Installation

Unpack and inspect contents. Ensure proper location with adequate clearance.

  1. Position furnace: Place on stable, level surface with proper clearances.
  2. Connect gas line: Use approved gas piping and fittings; pressure test required.
  3. Connect electrical: 120V AC power supply with proper grounding.
  4. Connect venting: Install PVC flue pipes according to local codes.
  5. Connect thermostat: Low-voltage wiring to control board.
  6. Install filter: Proper size and orientation.

WARNING! Installation must be performed by qualified HVAC technician. Gas leaks can cause explosion or fire.

First-Time Setup

Power on furnace; follow startup procedure.

  1. Verify gas supply: Ensure gas valve is open and pressure is correct.
  2. Check electrical: Confirm proper voltage at unit.
  3. Set thermostat: Program desired temperature settings.
  4. Test operation: Initiate heating cycle and monitor performance.
  5. Check airflow: Verify proper airflow through registers.
  6. Inspect venting: Confirm proper draft and exhaust.

CAUTION! Carbon monoxide hazard - ensure proper venting before operation.

Specifications

Controls and Settings

Access control board via front panel. Diagnostic LED for error codes.

Thermostat: HEAT/COOL/OFF, FAN AUTO/ON, temperature setting, program schedule.

Control Board: DIP switches for blower speeds, gas heat timing, accessory configuration. Diagnostic codes: LED flash patterns indicate specific faults. Gas valve: Pressure adjustment screws (qualified technician only). Blower: Speed taps for different airflow requirements.

Connecting Thermostat

Standard 5-wire thermostat connection: R, C, W, G, Y terminals.

  1. Turn off power to furnace before wiring.
  2. Connect thermostat wires to control board terminals.
  3. Match wire colors to terminal labels.
  4. Secure connections and replace access panel.
  5. Restore power and test operation.

Tip: Use compatible thermostat for full functionality.

Operation

Normal heating cycle operation.

  1. Thermostat calls for heat: Sends signal to control board.
  2. Inducer motor starts: Creates draft through heat exchanger.
  3. Pressure switch verifies: Confirms proper draft.
  4. Hot surface igniter glows: Heats up for ignition.
  5. Gas valve opens: Fuel flows to burners.
  6. Ignition occurs: Burners light and heat exchanger warms.
  7. Blower starts: Circulates warm air through ducts.
  8. Cycle completes: Thermostat satisfied, system shuts down.

WARNING! Never block air vents or returns. Maintain clear combustion air supply.

Maintenance

Regular maintenance ensures optimal performance and safety.

  1. Monthly: Check and replace air filter as needed.
  2. Seasonal: Inspect vent pipes for obstructions.
  3. Annual: Professional inspection and cleaning.
  4. Check burners: Clean if necessary.
  5. Inspect heat exchanger: For cracks or damage.
  6. Lubricate blower motor: If required.

Care & Cleaning

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

CAUTION! Do not use water or liquid cleaners. Keep electrical components dry.
