2.5.2 OIL SUPPLY
Note: It is advisable for dual fuel burners, that the ofine fuel is manually isolated with a proof of closure
microswitch that is interlocked with the online control circuit.
e.g. gas supply proof of closure interlocked with the oil burner control circuit. Oil supply proof of closure
interlocked with the gas burner control circuit.

adequate adjustment remaining on the air inlet damper for additional air, and that the exhaust gas
analysis readings are 0 - 10 ppm of CO maximum, with CO2 in the range 9.0 - 10.0 % maximum.

The positioning of the oil storage tank will be dependent on site conditions and local regulations.
The burner fuel pump is of the bypass type requiring the installation of feed and return lines
between the oil storage tank and the boiler. These lines should be in tubing of a minimum bore of
10 mm - 15 mm.
Arevalve,stopvalveandcheckvalvesshouldbeinsertedintheoilfeedline.
Toavoidblockagesinthefuelpumpandburnernozzle,ametalcartridgeoilltershouldbetted.
Fibrouscartridgeltersarenotrecommended.
Thenalconnectionsbetweenthefuelpumpandthefeedandreturnlinesshouldbemadewith
theexiblefuellinessupplied.Iftheoilstoragetankispositionedhigherthantheboiler,anon-
returnvalveshouldbettedtothereturnline.
To overcome suction problems at the fuel pump, all vertical lifts in the feed pipe should be made
as close to the boiler as possible. The burner fuel pump pressure is pre-set at the factory and
should not require adjustment.
