3.11 Product data on energy consumption
The following product data complies with the requirements of EU Regulations 811/2013, 812/2013, 813/2013 and 814/2013
as supplement to the Directive 2010/30/EU.
3.12 Operational instructions
Hot water
Open the gas and water valves and ensure that all joints are
tight.
Place the on-off switch (Fig. 8, [1]) in the operating position
(Chapter
5.3), so that the appliance is ready for use.
When a hot water tap is opened, the water flow sensor will send
a signal to the control unit. This signal initiates the following:
•The fan starts.
• Spark generator provides a spark at the burner and then
the gas valve opens.
•The burner ignites.
• The ionisation electrode ensures the flame is present.
• The water temperature is controlled automatically by the
sensors/controllers according to the temperature
selected.
Safety cut-off when safety period is surpassed
The appliance attempts three starts before it safety circuit
locks out. A single start attempt lasts 5 seconds followed by a 5
second break before having a new attempt. The start up cycle
will last a maximum of 35 seconds before the appliance locks
out on flame failure.
In this case, if the attempts to ignite go on too long, the security
mechanisms prevent operation.
Safety cut-off due to excessive water heating
The control unit detects the water temperature via a NTC
sensor located in the hot water flow pipe and the temperature
sensor located in the heat exchanger. If it detects an excessive
temperature it provokes a safety cut-off.
Restarting after safety cut-off
To restart the appliance following a safety cut-off:
▶ Press the reset key (Fig. 8, [2]).
