10.6 Pump
The pumps are equipped with a by-pass that separates return line and suction line.

WARNING!
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 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
approximately 15 seconds, reset the burner, and then repeat the starting operation as often as
required After 5 or 6 starting operations, then allow 2 or 3 minutes for the transformer to cool.
IMPORTANT NOTE:
The priming operation is possible because the pump is already full of fuel when it leaves the
facto-ry. If the pump has been drained, fill it with fuel through the opening on the vacuum meter
prior to starting; otherwise, the pump will seize.
Whenever the length of the suction piping exceeds 66 - 98 ft., the supply line must be filled
using a separate pump.
