Worcester HEATSLAVE 12/14 User Instructions & Customer Care Manual page 3

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.
The boilers control system gives priority to the domestic hot
water supply. This means that during hot water draw-off and
Heatslave tank recovery periods, the total output of the boiler is
directed to the Heatslave tank. If the central heating is switched on
during this period, the circulation of hot water to the radiators will
be temporarily interrupted but will resume as soon as the
Heatslave tank has been recharged to the temperature set on the
hot water control thermostat.
SERIAL NUMBER
Your boiler serial number and model number should always
be quoted in any contact with Worcester. This will help identify
spare parts and also avoid confusion and delays during any service
call-out. You will find these numbers on a label on top of the elec-
trical control box cover plate, and access can be gained by remov-
ing the top panel of the boiler casing.
FUEL
Your Worcester Heatslave pressure jet boiler is set to burn 28-
second kerosene fuel. Some models can be converted to burn 35-
second gas oil. If this conversion has been made your installer will
inform you.
PLEASE NOTE: Appliances fitted with a low-level discharge
flue MUST NOT be used with 35-second gas oil.
OPEN-FLUED BOILERS
Your installer will create airways (in walls or doors) to ensure
an adequate supply of fresh air to the boiler for combustion. Do
not block these airways, and never hang clothes or other com-
bustible materials over the boiler or against the flue pipe.
Never place anything on top of the boiler.
