RECOGNITION OF ABNORMAL OPERATION
1. PRESSURE & TEMPERATURE RELIEF VALVE RUNNING:
It is not unusual for the valve to allow a small quantity of water to escape during the
heating cycle. The amount of discharge will depend on hot water usage. As a guide, if
it discharges more than 20 litres of water in 24 hours there may be a problem.
Continuous trickle:
Likely build up of foreign matter. Try gently raising the easing lever on the relief valve
for a few seconds. This may dislodge a small particle of foreign matter and rectify the
fault. Release lever gently.
Steady flow emitted:
Likely causes are excessive water supply pressure or a faulty pressure valve.
2. NO HOT WATER
Is the relief valve discharging too much water? See "Pressure & Temperature Relief
Valve Running".
Do you have the correct size water heater for your requirements? Sizing details are
available from your Dux supplier.
Is one outlet (especially the shower) using more hot water than you think?
Carefully review the family's hot water usage and if necessary check the shower flow
rates with a bucket and a watch.
If it is not possible to adjust water usage patterns, an inexpensive flow control valve can
easily be fitted to the shower outlet.
3. HIGH GAS BILLS
Is the relief valve discharging too much water? See "Pressure & Temperature Relief
Valve Running".
Is one outlet (especially the shower) using more hot water than you think? See "No Hot
Water".
Is there a leaking hot water pipe or dripping hot water tap? A small leak can waste a
large quantity of hot water.
Replace faulty tap washers and have your plumber rectify any leaking pipework.
