I can’t close my damper because of a clip-on damper restrictor

I can’t close my damper because of a clip-on damper restrictor

"round damper with restrictor clip holding damper flue open"Q: I went to install my chimney balloon over my gas log fireplace and I found a clip that was holding my fireplace damper open. I removed it and now the damper works fine.

A: The clip you found was a damper restrictor. However keep in mind that it is against most state codes to have a gas log fireplace without a damper restrictor in place. I would check with your county before you go and seal up with your metal damper. This is an issue that can void some home owners insurances, so it is very important to stay within this code if it applies to your state.

The reason for this code is gas logs burn very clean and you can easily start a fire in the fireplace and forget to open the damper for quite some time while the fire burns on…This creates a buildup of carbon monoxide and heat that can start a fire (starting with your mantel) or the carbon Monoxide can overcome you and others in your home. The downside of this code is that having a damper restrictor on your damper is like having a window cracked open all year round.

If I were you I would call the County Building Code Office or call a fireplace retailer and ask them first about the codes in your area.

Fireplace #103: Plugging the Chimney At the Top

Installing any of our chimney plug products at the top of the chimney is definitely an “off label” use. It is not something we promote at all, because of the dangers of putting a plug at the top of the chimney. That said, we always get people asking about it, so it is important to discuss.

Here are the situations where you should NEVER put a plug at the top of your chimney:

  • If you have a vented or vent-less gas log.
  • If you have a gas assist fire starter.
  • If you have fires in the fireplace at all.
  • If you think someone else may possibly have a fire the fireplace.
  • If you don’t have the equipment or good-sense to get to your chimney top safely.

Here are the decent reasons to consider plugging a chimney at the top:

  • If you have a fireplace that is completely out of commission for structural or safety reasons.
  • You have an electric fireplace insert, a TV, an aquarium, or some other large item occupying the firebox.
  • If you NEVER ever have fires, and you don’t own any matches, lighters, flint and steel, or other fire making devices.
  • If every visitor you have to your house has the good sense to not use your fireplace.
  • If you don’t mind a large red sign in your firebox that reads “STOP! This chimney is plugged at the top!”

If you do decide to plug the chimney at the top, you still need a chimney cap or cover of some kind, so the chimney plug is not hanging out uncovered in the elements.  You can even make a plywood cover with a counterweight (image 103-2 and 103-1).

Whether you decide to use a Flueblocker or Chimney Balloon you should take a short bit of twine or cord and tie the chimney plug handle to the chimney cap or cover. This way if a lightening strike or squirrel incursion destroys the plug, it wont fall down the chimney and get stuck half way.
