Oil Installation/connection
WARNING
Prolonged exposure and contact
with gas oil can result in the
natural oils being removed from
the skin, sensitisation can result in
dermatitis.
Always ensure that the appropriate
personal protective equipment is used.
Fuel supply
WARNING
Galvanised or plastic pipe work
and fittings must not be used. (See
BS 5410 Part 1)
The constraints of the application will,
to a large extent, determine whether it
is preferable to use a single pipe gravity
feed system, or whether the two pipe
pumped system is more appropriate. Where
more than one appliance is to share a
common supply it will be necessary to use a
pressurised ring main system.
All pipe work must be constructed and
installed so that it does not permit the
ingress of air. The construction, size, and
position of the oil storage tank must take
account of the current regulations, as
well as suiting the requirements of the
installation.
CAUTION
On pumped systems always check
that the pump is correctly set up
prior to operation.
Ensure that valves are open
allowing a free flow of oil through
the system.
In order to promote trouble free operating
it is necessary that the oil within the storage
tank and oil line does not fall below the
cold filter plugging point (cfpp), in the UK
and with class D fuel (also referred to as gas
oil). The critical temperature is -4°C for this
summer grade.
The cfpp critical temperature for the winter
grade is -12°C. If summer grade fuel is
stored for winter use in areas prone to
severe frosts and low temperatures it will
be necessary to insulate or even heat the
supply tank and pipe work.
Note: The fuel supplier should be con-
tacted prior to installation so that any
requirements concerning delivery,
transport, storage and use can be ad-
dressed before work commences.
The inlet pump pressure must not exceed a
maximum of 0.4 bar, this is because beyond
this point gas is liberated from the oil.
Storage tank
An externally painted steel storage tank
to BS 799 part 5 or a medium density
polyethylene oil tank OFTEC certified to
OFS T-100 may be used. Local, national,
European and fire regulations must also be
complied with and must include:
• A fuel level gauge (not made from glass)
a vent pipe with a diameter greater
than that of the filler and featuring a
weatherproof termination.
• A sludge valve.
• An outlet valve situated at the opposite
end of the tank to the sludge valve.
• A filler pipe connection situated at the
opposite end to the outlet valve.
