remains the same. Since you could not just go straight to the sections detailed in the course, it took a bit more referencing the index. On your final practice exam I scored a 40%, however looked up each answer so felt most of that score was more of a reflection of the differences in code. Turned around the next morning and took the CA exam and was done in 90 mins.

Passed both M2 and M3 Exams with Course!

I actually met the two of you (Gabe & Chris) at the EduCode conference in Vegas! I didn't have my business card on me at the time but I work for a building dept. in Delaware. You guys helped me get all of the plumbing certs and now the mechanical certs that ICC offers. I'll be going for electrical next. I'm really glad you guys offer this training, it's hard to come by!

Btw, your practice tests were harder than the ICC mechanical inspector test I took, and about the same level difficulty as the plans examiner test, just to let you know.

I passed the commercial mechanical inspector and plans examiner tests btw, thanks to your program here!

Questions on the exam were similar to the practice tests

Hi Gabe,

I took the International Mechanical Code M2 test this morning and passed!! I am so grateful to you and your company. Your modules were broken down to an understandable level. I really appreciate you giving me extra days to study!! I am still using it to check what answers I might have chosen incorrectly. There were questions on the exam that were very similar to the quiz and Practice tests in the course. Many questions on the two practice tests at the end were much harder than the actual exam, which I believe was a great help.

Three guys from my class for Plumbing Inspector are taking your course for IMC Commercial M2 now. They failed the Exam the first time because they had used a different company. One guy said nothing in the course was on his exam. Funny thing is, "everything" on the exam was taught by you! You actually taught a lot more data and really useful information that will definitely be of use in the future. Sorry for the long email. Can't tell you how happy I am today because of you!!
