The shut-off valves in the T-piece should be opened as shortly as possible before the usage and they
should be closed again as fast as possible after the effects.
Before or respectively while putting the device into service it can be reasonable to check the whole
system with a gas leakage detector. If used on stages, buildings or tents this is absolutely necessary.
When screwing in the cartridges it can happen that a small amount of fuel is set free. Due to the fact
that gas leakage detectors are very sensitive you should wait some minutes so that the fuel that was
possibly released when the cartridge was installed can evaporate and volatilize completely. Then you
can begin with the testing against leakages.
If it should be the case that G-Flames do not ignite the aerosol spray or that there is a fuel leakage
because of a technical defect the units must be turned off immediately either by using the emergency-
off input or by deactivating the hazard zone that has been assigned to the device and the fuel supply
has to be terminated as fast as possible. The unit may only be turned off by using the main switch if
you can assure that there is no inflammable or explosible fuel-air ratio present. The advantage of
utilizing the emergency-off input is that during the shut-down no electric spark can be generated that
could ignite a fuel-air mixture.
Depending on your application it can be necessary to use gas detectors to ensure best possible
safety. In applications on stages, in buildings or tents this is mandatory. Cost effective devices are
offered on the market. Please note in this context that Propane and Butane is heavier than air and due
to that it can accumulate in sinks, trenches, cellars or shafts. This characteristic must be taken into
consideration when installing gas detectors.
Gas cartridges contain predominantly Butane, which has a lower vapor pressure compared to
Propane. Furthermore the vapor pressure curve of Butane has a much flatter characteristic. On the
other hand the cartridge is by far not so robust as a gas bottle. Therefore the maximum temperature,
which is 50 °C according to the guidelines provided by the manufacturers of the cartridges, must not
be exceeded during storage, transportation and usage.
The instructions in the material safety data sheet of the gas cartridges, the ADR regulations (i.e.
regulations for the transportation of dangerous goods) and the regulations imposed by the employer's
liability insurance association for the storage and usage of gas cartridges and all other relevant laws,
especially for places of public assembly, must be strictly followed. Especially the maximum allowable
temperature of the gas cartridges must not be exceeded. Protect the cartridges from direct sun light
and ensure that the cartridges do not become overheated e.g. if they are loaded on vehicles.
After each usage the remaining fuel in the T-piece and in the system of the G-Flame must be burned
off. To do so first close the shut-off valves on the T-piece and then initiate a flame effect several times
until no flame is being generated any more. Then the installation can be dismantled. In this context we
want to point out that it can take very long until the liquid fuel in the system has completely
evaporated. When the liquid fuel evaporates a lot of coldness is being generated (evaporation chill)
and this leads to a deceleration of the evaporation. Due to that it can absolutely happen that after a
certain time a flame is being generated again even though it seemed that the fuel evaporated
completely when emptying the system.
After emptying the system and burning off the fuel the installation can be dismantled. Before your
remove the T-piece you have to make sure that no ignition sources are present.
Attention! Expect that the G-Flame generates a flame every time you trigger the device even if there
is no fuel supply. It could be that there is still fuel in the system and due to that a flame can be possibly
generated. Furthermore it could be that the system has not been completely emptied last time when
the devices have been used.
