Overview
In this class, we will delve into the science behind how and why flue gases exit chimneys. Topics will include system design, common house-related factors that negatively impact venting, external influences, and solutions to venting challenges.

This course aims to clarify the connection between the pressures within a chimney that generate "Draft and Flow" and how they are influenced by the pressures inside the house and the external atmosphere. We will explore the house as a system, focusing on how and why air moves in and out of the building envelope.
