To light the boiler. Refer to Frame 2
If a programmer is fitted refer to separate instructions for the
programmer before continuing.
1. Check that the electricity supply to the boiler is OFF.
2. Open the control panel drop-down door and ensure that the
thermostat knob (G) is in the OFF position.
3. Switch ON the electricity supply to the boiler and check that
all external controls, e.g. room thermostat etc., are ON.
4. Set the boiler thermostat knob (G) to position 6. The fan will
start. After the fan has run for a few seconds the pilot
solenoid valve should open and the intermittent spark
commence, continuing until the pilot is established. The
main burner will then cross-light smoothly.
Winter conditions (i.e. central heating and domestic hot water).
The thermostat should be positioned at setting 5 or 6.
Summer conditions (i.e. domestic hot water only). The
thermostat should be positioned at setting 2.
These settings are offered for general guidance only and other
settings may be found preferable, dependent upon the type of
system installed or as recommended by the installer.
To shut down the boiler
1. For short periods
Turn the boiler thermostat knob (G) to OFF. When heating is
again required, restore the knob to its original setting.
2. For longer periods
a. Turn the boiler thermostat knob (G) to OFF.
b. Switch the electricity supply to OFF.
Frost protection
If no frost protection is provided and frost is likely during a short
absence from home, leave the heating controls (if fitted) at a
reduced temperature setting.
For longer periods, the entire system should be drained -
including the domestic water supply.
If the system includes a frost thermostat then, during cold
weather, the boiler should be turned OFF at the time switch (if
fitted) ONLY. The mains supply should be left switched ON,
with the boiler thermostat left in the normal running position.
Control of water temperature
1. Set the boiler thermostat knob (G) to give the required
temperature for central heating.
2. The boiler thermostat automatically switches the main
burner OFF and ON to maintain the selected temperature.
To relight the boiler
Repeat the procedure 1 - 4 detailed in 'To light the boiler'.
Boiler Overheat Thermostat
(Fitted for sealed systems only)
For a boiler fitted with a safety 'cutout' thermostat: this
thermostat will shut down the boiler in the event of overheating.
Should this occur, allow the boiler to cool, press the reset
button (J) on the overheat thermostat then relight as detailed in
steps 1-4 under 'To light the boiler'.
If the 'cutout' condition persists turn off the boiler and consult a
CORGI registered installer.
Loss of system water pressure
(Boilers fitted with the Overheat Thermostat Kit only)
If the red arrow on the system pressure gauge is set above zero
and the system pressure is seen to fall below this value over a
period of time then a water leak is indicated. In this event a
CORGI registered installer should be consulted.
DO NOT FIRE THE BOILER IF THE PRESSURE HAS
REDUCED TO ZERO FROM THE ORIGINAL SETTING
