In the event of faults and/or malfunctions,
GENERAL SAFETY INSTRUCTIONS
switch the appliance o and shut o the
gas valve. Do not attempt to perform any
repairs yourself but contact a qualified pro-
fessional instead.
Any repairs must be carried out by quali-
fied technicians using original spare parts
only. Failure to comply with the above may
jeopardise the device’s safety and void the
manufacturer’s liability.
In the event of any maintenance or other
work on structures in the immediate vicini-
ty of the ducts or flue gas discharge devic-
es and relevant accessories, turn the ap-
pliance o and on completion of the work,
have the eciency of the relative ducts or
devices checked by a qualified profession-
al.
5. Keep all packaging material (clips, plastic
bags, expanded polystyrene, etc.) out of
reach of children, as it may be potentially
dangerous.
6. The appliance can be used by children
older than 8 years and by people with re-
duced physical, sensory or mental abilities,
or who lack adequate experience and the
necessary knowledge, provided they are
supervised or have been instructed on the
safe use of the appliance and on the po-
tential risks connected with it.
Children must not play with the appliance.
Any cleaning and maintenance performed
by the user must not be eected by unsu-
pervised children.
7. It is mandatory to fit a regulatory safe-
ty valve onto the appliance’s water inlet
pipe. For countries that have implemented
standard EN 1487, the safety unit must have
a maximum pressure of 0.7 MPa and must
include at least a shut-o valve, a check
valve, a safety valve and a water pressure
shut-o device.
8. The pressure safety device (safety valve or
unit) must not be tampered with and must
be operated regularly to verify that it is not
clogged and to remove any limescale de-
posits.

GB
9. It is normal that the safety unit drip when
water is being heated. For this reason the
drain outlet must be connected and always
left open to the atmosphere, with a con-
tinuously downward-sloping drainage pipe
installed in a location which is not subject
to icy conditions.
10. The appliance must be drained and dis-
connected from the mains if it is to be left
inactive in a room subject to frost.
11. Hot water running from taps at tempera-
tures above 50°C may immediately cause
serious burns. Children, the disabled and
the elderly run a greater risk in this regard.
It is therefore advisable to use a thermo-
static mixing valve connected to the appli-
ance’s water outlet pipe (which is identified
by a red collar).
12. No flammable items should be left in con-
tact with or in the vicinity of the appliance.
13. Do not stand under the appliance or place
anything under it that may be damaged by
water leaks, for instance.
14. Do not use insecticides, solvents or ag-
gressive detergents to clean the appli-
ance; these may damage the plastic or
coated surfaces.
15. If you detect a smell of burning or smoke
coming from the appliance, shut it o, turn
o the main gas valve, open all windows
and call for assistance. Risk of injury due to
burning, smoke inhalation or intoxication.
16. To keep the appliance in good working
order, it must be serviced annually and
have its combustion tested as required
by local legislation. The technician doing
these jobs must be qualified and fill out

INSTRUCTIONS FOR THE USER
It is essential to drain the heater if it will
not be used and is in an area subject to
freezing temperatures.
To drain the heater, you must:
a) turn o the burner and close the gas
supply valve;
b) close the upstream water supply valve;
c) remove the cold water supply pipe
and remove the safety valve;
d) connect a hose, of adequate length to
reach the drain, to the water inlet fittin
(blue ring) on the heater;
e) open the hot water supply valve down-
stream of the water heater.
Warning!
When draining the heater, the water
leaving the heater can be very hot.
Clean using a cloth dampened with soapy
water. Do not use aggressive detergents,
insecticides or toxic products.
If the appliance is used in full compliance
with current legislation, it will operate in a
safe, environmentally-friendly and cost-e
cient manner.

