Rigid connection:
Carry out connection by using metal rig-
id pipes (copper with mechanical end).
"Flexible" connection with
mechanical end:
– Natural gas: connection carry out with
a flexible pipe with mechanical end
which is screwed directly on the elbow
finishing the slope of the appliance.
– Butane / Propane: use a flexible tube,
equipped with it's collars if it is worth
visiting over all it's length and if the
appliance runs only on butane. If the
appliance runs on Propane, use a flexi-
ble pipe with suitable metal end.
Flexible nonmetal pipes
connection:
If it is possible to easily control the con-
nection in its full area, you can use a flex-
ible pipe. Tightly attach the flexible pipe
by clamps.
Liquid gas: use the rubber pipe holder.
Always engage the gasket. Then contin-
ue 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
check its condition.
The control of preservation of the flexi-
ble pipe consists in checking that:
B C
– 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!
8.2 Injectors replacement
1.
Remove the pan supports.
2.
Remove the caps and crowns of the
burner.
3.
With a socket spanner 7 remove the
injectors and replace them with the
ones which are necessary for the
type of gas you use (see table in
"Technical Information" chapter).
4.
Assemble the parts, follow the same
procedure backwards.
5.
Replace the rating plate (it is near
the gas supply pipe) with the one for
the new type of gas supply. You can
find this plate in the package sup-
plied with the appliance.
If the supply gas pressure is changeable
or different from the necessary pressure,
you must fit an applicable pressure ad-
juster on the gas supply pipe.
8.3 Adjustment of minimum
level
To adjust the minimum level of the burn-
ers:
1.
Light the burner.
2.
Turn the knob on the minimum posi-
