Electrical shock hazard - can
cause injury or death. Disconnect
power before installing or servicing.
Provide ground wiring to the burner in
accordance with the National Electrical
Code.
Wire the burner
Install the burner and all wiring in accordance with the
National Electrical Code and all applicable local codes or
requirements.
Wire the burner in compliance with all instructions provided
by the appliance manufacturer. Verify operation of all controls
in accordance with the appliance manufacturer's guidelines.
See Figure 10 for a typical wiring diagram, with R8184 oil
primary, for reference purposes only. The CF2300A burner is
available with many different wiring configurations. Refer to
the wiring diagram shipped with the burner for the actual
wiring applying to your burner.
NOTE: The wiring in Figure 10 is for an R8184 primary
control and a type B fuel unit (using internal by-pass pressure
regulator as shown in Figures 8c and 9c ). The difference in
fuel units is the connection of by-pass oil valve S2 to the
damper-motor end switch. When using a type H fuel unit, the
by-pass oil valve wire is connected to terminal “ W ” instead of
terminal “ B ” on the end switch because the by-pass pressure
regulation is external to the fuel unit.
Do not by-pass any safety control.
By-passing a safety control could result in
severe personal injury, death or substantial
property damage.
