5. OIL SUPPLY
Note:
The oil burner is factory set to burn 28 sec.
Kerosene.
Note: Only Kerosene is permitted for low level flue
discharge.
Oil Storage Tanks
The tank must not be installed within 3 metres of the boilers
terminal.
Size and Location of Tank
The tank should be large enough to allow for economic
deliveries and be located in the most unobtrusive
position, having regard to the need for safety, filling,
maintenance (if steel tank) and the head of oil required.
Whilst it is highly unlikely that a fire could start from a
domestic oil tank, it does however need to be protected
from a fire that may originate in a nearby building,
therefore the tank should not be located nearer than 1.8
metres from a building, nor closer than 760mm from a site
boundary. Where a tank has to be less than 1.8 metres,
the building wall must not have any openings other than
small ventilation openings. The wall shall have a half
hour resistance to an internal fire and extend 1.8 metres
from any part of the tank.
Alternatively, a non-combustible radiation barrier must be
provided which meets the requirements of BS 5410 Part
1: This standard applies to tanks up to a capacity of
3,400 litres which is deemed the maximum size for a single
family dwelling.

CABLE FIXING
Warning - High and Low Voltage
In certain parts of the country, where there is a known risk
of high or low voltage fluctuations, the oil burner shall be
prevented from starting by the use of a voltage sensitive
device if the voltage drops or increases sufficiently to
endanger the installation.
Thermostats
The boiler is fitted with a variable setting control
thermostat and a pre-set limit thermostat. Should the
boiler thermostat malfunction, the limit thermostat will
take over control and shut down the boiler.
Frost Protection
The boiler is fitted with a frost thermostat, which will
activate the burner should ambient temperature fall to
5ºC, the thermostat will automatically cut off on temper-
ature rise. There is no manual adjustment.
If the system is shut down for a long period during very
cold weather, it is advisable to completely drain the sys-
tem. However, frequent draining should be avoided,
especially in hard water areas, as this could lead to
scaling of the boiler waterways.
Electrical Supply
230V 1 Phase 50Hz (Fused 5 Amp)
Note: THIS APPLIANCE MUST BE EARTHED
All electrical wiring must be carried out by a qualified
electrician in accordance with current I.E.E. Regulations
and any Local Regulations that may apply.
The 230v - 50Hz electrical supply must be fused by a
double pole switch with a contact separation of at least
3mm in both poles, and shuttered socket (both complying
with the requirements of BS 1363) adjacent to the boiler.
Fuse supply at 5A. The minimum requirement for the
power supply cable should be a PVC sheathed flexible
cord, at least 0.75mm
2
(24x0,2mm) (code designation
H05 VV-F or H05 VVH2-F) as specified in table
16 of BS 6500.
This appliance MUST be earthed and the electrical
supply earth cable must be of a greater length than the
current carrying conductor cables (ie live and neutral
supply cables).
All external cables entering the control box must be
secured in position by strain relief bushes supplied (see
diagram on how to secure cable).
Terminal connections are also provided in the control
panel for ancillary controls.
