Installation Requirements

Unpack and inspect unit for shipping damage. Ensure proper clearances and level mounting surface.

  1. Location: Install in conditioned space (attic, basement, closet, or garage). Maintain clearances per local codes.
  2. Venting: Use approved PVC, CPVC, or ABS pipe for intake and exhaust. Follow manufacturer guidelines for pipe size and length.
  3. Gas Supply: Connect to properly sized gas line with shutoff valve. Use pipe thread sealant approved for natural gas.
  4. Electrical: Connect 115V power supply with dedicated circuit. Connect 24V thermostat wires (R, W, G, Y, C).
  5. Ductwork: Connect supply and return ducts securely. Seal all joints with mastic or UL-181 approved tape.
  6. Condensate Drain: Install trap and route to approved drain. Prime trap if required by local code.

WARNING! Installation must comply with all national and local codes. Only qualified HVAC technicians should install this equipment.

First-Time Startup

Complete installation checks before applying power or gas.

  1. Verify all electrical connections are tight and correct.
  2. Open gas supply valve and check for leaks with soap solution.
  3. Set thermostat to lowest setting and turn on power.
  4. Set thermostat to heat mode and raise temperature above room temp.
  5. Observe ignition sequence: inducer motor starts, pressure switch closes, igniter glows, gas valve opens, flame ignition.
  6. Verify proper flame and check venting operation.
  7. Measure temperature rise across heat exchanger (adjust blower speed if needed).
  8. Set thermostat to desired temperature and test cooling mode if connected to AC.

CAUTION! Never bypass safety devices. If furnace fails to start properly, shut off power and gas, then diagnose per troubleshooting guide.

Specifications

Controls and Settings

Integrated control board manages all furnace operations. Access via front panel cover removal.

Control Board LED: Flashing pattern indicates operating mode or fault code (see troubleshooting).

DIP Switch Settings: Configure blower speeds (HEAT, COOL, FAN), timing delays, and accessory options.

Thermostat Connections: Standard 5-wire terminal (R, W, G, Y, C) for conventional or smart thermostats.

Gas Valve Adjustment: Factory set for natural gas. For LP conversion, replace orifice and adjust regulator.

Blower Speed Taps: Adjust heating and cooling speeds by moving wires to different voltage taps.

Connecting to Ductwork & Thermostat

Proper duct and thermostat connections are critical for performance.

  1. Duct Connection: Seal all joints between furnace and ductwork. Use flexible connectors if needed for vibration isolation.
  2. Return Air: Ensure adequate return air sizing. Filter must be accessible for regular changes.
  3. Thermostat Wiring: Use 18-gauge stranded wire. Connect R (24V), W (Heat), G (Fan), Y (Cool), C (Common).
  4. Zoning Systems: Compatible with most zoning panels. Follow zoning manufacturer's instructions for wiring.
  5. Accessories: Humidifier, electronic air cleaner, or UV light can be added to control board terminals.

Tip: Label all wires during installation for easier future service.

Operating Instructions

Normal operation is controlled by thermostat. Homeowner should only adjust thermostat settings.

  1. Heating Mode: Set thermostat to HEAT and desired temperature. Furnace will cycle automatically.
  2. Fan Operation: Set thermostat to FAN ON for continuous circulation or AUTO for cycle with heating.
  3. System Off: Set thermostat to OFF position to disable heating.
  4. Smart Thermostats: Follow thermostat manufacturer's instructions for programming schedules and settings.
  5. Seasonal Startup: After long inactivity, system may take longer to start as air purges from gas line.

WARNING! Do not attempt to adjust gas valve or control board settings. Contact qualified technician for adjustments.

Maintenance Procedures

Regular maintenance ensures efficiency, safety, and longevity.

  1. Monthly: Check and replace air filter if dirty.
  2. Annual (by technician): Inspect heat exchanger for cracks or corrosion.
  3. Annual: Clean flame sensor with fine sandpaper or steel wool.
  4. Annual: Check and clean burners, pilot assembly (if equipped).
  5. Annual: Inspect vent system for obstructions or damage.
  6. Annual: Check condensate drain line and trap for clogs.
  7. Annual: Verify proper gas pressure and temperature rise.
  8. Annual: Lubricate inducer motor and blower motor if required (most are sealed).

CAUTION! Always turn off electrical power and gas supply before performing any maintenance.

Troubleshooting

SymptomPossible CauseCorrective Action
Furnace won't startPower off, thermostat issue, door switchCheck circuit breaker, thermostat settings, ensure door panels secure
No heat (blower runs)Gas supply, ignition failureCheck gas valve, listen for igniter spark, clean flame sensor
Short cyclingDirty filter, high limit trippedReplace filter, check for restricted airflow, verify temperature rise
Blower won't stopThermostat fan setting, control boardCheck thermostat FAN setting (ON vs AUTO), possible stuck relay
Unusual noisesLoose parts, motor issuesTighten screws, check blower wheel for debris, lubricate if needed
Error code flashingSystem faultCount LED flashes and refer to fault code chart in manual
Pilot outage (if equipped)Draft, thermocoupleCheck venting, clean pilot, replace thermocouple if weak
Condensate leakClogged drain lineClear drain line and trap, ensure proper slope

Reset Procedure: Turn thermostat to OFF, turn off power at furnace for 30 seconds, restore power, set thermostat to heat.
