Positioning
& Measuring Up
Chimney
balloons are simple to install and can be fitted by
anyone in a couple of
minutes.

Positioning:-
Normally, the chimney balloon goes about 1 to 2 feet
above the fireplace opening, depending on your type of
chimney and on the size of your chimney balloon. The
smallest parallel section is the best position, as long
as most of the handgrip is obscured and the chimney
balloon fits snugly all round. It must not fret or rub
once installed.
Measure
Up:-
Once you have decided the best position to
site your chimney balloon, simply measure the
width and depth of your chimney at that
position. Please remember that all sizes shown
are chimney sizes and not chimney balloon
sizes. The balloon will always be slightly
larger to allow it to hold in place.
Ventilation:-
The chimney balloon is designed with a curve
at one end to allow for a little ventilation,
which is required to prevent the build up of
condensation within your chimney stack and
your wall. Should your balloon be too large,
then the inbuilt curve will not be effective,
as the balloon will not be able to be fully
inflated. You can improvise in this case by
using a plastic tube (of about 50mm diameter),
and wedging it between the chimney stack and
the balloon. Please place the tube in position
before fully inflating your balloon.
Installation:-
With the tap open (in line with the handgrip), blow a
little air in to the chimney balloon - just enough to let you place it up into position without it scraping
against the chimney. If you have a cast iron fire with a
hole for the smoke to rise through you will need to push
the chimney balloon through this before you start
inflating.
With the chimney balloon in place and the
white label facing you, complete inflation:
|

|
- by mouth inflation tube, plugging directly into
the tap
- by air bed pump, inserting the nozzle into the
tube end
- by mountain bike or car valve pump, inserting
the flexible connector end in to the rubber tube end.
|
When inflated, turn the tap off. You may have to top it
up in an hour or two because the air may have cooled.
Check while you are inflating it that the chimney
balloon is positioning correctly - it may find its own position because it tends to move to where the chimney
is widest. Continue until the balloon is gently firm,
like prodding your thigh, but not drum-taut. You can
test it by pushing the handgrip upwards - it should feel
springy. The handgrip must hang free without restraint.
Put the "remember" notice in the grate or by
the gas tap. If winds cause high chimney suction, tether
the chimney balloon by its tap to the grate with a
length of string. If you are leaving the chimney balloon
permanently in position, check every 3 months that it is
still doing its job. You may very occasionally need to
top up the air.
Removal:-
Remove the "remember" card, then open the tap.
Press the handgrip against the side of the chimney
through the balloon, so that the air is forced out. Soon
you will be able to pull the balloon free. Roll it in
newspaper or a polythene bag for tidy storage.
Repair:-
Wipe
abrasion holes clean and seal with Sellotape
Safety:-
If a
fire is lit with the balloon in place, it will quickly
shrink, allowing fumes to escape up the chimney. The bag
is unlikely to burn if it remains in the chimney and the
handgrip is made from non-combustible plastic.
Caution:-
If
you over-inflate your chimney balloon, the inflator will
probably blow out before the bag bursts,
but we cannot
accept responsibility for any damage howsoever caused,
except as covered by the Sale of Goods Act.
