scope:

2.0 SCOPEThis Standard applies to HVAC equipment/components being installed in new and existingresidential and commercial buildings:

2.1 EQUIPMENT TYPES

2.1.1 Unitary air conditioners, air-source/water-source heat pumps, and geothermalheat pumps,

2.1.2 Furnaces (gas-fired, oil-fired, electric, and other),

2.1.3 Boilers (gas-fired, oil-fired, electric, and other).EXCEPTIONS:Due to differing design aspects and control/operation situations, built-up systems(i.e., chillers, custom or specialty-built penthouse units, etc.) are not included inthis Standard. Buildings employing built-up systems are generally designed byarchitects or professional engineers. Additionally, commercial buildings usingbuilt-up equipment are more likely to benefit from increased owner scrutiny viabuilding commissioners, owner agents, etc.

2.2 EQUIPMENT SYSTEMS / COMPONENTS
