5.13.2 Priming pump
Before starting the burner, make sure that the tank
return line is not clogged.
Obstructions in the line could cause the sealing
WARNING
organ located on the pump shaft to break.
In order for the pump (Fig. 23) to be able to self-prime, the
screw 4) must be loosened to purge the air in the suction
line.
Start the burner by closing the remote controls. As soon as
the burner starts, check the direction of rotation of the fan
blade.
The pump can be considered to be primed when the light oil
starts coming out of the screw 4).
Close the burner and undo the screws 4).
The time required for this operation depends upon the diameter
and length of the suction tubing.
If the pump fails to prime at first start-up and the burner locks out,
wait approx. 15 seconds, reset the burner, and then repeat the
start-up operation. And so on.
After 5 or 6 starting operations allow 2 or 3 minutes for the trans-
former to cool.
Do not illuminate the QRI cell or the burner will lock out; the burn-
er should lock out anyway about 10 seconds after it starts.
The above-mentioned operation is possible be-
cause the pump is already full of fuel when it
leaves the factory.
WARNING
If the pump has been drained, fill it with fuel
through
4)(Fig. 23) prior to starting; otherwise, the pump
will seize.
Whenever the length of the suction piping ex-
ceeds 20-30 meters, the supply line must be filled
using a separate pump.
