Features at a Glance

Key components: Stainless steel heat exchanger, variable-speed ECM blower motor, electronic ignition system, pressure switches, flame sensor, gas valve, and diagnostic control board.

Installation Requirements

Professional installation required. Verify local codes and obtain permits.

1. Location: Install in dry, clean area with proper clearances and combustion air.
2. Venting: Use approved PVC or ABS materials for high-efficiency venting system.
3. Gas Supply: Connect to proper gas type with approved piping and shutoff valve.
4. Electrical: Connect to 120V AC power with proper grounding and disconnect.
5. Drainage: Install condensate drain line with proper slope and trap.
6. Thermostat: Connect compatible 24V thermostat with appropriate wiring.

WARNING! Gas furnaces produce carbon monoxide; proper venting is critical. Only qualified technicians should perform installation.

First-Time Setup

After installation, perform initial startup and system check.

1. Verify all connections: Gas, electrical, venting, and drain lines secure.
2. Check gas pressure: Adjust manifold pressure per specifications.
3. Test safety controls: Verify limit switches, pressure switches, and flame sensor operation.
4. Program thermostat: Set heating schedule and temperature preferences.
5. Run system: Start furnace and check for proper ignition and operation.
6. Monitor operation: Verify correct airflow and temperature rise.

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

Gas Valve: Pressure adjustment screws (professional service only). Limit Controls: Manual reset high-limit switch for overheating protection.

Operating Instructions

Normal operation controlled by thermostat. System cycles automatically.

1. Set thermostat to desired temperature and HEAT mode.
2. Furnace initiates startup sequence: inducer motor, pressure switch check, ignition, gas valve opening.
3. Burners ignite; flame sensor confirms operation; blower starts after heat exchanger warms.
4. System runs until thermostat satisfied, then shuts down in reverse sequence.
5. Continuous fan mode available for constant air circulation.

Tip: Keep thermostat away from heat sources and drafts for accurate temperature control.

Maintenance Procedures

Annual professional maintenance recommended for optimal performance.

1. Monthly: Check and replace air filter as needed.
2. Seasonal: Inspect vent pipes for obstructions or damage.
3. Annual: Professional cleaning of burners, heat exchanger, and blower assembly.
4. Annual: Check gas pressure, electrical connections, and safety controls.
5. Annual: Lubricate motor bearings if required (most ECM motors are sealed).
6. Annual: Test and calibrate thermostat operation.

WARNING! Turn off power and gas supply before performing any maintenance. Only qualified technicians should service gas components.

Safety Features

Multiple safety systems protect against hazardous conditions.

Care & Cleaning

Regular cleaning maintains efficiency and extends equipment life.

1. Air Filter: Replace every 1-3 months depending on usage and environment.
2. Vent Pipes: Keep clear of debris, snow, ice, or insect nests.
3. Burners: Professional cleaning to remove dust and corrosion.
4. Blower: Vacuum dust and debris from wheel and housing.
5. Drain System: Flush condensate lines to prevent clogs.

CAUTION! Never use water or cleaning chemicals on electrical components. Keep combustion area clear of flammable materials.
