4. Secure the dehumidistat ground wire (typically the green lead)
to the ground screw on the furnace junction box. NOTE:
Ground wire may not be present on all dehumidistats.
5. Turn ON power to furnace.
To enable the dehumidify function on the integrated control module:
1. Cut the jumper wire labeled "CUT FOR DEHUM" located
adjacent to the DEHUM screw terminal.
Once the jumper wire is cut, the dehumidify function is enabled dur-
ing a combination call for cooling (T-Stat) and dehumidification
(Dehum-Stat). The yellow LED adjacent to the DEHUM screw termi-
nal will be illuminated during dehumidification.

OSSIL UEL PPLICATIONS
This furnace can be used in conjunction with a heat pump in a fossil
fuel application. A fossil fuel application refers to a combined gas
furnace and heat pump installation which uses an outdoor tempera-
ture sensor to determine the most cost efficient means of heating
(heat pump, gas furnace, or both).
A heat pump thermostat with three stages of heat is required
to properly use a two-stage furnace in conjunction with a heat
pump. Refer to the fossil fuel kit installation instructions for
additional thermostat requirements.
Strictly follow the wiring guidelines in the fossil fuel kit instal-
lation instructions. All furnace connections must be made to
the furnace two-stage integrated control module and the
"FURNACE" terminal strip on the fossil fuel control board.

O AVOID INJURY, ELECTRICAL SHOCK OR DEATH, DISCONNECT ELECTRICAL
POWER BEFORE SERVICING OR CHANGING ANY ELECTRICAL WIRING.
The furnace's integrated control module is equipped with line volt-
age accessory terminals for controlling power to an optional field-
supplied humidifier and/or electronic air cleaner.
The accessory load specifications are as follows:
Humidifier
Electronic Air Cleaner
Turn OFF power to the furnace before installing any accessories.
Follow the humidifier or air cleaner manufacturers' instructions for
locating, mounting, grounding, and controlling these accessories.
Accessory wiring connections are to be made through the 1/4" quick
connect terminals provided on the furnace integrated control mod-
ule. The humidifier and electronic air cleaner hot and neutral termi-
nals are identified as HUM and EAC. All field wiring must conform to
applicable codes. Connections should be made as shown.

If it is necessary for the installer to supply additional line voltage
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 humidifier terminals (HUM) are ener-
gized with 115 volts whenever the induced draft blower is energized.
The integrated control module electronic air cleaner terminals (EAC)
are energized with 115 volts whenever the circulator blower is ener-
gized.

OLT UMIDIFIER
A 5" long brown wire in the wire harness at the low fire pressure
provides 24 VAC humidifier control. This wire is powered any time
the pressure switch is closed. To connect 24 VAC HUM, connect the
24 VAC line of the humidifier to the 5" brown wire. The connection
can be made by either stripping the wire and using a wire nut or by
using a field supplied quick connect terminal. The wiring must con-
form 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 humidi-
fier to these terminals.

The furnace rating plate includes the approved furnace gas input
rating and gas types. The furnace must be equipped to operate on
the type of gas applied. This includes any conversion kits required
for alternate fuels and/or high altitude.

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 below. The supply pressure must be constant and avail-
able with all other household gas fired appliances operating. The
minimum gas supply pressure must be maintained to prevent unre-
liable ignition. The maximum must not be exceeded to prevent unit
overfiring.
