It is the aim of the T.R.S. to prevent flue gasses from the water heater entering the room where the water heater has been placed, instead of passing through the flue to outside atmosphere. The thermo-couple circuit is interrupted and the gas supply is disconnected as soon as the T.R.S. is activated by heating of the sensor by the hot gasses.

After the cause of the reentry of flue gasses has been traced the device can be put back into operation again. In case of T.R.S. the RESET button has to be pressed first.

If this failure occurs frequently, this indicates that the flue suffers from down draught conditions. We advice that necessary remedial actions be carried out by a competent person.

Important

If the water heater is put out of operation by a failure, this may be caused by the T.R.S.. If there is a RESET button on the thermostat this is visible because the button rose. The device can be put back into operation by pressing the RESET-button.

The T.R.S. should never be put out of operation. Reentry of flue gasses to the building could be harmful and cause poisoning or death.
