Fuel Supply: The pumping unit of the burner
is equipped with a self-priming pump capable
of feeding itself within the limits listed in tables
below.
The tank is higher than the pumping unit (A):
The distance “P” must not exceed 33 ft (10 m)
in order to avoid subjecting the pump’s seal to
excessive strain; the distance “V” must not exceed
13 ft (3.94 m) in order to permit pump self priming
even when the tank is almost completely empty.
The tank is lower than the pumping unit (B):
Pump suction pressures higher than 13”Hg for
Suntec oil pump and 15”Hg for Webster 2 Stage
22R oil pump must not be exceeded. This is
because at higher levels, gas is released from the
fuel and the pump starts making noise and its
working life-span decreases.
It is good practice to ensure that the return and
suction lines enter the pumnp from the same
height to reduce risk of priming failure.
