8. Activating the Pump

NOTE: The CB-3500 and CB-5000 furnaces feature a priming switch which is mounted on the

left-hand side of the electrical junction box on the front of the furnace cabinet. The priming switch has

two positions:

• PRIME (switch is in the UP position / orange indicator light is ON): this is used only

for pump priming. When the switch is in the UP position, the pump circuit is activated for

priming. The pump will continue to run as long as the switch is in this position. The oil

primary control circuit is de-activated so the burner cannot run while the switch is in the UP

position.

• BURNER (switch is in the DOWN position): this is used for normal burner operation.

When the switch is in the DOWN position, the burner controls the operation of the pump.

The pump will only run while the burner is running.

a. Refer to Figure 5B to locate the priming switch.

b. Turn the priming switch to the prime (UP) position. The pump should immediately start running.
