1.2.4 Combustion products discharge safety
device
The heater has been fitted with a combustion products
discharge safety device. It is the function of the safety
device to prevent flue gases from the water heater
entering the room where the water heater has been
placed, instead of passing through the flue to outside
atmosphere. The gas supply is disconnected as soon as
hot gases flowing over the sensor activate the device.
After the cause of the re-entry of flue gases has been
traced the device can be put back into operation by
pressing its reset button. If this failure occurs frequently,
this indicates that the flue suffers from down draught
conditions. It is recommended that a competent person
carry out the necessary remedial action.
Important
The combustion products discharge safety device must
never be put out of operation. Re-entry of flue gases to
the building could be harmful and cause poisoning or
death.
1.3 Technical information
