7 OIL SUPPLY
1. Oil Tank
Steel tanks constructed to BS799: PART 5 should be painted on the outside only
and mounted on piers to prevent corrosion. Plastic oil tanks are also available and
can be suitable for installation at ground level. However, oil should never be
stored in translucent plastic containers.
The tank outlet should be at a height to provide sufficient clearance to allow for
proper maintenance of any isolation valve, oil filter or water separator fitted.
2. The pipe from the oil tank to the burner should be run in copper, steel or
aluminium. Galvanised pipe and fittings should not be used. The pipework should
terminate close to the boiler and be fitted with an isolating valve and filter. A
remote sensing fire valve must be fitted to the oil line preferably before the oil line
enters the building (BS5410 : PART 1).
Depending on the position of the tank a two pipe system may be required. One
and two pipe oil systems are shown below. As an alternative to a two pipe system,
a Tigerloop or other approved de-aerator may be used.
7.1 One Pipe Gravity System
Total Maximum Pipe Length (m)
Note: Plastic oil level gauges may shrink
when exposed to kerosene thus allowing
the ingress of water. Pump failures due
to water contamination are not covered
under warranty.
