What is the maximum horizontal length for a vent connector?

The maximum horizontal length for a vent connector is 18 inches. This length is critical for ensuring proper venting and maintaining the efficiency of the appliance connected to the vent system. A horizontal vent connector that exceeds the recommended length can lead to insufficient draft, resulting in the potential buildup of combustion gases within the space, unsafe operation of the appliance, and increased risk of carbon monoxide exposure.

Maintaining this maximum length helps facilitate the necessary airflow and ensures that combustion gases are efficiently expelled from the appliance. The specified limits are established by safety regulations and best practices to protect both occupants and property from hazards associated with improper venting. Adhering to these guidelines is essential for the safe and effective operation of propane-fueled appliances.
