In winter
conditions,
i.e. central heating and domestic hot water,
the thermostat
should be set at position 5 or 6.
For summer
conditions,
i.e. domestic hot water only, the
thermostat
should be set at position 3.
These settings, however, 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.
Control of water temperature
1. Adjust the boiler thermostat
(8) to give the required
temperature
of central heating.
2. The boiler thermostat
automatically
switches the main burner
OFF and ON to maintain the selected temperature.

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.
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.
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.
