WARNING

O AVOID THE RISK OF INJURY, ELECTRICAL SHOCK OR DEATH, THE FURNACE

MUST BE ELECTRICALLY GROUNDED IN ACCORDANCE WITH LOCAL CODES OR,

ODE.

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.

NOTE: 

Wire routing must not interfere with circulator blower

operation, filter removal, or routine maintenance.

As a two-stage furnace, the furnace integrated control module pro-
vides terminals for both “W1” and “W2”, and “YLO” and “Y” thermo-
stat connections.  This allows the furnace to support the following
system applications:  ‘Two-Stage Heating Only’, ‘Two-Stage Heat-
ing with Single-Stage Cooling’, and ‘Two-Stage Heating with Two-
Stage Cooling’.  Refer to the following figures and table 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.  Wire routing must not interfere with circulator
blower operation, filter removal, or routine maintenance.

Thermostat Diagrams

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

PPLICATION

A single-stage thermostat with only one heating stage can be used
to control this furnace.  The application of a single-stage thermostat
does not offer “true” thermostat-driven two-stage operation, but pro-
vides a 

timed

 transition from low to high fire.  The furnace will run on

low stage for a fixed period of time before stepping up to high stage
to satisfy the thermostat’s call for heat.  The delay period prior to
stepping up can be set at either 5 or 10 minutes through the DIP
switch adjacent to the Heat Off delay DIP switches on the integrated
control module.  To use a single-stage thermostat, turn off power to
the furnace, move the thermostat selection jumper on the integrated
control module from the “two-stage” position to the “single-stage”
position, turn power back on.  Refer to the following figures.

IRING

The optional usage of a dehumidistat allows the furnace’s circulator
blower to operate at a slightly lower speed during a combined ther-
mostat call for cooling and dehumidistat call for dehumidification.
This lower blower speed enhances dehumidification of the condi-
