INSTRUCTIONS FOR THE INSTALLER
If there are other fuel burning appliances in the
same room BS 5440: Part 2:1989 should be
consulted to determine the air vent requirements.
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 still metal pipes or fl exible
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 connection in compliance with
the regulations and provisions of the law. Grounding
is compulsory.
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 characteris-
tics” 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.
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 C 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 propane 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
x0.75mm 2 , type H05VV-F or H05RR-F, complying
with the regulations in force.
The connection to the terminal board must be
effected as shown in fig. 10:
