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 national 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

WARNING: A fuse-protected disconnect must be mounted in a readily accessible location for

the installation of the unit. This device can also be used for a disconnect in case of an

emergency.

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. Ensure that the ground

wire is attached to the green ground screw on the furnace junction box.

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.

CB-2500 230 15 amps Dedicated 50

*NOTE: When installing any optional equipment (e.g. air compressor or draft inducer), you do

not need to "upgrade" the fuse protection. The fuse size listed above is sufficient. Make sure a

qualified electrician properly sizes and installs this electrical circuit. 14-gauge copper wire is

required for 15 amp fuse protection.

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 using approved

electrical conduit.

2. Wire the pump circuit according to the Metering Pump Wiring Schematic in Appendix B at the

back of this manual.
