ROOM-SEALED BALANCED FLUE
BOILERS
Air for this type of boiler is supplied via the balanced flue
terminal, 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. The internal fuse is a 3- amp, 20mm quick-blow fuse.
ELECTRICAL CONNECTION
A mains cable should be connected to a double pole isolator
with a contact separation of 3 mm on all poles and supplying the
appliance and controls only.
Your boiler must be earthed and protected by a 5-amp fuse.
ROUTINE MAINTENANCE
It is essential that your boiler is installed and serviced by a
competent heating engineer, and Worcester Heat Systems will be
pleased to arrange regular servicing and a comprehensive
maintenance contract.
Alternatively, the Oil Firing Technical Association for the
petroleum industry (OFTEC) will gladly advise you of engineers
trained by and registered with OFTEC.
Servicing should be carried out at least once a year for boilers
which burn 28-second kerosene, and twice a year for boilers which
burn 35-second gas oil.
When considering additional controls or fittings for your new
Heatslave hot water and central heating system, please note the
following:
ROOM THERMOSTAT
It is recommended that a mains voltage room thermostat is
fitted, as this will improve your control of room temperatures.
THERMOSTATIC RADIATOR VALVES
Any thermostatic radiator valves fitted to your central heating
system must conform to BS 2767/10.
