Description
The Weil McLain 383-500-398 Sidewall Vent Termination Kit is a venting component used in HVAC systems to safely discharge flue gases through an exterior wall. It is for 4-inch PVC piping and provides a sealed point that supports proper exhaust airflow while preventing backdraft and outside air intrusion. Commonly used with condensing boilers, it supports safe combustion venting by maintaining correct separation of intake and exhaust paths. This component is typically installed in residential and light commercial heating systems where code-compliant venting is required for efficient boiler operation.
