OIL SUPPLY
23
The boiler burner is factory set to use 28-second kerosene. However, Gas oil
35-second can be used with a conventional flue installation if a
PRE-HEATER is also fitted. Note: Gas Oil 35sec may not be used
with a balanced flue installation.
If boiler location allows use of 35 sec.Gas Oil, pump pressure should be
increased and air settings readjusted as necessary. This adjustment should
be carried out by qualified persons only.
5-A Oil Storage Tank Siting
Consult OFTEC Manual
It is very unlikely that a fire should start from a domestic oil tank,
however it does need to be protected from a fire which may originate
in a building nearby. For this reason, the tank should be located at least
1.8 metres from any building and no closer than 760mm from any
boundary. If it must be closer than 1.8 metres, the building wall
should not have any openings other than ventilation openings. In addition,
the wall should have a half hour resistance to an internal fire and
extend 1.8 metres from any part of the tank.
A non-combustible radiation barrier is an alternative but this must meet the
requirements of BS 5410 Part 1: 1994, “clause 28” Section 6.4.
Steel tanks must be mounted on brick or block piers with a waterproof
membrane between the piers and tank.
Polyethylene tanks do not need pier supports and may be mounted on any
flat surface which can support the weight of the tank and its contents. They
also do not corrode and never require painting.
Oil storage tanks should not be sited close to boiler flue outlets.
Do not allow household waste or hot ashes container in vicinity of oil
storage tank or boiler flue outlet.
5-B Flexible Oil Pipe(s)
A flexible burner oil hose is supplied with the boiler.
Please note: A filter must not be fitted inside the boiler and all joints in
the oil line must be oil-tight. Soldered joints are not permissible.
Before connecting to the boiler always flush the complete oil supply
line and ensure that oil supply is completely clean and free of any dirt
or foreign matter.
5-C Single Pipe System
Where installations have the bottom of the tank above the oil burner, a
single pipe system may be used.The oil burner should then be set for single
pipe operation - See
