Turn OFF power to the furnace before installing any acces-
sories. 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 module. The humidifier and
electronic air cleaner hot terminals are identified as HUM H
and EAC H. The humidifier and electronic air cleaner neutral
terminals are identified as NEUTRAL. 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 terminal (HUM
H) is energized with 115 volts whenever the induced draft
blower is energized. The integrated control module electron -
ic air cleaner terminal (EAC H) is energized with 115 volts
whenever the circulator blower is energized. This terminal
can also be used to provide 115 volt power to a humidifier
transformer. The remaining primary transformer wire would
be connected to the Line N on the control board.

The furnace integrated control module is equipped with
a low voltage terminal for providing power to an optional
field-supplied 24 volt humidifier. The 24V HUM terminal is
energized any time the draft inducer is powered. See con -
nection diagram below.
Note: This is a 24 volt circuit only, the common connection
must be on C terminal of the low voltage terminal strip (where
thermostat wires are connected). Wiring for this circuit must
NOT be connected to the line N location where line voltage
neutral wires are connected.

INLET GAS SUPPLY PRESSURE
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 con -
version kits required for alternate fuels and/or high altitude.
Inlet gas supply pressures must be maintained within the
ranges specified in the adjacent table. The supply pressure
must be constant and available with all other household gas
fired appliances operating. The minimum gas supply pres -
sure must be maintained to prevent unreliable ignition. The
maximum must not be exceeded to prevent unit overfiring.
High Altitude Derate
When this furnace is installed at high altitude, the appropriate
High Altitude orifice kit must be applied. This is required due
to the natural reduction in the density of both the gas fuel
and combustion air as altitude increases. The kit will provide
the proper design certified input rate within the specified
altitude range.
High altitude kits are purchased according to the installation
altitude and usage of either natural or propane gas. Consult
the furnace Specification Sheet for appropriate kits.
