OIL STORAGE TANKS

Oil storage tanks made of steel and all connecting equipment 

(eg: filling pipes and vent pipes) should comply with B.S. 

799 Part 5. Galvanised steel must not be used. Polyethylene 

(Plastic) tanks should comply with OFTEC standard OFS T100 

and or equivalent. Oil should never be stored in translucent 

plastic containers.
An isolating valve should be fitted at the tank outlet, in an 

accessible position so that the oil supply to the appliance can 

be shut off if required. This isolating valve must be of a type 

suitable for use with oil. (See 

Fig. 9.3

, 

Fig. 9.4

, 

Fig. 9.5

 & 

Fig. 

9.6

).

In order to enable the sediment and water to be removed 

from tanks a drain valve should be fitted. Oil storage tank 

support must be carried out in accordance with the tank 

manufactures recommendations. Tanks should be located 

in the most un-obstructive position possible having taken 

safety, filling, maintenance and the need, if any, to provide a 

head of oil for the burner into consideration.

FUELS

THE RECOMMENDED FUEL IS KEROSENE 28 SECOND 

VISCOSITY FUEL OIL. 

FUEL SUPPLY LINE 

The oil supply line from the oil storage tank to the appliance 

should be of an approved and suitable pipe with a minimum 

internal diameter of 9mm (3/8”) and connected to the oil inlet 

connection located at the cooker left hand side.
Oil supply pipes are normally run in annealed copper tube 

complying to B.S. E.N. 1057. It can be obtained in coil or half 

hard form for use with bending machines. This pipe can 

also be obtained with protective plastic sheathing applied. 

Fittings for copper pipe should be compression of the 

flared manipulative type to B.S. 864: Part 2 1983. Steel pipes 

complying with B.S. 1387: 1985, if used, must be protected 

from corrosion. Galvanised pipe and fittings must not be 

used.
Screwed joints must only be made with tapered threads 

complying with B.S. 1740: Part 1: 1971.
Jointing materials must be of types intended for use with oil 

fuel. Special petroleum – resisting compounds and PTFE tape 

are suitable. External pipes should preferably be run with a 

continuous rise towards the direction of flow, so that one can 

be vented off. It is important to avoid high points which could 

cause air locks.
Exposed lengths of oil supply pipe must be properly 

supported by purpose made clips securely fixed in place. 

Metal clips formed so as to hold the pipe on to a saddle 

are preferred. Consideration should be given to avoiding 

routes which expose the pipe to severe chilling which could 

cause freezing of the oil. Where pipes are buried, they must 

be protected from accidental damage. The use of joints 

underground should be avoided if at all possible. If joints 

have to be fitted in pipes laid below ground, access to them 

must be provided. 
An oil filter (5 - 10 micron) and stop valve must be fitted 

to the fuel feed line and located near the supply tank and 

facilities should be provided to enable it to be serviced 

without draining down the oil supply system. (See 

Fig. 9.3

, 

Fig. 9.4

, 

Fig. 9.5

 & 

Fig. 9.6

).

At the point where the oil line enters the building, the oil 

line must be fitted with an approved 65ºC remote acting 

fire valve, which meets the requirements of B.S. 5410: Part 1, 

fitted with the appropriate length of capillary. The heat sensor 

phial of the fire valve must be fitted to the clip provided in 

the burner compartment. It is absolutely essential that the 

fire valve is located externally and is as close as possible to 

the appliance. For existing installations where the oil supply 

are built into the structure internally, the remote acting 

fire valve should be fitted where the oil supply line is first 

exposed internally. This type of layout is not recommended 

for new installations.
When gravity feed is used (the most common) the minimum 

head should not be below 1 meter (3’3”) and the maximum 

head should not exceed 6.5 meters (21’ 3”).

NOTE

: The pump is factory set for a single pipe installation 

to convert to a two pipe system consult manufacturer’s 

instructions.
Before connecting the oil supply, secure appliance burner oil 

pipes to the base using the T junction (see 

Fig. 9.1

 & 

Fig. 9.2

).

SINGLE PIPE SUPPLY SYSTEM: BOTTOM OF OIL STORAGE 

TANK ABOVE BURNER (See 

Fig. 9.3

)

Single pipe supply system: Tanks servicing this appliance by 

means of a single pipe need to be positioned so that they will 

apply the minimum head required 1 meter (3’ 3”) of oil to the 

burner when the fuel level is at its lowest point.
Refer to B.S. 5410 to calculate the additional head 

requirement relating to pipe length and size.

TWO PIPE SUPPLY SYSTEM: BOTTOM OF OIL STORAGE 

TANK BELOW OR LEVEL WITH BURNER (see 

Fig. 9.4

)

If the tank base is below the level at which the gravity feed to 

the burner can be maintained, a two pipe oil supply system 

may be adopted. (See 

Fig. 9.4

). The non-return valve in the 

supply line of the two pipe system is required to prevent oil 

running back from the burner and unpriming the oil pump. 

The non-return valve in the return line is only required if the 

top of the tank is above the burner. Its purpose is to prevent 

oil running back through the burner during maintenance.

SINGLE PIPE SYSTEM: WITH DE-AERATION DEVICE 

BOTTOM OF OIL STORAGE TANK BELOW OR LEVEL WITH 

BURNER. (see 

Fig. 9.5

):

This system can be used where the tank base is below the 

level at which gravity feed to the burner can be maintained 

and the burner incorporates an oil pump. The chamber is
