APPLIANCE TYPE "B11"
• Fit the "B11" type appliance with a suitable flue, available
from the appliance manufacturer. Follow the assembly in-
structions provided with the flue.
• Connect the flue to a 150/155 mm diameter hose, heat resi
-
stant to 300°C.
• Vent to the outside or into an efficient flue. The hose length
must not exceed 3 metres.
11 CONNECTIONS
The position and dimensions of connections are given in the
installation diagram at the start of this manual.
CONNECTION TO THE GAS SUPPLY
Check the compatibility of the gas supply. Check the details
given on the decals on the packing and on the appliance. If
necessary, convert the appliance to the type of gas utilized.
Follow the instructions in the next paragraph "Conversion to a
different type of gas".
On top appliances a rear connection is also available. Remove
the plug present and screw it tightly onto the front connector.
• A rapid-action gas shut-off valve must be fitted upstream of
the appliance in an easily accessible position.
•
Do not use connection pipes having a diameter smaller than
that of the appliance's gas connector.
•
Once the appliance has been installed, check for leaks at the
connection points.
ELECTRICAL CONNECTIONS
Check that the appliance is designed to operate at the voltage
and frequency of the power supply present on site. Check the
details given on the appliance data plate.
If used, the symbol
indicates:
CAUTION - HAZARDOUS VOLTAGE.
•
Install an adequately rated omnipolar circuit-breaker upline
of the appliance in an easily accessible point, in compliance
with installation regulations; the circuit breaker must guaran-
tee immediate omnipolar disconnection from the mains, with
a minimum contact opening that allows complete disconnec-
tion in overvoltage category III conditions. The maximum per-
mitted current dispersion is 1mA/kW.
• For electrical connection, use a rubber-sheathed flexible ca
-
ble which is oil resistant, type H05RN-F or H07RN-F, for ca-
ble size consult the technical data table.
•
Connect the power supply cable to the terminal board as
shown in the wiring diagram supplied with the appliance.
•
Secure the power supply cable with the cable clamp.
•
Protect the power supply cable on the outside of the applian-
ce with a rigid plastic or metal pipe.
•
If the power supply cable is damaged, it must be replaced
by the manufacturer or the technical after-sales service or,
in any case, by a suitably qualified technician, so as to avoid
any risk whatsoever.
PROTECTIVE EARTH AND EARTH BONDING CONNEC-
TIONS
Connect the appliance to an efficient ground circuit. Connect
the earth conductor to the terminal with the symbol
loca-
ted next to the main terminal board.
Connect the metal structure of the appliance to the equipoten-
tial node. Connect the conductor to the terminal with the symbol
on the outside part of the bottom.
•
This symbol indicates that the appliance must be included in
an equipotential system connected in compliance with cur-
rent regulations.
12 CONVERSION TO A DIFFERENT TYPE OF GAS
Table T1 specifies, for each country:
•
which gas can be used for the appliance.
•
the nozzles and settings foreach gas that can be used.For
nozzles, the number indicated in table T1 is also stamped on
the nozzle body.
To convert the appliance to the local gas type, follow the in-
structions given in atable T1 and carry out the steps below:
•
Replace the main burner nozzle ( UM ).
•
Adjust the main burner's air regulator to distance A.
•
Replace the pilot burner nozzle ( UP ).
• Adjust the pilot burner air flow ( if necessary ).
•
Replace the gas valve minimum nozzle ( Um ).
• Affix the adhesive tab indicating the new type of gas used.The
nozzles and adhesive tabs are supplied with the appliance.
REPLACING THE MAIN BURNER NOZZLE AND ADJU-
STING THE PRIMARY AIR FLOW.
•
Slacken screw V.
• Remove nozzle UM (fitted to air regulator Z) and replace it
with the one indicated in table T1.
• Retighten nozzle UM (fitted to air regulator Z).
•
Adjust air regulator Z to distance A as shown in table T1.
•
Retighten screw V fully.
•
Re-assemble all parts. For assembly, proceed in reverse or-
der.
REPLACING THE PILOT BURNER NOZZLE
•
Undo connector R.
•
Remove nozzle UP and replace it with the one indicated in
table T1.
•
Retighten connector R.
•
Re-assemble all parts. For assembly, proceed in reverse or-
der.
CONVERSION TO A DIFFERENT TYPE OF GAS
MODELS --G420/820
Conversion from liquid gas to natural gas
After changing the main burner and pilot flame nozzles and
after adjusting the primary air (as shown in "Table
1
:
Specifications for the burners, nozzles and settings"):
•
loosen and remove the exclusion plug (item 1 in Fig.
C)
and replace it with the sleeve spring screw,
supplied with the nozzles, then tighten the screw
partially (item 1 in Fig.
F
);
