Think about it!
After spending hours in a cram course, listening to an instructor rushing through the provisions of all the code books, plus teaching you how to perform load calculations and size ducts, vents and piping and then covering business and accounting principles, the average attendee will come out of the class with one question on his mind; “What did he say?”
Most of us have been there before.
The Guide is simply the best way to go.
We make learning easy.
Once you’ve read our sections on Manual J (load calculations) and Manual D (duct design) you’ll be looking for a butt kicking machine for not ordering our course earlier. There is simply no easier method for fully understanding these manuals. For example, the Guide condenses Manual J from 627 pages down to 11 pages; Now, that’s making it easy
Because many states are now adding business questions to their HVAC exams, we have included a section on business practices and math. It is written in a language, we in the trade understand. You no longer have to have the skills of a Philadelphia lawyer, mathematician and a CPA to help prepare for the exam.
AN EXCERPT FROM THE GUIDE TAKEN FROM OUR SECTION ON THE FUEL GAS CODE
Single appliance -Table 504.2(1) Sizing vents
What size B vent is needed for a 160,000 BTUH, naturally ventilated appliance if the total vent height is 18’ and the lateral 2’?
Under the height column you have to choose either 15’ or 20’. Remember this: The taller the vent the more capacity it has, therefore, if the 20’ row is used the vent may be under sized. Always use the shorter height.
In this case use 15’. Now use the 2’ lateral and select a vent size under NAT. A 5” vent will handle only 150,000 BTUH, while a 6” vent will handle 225,000 BTUH, therefore select a 6” vent.
See? You already learned something!
