To shut down the boiler
Loss of system water pressure
1. For short periods
The pressure gauge located below the boiler on the right hand
side indicates the central heating system pressure. If the pressure
is seen to fall below the original installation pressure of 1 –2 bar
over a period of time then a water leak is indicated.
Set the mains ON/OFF switch (I) to OFF
2. For longer periods
Set the mains ON/OFF switch (I) to OFF, and switch the
electricity supply to OFF. For longer periods the entire system
should be drained.
To relight the boiler
Repeat the procedure detailed in 'To light the boiler'.
In this event a CORGI registered installer should be contacted.
If the cold system pressure is below 0.4bar the boiler will not
operate. The heating system will need to be re-pressurised to at
least 0.7bar. The boiler should then operate normally.
Escape of gas
Frost protection
The boiler is provided with a built-in frost protection system: It is
necessary the mains switch is kept in the ON position. For
longer periods, the entire system should be drained.
If the system includes a remote frost thermostat then, during
cold weather, the boiler should be turned OFF at the
programmer ONLY. The mains supply should be left switched
ON, with the boiler thermostat left in the normal running position.
Boiler overheat thermostat
This thermostat will shut down the boiler in the event of
overheating. The fault led (B) is will be illuminated. Press the
reset button (A) and the boiler will relight.
If the fault continues, turn off the boiler and consult a CORGI
registered installer.
Should a gas leak or fault 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.
Flame failure
The fault led (B) will be illuminated. Press the reset button (A)
and the boiler will relight.
If the fault continues, turn off the boiler and consult a CORGI
registered installer.
