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) connection
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.

IMPORTANT NOTE
As a two-stage non-communicating furnace, the furnace integrated
control module provides terminals for both “W1” and “W2”, and
“Y1” and “Y2” thermostat connections.  This allows the furnace to
support the following system applications:  ‘Two-Stage Heating
Only’, ‘Two-Stage Heating with Single Stage Cooling’, and ‘Two-
Stage Heating with Two-Stage Cooling’.  Refer to the following fig-
ures for proper connections to the integrated control module.
Low voltage connections can be made through either the right or
left side panel. Thermostat wiring entrance holes are located in the
blower compartment.  The following figure shows connections for a
“heat/cool system”.
This furnace is equipped with a 40 VA transformer to facilitate use
with most cooling equipment.  Consult the wiring diagram, located
on the blower compartment door, for further details of 115 Volt and
24 Volt wiring.
NOTE: Use of ramping profiles requires a jumper between Y1
and O.

Low Voltage Connections with Auxiliary Terminals
The auxiliary contacts are shipped with a factory installed
jumper. As an option, the auxiliary contacts may be wired to
a normally closed float switch.  In the event of open contacts,
the furnace will be disabled until the condition is corrected.
These are 24 volt terminals fed internally, do not apply another
voltage source to these terminals.
