6. CONTROL DEVICE FOR THE EVACUATION OF GASES (T.T.B.)
6.1. The T.T.B. safety element that is fitted to the water heaters ensures that combustion products are
evacuated properly and should, therefore, not be deactivated and uncontrolled interventions should
not be performed on it. In case of disturbances in the evacuation of combustion products the device
interrupts the gas supply to the burner.
6.2. If the T.T.B. device is activated once the water heater is turned on, revise the burnt gas outlet by checking the
evacuation with a cooled mirror with running water, or any other measuring device approved for this purpose.
6.3. In case of damage, use only original spare parts as the T.T.B. device may not work properly
otherwise.
6.4. The T.T.B. device should be replaced by experts as follows:
- Remove the defective T.T.B. device by loosening the two screws holding it together.
- Remove the thermocouple.
- Insert a new original thermocouple.
- Attach the T.T.B. device to the smoke box without forcing the screws.
- Check it is working properly.
6.5. Models for “Exclusive outside installation” do not need this device.
VERY IMPORTANT
In the premises where the water heater is located, do not forget to open the air inlet
and, where appropriate, the air outlet as per the requirements of the GAS Installations Regulations.
To maintain a clean Environment, remember to dispose of used batteries in containers
prepared for collecting these products.
