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 en-
ergized with 115 volts whenever the induced draft blower is ener-
gized. The integrated control module electronic air cleaner termi-
nals (EAC) are energized with 115 volts whenever the circulator
blower is energized.

A 5" long brown wire in the wire harness at the low fire pressure
switch 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 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 transformer). Do not
connect 115V humidifier 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.

OPERATING
Inlet gas supply pressures must be maintained within the ranges
specified in the following table. The supply pressure must be con-
stant and available with all other household gas fired appliances
operating. The minimum gas supply pressure must be maintained
to prevent unreliable ignition. The maximum must not be exceeded
to prevent unit overfiring.

Minimum: 5.0" w.c.
Propane Gas Minimum: 11.0" w.c.
NOTE: NOTE:
NOTE: Adjusting the minimum supply pressure below the limits in NOTE: NOTE:
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 tempera-
ture rise must be within the range listed on the furnace nameplate.
Should this appliance be converted to LP, refer to the instructions
included in the factory authorized LP conversion kit.

altitude. Do not attempt to increase the firing rate by changing
orifices or increasing the manifold pressure. This can cause poor
combustion and equipment failure.
High altitude installations may require both a pressure switch and
an orifice change. These changes are necessary to compensate for
the natural reduction in the density of both the gas fuel and the
combustion air at higher altitude.
For installations above 7000 feet, please refer to your distributor for
required kit(s).
