1.02 Introduction
The Gas Multi Point water heater is a “room-sealed” appliance: it takes in the air required for com-
bustion and encloses all the combustion products in an hermetic compartment. The discharge of
fumes and intake of combustion air are managed through air/flue pipes that may be run horizontally
in all directions, or through a concentric flue running vertically or horizontally.
The main components of the water heater are:
-Acompact heat exchanger in copper, formed by four pipes with external finning and internal
turbulence activators.
-An insulated combustion chamber to reduce heat loss and thus improve efficiency.
-Four stainless steel burners, an oxidation and thermal shock-resistant material specially developed
for this product.
-Afan to discharge combustion products and draw in combustion air.

-Ahigh limit thermostat
-Asteel room-sealed compartment treated against corrosion, enclosing components.
-An air differential pressure switch which, to ensure safe operation, allows burner ignition only
when the fan functions normally.
-Anewly-designed gas ignition valve assembly, comprising a fullly modulating gas valve and a
flame control device. (Ignition is by an intermittent pilot flame; at the moment a hot water tap is
opened, a pilot flame is sparked electronically which lights the main burners.)
-Aflowmeter.
-Amodulating device which controls the gas valve during use in response to the signal from the
flowmeter, the preset temperature and the desired flow rate (water temperature is kept constant
with no waste due to temperature fluctuation).
-Awater temperature control which allows the user to set the desired temperature - between 40°C
and 55°C.
-Five LEDs: one green signalling that the water heater is on, and four yellow displaying water tem-
perature.
-Atemperature sensor.
-Aexpansion vessel 3 bar.

The water heater allows the flue outlet to be taken from the rear of the water heater or from either side.
A standard flue length of 0.75 metres is provided. Alternative lengths of two or three metres can be
supplied.
It is absolutely essential, to ensure that products of combustion discharging from the terminal cannot
re-enter the building, or enter any adjacent building, through ventilators, windows, doors, natural air
infiltration, or forced ventilation/air conditioning.
3.6 Gas Supply
If necessary the local Gas Region should be consulted, at the installation planning stage, in order to
establish the availability of an adequate supply of gas.
An existing service pipe must not be used without prior consultation with the Local Gas Region.
A gas meter can only be connected by the Local Gas Region, or by a Local Gas Region's Contractor.
Installation pipes should be fitted in accordance with BS6891-1988.
Appliance inlet working pressure must be 20 mbar MINIMUM.
Pipework from the meter to the boiler must be of an adequate size (3/4" or 22 mm).
Do not use pipes of a smaller size than the boiler inlet gas connection.
The complete installation must be tested for gas soundness and purged as described in BS6981-1988.
All pipework must be adequately supported. An isolating gas valve is provided and should be fitted.
3.7 Water supply
Facing the appliance the cold water inlet is on the right with the hot water outlet on the left.
The maximum domestic water pressure for the inlet supply is 10 bar (145 P.S.I.). If the cold mains supply
exceeds 5 bar (72 P.S.I.), a water governor or pressure reducing valve must be fitted in an accessible
position preferable between 3 and 5 metres before the appliance.
Such a valve must be approved by the water research council.
Attention - Is drawn to the Model Water Byelaws.

6 COMMISSIONING, OPERA TION AND SHUTDOWN
6.1 Tests to be performed prior to first start
Before starting the water heater for the first time you should check the following:
-That the gas and water taps upstream of the water heater, are open.
-That there are no gas or water leaks along the lines or in the appliance.
-That electric connections have been performed properly (paying the closest attention to matching line and
neutral wires) and that the appliance is corrected earthed..
-That there are no inflammable liquids or materials in the immediate vicinity of the appliance.
-That the gas pressure and gas flow are at the required levels.
-That the air inlet and flue gases exhaust pipes are properly connected (flue installation).
-That all hot water taps are turned off.
6.2 Commissioning
-Turn on the power.
-Set the switch on the instrument panel to “On” (the green LED should light up).
-Open a hot tap to draw water this will automatically activate the fan to start discharging combustion products.
The electronic device on the gas unit activates an electrode which ignites the pilot flame and simultaneously
verifies the completion of the ignition phase and allows the lighting of the main burner.
-In the event ignition of the pilot flame has failed, check the line and neutral connections for correct polarity.
6.3 Operation
Talent is a water heater designed for prompt production of hot water.
During drawing of domestic water, the flowmeter sends a signal to the electronic device which, in response to
the preset temperature and the desired flow, adjusts the gas valve. The water temperature is thus kept constant
and this eliminates the waste due to temperature fluctuation.
The user may select a temperature between 40°C and 55°C using the knob on the instrument panel.
The diagram in Fig. 10 shows the water heater temperature range, within which it may operate.

S.p.A.
6.4 Shutdown
To shut down the appliance turn the power supply off (switch *), and turn off the gas supply cock.
Note: You should shut down the appliance whenever you intend not to use it for a long period of time. During
long winter breaks, you should drain the water out of the water heater to avoid damage that might be caused by
freezing.
7. ADJUSTMENTS
The TALENT water heater is factory set and no adjustments are normally required, however the
following adjustments can be made if problems are found.
7.1 Adjusting the pressure and flow rate at the main burner
This appliance, being of the modulating-flame type, comes with two fixed pressure settings - for minimum and
maximum, as shown in the table - for each type of operating gas.
Remember: You should adjust the minimum pressure setting first to ensure a correct ignition of the burner, then
proceed to adjust the maximum pressure setting. Any adjustment of the minimum pressure modifies the maximum
setting. The following adjustments, given their extreme sensitivity, should be carried out solely by company expert
personnel.
7.2 Adjusting the minimum and maximum pressure settings
Start with an ignited burner:
-Connect an appropriate manometer to the burner pressure test point.
-Disconnect the power supply wires leading to the “Modureg” coil “c”.
-Disconnect the pressure balancing pipe “h”
- Remove the protection cap “d” fitted on top of the coil.

-Regulate the minimum pressure by turning nut “e”, anticlockwise to reduce it and clockwise to increase it.
-Turn the burner off three or four times by closing and opening the gas cock, checking every time that the
pressure level corresponds to the new setting and that the burner ignites normally. If that is not the case, an
additional adjustment is required.
-Upon completing this procedure, check the maximum pressure level.
-Wait until the pressure reading in the manometer has stabilized.
-Carefully press all the way down the pin “f” and keep it pressed. If you wish to adjust the maximum pressure
setting, turn slowly the regulating nut “g”, clockwise to increase it and counterclockwise to reduce it.
After adjusting the maximum and minimum pressure settings, reconnect the wires to the Modureg coil “c”, re-
attach the pressure balancing pipe “h” and replace the protection cap “d”. Now the water heater is set for
automatic operation. Remove manometer and check for gas soundness.
Note: If the “Modureg” coil fails to respond you must replace the complete “Modureg” unit. Any attempt to
replace only the coil might cause damage to the “Modureg” calibration.
Any adjustment made using the regulating screws should be carried out with caution.
