Make sure the appliance corresponds with the gas
supply to which it is connected. If it does not,
convert as instructed in the section "Adaptation to
different type of gas".
Once the appliance has been installed, cheek for
gas leaks at the connection points.
All pieces needed for montage will be supplied by
manufacturing company.
Gas flex and gas hose connections must be carried
out in accordance with TS EN 14800 standard.
Electrical connections
The appliance is designed to operate at the
voltage indicated on the data plate.
Each appliance must be connected to the power
supply by a suitably dimensioned independent
line (the total power is indicated in the "T1"
table). A flexible rubber cable with insulation
specifications not lower than type H 07 RN-F
must be used for connection to the temiinals.
The length of conductors between the cable clamp
and terminals must be such that the live wires are
pulled taut before the ground wire (yellow-green)
if the cable is worked loose from the clamp.
Multi-pole main isolating switches of suitable
current ratin. (with minimum contact-breaking
distance of 3 mm) must be installed, as well as
automatic residual current switches of suitable
high sensitivity.
There should be a automate fuse between the
appliance and the network.
Voltage changes should not exceed %10V.
Ground connections and equipotential bonding
The appliance must be connected to the ground
circuit using the terminals marked by the symbol
located next to the connection terminals.
The metal structure of all the electrical appliances
must also be connected to the ground circuit using
the terminals marked by the symbol
located next to the earth terminals (equipotential
bonding system).
If, frequency inventor is being used in the equipment,
TYPE B RCD (residual current relay) with AC/DC
sensitivity must be used before the equipment power
inlet (from the mains block terminals).
Water connection
Install a fast closing stopcock in an easily
accessible position upline from the appliance.
There must be a mechanic filter between the valve
and the appliance. The dirt and the metal particles
which oxidize the interior surface of the appliance
are hold by the filter.
Before connecting the last pipe, the dirt should be
discharged by means of water flow and then the
connection should be done.
Confirm the absence of leaks at the connections.
The control knob for the supply of water is on the
front of the appliance.
The water supply pressure must be between 150
and 250 kPa.
ADAPTATION TO DIFFERENT TYPE
OF GAS
The appliance has been adjusted to operate with
20mbar NG(G20). To convert the appliance to a
different gas supply, scrupulously follow the
instructions indicated below.
Use the injectors and adhesive labels in the bag
supplied with the appliance.
Replacement of main burner injector
(Fig.1)
Remove the control panel from the appliance.
Unscrew the injector “1” from injector connection
part “5”.
Choose a suitable injector indicated in table “T2”.
Screw the new injector to injector connection part
“5”.
Replacement of pilot burner injector
(Fig.2)
Remove the control panel from the appliance.
Unscrew fitting “A” and replace injector “B” with
the one indicated in Table “T2”.
Retighten fitting “A”.
WARNING : If the appliance is converted to a
different gas supply, affix the correct adhesive tag
indicating the new gas used.
START UP
Control of operation of gas devices
Operate the appliance according to the instruction
manual and check the correct lighting of the
burners, the absence of gas leaks and the
efficiency of the waste gas removal system.
If necessary consult the paragraph on "Typical
malfunctions".
Control of operation of electrical devices
Operate the burners according to the instruction
manual, cheek the correct functioning of the
controls and of the safety devices:
Operating thermostat: Cheek the heating
regulation at various temperatures.
