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-

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.

DOWNFLOW SYSTEMS OR  
PLATINUM SYSTEM  
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

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.

always use method A.  
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  
using Method B.On narrow ducts, there may be  
insufficient clearance to bend the tabs on two  
sides of the finger tab duct connector. In such  
Method A - Platinum Series  
NOTE: Flex duct used must have a minimum  
temperature rating of 200° F and meet all  
other applicable codes and standards.  
1. Place duct connector through opening in  
floor. See Figure 9.  
2. Connect 14” supply duct.

breakers (Figures 20 and 21).  
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).

each supply circuit used.  
5. Installnewblowerensuringthesideanges  
engage under side mounting tabs (three on  
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

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.

is equivalent to service entry cable. For NEC type NM-B wire, you must  
size the wire using 60C ratings per NEC article 326.
