WIRING
The furnace integrated control module is equipped with line
voltage accessory terminals for controlling power to an optional
field-supplied electronic air cleaner.
The accessory load specifications are as follows:

Electronic Air Cleaner

Turn OFF power to the furnace before installing any accesso-
ries. Follow the air cleaner manufacturers' instructions for lo-
cating, mounting, grounding, and controlling these accesso-
ries. Accessory wiring connections are to be made through
the 1/4" quick connect terminals provided on the furnace inte-
grated control module. The electronic air cleaner hot terminal
is identified as EAC-H and the neutral terminal is identified as
NEUTRAL. All field wiring must conform to applicable codes.
Connections should be made as shown in the following illustra-
tion.

If it is necessary for the installer to supply additional line volt-
age wiring to the inside of the furnace, the wiring must conform
to all local codes, and have a minimum temperature rating of
105°C. All line voltage wire splices must be made inside the
furnace junction box.
The integrated control module electronic air cleaner terminals
(EAC) are energized with 115 volts whenever the circulator blower
is energized.

AC UMIDIFIER
The yellow wire connected to the I.D. Blower pressure switch
is powered anytime the pressure switch is closed and provides
24 VAC humidifier control. Remove the yellow wire and con-
nect a field supplied jumper wire with a "piggyback" terminal to
the pressure switch terminal. Reconnect the yellow wire to the
"piggyback" terminal on the jumper wire and then connect the
24 VAC line of the humidifier to the stripped end of the jumper
wire. Using a wire nut or a field-supplied quick connect terminal
can make this connection. The wiring must conform to all local
and national codes. Connect the COM side of the humidifier to
the B/C terminal on the furnace control board (or to the COM
side of the 24 VAC transformer). DO NOT CONNECT 115V
HUMIDIFIER TO THESE TERMINALS.

AS UPPLY AND
The furnace rating plate includes the approved furnace gas in-
put rating and gas types. The furnace must be equipped to
operate on the type of gas applied. This includes any conver-
sion kits required for alternate fuels and/or high altitude.
T
O PREVENT UNRELIABLE OPERATION OR EQUIPMENT DAMAGE
INLET GAS SUPPLY PRESSURE MUST BE AS SPECIFIED ON THE UNIT
RATING PLATE WITH ALL OTHER HOUSEHOLD GAS FIRED APPLIANCES
.
OPERATING
Inlet gas supply pressures must be maintained within the ranges
specified in the following table. The supply pressure must be
constant and available with all other household gas fired appli-
ances operating. The minimum gas supply pressure must be
maintained to prevent unreliable ignition. The maximum must
not be exceeded to prevent unit overfiring.
NOTE: Do not remove the gas valve inlet plug before the gas
line is installed. replace if water or debris has been introduced.
INLET GAS SUPPLY PRESSURE
Natural Gas Minimum: 4.5" w.c.
Propane Gas Minimum: 11.0" w.c.
NOTE: Adjusting the minimum supply pressure below the limits
in the above table could lead to unreliable ignition. Gas input to
the burners must not exceed the rated input shown on the
rating plate. Overfiring of the furnace can result in premature
heat exchanger failure. Gas pressures in excess of 13 inches
water column can also cause permanent damage to the gas
valve.
At all altitudes, the manifold pressure must be within 0.3 inches
w.c. of that listed in the Specification Sheet applicable to your
model for the fuel used. At all altitudes and with either fuel, the
air temperature rise must be within the range listed on the fur-
nace nameplate. Should this appliance be converted to LP,
refer to the instructions included in the factory authorized LP
conversion kit.
