OPERATING INSTRUCTIONS
Before Operating System
• Furnace door is closed and properly
latched.
Before operating your heating/cooling system
(see Figure 1), make sure that:
Refer to the owner’s manual supplied with the
optional heat pump or air conditioner for further
information.
• Control panel covers are closed.
• Blower and/or relay control plugs are
plugged in.
• Fan switch is set to “AUTO” (E3EH units
only).
CAUTION:
For optional A/C or H/P systems,
always wait at least five minutes after
the system shuts off before restarting
the system. Observe this procedure
when operating the system per the
following instructions.

Overview of E3 Furnace
E3E(-) Series electric furnaces are available in
twomodels.E3EHmodelsareequippedwiththe
standard two-speed blower. E3EH models can
beeasilyconvertedforusewithNORDYNEsplit-
system air conditioners and heat pumps. E3EB
models are air-conditioning ready; that is, they
are equipped with a multi-speed (four-speed)
blower, blower relay, and cabinet insulation kit.
SeeTable3forcoolingandheatpumpavailability
with factory installed blower.
OPTIONAL AIR CONDITIONER
AND HEAT PUMP
Your E3 Series electric furnace is approved for
use with an optional central air conditioner or a
heat pump. To adapt this heating appliance to
a “total comfort system,” contact your nearest
NORDYNE distributor.
Optional air conditioners and heat pumps are
listed by Underwriters’ Laboratories (UL) or
Environmental Testing Laboratories (ETL) and
certified by ARI and the Canadian Standards
Association(CSA),orWarnockHerseyorETLC.
These cooling systems include energy-sav-
ing components to provide maximum cooling
performance at electrical energy usage levels
established by federal standards. Refer to the
operation instruction label on your furnace for
theoptionalairconditioningequipmentapproved
for your heating appliance.
Fortypicalunductedreturnairdownflowapplica-
tions,anair-conditionerorheat-pumpcoilcanbe
installed by mounting the coil directly on top of
the furnace without adding sheet metal cavities
or cutting and trimming wood panels.
Areturnairgrilleforclosetoralcoveinstallations
is available. For downflow alcove installations,
the grille (with frame provided) may be attached
to the top of the furnace and all paneling and
trim flushed to it. This installation provides an
access door for future installation of NORDYNE
air conditioning or heat pump coils on top of
the furnace.

Thefollowingstepsdescribeinstallationinstruc-
tions for an under-the-floor supply duct system
with a return air system that can be either
unducted or ducted. Duct connectors (Table 4)
are recommended for this application.
NOTE:Beforeinstallingthisfurnace,considerall
clearancesfortheinstallationandfutureservicing
of the furnace. Refer to Table 1.
Closed-Off Space Requirements
Return Air and Filtering Systems
Living space not served by, and closed off from,
thereturnairductstothefurnacebydoors,sliding
partitions, and other means must be provided
with permanent, uncloseable openings in the
doors or partitions to allow air to return to the
furnace from all parts of the home. Return air
grilles, with a minimum open area of one square
inch for every five square feet of living space
closed off from the furnace, must be provided
in the door or room partition.
Furnaces may be installed with unducted or
ducted return air. For unducted return air
systems, either the optional grille and frame
assembly or the optional wall mount grille is rec-
ommended. For ducted return air systems with
air conditioners or heat pumps, either providing
an access panel in the duct or using the optional
coil cabinet is recommended. The duct system
must be properly sized so as to account for any
additionalexternalstaticpressureproducedfrom
the chosen filtering method.