RECOMMENDATIONS
FOR PREVENTION OF LEGIONELLA
GROWTH
Legionella are small rod shaped bacteria
which are a natural constituent of all fresh
waters. Legionaries’ disease is a serious
pneumonia infection caused by inhaling
the bacteria Legionella pneumophilia or
other Legionella species.
This bacterium is frequently found in do-
mestic, hotel and other water systems and
in water used for air conditioning or air cool-
ing system. Hence the main intervention
against the condition is prevention, through
control of the organism in water systems.
The European standard CEN/TR 16355
gives recommendations for good practice
concerning the prevention of Legionel-
la growth in drinking water installations
but existing national regulations remain in
force.
This storage water heater is sold with a
thermostat set at a temperature higher than
60°C; it means it is enabled to carry out a
“thermal disinfection cycle” to restrict the
Legionella growth inside the tank.
To prevent it from stagnating for long peri-
ods, water must be used or run abundantly
at least once a week;
WARNING!
Water heated to more than 50°C can
cause serious burns. Always check the
temperature of the water before using it.

WARNING!
Install the appliance to a solid wall, not
subject to vibrations.
When drilling the wall, take care not to
damage any existing electrical wiring or
pipes.
Make sure the installation site and any
systems to which the appliance must be
connected comply with applicable reg-
ulations.
POSITIONING
To allow easy access for maintenance,
make sure to install the unit with sucient
clearance around it.
Position the appliance near the chosen
wall so that the two inlet and outlet pipes
are parallel to it.
Should the water heater be installed in
the corner between two walls, keep suf-
ficient distance between the wall and the
appliance for the installation and disman-
tling of the components.
Place of installation
The choice of installation location must
observe applicable regulations.
The appliance must be installed perfect-
ly vertical. The appliance may not be in-
stalled in the vicinity of a source of heat.
Do not install the appliance in a place
where the temperature may fall below
0°C.
WATER CONNECTION
• Connect the heater to the water distri-
bution system using a 3/4” pipe. The
cold water inlet is on the right (blue
ring) while the hot water outlet is at the
left (red ring) as seen from in front of
the heater.
• The heater must be fi tted with a water
safety valve - non-return valve (sup-
plied with the heater) fi tted to the inlet
pipe (blue ring). You must not tamper
with the valve for any reason.
• Make sure by running the water for
some time, that there is no foreign ma-
terial in the water supply line, such as
swarf, sand, pipe dope etc.
Should any such material enter the
water safety valve - non return valve,
there can be faulty valve operation
and in some case faults to the valve
itself.
• Make sure that the water supply pres-
sure is lower than 8 bar (0.8 MPa). If
the pressure is higher, you must fi t a
high quality pressure reducer valve.
In this case the safety valve will nec-
essarily drip during heating. Said drip-
page must appear even if upstream of
the valve there is a non-return valve.
• Avoid the dripping of the valve falls on
to the water heater.
Apply the valve, envisioning a small
collection funnel (drip) connected to
the drain.
IMPORTANT!
If the appliance is installed in a hard wa-
ter area (> 200 mg/l), a softener should
be installed to limit the amount of limes-
cale building up in the heat exchanger.
The guarantee does not cover damage
caused by limescale.

CONNECTION TO THE CHIMNEY
B 11bs-type appliances are open-cham-
ber versions designed to be connection
to a flue gas discharge duct which re-
leases fumes towards the outside; com-
bustion air is taken directly from inside
the room in which the water heater is in-
stalled. Flue gas is discharged through a
natural draught system.
This type of appliance cannot be in-
stalled in a room that does not meet the
ventilation requirements of applicable
regulations.
So that the normal operation of the ap-
pliance is not compromised, the place in
which it is installed must be suitable with
regard to the operating limit temperature
value and the appliance should be pro-
tected so that it does not come into di-
rect contact with atmospheric agents.
The appliance is designed for wall in-
stallation and must be fitted onto a wall
capable of withstanding its weight. When
creating a technical compartment for
housing the appliance, leave sucient
clearance around the module to ensure
easy access to its interior.
- The combusted gas fumes must be
discharged outdoors via a pipe of min-
imum diameter 80 mm fitted into the
hood of the appliance as indicated
in the instructions and alternatives of
applicable regulations (principally UNI-
CIG 7129 and 7131).
- The flue must have a good draw.
- Avoid horizontal, downwards or con-
stricted sections of flue pipe, since
these can compromise the combus-
tion eciency of the appliance.
- If the flue pipe is run through a cold,
unheated area, it should be fitted with
an insulating jacket to prevent con-
densation forming.
- Never remove, modify or replace the
appliance’s hood, since it is an integral
part of the gas water heater’s combus-
tion system.
- The installation technician is alone re-
sponsible for installing the flue pipe
properly.
For correct gas-fi red water heater op-
eration, the fl ue gas hood must be po-
sitioned as shown in the fi gure. Avoid
absolutely any other type of installation
such as those illustrated below.

