CLOUDS OF WHITE 'SMOKE' FROM FLUE
TERMINAL
When the burner is operating, it is not unusual to see
water vapour clouds steaming from the flue terminal,
particularly on cold 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.
A small volume of water may discharge from the bottom
of the water heater when a hot tap is suddenly closed.
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 Water Supply on page 17).
HIGH GAS BILLS
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.
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 controller/s (if installed) and
on the front of the water heater on the OK MONITOR.
If an error code appears:
1. Close the hot tap, turn off the controllers and switch
off the power to the water heater.
2. Wait 5 minutes, then switch on the power to the water
heater, turn on a controller and open a hot tap.
If the error code persists, turn off the hot tap and turn off
the controller. Take note of the code and phone
Southcorp Water Heaters Australia or their Accredited
Service Agent for service.
