1.1
General installation information and advice may be obtained
from the Oil Firing Technical Association for the Petroleum
Industry (OFTEC). Training courses are also offered by OFTEC,
leading to inclusion on their list of registered engineers.
1.2
The appliance should be installed by a competent person. The
person installing the appliance should be aware of the Health and
Safety at Work Act and take appropriate action to ensure that the
regulations are adhered to. In order to give optimum efficiency
and trouble free operation the appliance should be commissioned
by a qualified engineer. OFTEC recommends the use of registered
engineers for the commissioning of oil-fired burners.
1.3
The manufacturers notes must not be taken, in any way, as
overriding statutory obligations.
1.4
The compliance with a British Standard does not, of itself,
confer immunity from legal obligations. In particular the
installation of this appliance must be in accordance with the
relevant requirements of the following British Standards and
regulations in respect of the safe installation of equipment.
BS 5410: part 1& 2: Code of practice for Oil Fired Boilers.
BS 799: part 5: Specification for Oil Storage Tanks.
BS 7593: Code of Practice for treatment of water in domestic hot
water central heating systems.
BS 5449: part 1: Specification for forced circulation hot water
central heating for domestic premises.
BS 5955: part 8: Specification for the installation of
thermoplastic pipes and associated fittings for use in domestic
hot and cold water services and heating systems.
BS 7291: Thermoplastic pipes and associated fittings for hot and
cold water for domestic purposes and heating installations in
buildings.
BS 7074: part 1: Application, selection and installation of
expansion vessels and ancillary equipment for sealed water
systems.
BS 7671: IEE Wiring Regulations, current edition.
The Building Regulations Part J and L1 England and Wales; Part F
and Part J Section III Scotland; Part L and Part F Northern Ireland.

The Control of Pollution (Oil) Regulations.
1.5
To ensure that the installation will perform to the highest
standards, the system and components should conform to those
mentioned in the instructions.
2.1
These instructions cover room sealed balanced flue (RS) appli-
ances only.
2.2
The Worcester Greenstar HE Oil appliance covered in these
instructions has been designed to serve domestic central heating
and hot water requirements ranging from 12 kW to 22 kW.
2.3
This RS balanced flue appliance forms a fully room sealed
system causing the combustion air to be drawn through a duct
from outside. The sealed burner cover gives excellent acoustic
noise reduction and alleviates the need for an air brick to be
located in the boiler room.
Because the balanced flue system does not rely on the cabinet
panels to form the room seal, combustion readings can be taken
from the test point on the condenser heat exchanger and the cabi-
net panels can be easily removed during installation thereby pre-
venting any damage.
2.4
The boiler is factory set to the mid-range output and can be
altered, if necessary, by adjusting the burner as specified in Table
2. This appliance is only suitable for use with 28 second Kerosene
heating oil.
NOTE: It is a mandatory requirement of the building
regulations that only 28 second kerosene is used on low level
discharge flues.
