guarantee.
3DESCRIPTION OF THE WATER HEATER
The water heater is composed from a water tank lodged over to
a combustion chamber where the heat necessary is developed in
order to heat the water.
The produced smoke therefore yields their heat to the water in
their fireplace towards the outside, passing through the tubes, the
exchanger dipped in the water.
On the high part a canopy collects the fumes from the exchanger and
drives them to the drainage system. A fan is situated in the upper
cap it, supplies the feeding of the air and the evacuation of the
products of combustion. The tank is constructed in sturdy sheet iron
and guarantees a remarkable resistance to pressure it’s moreover
glass lined at 860°. This concurs to obtain an optimal unassailable
chemical resistance (from organic solvent and from chemical
substances), an optimal thermal stability; the enamel resists until
500° The inner inspection and cleaning from the incrustations is
possible through the flange 120 mm diameter.
The combustion chamber is placed in the low part of the water
heater and it contains the atmospheric burner and flame probes.
Combustion chamber is completely sealed from the place where it
is installed.
Control Panel
The control panels contains all the components in order to adjust
the normal operation of the water heaters: thermostat, ignition
device, luminous release button, thermometer etc..
KIT OF SMOKE DRAINAGE (supplied separately)
As for the different requirements of Installation it can be:
• Concentric with drainage and aspiration to the wall
• Concentric with drainage and aspiration to the wall
• Divided with drainage and aspiration to the wall, to the roof or
in a fume pipe.
DESCRIPTION OF THE APPLIANCE 4TEST OF THE WATER HEATER AND SECURITY
Electronic ignition card
Fig. 02
It controls the opening of the gas valve and the burner ignition. Since
when it receives the electrical feeding from the thermostat it initially
checks that the contacts of the pressostat are in position of operation
otherwise there is no ignition; on the contrary, subsequently, it makes
a pre ventilation cycle of the combustion chamber and the ignition
spark, if during this cycle it does not find the flame of ignition in the
pre fixed time, it is placed in block position; in it this case please wait
some second and then press the luminous reset key.
The survey of the flame happens for ionization through appropriate
probe on the burner, CE Homologated EN 298.
GAS VALVE
It is made of one multifunctional multigas valve with double safety B class
for silent operation.
The valve is equipped of pressure regulator and device for the slow ignition,
with adjustable gas capacity (factory pre setted) Homologated as for norms
EN 126.
Fig. 03
The body is in fused aluminium it is supplied of inlet and outlet gas
connection 1/2”. The unit is supplied of inlet gas filter.
The two electro valves are connected in series on the main pipe of
the gas and are feeded by co a single tripolar connector, to avoid
wrong connections. All the operations of calibration and regulation
must be executed from qualified staff.
In case of replacement of the valve be sure that the flow of the gas
is in compliance with the arrow on the body of the valve and that
during the assembly operations external substances do not enter.
AIR PRESSOSTAT
Fig. 04
The function of this device is to control the combustion, interrupting
the operation of the burner in case of insufficient capacity of the
fan.
The device has 3 contacts,( two positions, one normally in open
position NA, the other normally closed NC.
MAGNESIUM ANODE
Magnesium anode is important to protect the water heater from
corrosion and galvanic currents. It is suggested to replace the anode
once every year, the anode is placed in the inspection flange, in the
frontal part of the tank.

Modification from LPG to methane
1. Verify that diameter of the injector supplied in the kit corresponds
to the model for LPG.
2. Close the gas interception tap and switch off the electricity.
3. Remove the burner unscrewing the fixing bolt A, unscrew before
the gas tube and disconnect the cables of the electrodes.
4. Unscrew the injectors B and replace them with the units inside the kit.
5. Rotating the RP screw adjust the pressure of the injector up to
the pressure for methane.
6. Switch on the generator and verify that injector pressure is right
for methane gas.
7. Place the new label on the body to indicate a different gas.
8. Verify with special spray the gas seal on the threads, gaskets etc.
16 CONNECTION WITH ELECTRICITY
The unit must be connected to single phase electric net plus a
ground; use a bipolar device near the unit.
THE MANUFACTURER IS NOT RESPONSIBLE FOR DAMAGES DUE
TO WRONG CONNECTION.
17
MORE UNIT CONNECTED TOGETHER
If more unit must be connected it is important that each one can
work singularly, all at the same time or only some units.
This is possible using some sluice taps in the hydraulic circuit in
order to decide the qty of unit that must use as for the required qty
of water; it’s suggested the following types of systems:

ANOMALOUS OPERATION
The control equipment goes in block without to command
to the ignition.
• The survey ame circuit is out of order and the auto check does not allow
the end of the cycle.
• The survey electrode ame has a dispersion .
At the end of the phase of pre ventilation the ignition
electrode does not make any spark and the equipment
goes in block.
• The ignition transformer is out of order, the connection of the
electrode of ignition with the card is interrupted.
At the end of the phase of pre ventilation the ignition
electrode makes spark, but the flame doesn’t take shape
and the apparatus goes in block.
• Lacks of gas power or is present air in the tubes.
• The valve of the gas does not open why the coils are out of order
or the electrical connection is interrupted.
At the end of the phase of pre ventilation the flame takes
shape but the apparatus goes in block.
• The flame is not become stabilized why the pressure is low.
• The electrode of survey of the gas is correctly placed and it is not

14 GAS CIRCUIT
Connect the gas with the threaded connection using a rigid
connector that can be disassembled.
Verify the seal that must be in compliance with the norms for gas
installations.
For installation with Lpg it is necessary to use a pressure reducer
(first stage) in proximity of the tank, in order to reduce the pressure
to 1,5 bars. In proximity of every generator must be used a pressure
reducer (second stage) in order to reduce the pressure to 29/37 to
mbarr.
