INSTALLATION INSTRUCTIONS
2. INTRODUCTION
The Contractor H.E. Extenal boiler has been designed to
conform to European Directive/Standards BED 92/42 EEC
LVD 73/23/EEC EMC 89/336/EEC.
The boiler design incorporates a secondary stainless steel
heat exchanger, which recovers heat from the flue gases
which would normally be lost when using conventional oil-
fired boilers.
The matched pressure-jet burner is exceptionally quiet in
operation and ensures clean and efficient combustion, with
low NOx emissions.
The boiler is suitable for all normal open-vented central
heating and indirect hot water systems. The boiler can also
be used with sealed systems up to a working pressure of 3
bar, with the appropriate sealed system safety equipment.
One return and two flow sockets are provided to facilitate
connection to the heating and hot water systems.
To ensure that the boiler is operating at maximum efficiency,
the central heating return temperature should be 50°C or
above. Maximum performance will be achieved by
maintaining a differential of 20°-30°C between the flow and
return water temperatures.
Due to the high efficiency of this range of boilers, and to
comply with Building Regulations, Part L, it is essential that
the appliance be fitted on fully-pumped systems only.
All servicing can be carried out from the front of the boiler.
The front-mounted flue-cover permits easy access for
removal of the baffles and cleaning of heating surfaces.
The boiler is fully automatic in operation and incorporates all
necessary safety controls to ensure safe and reliable
running.
The Contractor H.E. External boiler is supplied with the burner
set for 28 sec. Kerosene Class C2 to BS 2869 fuel to meet the
Building Regulation requirements for low-level flue discharge.
FLUSHING AND WATER TREATMENT
The performance of the appliance could be impaired by system
debris or the effects of corrosion. New systems must be
thoroughly flushed to remove metal filings, solder, machining oils
and any other fluxes or greases before connecting the boiler.
When fitting the appliance to an existing system, it is advisable to
clean the system by using an appropriate flushing and descaling
agent. Refer to BS 7593 [1992] for guidance.
System additives - corrosion inhibitors and all flushing
agents/descalers should be suitable for steel boilers and comply
with BS 7593 requirements.
Always refer to manufacturers' instructions.
Failure to flush and add inhibitors to the system will
invalidate the appliance warranty.
The appliance is designed to be fitted to fully-pumped
systems only. Failure to do so will invalidate the
warranty.
The boiler must not be run without water in the
system.
IMPORTANT NOTICE:
To comply with regulations in force, the boiler must be installed and commissioned by an
OFTEC -registered engineer. The installation must comply with all requirements of current
Building Regulations, Part L.
Failure to meet the terms of these requirements may invalidate the guarantee.
THE PERSON(S) WHO INSTALLS THIS APPLIANCE, SERVICES OF CARRIES OUT ANY
REMEDIAL WORK, i.e. ELECTRICAL FAULT-FINDING, MUST HAVE THE SUITABLE
ENGINEERING QUALIFICATIONS.
