2021 Uniform Mechanical Code Soft Cover w/Tabs

The 2021 edition of the Uniform Mechanical Code (UMC®) represents the most current approaches in the mechanical field. It is the seventh edition developed under the ANSI Consensus process is designated as an American National Standards by the American National Standards Institute (ANSI). Furthermore, it addresses specific provisions for low flammability refrigerants such as A2L and B2L; which makes it one of the first codes in the industry to address specific provisions for these low Global Warming Potential (GWP) refrigerants. Contributions to the content of this code were made by every segment of the built industry, including such diverse interests as consumers, enforcing authorities, installers/maintainers, labor, manufacturers, research/standards/ testing laboratories, special experts and users.

The UMC provides complete requirements for the installation and maintenance of heating, ventilating, cooling and refrigeration systems, while at the same time allowing latitude for innovations and new technologies. Key changes to the 2021 UMC include:

  • New Appendix F – Geothermal Energy Systems

  • New guards and rails requirements for installation of equipment and appliances on roofs

  • New ventilation requirements for transient and nontransient occupancies

  • New ventilation requirements for indoor air quality for residential occupancies

  • Revisions to the requirements for air ducts, including factory-made air ducts and dampers

  • New provisions for factory-built grease ducts

  • New provisions for refrigeration systems, including pressure-limiting devices and hydrostatic expansion

  • Revisions to the sizing requirements for natural gas and propane piping systems

  • Modifications to the pressure rating requirements for hydronic piping applications

  • New requirements for fuel gas piping appliance shutoff valves, test pressure, and overpressure protection devices

  • New tube fastener provisions for radiant heating and cooling

  • New requirements for residential compressed natural gas (CNG) fueling systems

  • New fire-extinguishing equipment and carbon monoxide detection requirements for exhaust systems
