Electrical Connections - CleaverBrooks CFC Operation, Service & Parts Manual

I. ELECTRICAL CONNECTIONS
A qualified electrician or service technician must make the electrical
connections to the boiler.
For typical CFC electrical component mounting see the electrical
diagram mounted on the inside of the removable front panel.
For specific information on your boiler electrical system refer to the
Cleaver-Brooks wiring diagram provided with the boiler.
Power is to be run from the rear of the boiler through either the left
or right electrical supply channels (see Figure 2-38) to the control
panel. AC power is to be connected to the incoming power
terminals.
1. Power wiring - right side electrical supply channel.
2. Customer connections should be brought in on the right side -
refer to wiring diagram.
3. Temperature sensor wiring - left side electrical supply channel.
Note: The following temperature sensor cables should be run
through the left side wiring channel.
• Hot water outlet temperature sensor.
• Hot water return temperature sensor.
• Stack temperature sensor (optional).
• Outdoor temperature sensor (optional).
The blower signal wiring must be isolated from the blower power
wiring and the high voltage ignition cables.
Ensure ignition cables are properly connected and not in direct
contact with any sharp metal edges.
For electrical connections see Figure 2-38.
