ETTING THE EAT NTICIPATOR
The heat anticipator in older, non electronic room thermostats
must be adjusted correctly to obtain the proper number of cycles
per hour and to prevent "overshooting" the setting. Set the heat
anticipator setting to 0.7 amps. Follow the thermostat
manufacturer's instructions on how to adjust the heat anticipa-
tor.

WIRING
The furnace integrated control module is equipped with line volt-
age 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 accessories.
Follow the air cleaner manufacturers' instructions for locating,
mounting, grounding, and controlling these accessories. Acces-
sory wiring connections are to be made through the 1/4" quick
connect terminals provided on the furnace integrated 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 illustration.

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 electronic air cleaner terminals
(EAC) are energized with 115 volts whenever the circulator blower
is energized.
24 V H
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 connect a
field supplied jumper wire with a "piggyback" terminal to the
pressure switch terminal. Reconnect the yellow wire to the "piggy-
back" 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 C terminal on
the furnace control board (or to the COM side of the 24 VAC trans-
former). DO NOT CONNECT 115V HUMIDIFIER TO THESE TERMI-
NALS.

AS UPPLY AND IPING
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 re-
quired 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 main-
tained 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.
