9. COMBUSTION PRODUCTS DISCHARGE

SAFETY DEVICE

This sensor measures the temperature of the flue and is

located in the diverter on the flue outlet. This important

safety device prevents products of combustion entering a

room and must operate at all times when the cooker is in

use.

The flue sensor switches the burner off if the temperature is

too high and the cooker refuses to relight. You must wait 30

minutes before you can press the reset button in the control

panel to relight the cooker. When there is repeated

shutdown of the cooker the flue/chimney must be

investigated immediately:

9.1 The Reset button is behind the control panel door:

 •Presstoreset.

9.2 After each shutdown by the flue sensor, an operation test of

the cooker and flue must be carried out. (See

Commissioning).

NOTE: BEFORE PROCEEDING, ISOLATE THE ELECTRIC

SUPPLY
