CSD-1 gas trains

What makes a gas train CSD-1 compliant? What size boilers need CSD-1 compliant gas train components? If a manufacturer certifies their boiler as CSD-1 out of the box, can an inspector demand a listing of all CSD-1 components as well as who manufactured said components, serial numbers, etc.? What is a "shop-built" boiler and/or burner? Thanks, Gary
