2.10 Operation description

Hot water

This heater is equipped with electronic automatic ignition, thus

its operation becomes simple.

For such it is enough to:

▶ Open the gas and water shut-off valves and check the

tightness of all the connections.

▶ Place the On/Off button (Fig. 4, [3]) in the operating

position.

After this procedure, when opening a hot water point, the

ignition will occur automatically.

Spark shut-down when the ignition time is exceeded

If it is not possible to obtain the flame within the safety interval

stipulated, a gas shut-off is carried out in the valve.

The presence of air in the gas supply tube (initial start-up of the

appliance or start-up after long periods of inactivity) may cause

a delay in the ignition.

In this case and if the ignition attempt is too long, the safety

devices block the operation of the appliance by interrupting the

gas flow.

Safety shut-down due to an excessively heated water

temperature

The ignition unit detects the temperature of the water through

the temperature limiter placed in the combustion chamber. In

the event that it detects excessive temperature, it causes a

safety shut-down.

Re-start after safety shut-down

To put the appliance back into operation after having caused a

safety shut-down:

▶ Close and re-open a hot water point.
