1. Turn off power to furnace at circuit breaker.
2. Remove thermostat cover and connect wires: R (24V), W (Heat), G (Fan), C (Common).
3. For AC compatibility: Connect Y (Cooling) terminal.
4. Secure connections and replace cover.
5. Restore power and test operation.

Tip: Use color-coded thermostat wire for easy identification. Follow thermostat manufacturer instructions.

Operation

Normal heating cycle operation and seasonal use.

1. Set thermostat to HEAT mode and desired temperature.
2. Furnace initiates: Inducer motor starts, pressure switch verifies, igniter heats.
3. Gas valve opens: Main burners ignite, heat exchanger warms.
4. Blower activates: Circulates warm air through ductwork.
5. Cycle completes: Thermostat satisfied, gas valve closes, blower continues briefly.
6. Seasonal shutdown: Turn gas valve to OFF position during off-season.

WARNING! Never operate furnace without proper venting and combustion air. Monitor for unusual noises or odors.

Maintenance

Regular maintenance ensures optimal performance and safety.

1. Monthly: Check and replace air filter as needed.
2. Seasonal: Inspect burners and heat exchanger for corrosion.
3. Annual: Professional inspection and cleaning recommended.
4. Check vent system: Ensure no obstructions in intake/exhaust.
5. Test safety controls: Verify proper operation of limit switches.

Care & Cleaning

Turn off power and gas supply before cleaning. Use soft brush and vacuum for dust removal.

CAUTION! Never use water or liquid cleaners on electrical components. Keep combustion area clear of debris.
