Gas Evacuation Control Device (T.t.b.) - Cointra CMB-5 Instrucciones De Instalacion, Uso Y Conservacion Para El Instalador

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.
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.
