BOILER OPERATION
The Boiler Control Thermostat responds to the temperature of the water within the boiler and switches power
to the burner when heat is required.
The burner has an independent control system which regulates the firing and (shut-off) of the burner.
Automatic firing of the burner will occur when the water temperature within the boiler falls below the
control thermostat set point which will continue to run until the water temperature rises to the temperature set
on the boiler control thermostat.
SWITCHING THE BOILER ON
-
Check there is water in the system.
-
Check radiator valves are on.
-
Turn on oil supply.
-
Switch electrical supply to the boiler on (including time clock) and then set the boiler control thermostat
to recommend setting.
BOILER CONTROLS
BOILER CONTROL THERMOSTAT
The temperature of the water within the boiler is controlled and maintained by the Boiler Control
Thermostat located on the boiler control panel.
TEMPERATURE SETTINGS:
The Boiler Control Thermostat has a range of 50°C to 80°C. The recommended setting for the boiler control
thermostat is:
WINTER Heating and hot water supply 80°C
SUMMER Domestic hot water supply 65°C
It is not recommended to operate the boiler with a thermostat setting of less than 60°C as this will precipitate
corrosion, thus reducing the life of the boiler.
HIGH LIMIT STAT
The high limit lockout will occur when the water within the boiler is or has overheated e.g. reached a
temperature above that set on the high limit thermostat.
TO RESET THE BOILER
When the boiler has had time to cool, unscrew black cap and press button on the control panel to reset.
LOCKOUT INDICATOR: RED
The lock out indicator will illuminate when the burner has failed to fire, e.g. No fuel or an electrical fault.
Wait for two minutes then press the manual reset button (coloured red – Fig 1) on the control box to reset.
