What is the minimum required slope of a vent connector?

The minimum required slope of a vent connector is 1/4" rise per foot. This requirement ensures that condensate is effectively drained away from the vent system, preventing the accumulation of moisture that could potentially lead to corrosion or blockages. Proper drainage is vital for maintaining the efficiency and functionality of the venting system, as any buildup of moisture can hinder the flow of gases and may introduce safety hazards. A slope of 1/4" per foot is a commonly accepted industry standard, allowing for adequate drainage while maintaining a manageable angle for the installation of the vent connector. This practice helps to ensure the longevity and reliability of the venting system in a building, which is crucial for overall safety and performance.
