Chimney Safety Institute of America (CSIA) Certification Practice Test

What is the minimum rise or pitch required per foot for connectors?

1. 1/8"

2. 1/4"

3. 1/2"

4. 3/4"

The correct answer is: 1/4"

The minimum rise or pitch required per foot for connectors is established to ensure proper drainage and prevent the accumulation of moisture within the flue system. Having a rise of at least 1/4 inch per foot allows for adequate flow of condensate away from the appliance and into the chimney system. This is crucial for reducing the risk of corrosion and water damage, which can significantly affect the longevity and safety of the chimney and connected appliances. In this context, the requirement is based on industry standards for vent connectors, which are generally designed to carry flue gases safely while minimizing the chance of blockage due to moisture buildup. A pitch of 1/4 inch per foot strikes a balance between allowing proper drainage and maintaining an effective and efficient venting system.
