Closing the Flue on a Fireplace: A Step-by-Step Guide

A fireplace can be a cozy and inviting feature in your home, but it’s important to know how to operate it safely. One crucial aspect of fireplace safety is knowing how to properly close the flue. This simple act prevents unwanted drafts, helps retain heat, and ensures your home remains safe and comfortable.

Why is Closing the Flue Important?

• Prevents Drafts: When the flue is open, it allows cold air to enter your home, making it feel chilly and uncomfortable. Closing the flue prevents this, keeping your living space warm and cozy.
• Prevents Heat Loss: An open flue acts like a chimney, allowing precious heat to escape your home. Closing the flue helps retain heat, making your heating system more efficient.
• Ensures Safety: An open flue can be a safety hazard, particularly during inclement weather. Strong winds can create downdrafts, potentially bringing smoke, debris, or even animals into your home. Closing the flue eliminates this risk.

Steps to Closing the Flue on a Fireplace

1. Extinguish the Fire: Ensure the fire is completely extinguished before proceeding. Ashes should be cool to the touch. 2. Inspect the Damper: The damper is the metal plate that controls the flue opening. Locate the damper handle, which is usually found near the top of the fireplace. 3. Close the Damper: Pull the damper handle down until it fully closes the flue. This will create a tight seal, preventing any air from passing through. 4. Test for Airtightness: Once the damper is closed, light a candle or incense near the fireplace opening. If you see smoke or smell the scent, the damper is not fully sealed. Adjust it further until there is no evidence of air flow.

Types of Damper Systems

• Manual Damper: These are the most common type and are operated by a handle that you pull down to close the flue.
• Automatic Damper: These dampers are typically controlled by a thermostat and automatically open and close based on the temperature in the room.
• Top-Sealing Damper: These dampers seal the flue from the top, preventing drafts and heat loss more effectively than traditional dampers.

Note: If your fireplace has a glass door, make sure it is also closed when the flue is closed.

When to Close the Flue

• After Use: Always close the flue immediately after using the fireplace.
• When Not in Use: Even if you’re not using the fireplace, you should close the flue during colder months to prevent drafts and heat loss.
• Before Leaving the Home: Close the flue before leaving your home, even for short periods.

Remember: Regularly inspect your fireplace and damper for any signs of damage or wear. Contact a professional for repairs if necessary.

Final Thoughts

Closing the flue on your fireplace is a simple yet important safety and efficiency measure. By following the steps outlined above, you can ensure your fireplace operates safely and efficiently, keeping your home warm and cozy throughout the year.
