Important instructions for propane appliances

Bleeding the liquid gas tank when installing the system:
before installing the device, make sure that the gas tank
has been bled. The liquid gas supplier is responsible for
the proper bleeding of the tank. Ignition problems can
be caused if the tank is not bled properly. In such cases,
first contact the person in charge of filling the tank.
Affixing the tank sticker:
Affix the enclosed tank sticker (propane quality) on the
tank where it is clearly visible or on the bottle cabinet, if
possible close to the filler nozzle.
Installing underground:
When installing in underground places, the requirements
of the TRF 1996 (technical rules for liquid gas) are to be
observed. We recommend the use of an external sole-
noid valve.
