How to Measure Your Chimney and install your chimney balloon

For your chimney balloon to work effectively, it is crucial that you install it properly. Here is a summary of the main points to bear in mind:

Measure your chimney about a foot or so up the chimney flue.

You will need the side-to-side and the front-to-back measurements (remember, these are taken inside the chimney, up out of sight).

We suggest you use a flexible steel tape measure (Stanley type) or two pieces of wood or cardboard extended like wings. It is only necessary to measure approximately and choose the Chimney Balloon of the appropriate size or slightly larger than your chimney. You may find it easier to measure middle to left side then middle to right side, and add them together to get the full width.

At a push you can even just count the bricks inside - allow 9 inches per brick length.
