• Cable: PVC insulated 0.75 mm2 (24 x 0.2mm) temperature rated to
90°C.
• Circuit breaker incorporating earth leakage protection.
• External 5A fuse to BS1362.
• The appliance must be earthed.
• This appliance must not be connected to a three phase supply.
• Wiring must comply with the latest IET wiring regulations.
• It must be possible to isolate the appliance from the electrical supply
with at least a 3mm contact separation in both poles supplying the
appliance.
• Wiring between the appliance and the electrical supply must comply
with IET wiring regulations and any local regulations that may apply
for fixed wiring to a stationary appliance.
• Any system connected to the boiler must not have a separate

4.3 Oil supply
• This appliance is suitable for Kerosene (Class C2) only, no other
fuel must be used.
• Plastic or steel tanks must be installed to BS 5410.
A steel tank should conform to BS 799: part 5 and have a slope of
1:24 away from the outlet with a sludge cock at the lower end.
• Do not use galvanised steel tanks or pipework for the oil system.
• Do not use soldered joints on the oil supply pipework.
4.3.1 Single pipe gravity feed system:
The oil storage tank [1] must be positioned so that the oil level does not
exceed 4 metres above the level of the burner oil pump [9] and in
addition the oil level must be at least 300mm above the oil pump [9].
Where the maximum oil level in the oil storage tank exceeds 4 metres, a
head breaking device must be installed between the tank [1] and the
burner oil pump [9].
