5. OIL SUPPLY
OIL
The burner is factory-set to burn 28 sec. Kerosene Class C2
to BS 2869.
Trianco makes no guarantee as to the satisfactory operation
of the boiler using fuels other than that which is stated
above.
STORAGE TANK
The tank should be fitted with weather-protected fill and vent
connections, a drain-off cock, and an oil level indicator.
Size and Location of Tank
The tank should be large enough to allow for economic
deliveries and be located in an unobtrusive position, having
regard to the need for safety, filling, maintenance, and head
of oil required (see Fig. 11).
Steel Tanks
Steel tanks must comply with the requirements of BS 799
Part 5: 1987 and should be mounted on brick or block piers,
with a waterproof membrane fitted between the piers and
tank.
Plastic Tanks
Polyethylene tanks may be used, having several advantages
over traditional steel tanks:
(a) Pier supports are not required; the tank may be fitted
directly onto a flat surface.
(b) They do not corrode; therefore never require repainting.
(c) They are easier to handle because of lower weight.
(d) They are supplied with a 10-year manufacturer’s
guarantee.
Fire Protection
Whilst it is highly unlikely that a fire could start from a
domestic oil tank, protection is required from a fire which
may originate elsewhere. The tank should be at least 1.8
metres from a building and 750mm from a site boundary.
Where it is not feasible to adhere to these limits, the building
wall must not have any openings other than those for
ventilation, the wall must have at least a half-hour resistance
to fire, and must extend 1.8 metres from any part of the tank.
Alternatively, a non-combustible radiation barrier can be
employed, which meets all the requirements of BS 5410 Part
1. This standard applies to tanks up to a capacity of 3,500
litres.
See current OFTEC regulations for further details.
To comply with Building Regulations, section J5:
1. Where the tank is close to a dwelling, fire protection must be
provided to the eaves, if less than 1.8 metres from the top of
the tank.
2. Cladding must extend at least 300mm beyond the tank.
3. The tank must be fitted on a non-combustible base.
Pollution Protection
To comply with Building Regulations, section J6, the tank must
be bunded (double-walled) if:
1. The tank is less than 10m from a stream
2. The tank is less than 50m from a well, spring, or other
source of drinking water.
3. The tank cannot be viewed from the point of delivery.
4. There is risk of oil reaching a manhole cover or drain in the
event of a leak.
5. The tank capacity exceeds 2,500 litres.
SUPPLY
A long-life flexible oil hose is supplied with the boiler. A filter and
shut-off valve are also required. These should be fitted as shown
on Figs. 11, 12, & 13.
All oil line joints must be completely sealed and the total pipe run
should be flushed thoroughly before connection is made to the
burner. No soldered joints are permitted in the oil line.
Fire Valve
A remote-operated fire valve must be fitted in the oil supply line,
externally to the premises, with the sensing phial located at a
point above the burner.
To comply with OFTEC regulations, a CD/10 form must
be completed and left with the appliance upon
