What is the minimum height a damper must be located above the lentil?

The minimum height at which a damper must be located above the lintel is crucial for ensuring that the damper functions correctly while also adhering to safety and code requirements. A damper is an essential component in HVAC systems, as it helps regulate airflow and prevent backdrafts.

Installing the damper too close to the lintel can create airflow issues or impede its operation, especially when the structure expands or contracts due to temperature changes. Additionally, placing the damper at this specified height helps maintain adequate clearance for maintenance and potential servicing.

The requirement of eight inches above the lintel is typically aligned with standard building codes, ensuring that the design and installation of the damper allow for proper airflow and operational effectiveness. Following these standards not only facilitates efficient HVAC performance but also contributes to the overall safety and structural integrity of the building.
