Wiring the Furnace and Pump
WARNING: To avoid electrical shock, make sure that power to the furnace is turned OFF
before connecting any wires. A licensed electrician should install all wiring to your furnace. All wiring
must be in accordance with the National Uniform Electrical Code and local codes. Properly size all wires and
use electrical conduit for all electrical lines.
Wiring your furnace involves the installation of two lines:
(1) A dedicated electrical line to the furnace
(2) A pump electrical circuit from the furnace to the metering pump
Necessary wiring specifications are provided in this section and in the Wiring Schematics located in
Appendix B at the back of the manual.
Wiring to the Furnace
1. Install a dedicated electrical circuit to the electrical junction box on the furnace.
WARNING: DO NOT tie into an existing circuit, or electrical overload may occur.
2. Wire the furnace according to the Wiring Schematic, Figure B1, in Appendix B.
3. Check for correct voltage at the furnace, and refer to the following chart.
ATTENTION: Incorrect voltage will severely damage the blower motor/furnace components.
DO NOT operate your furnace on any non-specification power system.
Model Voltage Breaker Size* Circuit Hertz
CB-1400 110/120 20 amps Dedicated 60
*NOTE: Breaker size with optional equipment is 30 amps. When installing any
optional equipment (e.g. air compressor or draft inducer), you must use a 30 amp breaker. Make
sure a qualified electrician properly sizes and installs this electrical circuit.
4. DO NOT turn on main power until instructed to do so.
Wiring to the Metering Pump
WARNING: DO NOT wire the pump directly into your building's electrical system. The pump
must be activated (receive power) from the burner via the pump electrical circuit. DO NOT wire the
pump directly to a wall outlet so that it runs continuously; this will seriously damage your metering pump and/or
furnace and may result in a fire or explosion hazard.
1. Install the pump electrical circuit from the furnace to the metering pump location.
2. Wire the pump circuit according to the appropriate Wiring Schematics, Figures B1 and B4
(Appendix B).
