6 COMMISSIONING, OPERA TION AND SHUTDOWN
6.1 Tests to be performed prior to first star t
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.
