Operating Instructions

Once installed by a qualified professional, operating your Goodman furnace is typically managed through your home's thermostat. Ensure the thermostat is correctly programmed for your desired heating schedule and temperature settings.

Starting the Furnace

1. Ensure the gas supply valve to the furnace is open.
2. Verify the electrical power switch for the furnace is in the "ON" position.
3. Set your thermostat to "HEAT" mode.
4. Adjust the thermostat's temperature setting to a level higher than the current room temperature. The furnace should initiate its heating cycle.
5. Listen for the igniter to glow, followed by the sound of the burners igniting. The blower fan will typically start after a short delay once the heat exchanger warms up.

Stopping the Furnace

• To temporarily stop heating, set your thermostat to "OFF" or lower the temperature setting below the current room temperature.
• For extended periods of absence or maintenance, turn off the electrical power switch to the furnace and close the manual gas shut-off valve.

If the furnace fails to ignite or operate correctly, refer to the Troubleshooting section or contact a qualified service technician.

Maintenance

Regular maintenance is crucial for the efficient and safe operation of your furnace. Some tasks can be performed by the homeowner, while others require a qualified HVAC technician.

Homeowner Maintenance (Monthly/Quarterly)

• Air Filter Replacement/Cleaning: Check your furnace filter monthly, especially during periods of heavy use. Replace disposable filters or clean reusable filters as needed (typically every 1-3 months) to ensure proper airflow and efficiency.
• Clear Area Around Furnace: Ensure the area around the furnace is free from obstructions, combustible materials, and debris to allow for proper airflow and safe operation.
• Check Condensate Drain: Periodically check the condensate drain line for clogs or blockages. Clear any visible debris.

Professional Maintenance (Annually)

It is highly recommended to have your furnace inspected and serviced by a qualified HVAC technician at least once a year, preferably before the heating season begins. Professional maintenance includes:

• Cleaning and inspection of burners and heat exchanger.
• Checking gas pressure and connections.
• Lubricating moving parts (if applicable).
• Testing safety controls and electrical components.
• Inspecting flue pipe and venting system.
