What is the required pitch or rise for connector pipes per foot?

The required pitch or rise for connector pipes is crucial for ensuring proper drainage of condensate and preventing any potential backflow or blockages in the system. A rise of 1/4" per foot is the standard recommendation because it allows for adequate drainage without placing excessive strain on the piping or causing leaks. This angle helps maintain a clear pathway for exhaust gases to escape efficiently, thus optimizing the performance of the chimney system.

Choosing this rise also ensures that any buildup of moisture or residue can effectively flow towards the vent termination point. This is particularly important in systems that condense, as improper sloping could lead to water pooling within the tubing, which can create corrosion or blockages. Therefore, adhering to the 1/4" rise per foot standard supports both the operational longevity and safety of the chimney system.
