Installing a Plenum Box
To install plenum boxes, an installer will follow these steps:
– Measure the size and location of the ductwork and the air outlet.
– Cut a hole in the ductwork that matches the shape and size of the plenum box inlet.
– Insert the plenum box into the hole and secure it with screws or clamps.
– Connect the air outlet to the plenum box outlet with flexible duct or metal fittings.
– Seal any gaps or leaks with duct tape or mastic.
– Test the airflow and noise level of the system and adjust as needed.
