SPARK® (CHILDPROOF DISPOSABLE LIGHTERS)

Spark child proof disposable lighters are constructed so that a child cannot light the lighter. The lighter will not ignite accidentally.

1. The spark actuation roller will spin around away from the flint unless a force is applied downward so that friction is applied to the centre of the roller.

2. After this action the gas release button can be pressed to release the gas.

3. The gas will be ignited by a spark generated from the flint.

The above actions must occur in the order stated above for the lighter to light.

The Spark ® lighter is made up of the following components:

a) The gas reservoir with a centre stiffening brace joining both side walls of the reservoir. The maximum volume of liquid allowed in the chamber is 85% of the total chamber volume.

b) Gas release valve. This valve is sprung loaded so that it re-seals itself after the release button is released.

c) A flame height adjuster which when turned adjusts the height of the flame. On our Spark Lighters turning the Flame Height Adjuster clockwise lowers the flame and anticlockwise increases the flame height.

d) Gas exit nozzle. This nozzle allows gas to exit the reservoir and mix with air after it has left the chamber. This is termed "a post mixing burner".

e) A Flint and a Spark Actuation Roller. These two components are used together to cause a spark which ignites the gas vapour released from the nozzle. The flint is permanently pushed upwards on to the roller using a spring. The centre of the roller is very coarse and causes friction on the flint. This generates a spark.

f) The Upper Lighter Body is bonded on to the gas reservoir in such a way to form a sealed chamber where the propane gas can be stored as a liquid under pressure.

g) The Flame Shield protects the nozzle and the working mechanisms of the flame adjuster and valve. It also allows the gas to liquefy completely and mix with air so that a "non-sputtering" flame occurs.

Liquid Propane Gas

Propane gas is normally a vapour under normal atmospheric pressure. It has to be pressurised to convert to a liquid form of the gas. The volume of vapour formed from the liquid is 22.6 times the volume of liquid.

Liquid propane converts instantaneously to propane vapour when released from pressure. The efficiency of our Spark lighter is governed by the inner tube dimension of the gas exit nozzle. Too big a nozzle will use up propane gas quickly and will cause a flame that is too big in diameter for the lighter safety. Too small a nozzle will cause the flame to be very high and be unsafe for normal use.

SAFETY FEATURES OF SPARK ® CHILD PROOF DISPOSABLE LIGHTERS

1. The lighters are child proof. A child cannot light them

2. There are no sharp edges on the lighter.

3. The flame height is adjustable so that it can be used to a personal setting. The maximum setting (set by the manufacturer) will never give a flame height greater than 120 mm.

4. The flame will extinguish itself immediately the gas release button is released.

5. All the components of the lighter are compatible with the propane gas in the liquid or vapour form. This means that there will not be any corrosion or softening of the lighter components during storage or use.

6. Spark lighters have been tested under BS EN ISO 9994:2002 standards.

Do not puncture or incinerate
Ensure the flame is extinguished after use
Keep away from children
