Boiler, Pressure Vessels and Refrigeration Installation Permits
Licensed contractors and owners need a permit before they install, operate, or perform maintenance on boilers and refrigeration systems that meet certain specifications. Examples include:
- Hot water or low pressure steam boilers with a heating surface area exceeding 3 m2
- High pressure steam boilers with a heating surface area exceeding 2 m2
- Hot potable water heaters exceeding 120 kW or 400,000 BTUs/h

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.
