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  installa-
tion  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  expan-
sion 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
Section III and Part J 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.

The 

Benchmark

initiative is the new code of practice

to  encourage  the  correct  installation,  commissioning  and
servicing  of  domestic  central  heating  boilers  and  system
equipment.

The  'Log-book'  is  a  vital  document  that  must  be  completed
by the installer at the time of installation. It confirms that the
boiler has been installed and commissioned according to the
manufacturers instructions.

Without the completion of the Log-book, manufacturers may refuse
to respond to a call-out from a householder, who will be advised
that he or she must call back the installer, who has not fulfilled his
obligations to record the information required by the initiative.

It is important that:

The services and the system are properly flushed as specified.
The User is clearly instructed on the correct operation of the
appliance.
The benefits of regular servicing are explained - to maintain the
efficiency and extend the life of the appliance.

2.1 

These instructions cover both conventional flue (CF)/low-level

discharge (LLD) and room sealed balanced flue (RS) appliances.

2.2 

The Worcester Danesmoor range of appliances covered in

these instructions have been designed to serve domestic central
heating and hot water requirements ranging from 12 kW to 25 kW.

2.3 

The  RS  balanced  flue  appliance  forms  a  fully  room  sealed

system  by  surrounding  the  burner  with  a  unique,fully  sealed,
push  fit  box.  This  causes  the  combustion  air  to  be  drawn
through a factory sealed air duct formed at the rear and under-
side  of  the  boiler.  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 flue outlet plate as on a conventional appliance, and the
cabinet panels can be easily removed during installation thereby
preventing 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 Tables
2 to 4. The low level discharge and room sealed models are 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. 
2.5 

The  conventional  flue  15-19  and  20-25  models  may  be

converted to burn 35 second gas oil by changing the nozzle and
burner settings as specified in Tables 3 and 4.

2.6 

A colour coordinated twin channel programmer can be fitted

to the appliance facia panel. This is available from Worcester Heat
Systems as an optional extra.

2.7 Principle appliance components. See Figs. 2 and 3.
Oil Fired Burner

A  fully  automatic  oil  fired  pressure  jet  burner  is  used  to  supply
heat  to  the  boiler.  The  burner  can  be  set  to  the  output  require-
ments as detailed in Tables 2 to 4.

Pump

An integral circulating pump is incorporated within the appliance
casing. The pump speed may be altered to suit the heating load by
