WIRING
Furnace wiring is complete except for the power supply and the thermostat wires. See wiring diagrams (Figures 16-21) for wire and fuse size.
See Table 2 for ground wire sizes. Thermostat wires connect through
side of furnace and should also be no smaller than 22 gauge. Power
wires can enter through the side of the unit or through the auxiliary
entrance, located in the bottom of the unit. (See Figure 1). When bringing wiring through the bottom of the furnace, cable connectors must be
installed to hold wiring in place and to relieve any strain on the wiring.
These connectors will also serve as a seal between the furnace and the
floor. Thus, additional sealing is not required.
Refer to the National Electrical Code, Canadian Electrical Code and
local codes for wiring material requirements.
NOTE: The furnaces are equipped with either one or two 60 amp circuit
breakers. These circuit breakers protect the wiring inside of the furnace
in the event of a short circuit. Additionally, these breakers provide a
means of disconnecting the power to the unit. The circuit breakers in
the furnace are not meant to protect the branch circuit wiring between
the furnace and the home's breaker panel. General wire and breaker
sizes are shown in Table 2. If sheathed cable is used, refer to National
Electrical Code, Canadian Electrical Code and local codes for additional requirements concerning supply circuit wiring. Electrical Data can
be found in Table 4.
IMPORTANT: All installation on field wiring must be rated at 60ºC or
higher.
Models for EB23C, EB20C, EB17C and EB15C may be connected to a
single or dual branch circuit.
These units are shipped from the factory set up for dual power supply
connections. For single power supply connections, jumper bars (P/N
3500-378P*) are required and are available from the factory. EB12C is
factory shipped with jumper bars in place. See Figure 12.

THERMOSTAT WIRING SCHEMATIC FOR: BLEND AIR AND FURNACE
The EB*C* Furnaces are A/C ready.
All furnaces installations should include a minimum of four conductor thermostat
wiring to accommodate future air conditioning installations.
Four-conductor wire is required for thermostat connection.
Attach the 4 low voltage wires extending from the control box as follows:
RED RED
WHITE WHITE
GREEN GREEN
BLACK
YELLOW
1. wire from Furnace to thermostat wire.
2. wire from Furnace to thermostat wire.
3. wire from Furnace to thermostat wire.
4. wire from Furnace to condensing unit contactor.
5. Thermostat wire to condensing unit contactor.
For personal safety be sure to turn the electrical power OFF at the
household service box and at the furnace circuit breakers before
attempting any service or maintenance operations. Homeowners
should never perform any maintenance which requires opening
electric box door.
Furnace is equipped with a protective shield over field wiring connection. When field wiring is completed, shield must be replaced to
prevent hazard of electrical shock when using furnace disconnect.
(See Figure 13.)
closely regulate average room air, preferably, where there is air movement back to furnace. Care should be used to locate thermostat away
from hot air discharge openings, lights, etc. Locating height of thermostat is important. Thermostat should be located 52” to 66” (132 - 167.6
cm) above the floor. This is sometimes called the comfort zone.
If a condenser with its own Transformer shares a Heat/Cool Thermostat
with this furnace, use a thermostat with isolating contacts to prevent
interconnection of Class II 24 Volt Systems.
Cycle furnace using the thermostat to make sure it will operate correctly.
Maintenance and operating instructions are in the customer envelope
accompanying the furnace. Give the customer envelope to the home
owner.
When using separate thermostats, a thermostat interlock system
must be provided to prevent simultaneous operation of the furnace
and air conditioner. Simultaneous operation can result in coach
overheating, equipment damage and energy waste. (See Figures
14 and 15.)
Do not connect Yellow wire to thermostat until an outdoor unit is
installed.
FIGURE 13: Field Wiring Shield
SECTION V: THERMOSTAT INSTALLATION
The adjustable heat anticipator in the thermostat is pre-set at 0.4 Amps.
This setting should be checked at the time of installation.
In some cases the thermostat may be a “self-setting" type in which case
no amp setting will be found on the thermostat, eliminating the need for
any field adjustment.
Thermostat should be located on an inside wall in an open area to more

SECTION VI: OPTIONAL AIR
CONDITIONING ACCESSORIES
Failure to install this insulation and coil shelf kit could result in
damage to equipment and/or personal injury. Liability and warranty from the manufacturer could also be void.
This furnace is already equipped with a blower and control system to
add-on air conditioning and heat pump. Insulation and coil shelf kit
(3500-8941* for downflow or 3500-8961* for upflow) must be installed
when adding on such remote air conditioning systems.
HIGH PERFORMANCE BLOWER ACCESSORY PACKAGE
All areas around the line sets, drain hoses and other openings in
the coil shelf should be sealed air tight. Use some moldable compound or caulking to seal the area. Failure to do so may result in
loss of performance and premature compressor failure.
All EB furnaces are equipped with a blower and control system to addon air conditioning and heat pumps to specified sizes. If the requirement is to achieve more air flow or cooling than specified, then the
blower inside the furnace has to be replaced with an accessory blower
package 3500-7901*. This accessory blower package would deliver air
conditioning up to 5-tons, and heat pump up to 4-tons. Accessory package (3500-7901*) includes blower, insulation, coil shelf, trap, clamps,
etc. Please refer to the installation instructions packed with the accessory package for more information.
