If there is no pressure, determine the cause and correct it before proceeding. Check for obstructions in the air
inlet line, incorrect rotation (remember, air pump rotation is clockwise), or a loose oil nozzle or other leaks. If the
pressure is much higher without any oil flow, check for obstruction in the discharge line or at the oil nozzle.
The air pressure will increase when an oil flow exists. At low firing rate, the air pressure may rise to 12 psi or
more.
After air flow has been verified, turn the burner switch off and return the run/test switch to the “run” position.
5.5 — Firing Preparations for No. 2 Oil (Series 100-200)
Prior to initial firing, oil flow and pressure should be established and
verified. Atomizing air pressure should also be established as outlined
in Section 5.4. The schematic flow diagram in Chapter 2 indicates
the flow of fuel and atomizing air.
If the burner is a combination fuel model, be certain that the main
gas shutoff cock is closed and set the gas/oil selector switch to “oil.”
Insert the burner drawer gun into its most forward position and latch
it in place, closing the oil drawer switch.

If the oil supply tank is located above the level of the pump and flow to the pump is by gravity, then it will usually
be necessary to vent the suction line to allow oil to fill the line. Venting the suction line can generally be accom-
plished by cracking a union fitting, or by opening the cap of the oil strainer using care to prevent spillage of oil.
Tighten the fitting or the cap as soon as oil flow appears.
If the oil supply tank is below the level of the oil pump, it is mandatory that the suction line to the pump be com-
pletely filled with oil prior to starting the pump to avoid the possibility of damage to the pump gears. Non-lubri-
cating fluids such as kerosene should not be used for priming.
Prior to priming the suction line and the initial start, check to make certain that all plugs, connections, etc., have
been securely tightened to prevent leaks.
If the fuel oil supply originates from a pressurized loop, it is assumed that the pressure of the loop will be at a
minimum of 75 psi. Under these conditions, the relief valve at the terminal block should be adjusted to the point
NOTE: Abnormally high pressure indicated on the nozzle air pressure gauge is an indication that the burner nozzle
has become clogged. In the event of clogging, check the nozzle and clean as necessary.
The air pressure should not exceed 35 psi at high-fire. Greater air pressure causes excessive wear of the air pump,
increases lube oil usage, and can overload the motor, thus causing damage to the equipment.
