CLOUDS OF WHITE 'VAPOUR' FROM THE FLUE TERMINAL
During the heating cycle, it is not unusual to see water vapour clouds
steaming from the flue terminal, particularly on cold or humid days. This
is normal operation of the water heater.
PRESSURE RELIEF VALVE DISCHARGING
A pressure relief valve is incorporated into the water heater controls.
This valve protects the water heater, by allowing water to escape, in the
event of excessive pressure build-up in the waterways.
 Normal operation
A small volume of water may discharge from the bottom of the water
heater when a hot tap is suddenly closed.
 Continuous dribble
A continuous dribble may indicate the water supply pressure is
above the design pressure for the water heater. If so, a pressure
limiting valve must be installed on the cold water supply pipe to the
water heater (refer to
ERROR CODE
The water heater provides a diagnostic error code in the event of an
interruption to its operation. The error code is displayed on the indication
window on the front of the water heater as a flashing red LED whilst the
hot tap is open. If the red LED is flashing:

Close the hot tap.

Check the gas isolation valve at the gas inlet to the water heater is
fully open.

Wait 5 minutes, then open a hot tap.
If the error code persists, count the number of flashes and then turn off
the hot tap. Phone Rheem Service or their nearest Accredited Service
Agent to arrange for inspection.
HIGHER THAN EXPECTED GAS BILLS
Should you at any time, feel your gas bill is higher than expected, we
suggest you check the following points:

Is one outlet (especially the shower) using more hot water than you
think?
Carefully review the family's hot water usage. Inexpensive flow
control valves can be easily fitted to the shower outlets to reduce
water usage.

Has there been an increase in hot water usage?
An increase in hot water usage will result in an increase in water
heater operation.

Has your water heating tariff rate been increased by your gas
retailer since your previous bill?
IF YOU HAVE CHECKED ALL THE FOREGOING AND STILL BELIEVE YOU NEED ASSISTANCE, PHONE
RHEEM SERVICE OR THEIR NEAREST ACCREDITED SERVICE AGENT.
