HUTDOWN DUE TO INSUFFICIENT

WATER CIRCULATION

If the red L.E.D. "L" is

and

off,

possible cause for this

state is an insufficient

pressure of water in the system.

Check the system pressure on the

pressure gauge "M" and if it is less

than 0.5 bar, consult your installer for

checking and refilling the system.

Then turn off and turn back on the

boiler by means of the selector knob

"A". If the boiler does not start up

again and the L.E.D. "L" remains

illuminated, contact an Authorised

Service Centre.

If there are frequent drops in pressure

within the system, have a plumber

check the heating system for possible

water leaks.

EMPORARY SHUTDOWN DUE TO

DEFECTIVE DISCHARGE OF

EXHAUST FUMES

The boiler is fitted with safety devices,

which in the event of a defective

discharge

automatically interrupts the gas supply,

thereby shutting off the boiler.

The shut-off of the boiler is temporary

and is indicated by the illumination of

the yellow L.E.D. "E" for a period of

about 15 minutes.

Once this time period has passed and

the discharge state of exhaust fumes

has returned to normal, the boiler

automatically turns back on.
