Liquid gas
Use the rubber pipe holder for liquid
gas. Always engage the gasket. Then
continue with the gas connection.
The flexible pipe is prepared for apply
when:
– it can not get hot more than room
temperature, higher than 30°C;
– it is no longer than 1500 mm;
– it shows no throttles;
– it is not subject to traction or torsion;
– it does not get in touch with cutting
edges or corners;
– it can be easily examined in order to
make sure its condition.
The control of preservation of the flexi-
ble pipe consists in checking that:
– it does not show cracks, cuts, marks of
burnings on the two ends and on its
full length;
– the material is not hardened, but
shows its correct elasticity;
– the fastening clamps are not rusted;
– expired term is not due.
If one or more defects are visible, do not
repair the pipe, but replace it.
When installation is complete,
make sure that the seal of each
pipe fitting is correct. Use a
soapy solution,
not a flame
!
