1.5 Electrical Connections
Refer to
Figure 3
and
Figure 4
for CFH wiring and cable connections. See also wiring diagram on page 13.
A qualified electrician or service technician must make the electrical connections to the boiler; all local
electrical and building codes should be adhered to.
Refer to wiring diagram provided with the boiler or in the CFH manual. Ensure all required customer
connections are properly made. Main power (115 VAC single phase 60Hz) and any remote wiring should be
brought to the left side of the control panel and terminated at the appropriate terminals provided. Controls for
the boiler feed pump (or feedwater valve if applicable) should be wired to control panel terminals 6 and 7.
