1.2.2 Combustion products
discharge safety device
The water heater has been fitted with a
combustion products discharge safety
device. It is the function of the safety
device 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 gas supply is
disconnected as soon as the device is
activated by hot gasses flowing over
the sensor.
After the cause of the re-entry of flue
gasses has been traced the device can
be put back into operation by pressing its
reset button.
If this faillure occurs frequently, this
indicates that the flue suffers from down
draught conditions. It is recommended
that a competent person carry out the
necessary remendial action.

The combustion products discharge
safety device should never be put out
of operation. Re-entry of flue gasses
to the building could be harmful and
cause poisoning or death.
