How do you open and close the chimney flue? You’ll typically find a handle or lever near the fireplace or stove to open and close a chimney flue. Push or pull the handle so the flue is upright and open, allowing smoke and gases to vent up the chimney. To close it, press or pull the handle in the opposite direction to seal off the flue, preventing drafts and outside air from entering. Make sure to check for proper positioning before starting a fire to ensure safety and efficiency in your fireplace or stove.
What Type of Damper Do You Have?
Throat Damper
A throat damper is a traditional damper located just above the firebox within the chimney’s throat. It is usually controlled by a lever or chain that can be accessed from the fireplace. Throat dampers are designed to open and close to regulate the airflow and prevent drafts when the fireplace is not in use. While they effectively block drafts, they are less airtight than top-mount dampers and can be less energy-efficient.
Top-Mount Damper
A top-mount damper, also known as a chimney cap damper, is situated at the top of the chimney, just above the flue. It is typically operated by a chain or cable that extends down the flue for easy access. Top-mount dampers are excellent for sealing the chimney when the fireplace is not in use, preventing drafts, and avoiding rain, debris, and pests. They are more energy-efficient and effective at maintaining an airtight seal than throat dampers.
How to Know if the Damper is Open
You can typically see or feel if the damper is open by looking into the fireplace or physically checking the damper’s position using a lever, chain, or handle provided for operation.
Feel for a Draft
One way to determine if the damper is open is to feel for a draft from the fireplace when the drag is in the open position. Place your hand near the fireplace opening and sense if air is flowing up the chimney. If you feel a draft, it indicates that the damper is open and allowing air to escape through the chimney.
Visually Check
You can visually inspect the damper’s position by looking up into the chimney from the fireplace. In most cases, you’ll be able to see the damper plate or door and whether it is in the open or closed position. Use a flashlight or a mirror to get a clear view of the damper, and ensure it is fully available if you intend to use the fireplace.
Check the Controls
If your damper is equipped with a control mechanism such as a lever, chain, or handle, check the position of these controls. If the lever or chain is horizontal or parallel to the fireplace opening, the damper is open. The damper is closed if it is in a vertical or perpendicular position. Checking the controls clearly indicates the damper’s status without the need for visual or tactile confirmation.
Do Not Start a Fire in the Fireplace if You Are Not Sure the Damper is Open
Starting a fire in the fireplace is crucial if you’re confident about the damper’s position. The damper plays a critical role in venting smoke and gases safely up the chimney. Lightning, a fire with the damper closed, can lead to smoke filling your living space, causing potential health hazards and damage. Always double-check and ensure the damper is fully open before starting a fire to guarantee safe and efficient use of your fireplace.
How to Check the Controls and Open a Damper
How to check the controls
Checking the controls for your fireplace damper involves visually inspecting the lever, chain, or handle’s position. If a lever controls the damper, ensure it is in a horizontal or parallel position to the fireplace opening, indicating that the damper is open. If your damper is operated with a chain or handle, confirm that it is in a downward, hanging position when available and in a raised or upright place when it is closed. By verifying the alignment of these controls, you can quickly determine whether the damper is open or closed and make the necessary adjustments for safe fireplace use.
How to Open a Damper
To open a fireplace damper, locate the control mechanism, often a lever, chain, or handle, usually found within or near the fireplace. If you have a lever, push or pull it to the parallel or horizontal position, which signifies that the damper is open. For a chain or handle, pull it downward, ensuring the damper plate or door is fully upright. Double-check the damper’s position visually to ensure it’s open, essential for proper ventilation when using the fireplace.
Different Types of Controls
Fireplace dampers can be controlled using various mechanisms:
- Lever: A lever is a standard control for fireplace dampers. You can move it to a horizontal or parallel position to open the damper and a vertical or perpendicular position to close it.
- Chain: Some dampers have a chain control. Pulling the chain downward typically opens the damper, while letting it hang indicates an open damper. Raising the chain signifies that the damper is closed.
- Handle: Dampers with a handle function similar to chains. Pull the handle down to open the damper and push it up to close it.
- Rotary Control: Modern fireplaces have rotary-style controls that adjust the damper’s position easily.
- Remote Control: Remote-controlled dampers are available, providing the convenience of opening and closing the damper from a distance.
- Automated Systems: Smart or automated fireplace systems can control the damper, allowing for easy adjustments via smartphone apps or other digital interfaces. These systems can provide precise control and scheduling options.
The specific control type will depend on your fireplace design and technology level.
FAQs about How do you open and close the chimney flue?
Q: What is a chimney flue, and why must it be opened or closed?
A chimney flue is a passageway within the chimney that allows smoke, gases, and air to travel safely outside. Opening and closing the flue is necessary to control a fireplace or stove’s airflow, draft, and heat retention.
Q: How do I know if my chimney flue is open or closed?
You can typically see or feel the flue’s position by looking into the fireplace or checking the control mechanism. A horizontal lever, a hanging chain, or a downward handle usually indicates an open flue. In contrast, a vertical lever, a raised chain, or an upward handle means a closed flue.
Q: When should I open the chimney flue?
Open the flue before starting a fire in the fireplace or using a wood-burning stove to allow smoke and gases to escape safely. Keep it open while the fire is burning and for some time afterward to ensure proper ventilation.
Q: When should I close the chimney flue?
Close the flue when the fire is entirely out to prevent drafts, heat loss, and rain or animal entry into the chimney. Also, always keep the flue closed when the fireplace is not used.
Q: Are there different types of flue controls?
Yes, there are various control mechanisms, including levers, chains, handles, rotary controls, remote-controlled options, and even automated systems, depending on the fireplace or stove design and technology level.
Q: What precautions should I take when operating the flue controls?
Be gentle when moving the controls to avoid damage. Double-check the flue’s position visually after adjusting the rules to ensure it’s open or closed as needed. Only start a fire if you know the flue’s status; safety is a top priority.
