Functions of the Lever on the Side of Your Fireplace

The lever located on the side of your fireplace typically serves a functional role in controlling various aspects of the fireplace’s operation. Its specific purpose can vary depending on the type and design of the fireplace, but generally, it is involved in one or more of the following functions:

  • Airflow Regulation: Many fireplaces use a lever to adjust the amount of air entering the combustion chamber. Controlling airflow helps regulate the intensity of the fire and the rate at which fuel burns. Opening the lever allows more oxygen in, making the fire burn hotter and faster, while closing it reduces oxygen flow, slowing combustion.
  • Damper Control: In traditional wood-burning fireplaces, the lever often controls the damper—a movable plate inside the chimney. The damper can be opened to allow smoke and gases to escape when the fire is burning, or closed when the fireplace is not in use to prevent heat loss and keep drafts out.
  • Gas Valve Operation: On gas fireplaces, the lever may function as a manual control for the gas valve, turning the gas flow on or off or adjusting the flame height.
  • Ash Drawer or Grate Adjustment: In some designs, the lever may operate an ash drawer or move a grate to facilitate easier cleaning or to adjust the positioning of burning logs for better combustion.

Understanding the role of this lever is crucial for safe and efficient fireplace operation, as improper use can lead to smoke backdrafts, inefficient burning, or safety hazards.

How to Identify the Purpose of Your Fireplace Lever
