Draft Hood
A Draft Hood is a common safety device found in heating systems, particularly on water heaters and furnaces. It's like a protective cap that sits on top of heating equipment and helps manage how gases flow out of the system. Think of it as a traffic controller that makes sure dangerous gases go up the chimney instead of into living spaces. When someone mentions experience with Draft Hoods on their resume, they're typically talking about installing, inspecting, or maintaining these important safety components. Similar terms you might see include vent hood, flue damper, or draft diverter.
