3. USEFUL INFORMATION

AND TROUBLESHOOTING

OILER SHUTDOWN SITUATIONS

The boiler is equipped with safety

devices that intervene in certain

situations and shut it off. Most of these

situations are communicated by means

of the L.E.D.s and at times the user

may be able to remedy them.

HUTDOWN DUE TO IGNITION

FAILURE

In the event that

the

automatic

ignition of the

burner

has

failed, the red

L.E.D. "F" will

illuminate. In order to reset the ignition,

the button "H" must be pressed and

released. Should the boiler fail to ignite

a second time, check that the external

gas cock is open. If the problem

persists, contact an Authorised Service

Centre.

HUTDOWN DUE TO OVERHEATING

In the event that the safety limit is

exceeded for the temperature of the

water in the boiler's primary exchanger,

the thermostat shuts off the boiler and

the red L.E.D. "J" illuminates.

To remedy this situation, wait a few

minutes to allow the exchanger to cool

down, then press and release the reset

button "H".

If this situation occurs frequently,

contact an Authorised Service Centre.
