Bosch GREENSTAR II HE OIL 12/22 Service Manual download pdf (Page 2)

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.

Local water company bye-laws.

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.
