SECTION 2.
INSTALLER INFORMATION
GENERAL
These instructions and specifications are primarily intended to assist qualified individuals
experienced in the proper installation of home
heating and air conditioning appliances. Some
local codes require licensed personnel for the
installation and service of this type of equipment. Approved installation, operation, and
maintenance of this central heating system
appliance must be in accordance with the listed
specifications contained in these instructions
and other documents supplied with the furnace
and/or optional air conditioning equipment. Refer
to local authorities having jurisdiction for further
information.
Before beginning installation, read these instructions thoroughly. Follow all warnings and
cautions in the instructions and on the unit.
Improper installation, service adjustment, or
maintenance can cause explosion, fire, electrical shock or other conditions which may result in
personal injury or property damage. Unless
otherwise noted in these instructions, use only
factory-authorized kits and accessories when
modifying this product.
OPTIONAL AIR CONDITIONER
AND HEAT PUMP
Your E2 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.

Overview of E2 Furnace
E2E(-) Series electric furnaces are available in
two models. E2EH models are equipped with
the standard two-speed blower. E2EH models
can be easily converted for use with NORDYNE
split-system air conditioners and heat pumps.
E2EB models are air-conditioning ready; that is,
they are equipped with a multi-speed (fourspeed) blower, blower relay, and cabinet insulation kit. See Table 3 for cooling and heat pump
availability with factory installed blower.
For typical non-ducted return air downflow
applications, an air-conditioner or heat-pump
coil can be installed by mounting the coil directly
on top of the furnace without adding sheet metal
cavities or cutting and trimming wood panels.
A return air grille for closet or alcove installations
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.
Power entrance for all models may be through
the right side or through the bottom of the unit
(when viewing the unit in a downflow position).
UNIT CHECKOUT
Before installing this furnace:
1. Inspect unit for possible shipping damage.
If shipping damage is found, file claim with
transportation company.
2. Record furnace model number and serial
number (see furnace data label) for future
reference.
3. Carefully read all instructions supplied with
optional equipment to be installed with
furnace.

All local codes having jurisdiction shall also
apply.
Air Duct Codes and Specifications
Air ducts must be installed in accordance with
National Fire Protection Association standards
NFPA 90A and NFPA 90B, these instructions,
and all applicable local codes.
• Materials: Air ducts must be aluminum, tin
plate, galvanized sheet steel, or other approved materials for outlet or return air ducts.
• Construction: Snap-Lock or Pittsburgh-Lock
seams are preferred. All other types of
seams must be made tight to prevent leakage.
• Sizing: Supply duct system must be designed
for proper air distribution. Static pressure
measured externally to furnace shall not exceed static pressure rating listed on furnace
nameplate.
• Location of Openings: Duct system must be
designed so that no supply registers are
located in duct system directly below furnace.
Return Air Codes and
Requirements
Non-ducted return air systems may be used for
closet or alcove installations.
NOTE: Applicable installation codes may limit
the furnace to installation in a single-story residence only. Furnace installations other than
closet or alcove installations require ducted
return air systems.
• Wiring materials located in return duct system must conform to NEC Article 300-22(c).
• Gas piping must not run in or through return
air duct system.
• If return air opening is located below top of
furnace, a minimum clearance must be provided between opening and furnace (see
“Accessibility for servicing” in Table 1).
Closed-Off Space Requirements
Living space not served by, and closed off from,
the return air ducts to the furnace by doors,
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.
OPTIONAL EQUIPMENT
Contact your nearest NORDYNE distributor for
a complete list of electric furnace accessories.
Return Air Grille
A return air grille and frame assembly (see
Figure 2) is available for use in non-ducted
return air installations. In downflow alcove installations, the grille and frame assembly may
be mounted directly to the top of the furnace. In
closet installations, a wall mount grille is available for attachment to a door or wall.
Air return to the furnace must have a minimum
free area opening (see Table 1).
Acceptable floor or ceiling return air systems for
closet installations with return air entering
through an opening in the closet floor or ceiling
must meet all of the following requirements:
• Return air opening into closet, regardless of
its location, must not be smaller than size
specified on unit data label.
• If located in floor of closet, return air opening
must be provided with means of preventing
its inadvertent closure by a flat object placed
over opening.
• Materials located in return air duct system
must have a flame-spread classification of
200 or less.
• Noncombustible pans having 1" upturned
flanges must be located beneath openings in
a floor-return duct system.

Optional Automatic Furnace
Damper #901083 -
Furnace may (not required) be equipped with
the optional automatic damper when a packaged air conditioner is installed and connected
to the warm air duct system. This damper prevents cooled air from discharging through the
furnace cabinet, causing excessive cooling of
the immediate area. Refer to instructions supplied with the damper for details.

DOWNFLOW SYSTEMS OR
PLATINUM SYSTEM
The following steps describe installation instructions for an under-the-floor supply duct
system with a return air system that can be
either non-ducted or ducted. Duct connectors
(Table 4) are recommended for this application.
NOTE: Before installing this furnace, consider
all clearances for the installation and future
servicing of the furnace. Refer to Table 1.
Return Air and Filtering Systems
Furnaces may be installed with non-ducted or
ducted return air. For non-ducted return air
systems, either the optional grille and frame
assembly or the optional wall mount grille is
recommended. 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 additional external static pressure produced from the chosen filtering method.
AND DISCARD THIS FILTER.
3. With optional coil housing:
- see coil cabinet instructions for specific
filtering methods.
Filtering Methods - Ducted Return Air
1. Without optional coil housing:
- install a filter with a minimum unrestricted
medium area of 324 square inches in the
duct above the coil that is accessible for
monthly cleaning or replacement by homeowner.
2. With optional coil housing:
-install a filter with a minimum unrestricted
medium area of 324 square inches in the
duct above the coil that is accessible for
monthly cleaning or replacement by homeowner.
Optional Duct Connectors for
Downflow Systems
Duct connectors are recommended for heated
air distribution in under-the-floor duct systems.
With this system, furnaces may be installed on
NOTE: Refer to the instructions supplied with
any additional accessories for further installation details.
Filtering Methods - Non-Ducted Return Air
1. Without A/C or H/P uncased coil:
- use the filter supplied with the furnace;
ensure that the filter is installed mat side
down between the filter retainer and furnace top (see Figure 4).

Selecting Duct Connector
Non Platinum Duct Connector
1. Determine depth of floor cavity from surface of floor to top of supply air duct (see
Figure 5).
2. Select appropriate model from Table 4
which matches X-dimension of floor cavity.
To maximize air delivery, remove reducer
(C in Figure 5) to obtain largest open area
that will fit duct/floor construction.
NOTE: Duct connectors may be
installed in any one of four positions.