12
GB
FLUE GAS PROTECTOR
OPERATION AND CONNECTION
Water heaters are equipped with a de-
vice which shuts of gas to the burner and
hence stops the unit working when the
flue is partly or completely obstructed.
This device is composed of a thermostat
(A) set to 87±3°C mounted to the edge of
the hood (B) and connected to the fitting
interrupted by the gas valve.
This is part of the hood kit provided with
the appliance, and must be installed as
described below.
• Install the fl ue gas hood “A” turning it
to the best position with reference to
the sensor “B” and the cable exit from
the water heater.
• Connect the cable terminals “C” to
the contacts of the fl ue gas protector
(Fig.2).
• Proceed with normal water heater
start-up.
Should the appliance block, it must be
re-started as follows:
• as followswait 10 minutes after the
block occurs;
• ully press the re-arm button “D” on the
thermostat (Fig.3);
• re-start the water heater by following
the instructions for the normal ignition.
Should the defect repeat, do not repeat
appliance ignition but request the inter-
vention of a qualified technician to re-
move the cause of the problem.
Make sure that the combustion products
are properly expelled by measuring the
CO2content at the nominal heat output.
This value should not exceed that indi-
cated in the Technical Data table.
If the value is greater, check the ecien-
cy of the flue gas exhaust system. If it is
not possible to bring the CO2value with-
in the limit indicated in the Technical Data
table, do not start the appliance.
WARNING!!
THE FUMES SENSOR MUST NOT BE MOD-
IFIED OR DISABLED; DOING SO CAN COM-
PROMISE THE OPERATION OF THE APPLI-
ANCE.
POOR DRAW CAN CAUSE THE COMBUST-
ED GAS TO FLOW BACK INTO THE ROOM

WARNING!
Installation, first ignition and mainte-
nance work must be performed by qual-
ified personnel only, in accordance with
the instructions provided.
- Make sure that the main gas supply
matches the gas type on the unit’s
data plate
- Open all doors and windows
- Make sure there are no sparks or na-
ked flames in the room
- Water heaters are normally adjusted
for operation using methane gas G20
(PCI) 8100 kcal/m3 approximately. No
adjustment is needed if this gas is in
use.
Adjustment for other types of gas must
be done only by qualifi ed personnel.
- Use a 1/2” size pipe to connect the gas
supply to the valve.
- We suggest you fi t a stop valve in the
gas supply line, upstream of the gas
unit.
- Make the connection to the gas sup-
ply using rigid pipes (steel, copper
etc) and not thermoplastic nor rubber
pipes.
- After taking o the cover and making
the connection, check for leaks in the
gas system using soapy water.
Do not use a fl ame for this test.
The water heater has a magnesium an-
ode fitted in the tank. The life of the an-
ode
is proportional to the average tempera-
ture, the chemical composition and the
amount of water supplied.
We suggest you check the state of the
anode every 18-24 months, noting that
the surface must be relatively smooth.
If the diameter is less than 10-12mm, we
suggest you replace the anode with a
new original anode.
The anode is fi tted in the lower part of
the water heater, below the protection
cover.

SAFETY DEVICES
To guarantee the correct functionality of
the appliance, this is equipped with the
following safety devices:
- Thermocouple flame control
it interrupts the flow of gas in case of
no pilot flame. The repetitive, not oc-
casional, intervention of this safety de-
vice, indicates an incorrect functioning
of the appliance for which the inter-
vention of qualified sta is necessary.
- Overtemperature thermostat
acts with the same methods of the
thermocouple in case the water tem-
perature exceeds 90°C; in this case,
the appliance cannot be re-ignited un-
til the hot water has been drained.
However, the intervention of qualified
sta is necessary for the removal of
the defect before re-ignition of the ap-
pliance.
