| Feature | Description |
|---|---|
| Heat Exchanger | Durable aluminized steel construction for efficient heat transfer |
| Blower Motor | Variable-speed ECM for quiet operation and improved efficiency |
| Ignition System | Electronic hot surface ignitor for reliable startup |
| Vent System | Induced draft motor for proper combustion and venting |
| Control Board | Integrated microprocessor for system monitoring and diagnostics |
| Pressure Switch | Ensures proper venting before ignition |
| Gas Valve | Regulates natural gas flow to burner assembly |
| Filter Rack | Standard 1-inch filter slot for easy maintenance |
| Safety Controls | Includes flame rollout and limit switches |
| Electrical Connection | 120V AC, 60Hz power supply |
Unpack and inspect all components. Ensure proper clearances and venting.
WARNING! Installation must comply with all national and local codes. Gas line connections must be leak-tested. Only qualified HVAC technicians should install this equipment.
After installation, perform initial startup sequence.
CAUTION! Never bypass safety controls. If furnace fails to start properly, shut off power and gas, then diagnose issue.
Integrated control board manages all furnace functions with LED diagnostic light.
Control Board: Monitors safety devices, controls ignition sequence, manages blower speeds, provides diagnostic codes via flashing LED.
Thermostat Connections: Compatible with most 24V thermostats (heat/cool, single-stage). Blower Speeds: Adjustable for heating and cooling modes via motor taps. Limit Switch: Protects against overheating. Flame Sensor: Verifies flame presence during operation. Pressure Switch: Ensures proper vent draft before ignition.
Compatible with single-stage heating/cooling thermostats.
Tip: Use programmable thermostat for optimal efficiency. Ensure thermostat is located away from heat sources and drafts.
Regular maintenance ensures efficiency and longevity.
WARNING! Always turn off electrical power and gas supply before servicing. Only qualified technicians should perform internal maintenance.
Multiple safety systems protect against hazardous conditions.
Flame Rollout Switch: Detects flame outside burner compartment. Limit Switch: Prevents overheating by shutting off gas if temperature exceeds safe level. Pressure Switch: Ensures proper vent draft before allowing ignition. Flame Sensor: Shuts off gas valve if no flame detected during operation. Ignition Lockout: After several failed ignition attempts, system locks out for safety.
Keep furnace area clean and unobstructed.
Exterior: Wipe with dry cloth. Keep combustible materials away. Filter: Replace every 1-3 months depending on usage and environment. Vents: Keep intake and exhaust vents clear of snow, leaves, and debris. Burners: Have professional clean annually to maintain efficiency.
CAUTION! Never use water or cleaning chemicals on furnace components. Do not block combustion air openings.

| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Furnace won't start | Power, thermostat, gas | Check circuit breaker, thermostat setting, gas valve position. |
| Blower runs but no heat | Ignition failure | Check for flashing LED code; verify gas supply; check ignitor. |
| Short cycling | Dirty filter, limit switch | Replace air filter; check for restricted airflow; verify limit operation. |
| Unusual noises | Loose parts, airflow | Tighten access panels; check for duct restrictions; inspect blower wheel. |
| Blower doesn't run | Motor, capacitor, control | Check power to motor; test capacitor; verify control board output. |
| LED flashing code | System fault | Refer to diagnostic chart on furnace or manual for specific code. |
Reset: For lockout conditions, turn thermostat off, then power off furnace for 60 seconds before restarting.
