Exhaust connection
The device belongs to B11BS, therefore the exhaust gases must be evacuated outside with the interposition of a
draftdamper and smokes sensor. The first thing to do is to mount the draftdamper; screw the screws in the suitable
holes on the upper cover of the water heater.
Afterwards, connect the fastons which are fixed on cables' limbs on the tongues of the sensor placed on draftdamper's
backside. The cross connection to the fire-tube must have a diameter according to the technical data schemes.
The laws in force on the matter must be followed.

The smokes sensor is a thermostat with a fixed setting. If the draftdamper overheats the smokes sensor opens the
contacts by interrupting the themocouple's circuit and in this way it closes the gas flux to the valve.
The smokes sensor is an obligatory security which stops the water heater in case of bad draft. The burner turn off to
avoids that the exhaust gases propagate outside and provoke even deadly damages on person.
