Installation

Unpack and inspect all components. Ensure proper location with adequate clearance.

Position furnace: Place on stable, level surface with proper clearances.
Connect gas supply: Use approved gas piping with shutoff valve.
Connect electrical: 120V AC power supply with proper grounding.
Connect venting: Install approved vent pipe according to local codes.
Connect thermostat: Low-voltage wiring to control board.
Install air 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; verify proper operation sequence.

Check gas connections: Use leak detection solution on all joints.
Verify electrical: Ensure proper voltage and grounding.
Test thermostat: Set to heat mode and verify furnace response.
Check airflow: Verify proper duct connections and filter installation.
Monitor startup: Observe complete heating cycle for normal operation.

CAUTION! Never bypass safety devices. Test carbon monoxide detectors after installation.

Tip: Use compatible thermostat for optimal performance and efficiency.

Operating Procedures

Normal heating cycle operation and seasonal startup.

Set thermostat: Adjust to desired temperature in heat mode.
System startup: Inducer motor runs, pressure switch verifies, igniter heats, gas valve opens.
Flame establishment: Burner ignition, flame sensor confirmation, blower activation.
Normal operation: Continuous heating until thermostat satisfied.
Shutdown: Gas valve closes, blower continues for post-purge.
Seasonal shutdown: Turn off gas and electrical if not used during warm months.

WARNING! Never operate with access panels removed. Keep combustible materials away from furnace.

Safety Features

Flame rollout switches: Shut off gas if flame escapes burner area. High limit switch: Prevents overheating. Pressure switches: Ensure proper venting. Flame sensor: Confirms burner ignition. Gas valve: Automatic shutoff during faults.

Maintenance & Cleaning

Monthly filter inspection/replacement. Annual professional maintenance recommended.

Air filter: Replace every 1-3 months depending on usage.
Burners: Clean annually to remove dust and debris.
Flame sensor: Clean with emery cloth annually.
Blower assembly: Vacuum dust and debris annually.
Vent system: Inspect for obstructions annually.

CAUTION! Always turn off gas and electrical power before servicing. Use only approved replacement parts.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No heat	Thermostat setting, power, gas supply	Check thermostat setting, circuit breaker, gas valve position
Furnace not starting	Safety lockout, pressure switch	Reset power, check venting, verify pressure switch operation
Short cycling	Dirty filter, high limit	Replace filter, check airflow, verify limit switch
Blower not running	Motor, capacitor, control board	Check power to motor, test capacitor, verify control signals
Unusual noises	Loose components, airflow	Tighten access panels, check ductwork, verify blower wheel

Reset: Turn power off for 30 seconds then restore.
