Temporary Shutdown Due To Defective

Discharge of Exhaust Fumes

The boiler is fitted with safety devices, which in the event of a

defective discharge of exhaust products, automatically interrupts

the gas supply, thereby shutting off the boiler.

The shut-off of the boiler is temporary and is indicated by the illumi-

nation of the yellow L.E.D. "H" for a period of about 15 minutes.

Once this time period has passed and the discharge state of

exhaust system has returned to normal, the boiler automatically

turns back on.

If this situation occurs frequently, contact a local Service Agent so

that they may check that the exhaust fumes are being expelled

correctly, that the flue is installed correctly and that the area is

ventilated properly.
