COMMISSIONING
Remove the electrics panel cover to allowing access to the power supply cables
and boiler thermostat cables via the cable entry unions. Connect the cables as per
the wiring diagram (see page 21 and 22). These connections are of split type, and
will allow you to connect the phase leads to terminals L1, L2 and L3 and the
ground lead to terminal N. Connect the earth wire to the point indicated with a
grounding mark, boiler thermostats to terminal BT and the safety thermostat to
terminal ST. Then re-assemble the electric panel cover.
FUEL PUMP
FUEL HOSE CONNECTION
Fuel hose connections are made by two G1/2. threaded connections. Both
suction and return connections use the same connection types. The following
picture shows the suction and return sides of the oil pump where the oil hoses
are connected (Figure 20).
PRINCIPLE OF OPERATION
The gear set draws oil from the tank through the built-in filter and transfers it via
a valve that regulates the oil pressure to the nozzle line. Any excess fuel returns
to the tank. The pump must be free of any leakage, and bled prior to the burner's
operation.
