What is the minimum required distance for vertical vent installation if it exceeds the specified angle?

For vertical vent installations that exceed a specified angle, there is no minimum distance requirement. This is because the primary consideration in venting is to ensure that the system functions effectively without trapping gases or obstructing airflow.

When the vent exceeds the specified angle, the design typically allows for greater flexibility in its installation to account for changes in elevation or necessary adjustments to accommodate the structure's layout. This flexibility allows installers to focus on ensuring that the vent pipe remains clear and functional, rather than adhering to rigid distance requirements.

In practice, while other options might suggest minimum distances, the absence of a required minimum in this context allows for adaptations that can enhance performance and comply with local building codes, which may prioritize function over strict distance limitations.
