TO SHUT DOWN THE BOILER
1. For short periods
Turn the boiler on/off switch (C) to OFF.
When heating is again required, restore the switch to ON.
2. For longer periods
Turn the boiler ON/OFF switch (C) to OFF.
Switch the electricity supply to OFF.
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 or in IE a competent person.
CONDENSATE DRAIN
The condensate drain (F) must not be modified or blocked.
Blockage of the condensate drain, caused by debris or freezing,
can cause automatic shutdown of the boiler.
If freezing is suspected and the pipe run is accessible an
attempt may be made to free the obstruction by pouring hot
water over the exposed pipe and clearing any blockage from the
end of the pipe. If this fails to remedy the problem the
assistance of a CORGI registered installer or in Ireland a
competent person should be sought.
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 or in IE a competent person.
