A: JC, I know it is tempting for you to think we recommend a lower install location because we are just trying to sell a larger more expensive Chimney Balloon. But that is not why we suggest this. There are a number of reasons why you should install a Chimney Balloon in a lower location. Here are a few:
It is best to install a Chimney Balloon in an area that you can reach with your hand because it will be easier to install and uninstall. When installing the Chimney Balloon you may need to prod a corner into place or adjust the alignment of the Chimney Balloon with your hand, and this is easier to do if the Chimney Balloon is installed in an easy to reach location. We make handle valve extenders for the Chimney Balloon in case it is not possible to install in an easy to reach location.
If you install a Chimney Balloon low down you will be sealing off more of the fireplace inner chimney surface from your home. There are two advantages to this. If the creosote of your fireplace is particularly smelly or humid this isolates your home air from being contaminated by the chimneys smoky creosote smell. The other advantage is that heated air in a fireplace chimney tends to naturally cool and sink and create a draft sensation (Here is an article that addresses problems with top sealing dampers that tend to not stop the chimney draft)
The damper photo image above is a perfect example. The fireplace owner told us the chimney area is humid and sooty and smelly and the damper leaked cold air. We recommended a Chimney Balloon to be installed just above the damper, nice and low. After the customer installed the properly sized Chimney Balloon and used vinegar to neutralize the smokey aroma, the stinky fireplace smell stopped for good. – Jason
