WARNING
• SINGLE PIPE
The pump is designed to allow working with one pipe.
• TWO PIPE
In order to obtain two pipe working it is necessary to unscrew the
return plug (2), screw in the by-pass screw (3) and then screw in
return oil line (2). (See fig. 4).
In the two pipe systems, before starting the burner make sure that
the return pipe-line is not clogged. An excessive back pressure
would cause the damage of the pump seal.
HYDRAULIC SYSTEM
1 - Suction pipe
2 - Return line
3 - By-pass screw
(* is supplied loose in burner pack )
4 - Pressure gauge connection
& Bleed screw
5 - Pressure adjuster
6 - Vacuum gauge connection
7 - Valve
8 - Auxiliary pressure test point
H = difference of level L = Max. length of the suction line
I.D. = Interminal diameter of the oil pipes
PRIMING PUMP:
On the system in fig. 5 it is sufficient to loosen the suction gauge
connection (6, fig. 4) and wait until oil flows out.
On the systems in fig. 6 and 7 start the burner an d wait for the prim in g.
Should lock-out occur pr ior to the arrival of the fuel, await at least 20
secon ds befor e r epeatin g the oper ation . The pum p suction should n ot
exceed a maxim um of 0,4 bar (30 cm Hg). Beyond this limit gas is r eleased
fr om the oil. Oil pipes must be completely tight.
I
n the vacuum systems (fig. 7) the r eturn line should terminate within the
oil tank at the same level as the suction line. In this case a non-return valve
is not required. Should however the return line arrive over the fuel level, a
n o n - r eturn valve is r equir ed. This solution however is less safe than
pr evious one, due to the possibility of leakage of the valve.
