Flue
A flue is a pipe, duct, or chimney that safely carries exhaust gases from heating systems, fireplaces, or other fuel-burning appliances out of buildings. It's a crucial safety component that ensures harmful gases like carbon monoxide are properly vented outside. When candidates mention flue work on their resumes, they're typically referring to installing, maintaining, repairing, or inspecting these ventilation systems. This is an essential skill for heating technicians, HVAC professionals, and chimney specialists.
