CSA Group Gas Trade Training - Units (1 - 24)

These are various units from the CSA Group Gas Trade Training program. Units include 1 through 24. About 4 have coffee stain on them like in the picture. These books are for the Ontario TSSA gas technician licensing path, mainly the G3 and G2 gas fitter certifications. The 24-unit CSA Gas Trade Training Manuals are used as study material for the Gas Technician 3 curriculum and the higher-level Gas Technician 2 curriculum. I'm open to offers. I can't upload pictures of all the books so feel free to message me and I'll send you a picture of each book.
