Features at a Glance

Key components: Stainless steel heat exchanger, variable-speed ECM blower motor, hot surface ignition, pressure switches, flame sensor, and integrated control board.

Installation Requirements

Professional installation required. Ensure proper clearances and local code compliance.

1. Location: Install in level, clean, dry area with adequate combustion air.
2. Clearances: Maintain 1-inch clearance from combustible materials.
3. Gas Connection: Use approved gas piping; pressure test before operation.
4. Electrical: 120V AC, 60Hz dedicated circuit required.
5. Venting: Install PVC vent pipes per manufacturer specifications.

WARNING! Gas furnaces produce carbon monoxide; proper venting is critical. Installation must comply with local codes and manufacturer specifications.

First-Time Setup

Initial startup must be performed by qualified technician.

1. Verify all connections: Gas, electrical, and venting properly installed.
2. Check gas pressure: Adjust manifold pressure to specifications.
3. Test safety controls: Verify pressure switches, limit switches operational.
4. Commission system: Run through complete heating cycle.
5. Set blower speeds: Adjust cooling and heating airflow as needed.

CAUTION! Never bypass safety controls. Always test carbon monoxide detectors after installation.

2. Termination: Maintain proper clearances from windows, doors, and air intakes.
3. Ductwork: Size appropriately for CFM requirements; ensure proper sealing.
4. Condensate Drain: Install condensate line with proper trap and drainage.

Tip: Always slope vent pipes back toward furnace for proper condensate drainage.

Operating Instructions

Normal operation controlled by thermostat. System includes automatic safety monitoring.

1. Thermostat Setting: Set thermostat to desired temperature.
2. Startup Sequence: Control board initiates pre-purge, ignition, and flame verification.
3. Normal Operation: Blower starts after heat exchanger warm-up period.
4. Shutdown: Burner shuts off first, followed by blower cool-down period.
5. Error Codes: LED flashes indicate specific fault conditions.

WARNING! If you smell gas, immediately shut off gas supply and call qualified technician.

Maintenance Schedule

Regular maintenance ensures optimal performance and safety.

• Monthly: Check and replace air filter as needed
