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 system s in fig. 6 and 7 start the burner and wait for the priming.
Should lock-out occur prior to the arrival of the fuel, await at least 20
seconds before repeating the operation. The pump suction should not
exceed a maximum of 0,4 bar (30 cm Hg). Beyond this limit gas is released
from the oil. Oil pipes must be completely tight.
In the vacuum systems (fig. 7) the return 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
non-return valve is required. This solution however is less safe than
previous one, due to the possibility of leakage of the valve.
