This boiler is exclusively manufactured for British Gas by Ideal Boilers Ltd.
Control of water temperature
1.
Adjust the boiler thermostat (B) 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 shut down the boiler
1. For short periods
Set the boiler On/Off knob (B) to OFF.
When heating is again required, turn the knob to the desired
position.
2. For longer periods
Set the boiler On/Off knob (B) to OFF.
Switch OFF the electricity supply.
To relight the boiler
Repeat the procedure 1 - 8, detailed in 'To light the boiler'.
Frost protection
If no frost protection is provided and frost is likely during a short
absence from home, leave the heating controls 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(es) ONLY. The mains supply
should be left switched ON, with the boiler thermostat left in the
normal running position.
Boiler Overheat Thermostat
The boiler is fitted with a safety 'cutout' thermostat. This will
shut down the boiler in the event of overheating. Should this
occur allow the boiler to cool, press the reset button (E) then
relight as detailed in steps 1-8 in 'To light the boiler'.
If the cutout condition still persists turn off the boiler and consult
a CORGI registered installer.
Loss of system water pressure
Boilers fitted with Sealed System Units only
If the red arrow on the unit 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 OPERATE THE BOILER IF THE PRESSURE HAS
REDUCED TO ZERO FROM THE ORIGINAL SETTING.
Escape of gas
Should a gas leak be suspected, contact your local gas supplier
without delay.
Do NOT search for gas leaks with a naked flame.
Cleaning
For normal cleaning simply dust with a dry cloth.
To remove stubborn marks and stains, wipe with a damp cloth
and finish off with a dry cloth.
Do NOT use abrasive cleaning materials.
Maintenance
The appliance should be serviced at least once a year by a
CORGI registered installer
.
