PUMP PRIMING
- Before starting the burner, make sure that the
tank return line is not clogged. Obstructions in
the line could cause the seal located on the
pump shaft to break. (The pump leaves the facto-
ry with the by-pass closed).
- In order for self-priming to take place, one of the
screws 3)(A) of the pump must be loosened in order
to bleed off the air contained in the suction line.
- Start the burner by closing the control circuit and
with switch 1)(C)p.10 in the "ON" position. The
pump must rotate in the direction of the arrow
marked on the cover.
- The pump can be considered to be primed when the
light oil starts coming out of the screw 3). Stop the
burner: switch 1)(C)p.12 set to "OFF" and tighten
the screw 3).
The time required for this operation depends upon the
diameter and length of the suction tubing. If the pump
fails to prime at the first starting of the burner and the
burner locks out, wait approx. 15 seconds, reset the
burner, and then repeat the starting operation as often
as required. After 5 or 6 starting operations allow 2 or
3 minutes for the transformer to cool.
Do not illuminate the photocell or the burner will lock
out; the burner should lock out anyway about 10 sec-
onds after it starts.
Important:
The priming operation is possible because the pump is
already full of fuel when it leaves the factory. If the
pump has been drained, fill it with fuel through the
opening on the vacuum gauge prior to starting; other-
wise, the pump will seize. Whenever the length of the
suction piping exceeds 66-99 ft, the supply line must
be filled using a separate pump.
