Conversion of Faber Burners from Burning No. 6 Fuel Oil to Burning No. 2 Fuel Oil

The conversion of an existing Faber Burner that presently fires No. 6 fuel oil to fire No. 2 fuel oil is relatively straightforward and simple. No. 6 fuel oil requires preheating of the oil due to its higher viscosity, and it also offers some lubricating properties for the fuel oil pumps. No. 2 fuel oil does not require any preheating and is fired at an ambient temperature. NOTE: (If the No. 2 fuel is stored above ground in a cold climate, some heating may be required in order to keep the fuel oil from becoming a gel at very cold temperatures).

The following items are necessary to accomplish the conversion from No. 6 fuel oil firing to No. 2 fuel oil firing:

  1. Ensure that the fuel oil pumps, in the system are satisfactory for pumping No. 2 fuel oil and, if so, verify the pumps capacity and pressure output when pumping No. 2 fuel oil. NOTE: (Normally, a pump designed specifically for No. 6 fuel oil cannot be utilized for No. 2 fuel oil due to the lack of lubricating properties of No. 2 fuel oil. Some pumps are designed for either fuel; however, the pumping capacity while on No.2 fuel oil will be reduced as compared to No. 6 fuel oil).
  2. The strainer baskets in the fuel oil pump set should be 1/16″ diameter holes. NOTE:(Due to the cleaning properties of No. 2 fuel oil, any deposits left over from the No. 6 fuel oil will very likely be cleaned away from the tank and piping wall. Therefore, it is advisable to circulate the No. 2 fuel oil through the strainers and back to the tanks for a time period as determined by how dirty the strainers become).
  3. Since the No. 2 fuel oil does not require preheating to burn, the temperature limit switches on the burner assembly must be either removed and a wire connected between the two terminals or the switches can be left in place and a jumper wire put between the two terminals to bypass the switches.
  4. A new oil gun assembly with insulated inner-barrel is required. New tips and plugs for the oil gun are not specifically required. However, if the existing tips and plugs have any wear, it is advisable to buy a completely new insulated oil gun with new tip and plug.
  5. A new orifice bushing for insertion in the burner assembly insert is required. This orifice bushing screws into the existing insert.
  6. Tune the burner assembly after the switch-over to No. 2 fuel oil to ensure optimum performance and efficiency from the burner. A burner service engineer is available from the Faber Burner factory in Lock Haven, Pennsylvania, to accomplish this tuning.

In order to maintain optimum performance and efficiency from the burner/boiler assembly, yearly tune-ups are recommended.
