8. Activating the Pump
NOTE:
The coil tube boiler features a priming switch which is mounted on the left-hand side of
the electrical junction box on the hydraunics side of the boiler 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 UP position. The pump should immediately start running.
