GENERAL INFORMATION To ensure you get the very best from your new Worcester Heatslave oil boiler, please read these notes and instructions care- fully. The Worcester Heatslave is a combination boiler which pro- vides mains-fed domestic hot water and full central heating. It utilises a Heatslave tank and a heat exchanger, which ensure that whenever a tap is turned on there is an instantaneous output of hot water.
ROOM-SEALED BALANCED FLUE BOILERS Air for this type of boiler is supplied via the balanced flue ter- minal, and no other air supply is required, except for ventilation if the boiler is installed in a cupboard or compartment. ELECTRICAL SUPPLY The mains supply for your Heatslave boiler is 230/240 volts AC-50Hz.
SHOWERS, BIDETS, TAPS AND MIXERS Any taps and mixers used with your system must be suitable for operating at mains pressure. For a shower it is recommended that you fit a thermostatical- ly-controlled shower valve, as this will give added safety by pro- tecting against excessive water temperatures.
If ‘HEATING’ and ‘HOT WATER’ are selected together The central heating will operate in response to any system controls, and hot water will be supplied when a tap or shower is turned on. The Heatslave tank will be kept at the pre-set tempera- ture, as in the HOT WATER mode.
EXTERNAL PROGRAMMER You may opt to have a programmer sited away from the boil- er, in which case your installer will provide setting and operating instructions. CENTRAL HEATING TEMPERATURE CONTROL The central heating temperature control knob on the boiler facia panel enables you to control the temperature of the water in your radiators.
INDICATION LIGHTS There are two indicator lights on the facia panel — POWER ON and LOCKOUT. The POWER ON light shows that there is an electrical power supply to the electrical control panel. This will remain on at all times provided there is an external electrical supply and the internal fuse has not blown.
TO START YOUR BOILER First ensure that the oil supply is turned on. Now switch on the mains electricity and turn the hot water and central heating temperature control knobs to maximum. Set the user operating switch (or programmer) so that both HEATING &...

If the pressure falls below this minimum level, the system must be re-pressurised using the method described by your installer. To ensure that the boiler and system are full of water and pressurised, check the pressure gauge indicator needle. Consult your installer or service engineer if the system continues to lose pressure, as this could indicate a leak.
HARD-WATER AREAS If you live in an area where the mains water is exceptionally hard, it is recommended that an in-line scale inhibitor is used in your boiler and system, in strict accordance with the requirements of your local water company and bye laws. An isolating valve, to facilitate servicing, should also be incorporated.
The appliance has been installed for more than 1 year but less than 2 years and has not had a first annual service by an approved company. Our Field Service Engineer finds no fault with the appliance (see note). The cause of breakdown is misuse or with other parts of your plumbing/heating system, or with equipment not supplied by Worcester.
