FUEL SELECTION AND STORAGE
Fuel complying with the characteristics indicated in the burner
user manual or burner vendor catalogues should be obtained.
Fuel transfer lines should comply with technical specifications,
procedure guides and standards in effect. The fuel tank-burner
axis levels should not exceed figures specified in the burner
user manual.
Fuel tanks should conform to standards. A wall must exist
between the fuel tank and the boiler.
If the fuel is oil, the necessary arrangements and heating
system should be installed for fuel flow from tank to burner.

FUEL HARDWARE
In a boiler operation, fuel hardware is quite important. Different
burner hardware exists for various fuels. Automatic systems are
also used for fuel burning. Because the system may
malfunction at any time for any reason during automatic fuel
burning, the operating personnel for automatic burning
controlled boilers should be trained to operate the boiler
manually when necessary and automatic operation should be
continuously monitored by the boiler men and the system
should be transferred to manual mode immediately in
emergencies.
The fuel hardware should be controlled before firing whatever
the fuel type it runs with.
When the boiler is first fired or a burner, which was shut off for
any reason, is restarted, the boiler should be ventilated for at
least 2 minutes to enable purging of flammable gas mixtures
that may have collected in the furnace and chimney gas
channels.
Liquid fuel hardware
In liquid fuel burning boilers, before first firing, all the tank,
heater, pump, valve and pipe system related to the fuel circuit
should be reviewed and ensured that they are in good status
and function normally.
If the liquid fuel tank is at a lower level than the fuel pump,
parts such as valves, flanges, filters should be inspected and
full leakage prevention should be provided in suction pipe; the
pump should thus be prevented from drawing air. When fuel-
oil is used as liquid fuel, all heaters operating with electricity or
steam should be checked to be in good working order. In steam
