General Information; Electrical Connection; Routine Maintenance - Worcester 50/70 User Instructions & Customer Care Manual

GENERAL
INFORMATION
To ensure you get the very best from your new Worcester
Bosch oil boiler, please read these notes and instructions carefully.

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.
The mains supply for your boiler is 230/240 volts AC-50Hz.
Your boiler must be earthed and protected by a 5-amp fuse.
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
combustible materials over the boiler or against the flue pipe.
Never place anything on top of the boiler.

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.
