Before installing a boiler, refrigeration system, or pressure piping, above NPS3, you’ll need to provide a Canadian Design Registration Number (CRN). Manufacturers can submit their design specifications of the device registered to obtain a CRN. View details on registering a design and pneumatic testing.
