We often take it for granted though we know it isn’t true that flue gases will go up and out of the chimney though we know it isn’t always true. In this class we will explore the science of why and why flue gases exit chimneys. We will cover things like system design, house issues that affect our products negatively, external factors and solutions to venting problems.
