PUMP PRIMING

-
-
The time required for this operation depends
upon the diameter and length of the suction tub-
ing. If the pump fails to prime at the first starting
AJ6 CC
of the burner and the burner locks out, reset the
220
burner, and then repeat the starting operation.

Do not illuminate the cell UV or the burner will
lock out.

N.B.
12
It is advisable to first set the burner for operating
0.15
on oil and then for gas.
D1177 WARNING
Execute the fuel exchange when the burner
is off.
FIRING
Set switch 1)(C) to "ON".
During the first firing, during the passage from
the 1st to the 2nd stage, there is a momentary
lowering of the fuel pressure caused by the fill-
ing of the 2nd stage nozzle tubing.
This lowering of the fuel pressure can cause the
burner to lock-out and can sometimes give rise
D469
to pulsations.

Before starting the burner, make sure that
the tank return line is not clogged.
Obstructions in the line could cause the
sealing organ located on the pump shaft
to break. (The pump leaves the factory with
the by-pass closed).
Also check to make sure that the valves
located on the suction line are open and that
there is sufficient fuel in the tank.
For self-priming to take place, one of the
screws 3)(B) must be loosened in order to
bleed off the air contained in the suction line.
Start the burner by closing the control
devices, with switch 1)(A) in the "ON" posi-
tion and with switch 30)(A)p.4 in the "OIL"
position.
The pump can be considered to be primed
when the light oil starts coming out of the
screw 3)(B).
Stop the burner: switch 1)(C) set to "OFF"
and tighten the screw 3)(B).
