INSTRUCTIONS FOR THE INSTALLER
Gas connection
Make sure that the appliance is adjusted for
the gas type available (see the label under the
appliance). Follow the instructions indicated in the
chapter "gas transformations and adjustments" for
the possible adaptation to different gases.
The appliance must be connected to the gas
system by means of stiff metal pipes or flexible
steel pipes having continuous walls, in compliance
with the regulations in force.
Some models are equipped with both cylindrical
A and conical B connectors for gas supply (fig. 7).
Please select the type which is correct for the
supply concerned.
The connection must not stress the gas ramp.
Once the installation is over, check the
connection seal with a soapy solution.
Electric connection
The connection to the electric grid must be carried
out by qualified personnel and in conformity with
the regulations in force.
The voltage of the electric system must correspond
to the value indicated in the label under the
appliance. Make sure that the electric system is
provided with an effective ground connction in
compliance with the regulations and provisions of
the law.
Grounding is compulsory.
This device must be at a suitable opening distance
from the contacts in order to allow the entire
disconnection in case of overvoltage category III,
in accordance with installation rules.
GAS TRANSFORMATIONS AND ADJUSTMENTS
Replacing the nozzles
If the equipment is adjusted for a type of gas that is
different from the one available, it is necessary to
replace the burner nozzles.
The choice of the nozzles to replace must be
made according to the table of the "technical
characteristics" as enclosed.
Act as follows:
- Remove the racks and burners.
- By means of a straight spanner L, unscrew
the nozzle U (fig.8) and substitute it with the
corresponding one.
- Tighten the nozzle strongly.
The manufacturing firm refuses all responsibility for any possible imprecision in this booklet, due to misprints or
clerical errors. It reserves the right to make all the changes that it will consider necessary in its own products,
without effecting the essential characteristics of functionality and safety.
Adjusting the burners
The lowest flame point must always be properly
adjusted and the flame must remain on even if
there is an abrupt shift from the maximum to the
minimum position.
If this is not so, it is necessary to adjust the lowest
flame point as follows:
- start the burner up
- turn the tap up to the minimum position (small
flame)
- remove the knob from the tap rod
- introduce a flat-tip screwdriver in the hole F of
the tap (fig. 9) and turn the by-pass screw up to a
proper adjustment of the lowest flame point.
As regards G30 gas burners, the by-pass screw
must be tightened completely.
MAINTENANCE
Replacing the power supply cable
If the power supply cable should be replaced,
it is necessary to use a cable with a section of
2
3x0.75mm , type HO5VV-F or H05RR-F, complying
with the regulations in force.
The connection to the terminal board must be
effected as shown in fig. 10 - 10/A:
brown cable L
blue cable N
