Chimney Balloon is a 9 x 9 Chimney balloon inside of a 9-inch round tube.
You attach the inflation tube to the bottom and then prepare the material by pulling up on the white cap and stretching the sides. After you do the your measurement that means you would use a 9×9 Chimney Balloon.
Take out one Chimney Balloon out of the package and connect up the inflat tube and then prepare the Chimney Balloon by grabbing hold of the white cap on top pulling the chimney balloon up and scrunching in the side.
When you have the blue wadded up in one hand, we can go into the chimney and tuck it past the flue damper. Take the Chimney Balloon and put it in past the flue and then put a couple of puffs of air into it it and close the valve.
If you need to remove the Chimney Balloon, open up the valve and it will start relaxing. Crumple up and bring it down.
