Installation

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

1. Position furnace: Place on stable, level surface with proper clearances (refer to specifications).
2. Connect gas supply: Use black iron pipe with proper thread sealant; pressure test for leaks.
3. Connect electrical: 120V AC power supply with proper grounding; connect thermostat wires.
4. Install venting: Use approved vent pipe materials; maintain proper slope and clearances.
5. Connect ductwork: Secure supply and return air ducts; ensure proper airflow.

WARNING! Gas furnace installation must be performed by qualified technician. Improper installation can cause fire, explosion, or carbon monoxide poisoning.

First-Time Setup

After installation, perform initial startup procedure.

1. Verify installations: Check all connections (gas, electrical, venting, ductwork).
2. Install air filter: Insert clean 1-inch filter in filter compartment.
3. Power on: Turn on electrical power and gas supply.
4. Test operation: Set thermostat to heat mode above room temperature.
5. Check airflow: Verify proper airflow from all supply registers.
6. Monitor operation: Observe complete heating cycle for proper operation.

CAUTION! Never operate furnace without proper venting and air filter installed.

2. Remove thermostat cover and label existing wires.
3. Connect wires: R (power), W (heat), G (fan), C (common).
4. Secure thermostat base to wall and replace cover.
5. Restore power and test operation.

Tip: Use compatible thermostat for optimal performance and efficiency.

Operating Your Furnace

Normal heating operation controlled by thermostat.

1. Set thermostat to desired temperature in HEAT mode.
2. Furnace will initiate heating cycle when room temperature drops below set point.
3. Ignition sequence: Blower purges, igniter heats, gas valve opens, burners light.
4. Heating cycle: Burners heat heat exchanger, blower circulates warm air.
5. Shutdown: Thermostat satisfied, gas valve closes, blower continues for post-purge.
6. Fan Operation: AUTO (cycles with heat) or ON (continuous circulation).

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

Maintenance Features

Regular maintenance ensures efficient and safe operation.

Air Filter: Replace every 1-3 months during heating season. Burner Inspection: Annual cleaning by qualified technician. Blower Maintenance: Annual cleaning and lubrication. Safety System: Monthly test of carbon monoxide detectors.

Care & Cleaning

Turn off power before any cleaning. Keep area around furnace clear and clean.

Filter Replacement: Slide out old filter, insert new one with arrow pointing toward blower. External Cleaning: Wipe exterior with damp cloth. Vent Clearance: Keep vent terminal clear of snow, debris, and vegetation.

CAUTION! Do not attempt to clean burners or heat exchanger - qualified technician only.
