Question: 1 / 400

What is the purpose of maintaining a minimum pitch in a chimney connector?

To facilitate structural support

To ensure proper drainage of condensate

Maintaining a minimum pitch in a chimney connector is essential to ensure proper drainage of condensate. When combustion appliances operate, especially those with high-efficiency models, they can produce water vapor as a byproduct of combustion. If the chimney connector does not have the appropriate pitch, this condensate can accumulate and lead to moisture-related issues, such as corrosion of the connector or flue. By ensuring the connector is pitched correctly, typically at around a 1/4 inch per foot, any condensate can efficiently drain back into the appliance rather than collect in the connector. This not only helps maintain the integrity of the chimney system but also enhances overall system performance and safety.
