Example: From the chart we can see that a ¾” line that is 80’ in length can supply
118,000 BTU/hr.
10. Oil Supply
a) The oil supply piping to the boiler must be appropriate to local conditions
and must be constructed and installed in compliance with appropriate
Codes and Standards. It should be of sufficient size to satisfy the
pressure and volume flow requirements of the burner under all firing
conditions. Checks should be made to ensure that all meters and
other components are appropriately rated for the maximum oil flow
rate anticipated. Galvanized steel pipe should not be used. The supply
piping should include an appropriate filter.
b) A two-pipe system must be used between oil storage tank and the
burner. One for oil supply and one for oil return. A circulating oil pump is
required to deliver fuel oil at 1-3 psig from the storage tank to the burner.
A oil filter must be installed before the oil-circulating pump,
recommend less than 60 Mesh.
c) The final connection to the oil pump inlet should be made using the
flexible pipes supplied with the burner.
d) One gate valve should be installed to the inlet and outlet of the
circulating pump separately. A pressure gauge (0-60psi) should be
added to the outlet.
e) It is important to ensure that the return pipe is not obstructed as this
may result in damage to the pump.
f) In the case of heavy oil (No.4, No.5, and No.6 oil) the piping and oil
storage tank should be insulated, trace heated and thermostatically
controlled.
11. Installation Check Points-Refer to the details in the BURNER section
a) Make sure that all piping connections are complete and tight.
b) Make sure the pressure controls are adjusted properly.
c) Make sure all electrical connections in the control box, the water column,
and elsewhere are secure.
d) Make sure there is adequate boiler room ventilation. Combustion air
contaminates can cause damage to the boiler jacket and burner.
e) Before operating pumps, metering heads and compressors, make
certain that reservoirs are properly filled with the specific lubricant.
