7. Instructions for authorized installer
gas fi red boiler (optional)
Read the instructions before installing and using the appliance.
This appliance can only be installed and used in permanently ventilated places according to UNI-
CIG 7129 and UNI-CIG 7131 Standards.
7.1 Connection to gas supply
Position the appliance as described in the Use and Maintenance Manual, remove the control panel as described
in the same handbook, and connect the appliance to the gas supply mains, or LPG bottle (G30/G31), using
rigid metal pipes or fl exible metal tubes according to UNI-CIG 9891 Standards. Check that the appliance is
prearranged for the type of gas actually being used; the corresponding setting is shown on the settings tag.
If the appliance is prearranged for a different type of gas, change the arrangement as described in the para-
graph “Changing the calibration”.
The gas infeed, consisting of an on-off valve (51), includes a G 1/8” threaded connection (thread is not gas tight)
according to ISO 228-1 Standard.
If using rigid metal pipes for connection to the gas supply, place an appropriate fi tting between the valve and
the rigid metal pipe, which should be provided with a G 1/8” female thread (thread is not gas-tight) accord ing
to ISO 228-1 Standard.
If using fl exible metal tubes for connection to the gas supply, interpose an appropriate G 1/2” female nipple
(gas-tight thread) according to ISO 7-1 Standard and a G 1/2” male nipple (thread is not gas-tight) according
to ISO 228-1 Standard; interpose a suitable gas-tight gasket.
When the connection is completed, open the gas fl ow upstream of the appliance and, using a soapy solu tion
(never a free fl ame), check the perfect tightness of the connection.
7.2 Venting the combustion fumes
In relation to the venting of the combustion fumes, the appliance is of Type A1: i.e., it draws in the air required
for combustion from the room and discharges the fumes in the same environment.
Place particular attention to the volume of the room where the appliance is to be installed: this should be at
least 12 m
3
.
If the room has a smaller volume, it will be necessary to install the appliance directly under a suction hood, and
also to provide a combustion air intake with a free-fl ow cross section of al least 100 cm
2
.
7.3 Ignition
Press and turn the gas valve knob (51) counterclockwise to the position of the fl ame symbol, as shown in Fig.
B. While holding the knob pressed, push a few times the burner ignition button, marked with the star symbol
(53) to ignite the burner (piezoelectric ignition).
When the fl ame is lit, check through the relative hole (54), while keeping the gas knob pressed for 5-10 sec-
onds. After this period, if the fl ame does not remain lit, repeat the ignition operation again.
7.4 Changing the calibration
The appliance is prearranged to operate with the gas indicated in the relative settings tag attached to the ap-
pliance. The information regarding the air setting, injector, rated and reduced heat fl ow are shown in Tables
1 and 2. The data that correspond with each model are indicated by the next-to-last character of the code for
the relative model. For example, the model code shown on the tag for the gas part characteristic 80-16M-3-G
shows number 3 in the next-to-last digit.
In this case, refer to the data shown in Tables 1 and 2, respectively, in the column headed “3 Units”. If
you wish to change the calibration of the appliance, proceed as follows:
Unscrew the primary air adjusting ring nut (55 - Fig. C) to expose the nozzle (56). Using the relative wrench,
unscrew the nozzle (56) and replace it with the proper one indicated in Table 2, checking that the diameter
marked on the same nozzle corresponds to the right diameter.
