How do I reach and close the valve to my Chimney Balloon when i am installing it in my prefab fireplace?

Chimney Balloon Cropped

Q: Jason, I purchased two Chimney Balloons. I have two zero clearance fireplaces and there is no way to put the Chimney Balloon above the damper and still be able to reach the air valve. I am disappointed in this design. I can’t be the first person to have this problem, so please tell me how to make this work. – KB

A: Dear KB, I have a prefab zero clearance fireplace in my home just like yours. These fireplaces tend to have higher dampers and a higher location that is easy to put a Chimney Balloon in. This is the very reason we sell the HEK extender for the Chimney Balloon. If we just made the handle longer in the general design of the Chimney Balloon then it would be too long for most applications and it would make the Chimney Balloon more visible when installed. So the Chimney Balloon Handle valve HEK extender is the ticket for you to have an easier go of using your Chimney Balloon. – Jason

These high-up butterfly center pivot dampers are usually in prefabricated zero clearance fireplaces made by Heatelator.  Here are the characteristics:

  • The damper handle that opens the circular center pivot damper is usually on the outside lintel face of the fireplace.
  • You will notice that there are horizontal slats cut in the sheet metal just below the closed damper.

Those vent slats below the round damper gives you a pretty good place to tuck in a square Flueblocker. Measure the area below the damper (Image 1-3), and buy a Flueblocker that is a little larger than that area. Most of the time it requires a 12″x12″ Flueblocker, or a 16″x16″ trimmed down to fit. Just make sure you keep that pressure fit by having the pad be larger than the hole.

 

Because this install location is up out of reach, you will likely need to buy some extra 6″ Handle Extenders for your Flueblocker.
