Fuel-gas devices used with refrigeration systems shall be installed per _____ _____ _____ code.

Fuel-gas devices used with refrigeration systems must adhere to the International Fuel Gas Code to ensure safe installation and operation. This code provides specific guidelines related to the proper handling, storage, and use of fuel gases, emphasizing safety within the design and installation of fuel-gas systems.

The International Fuel Gas Code addresses critical aspects such as materials, equipment specifications, installation practices, and testing, which are crucial for preventing gas leaks and ensuring proper ventilation. Following these standards helps maintain safety in areas where fuel gas is present, particularly in refrigeration systems where flammable gases may be used.

While other codes like the International Building Code or Fire Safety Code address broader structural and safety concerns, they do not specifically focus on the requirements and regulations relevant to fuel-gas systems. The Mechanical System Code also encompasses various mechanical systems but does not singularly target the unique aspects of fuel gas in refrigeration, making the International Fuel Gas Code the most appropriate reference for this scenario.
