8.2 Fuel Oil Supply

8.2.1 Fuel Storage Tank
The fuel storage tank should be located outside the
building as close as possible to the heater. The tank
must be installed per local and national codes.
8.2.2 Fuel Pipes
The fuel pipes must be sized to ensure an adequate
supply of oil to the entire installation. Galvanised
pipe must not be used for oil installations. The fuel
pipe must terminate at each heater with an isolating
manual valve, a fire valve and a fuel filter. See Page
16, Figure 4. The fusible link of the fire valve should
be installed 100 mm (4 in) above the burner.
The heater's oil burner pump inlet is provided with a
flexible oil line which should be used for the final
connection. When making the final connection to the
heater, do not block any of the removable panels of
the heater. All COMBAT
supplied with burner pumps fitted for one pipe
systems.

8.2.3 Gravity Feed Systems
The simplest installation is a gravity feed system.
This system relies on the head of the fuel to push
the fuel through the system. See Page 16, Figure 4.
8.2.4 B. M. Oil Lifter
Where a gravity feed system cannot be used, a B.
M. oil lifter may be used for small installations up to
the equivalent of a single model 050 on minimum lift
or a single model 020 on maximum lift.
The fuel output from the oil lifter is gravity fed.
The B. M. oil lifter requires a constant 230 V 50 Hz
1 Ø electrical supply. The maximum pipe size to be
used on the suction side is 1/4" ID, 5/16" OD (8
mm). For maximum loading of oil lifters See Page
25, Figure 15. Consult the manufacturer's
information regarding the need to prime these
devices.
8.2.5 Pressurised Systems
See Page 26, Figure 16. For larger installations, a
pressurised system may be used. In this type of
