wiring schematic provided in Appendix B at
the back of the manual.
Installing the Fan Brace
(CB-1800 and CB-2800 only)
NOTE: These instructions apply to Unit Heater Models
CB-1800 and CB-2800 only. Unit Heater Model CB-1400
does not require a fan brace.
1. Refer to Figure 3E.
2. Hook the fan brace end with the larger
loop over the fan guard strut.
3. Check that the fan brace lines up with the mounting
tab on the fan motor.

held firmly in place by the fan brace to prevent fan
vibration. DO NOT over-tension the motor.