Installing Duct Connector
NOTE: The duct connector is designed for use
on ducts down to 12” wide. On typical ducts,
the finger tab duct connector may be installed

IMPORTANT:
Note:Circuitbreakersinstalledwithin
this unit are for short-circuit
protection of the internal wiring
and to serve as a disconnect. Circuit
breakers installed within this unit DO
NOT provide over-current protection
ofthesupplywiringandthereforemay
be sized larger than the branch circuit
protection.
NOTE: To install single-circuit kit, perform
step 5. If single-circuit kit installation is not
necessary, go to step 6.
5. To install single-circuit kit:
a. Loosen lugs at supply side of circuit
breakers.
b. Remove cover from single-circuit kit (if
supplied).
c. Insert metal buss bars of kit into lugs of
circuit breaker.
d. Tightenlugssecurely(45in.-lbs.recom-
mended).

one side, one on the other) and the long tab
in the rear.
6. Replace screws previously removed from
blower.
7. Connect the motor plug to the control panel
receptacle.
8. Switch circuit breaker(s) to “ON”, reinstall
furnace front door, and turn on electrical
supply circuits to the furnace.
WARNING:
To avoid personal injury or property
damage, make certain that the motor
leads cannot come into contact with
non-insulated metal components of
the unit.
Selecting Blower Speed
See Table 5 for the lowest speed approved for
the heating output of the unit. Since the blower
leads connect to the control box, blower speed
selection is accomplished through use of the
proper color-coded blower lead located inside
the control box. The speed(s) set by the factory
may be different from that shown on the wiring
diagrams. See the unit control box for blower
speed(s) set at factory.
Blower Installation:
1. Turn off all electrical supply circuits to the
furnace at the main service panel.
2. Remove furnace front door and switch
furnace circuit breaker(s) to “OFF”.
3. Disconnect the motor plug from the control
panel receptacle.
4. Remove one screw from left side of blower
and three screws from right side of blower;
slide blower forward and remove.

IMPORTANT:
a. Remove heating and cooling leads from
motor terminals 1-5.
b. Choose desired speeds and seat terminal
back into motor terminals 1-5.
If a relay box is installed, blower
speedsforheatingandcoolingareset
inside the relay box (see instructions
included with relay box). The blower
speed inside the furnace control box
must be set to low or medium-low.
Neverchangetoaheatingspeedlower
than that shown in Table 5.
Same Speed, Heating and A/C: Use loose
white jumper wire supplied with unit and jumper
between terminals 5 & 2 on blower relay. On
E3EX, remove one wire from motor terminals
1-5, while leaving one wire on the required
blower speed.
Changing Blower Speed
E3EH: The selected heating blower lead is at-
tached to the wire lead attached to terminal 2
of the blower selector switch.
a. Remove blower lead from the wire lead off
of terminal 2.
b. Choose desired speed.
c. Attach new blower lead to wire lead off
terminal 2 of blower selector switch.
See Table 6 for blower performance data.
Installing Control Circuit Wiring
NOTE: Installation of a five-wire thermostat
circuit is recommended to provide for future
addition of a heat/cool thermostat.
1. Install the 24V control-circuit cable through
plastic bushing at either side of furnace.
a. For models without a relay box, connect
wires to furnace at blower plug pigtails (see
wiring diagrams). Secure all connections
with wire nuts.
E2EB: The selected heating blower lead is at-
tachedtoterminal6onblowerrelay.Theselected
cooling blower lead is attached to terminal 4 on
blower relay.
b. For units with a relay box installed, make
wiring connections at relay box low-voltage
terminal board. (See relay box installation
instructions.)
2. Route control circuit wiring to wall
thermostat and outdoor section, if installed.
(See relay box installation instructions if
applicable.)
a. Remove heating blower lead from terminal
6 on blower relay.
b. Choose desired speed and install new
blower lead onto terminal 6 of blower relay
for new heating speed.
c. Remove cooling blower lead from terminal
4 on blower relay.
d. Install new blower lead onto terminal 4 of
blower relay for new cooling speed.
3. Set anticipator per Table 7 or per the mark-
ing on the unit.
4. See Figure 31 (non-Platinum) and Figure
32 (Platinum) for E3EB thermostat connec-
tions.

CAUTION: When sizing the wire, you must follow the guidelines of the
latest revision of the NEC. NM-B wire is equivalent to “Romex” cable. SEU
is equivalent to service entry cable. For NEC type NM-B wire, you must
size the wire using 60C ratings per NEC article 326.
* MinimumovercurrentprotectionperNEC424-3bnottobelessthan125%
