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
Metering Pump Wiring Schematic
in Appendix B at the
back of this manual.
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.
Refer to NFPA-70 for wire size and distances
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.

refer to the "w/Options" breaker size above. Make sure a qualified electrician properly sizes and
installs this electrical circuit.
Refer to NFPA-70 for wire size and distances.
