What is That Lever on the Side of My Fireplace? A Comprehensive Guide

Many fireplace owners encounter a mysterious lever on the side of their unit and wonder about its purpose. This lever isn't just a decorative element; it plays a crucial role in your fireplace's functionality and safety. This comprehensive guide will explain what this lever does, its different types, troubleshooting common issues, and when to call a professional.

Understanding the Fireplace Lever: Its Purpose and Function

That lever on the side of your fireplace is usually a damper control. The damper is a vital component located within your fireplace's chimney. Its primary function is to regulate the airflow into and out of the firebox. This control over airflow directly impacts:

• Draft control: The damper adjusts the draft, influencing how efficiently your fireplace burns. A properly adjusted damper ensures a clean, consistent burn with optimal heat output.
• Smoke evacuation: The damper prevents smoke from backdrafting into your home when the fireplace is not in use. A closed damper seals the chimney, keeping smoke and other combustion byproducts contained.
• Energy efficiency: A correctly functioning damper improves the efficiency of your fireplace by preventing heat loss up the chimney when not actively burning a fire.

Types of Fireplace Dampers and Their Corresponding Levers

Different fireplaces utilize various damper mechanisms, each with its own lever design and operation:

1. Manual Dampers with a Lever

This is the most common type. A simple lever, often located on the side or front of the fireplace, directly controls the damper's position – open for burning and closed for non-use. These levers usually operate a simple metal plate or a more complex system of linkages.

2. Top-Mounted Dampers (Less Common)

Some fireplaces have a damper located at the top of the chimney. These are less accessible and may require specialized tools or techniques for adjustment. Accessing these may require removing parts of the fireplace surround.

3. Automatic Dampers (Modern Fireplaces)

Modern, high-efficiency fireplaces often incorporate automatic dampers controlled electronically or by a thermostat. These typically don't have a visible lever for manual control; instead, they are integrated into the fireplace's control system.

Troubleshooting Common Issues with Your Fireplace Lever

If your fireplace lever seems stiff, unresponsive, or causes issues with smoke, several problems could be at play:

• Stuck damper: The damper itself might be stuck due to rust, debris, or warping. This requires careful cleaning or potential replacement. Never force a stuck damper.
• Damaged linkage: The mechanical linkage connecting the lever to the damper can break or become dislodged. This typically requires repair or replacement.
• Improper installation: If the fireplace is new or recently installed, a fault in the installation may cause damper malfunction.

When to Call a Professional

If you're unable to resolve the issue yourself, or if you're uncomfortable working with your fireplace's mechanisms, contact a certified chimney sweep or fireplace professional. They have the expertise and tools to diagnose and repair any problems safely and effectively.
