Discover the essential regulations for mechanical systems with the 2021 International Mechanical Code (IMC). This indispensable resource establishes minimum standards through both prescriptive and performance-related provisions, ensuring safety and efficiency in mechanical system installations.
Developed with broad-based principles, the IMC enables the incorporation of new materials, methods, and designs, promoting innovation while maintaining rigorous standards. Key updates in the 2021 edition include requirements such as:
– Clothes dryer exhaust terminals positioned at least 3 feet from any building opening.
– Specific smoke and flame index limits for polyurethane spray-applied foam on exterior ducts in attics and crawl spaces.
– Mandated provision of approved access for inspection and maintenance of fire and smoke dampers.
– Updated refrigerant tables to include new refrigerants for improved accuracy.
– Addition of condensate termination identification markings and discharge restrictions.
– Relaxation of separation requirements for approved factory-built combination intake/exhaust terminations.
– 30% reduction in minimum mechanical ventilation for whole-house balanced ventilation systems, promoting energy efficiency.
– Mandatory continuous operation for manicure and pedicure station exhaust systems to ensure air quality.
– Requirement for horizontal cleanout of grease ducts within 3 feet of a horizontal discharge fan to facilitate maintenance.
