ANCILLARY PUMP (see BT
8666/3)
In some cases (excessive distance,
difference in level or high viscosity),
it is necessary to install a "loop-type"
supply system with an ancillary
pump, which dispenses with con-
necting the burner pump directly to
the cistern.
In this case, the ancillary pump can
be put into operation when the bur-
ner is started up and cut off when
it stops.
The electrical connection of the an-
cillary pump is made by connecting
the coil (30 V), which controls the
pump's relay, to terminals "N" (the

motor's relay).
It is important to comply strictly with
the following provisions:

The ancillary pump must be
installed as near as possible to the
fuel to be sucked.
-
The head should suit the
system in question.
-
We recommend an output at
least to that of the burner's pump.
-
Connection pipes should be
of a size to cope with the output of
the ancillary pump.
