Iowa 2 Hour 2015 IMC Review Chapters 5-11 (Part 2)

In the counterpart to our 2 hour review of Chapters 1-4 and 12-15, this course will contain instruction on the changes to Chapters 5-11, which contain some of the most extensive code changes.

We'll start with a review of the 2016 Iowa Mechanical Code, before we jump into a review of the most significant changes to these chapters of the IMC. We'll begin with a review of Chapter 5, which addresses various exhaust systems, as well as techniques for pressure equalization. It also covers grease duct enclosures, cleanouts, and exhaust systems and hoods such as those in commercial kitchens. We'll also discuss air balance for commercial kitchen ventilation, hazardous exhaust duct penetrations, and energy recovery systems.

In Chapter 6, we'll take a look at duct systems, including return air openings, plenums, joints, dampers, and in Chapter 7, the standards and ratings for certain materials.  

In Chapter 8, we'll talk about the changes to regulations for chimneys and vents, fireplace doors, and evaporative coolers. Chapter 9 will address openings for air.

Finally, Chapter 10 will cover the changes to the low-water cutoffs in boilers, as well as bottom blow-off valves. We'll end the class by covering changes to Chapter 11, which deals with access port protection, refrigerant classifications, and refrigerant piping.
