2015 UMC Combustion Air 

Passed my LP5 propane test today. Watched your videos over and over thank you so much for your help

This video just helped me pass my Maryland journeymans test…hats off to this fella

great video! great way of explaining combustion air, and how to calculate sizing. hope you put out more on the fuel gas code.

FYI Chapter 7 was relocated to Section 304 in the 2018 and 2021 IFGC books.
