There are 3 different types of chimneys. In order
to select the the Draft Eliminator that will work most effectively
for you just refer to the 3 diagrams located on the right
side of this page. Once you have determined which
type of chimney you have, just follow the simple steps and
you will know exactly which product will work out best for
you.
Important Note: On any measured flue
opening smaller than 12" X 12" you should order a Draft
Eliminator within 3" of either dimension. On any measured
flue opening larger than 12" X 12" you should order a Draft
Eliminator within 6" of either dimension.
How to Choose the
correct size Chimney Balloon Draft Eliminator if there is no damper
(straight chimney with no closing mechanism) in
my chimney.
1) Before sizing your chimney
please make sure that your fireplace and chimney
are cold and that there are no embers that could
possibly harm you. If you sweep up your ash
or use an ash vac it will make the process much
cleaner. Never vacuum up hot ash!
2) Look into your chimney and find the narrowest
section within arms reach.
3) Select an area to install the Chimney
Balloon Draft Eliminator.
Make sure that there are no sharp edges or hardware
that may interfere with the installation.
The area must have parallel or slightly sloping
walls with significant texture to allow the balloon
to grab and lodge during inflation.
4) Measure the length and depth of the chimney
in the location you have selected to install a Draft
Eliminator. A very useful tool to measure
your chimney is a foldable carpenters ruler.
You can unfold this ruler into an L-shape to use
it as a ruler on a stick. If you do not have
a folding ruler, you can also use a tape measure.
5) Finally, go back to
Draft Eliminator page and select which of the
three will work best in your situation.
Example: Opening measures 6" wide X 9" deep.
You would go with a 12X12 Draft Eliminator.
How to choose the correct size Draft Eliminator
if there is a smoke shelf/chamber or if there is
a damper (metal flap closer) in my chimney.
1) Same directions as if you have no damper.
(See above)
2) Look into your chimney and identify the damper
(a metal flap with lever that closes the chimney)
if you have one. Then find the most narrow
section of your chimney above the damper, within
arms reach. This is where the Eliminator will
be located.
3) Select an area to install the Draft Eliminator.
Make sure that the area you select is not interfered
with by the damper flap or any hardware. The
area must have parallel or sloping walls with significant
texture for the balloon to grab and lodge during
inflation. Just above the damper is an ideal
location to install a Draft Eliminator. The
damper or smoke shelf (smoke chamber) acts as a
ledge to grant a little extra support to the weight
of it. A Draft Eliminator can also be installed
well above the damper, so it is possible to close
the damper below it.
4) Measure the length and depth of the chimney in the location you have selected
to install a Draft Eliminator. A very useful
tool to measure your chimney is a foldable carpenters
ruler. You can unfold this ruler into an L-shape
to use it as a ruler on a stick. If you do
not have a folding ruler, you can also use a tape
measure.
5) Finally, go back to
Draft Eliminator page and select which of the
three will work best in your situation.
Example: Opening measures 6" in diameter.
Then you would order a 9X9 Draft Eliminator.
