WARNING

TO AVOID THE RISK OF INJURY, ELECTRICAL SHOCK 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) 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 servic- ing. Do not defeat this switch.

24 VOLT THERMOSTAT WIRING

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 circula- tor 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 24 Volt wiring.

SINGLE-STAGE THERMOSTAT APPLICATION

A single-stage thermostat with only one heating stage can be used to control this furnace. The application of a single-stage thermo- stat does not offer “true” thermostat-driven two-stage operation, but provides 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 pe- riod prior to stepping up can be set at either 5 or 10 minutes through

24 VOLT DEHUMIDISTAT WIRING

The optional usage of a dehumidistat allows the furnace’s circula- tor blower to operate at a slightly lower speed during a combined thermostat call for cooling and dehumidistat call for dehumidifica-
