WARNING
To avoid the risk of electrical shock, injury,
or death, the furnace must be electrically
grounded in accordance with local codes
or, in their absence, with the latest edition
of The National Electric Code.
To ensure proper unit grounding, the ground wire should
run from the furnace ground screw located inside the
furnace junction box all the way back to the electrical panel.
NOTE: Do not use gas piping as an electrical ground. To
confirm proper unit grounding, turn off the electrical power
and perform the following check.
1. Measure resistance between the neutral (white) con-
nection and one of the burners.
2. Resistance should measure 10 ohms or less.
This furnace is equipped with a blower door interlock switch
which interrupts unit voltage when the blower door is
opened for servicing. Do not defeat this switch.

24 VOLT THERMOSTAT WIRING

NOTE: Wire routing must not interfere with circulator blower
operation, filter removal, or routine maintenance.
Low voltage connections can be made through either the
right or left side panel. Thermostat wiring entrance holes
are located adjacent to the junction box locations in the
blower compartment. Wire routing must not to interfere
with circulator blower operation, filter removal, or routine
maintenance. Refer to the following figure for thermostat
connections to the integrated control module terminal strip.

WARNING
To avoid electrical shock, injury or death,
disconnect electrical power before
servicing, or changing any electrical wiring.
The furnace's integrated control module is equipped with
line voltage 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 acces-
sories. Follow the humidifier or air cleaner manufacturers'
instructions for locating, mounting, grounding, and control-
ling 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 and neutral termi-
nals are identified as HUM and EAC. All field wiring must
conform to applicable codes. Connections should be made
as shown below.

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 tempera-
ture 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 energized with 115 volts whenever the induced draft
blower is energized. The integrated control module elec-
tronic air cleaner terminals (EAC) are energized with 115
volts whenever the circulator blower is energized.
