ed when lit.

or other imperfections.

for a long time or in case of transport by a motor ve-
hicle, unscrew the cylinders and the cartridges from
the respective pressure reducer and gas valve. This

even much time later, avoiding the possibility of little
and almost imperceptible leaks, even though all their
valves are provided with guaranteed seal.

packaging (if possible in the original one) and keep it
in a cool, dry and well ventilated place.
