What is the maximum allowable misalignment that is not considered a miter?

The maximum allowable misalignment that is not considered a miter is three degrees. This standard is significant for ensuring proper alignment in HVAC systems, as misalignment can lead to increased wear and tear, inefficiencies, and even system failure.

In practical terms, keeping misalignment to a maximum of three degrees helps maintain optimal airflow and pressure within ducts, enhancing system performance and longevity. While some degree of misalignment can be acceptable in certain installations, exceeding this limit can cause complications, such as noise, vibration, and potential damage to system components. Understanding this limit is crucial for HVAC professionals to ensure that installations meet regulatory standards and operate efficiently.
