Central Heating
When a demand is made for heating by the system controls
MAINTAINING YOUR
APPLIANCE
(i.e. a programmer or room thermostat). A pump will energise
circulating primary water around the heating system and the burner,
after a few seconds, will light. The heat output from the appliance in
this mode has been factory set to give maximum output or as reset by
your installer. The appliance will operate as necessary to maintain the
temperature of the radiators at the level set by the adjustment of the
boiler Temperature Control Knob. (See Fig. 1.)
If the system no longer requires output to maintain the desired
room temperature, the burner will extinguish. The pump and fan will
continue to run for a short period to dissipate the residual heat from
the appliance and then switch off.
The appliance will supply heat to the central heating system as
required.
Your new Worcester boiler represents a long-term
investment in a reliable, high quality product.
In order to realise its maximum working life, and to ensure
it continues to operate at peak efficiency and performance, it is
essential that your boiler receives regular, competent servicing
and annual maintenance checks beyond the initial 12 month
guarantee period.
Hot Water
The appliance operates to supply only domestic hot water when
the heating temperature mode is fully anti-clockwise, at the 0 position
or the timer is programmed to OFF mode.
Regular service contracts can be arranged with your installer
– however if you have difficulty making a satisfactory
arrangement simply contact Worcester on 08457 256206 for
help.
If you would like to know more about Worcester’s extended
warranty options please tick the appropriate box on your
warranty registration card.

FROST PRECAUTIONS
If the appliance is not to be used for a long period of time and
there is a likelihood of freezing, then the appliance should be drained.
The Worcester Technical Helpline will advise you on suitable frost
precautions. The boiler has an in-built frost thermostat which will
protect the appliance should the temperature of the boiler drop below
approximately 10°C.

SERVICE
Boiler demand :
System is calling for heat
Annual servicing is important in order to ensure continuing
high efficiency and long life for your appliance. In the event of any
difficulty in making suitable servicing arrangements, Worcester
personnel or other competent persons will discuss regular servicing
arrangements and offer a comprehensive maintenance contract.
Burner ON
Lock-out
:
:
Burner is firing
There is a fault condition
Steady light - Overheat
Flashing light - Flame failure
WARNING
If a gas leak exists, or is suspected, turn off the gas supply to the
appliance at the service cock on the meter and consult your local
service engineer.
Do not touch any electrical switches to turn them either on or off.
Open all windows and doors. Do not smoke. Extinguish all naked lights.
TO LIGHT THE APPLIANCE
Check that the water valves to the central heating circuit are open.
Check that the needle on the pressure gauge is not below the
required pressure - sealed system only.
Switch on the mains electricity. Set the room thermostat, if
fitted, to maximum. Turn the boiler temperature control fully
clockwise to the maximum position. The burner will light. Set the
boiler temperature control and the room thermostat/cylinder
thermostat, if fitted, to the desired temperature.
CLEANING
Do not use abrasive cleaners on the outer casing. Use a damp
cloth and a little detergent.
TO STOP THE APPLIANCE
For Short Periods
Turn the boiler temperature control fully anti-clockwise to the
‘O’ position.
For Long Periods
Turn the boiler temperature control switch to the ‘O’ position.
Switch off the mains electricity.
Any programmer will require resetting if mains supply has been
disconnected.
ELECTRICITY SUPPLY
FAILURE
If the electricity supply fails the appliance will not operate.
Once the supply is restored the appliance will return to normal
operation.
Check that the settings of any programmer or time control
have been maintained.
