How to Turn On Your Old Gas Furnace in Your New House

Conquering the task of turning on an old gas furnace in a new house can be a daunting experience, especially if you’re not familiar with the process. However, with the right guidance, you can easily ensure your home stays warm and cozy during the chilly winter months. In this article, we will provide a step-by-step guide on how to turn on your old gas furnace in your new house.

Before You Begin

Before you start, make sure you have the following information and materials ready:

1. Furnace model and serial number: Locate the furnace model and serial number, which is usually found on the rating plate or the furnace’s exterior.
2. Furnace manual: Have a copy of the furnace’s manual, which may be available online or in a book that came with the furnace.
3. Gas shut-off valve: Make sure you know the location of the gas shut-off valve, which is usually situated near the furnace.
4. Wrench or pliers: You may need a wrench or pliers to adjust the gas shut-off valve.

Step-by-Step Instructions

Step 1: Turn Off the Gas Supply

1. Locate the gas shut-off valve, and turn it clockwise to the right (or as directed in the furnace manual) to shut off the gas supply to the furnace. This is an essential safety precaution to avoid a potential gas leak.

Step 2: Clean the Furnace Filter

1. Locate the air filter, usually situated in the return air duct or near the furnace. Remove the filter and clean or replace it, as dirty filters can reduce airflow and efficiency.
2. Replace the filter, ensuring it’s securely installed.

Step 3: Check the Thermostat

1. Make sure the thermostat is set to "heat" mode and the desired temperature. Make sure the battery backup (if applicable) is working correctly.
2. Ensure the thermostat is not stuck in a manual override mode, which may be the case if you’re using an old thermostat.

Step 4: Turn On the Furnace

1. With the gas shut-off valve still turned off, check the furnace’s circuit breaker or fuses. If the breaker is tripped or a fuse is blown, reset or replace it as necessary.
2. Locate the furnace’s ignition switch, usually an electric or gas valve on the side or top of the furnace. Move the switch to the "on" position (as directed in the furnace manual).
3. If your furnace has an electronic ignition, press the "Test" or "ignite" button. If it’s a pilot ignition, light the pilot according to the manufacturer’s instructions.
4. Wait a few minutes for the furnace to heat up, then check the thermostat to ensure the temperature is rising.

Step 5: Test the Furnace

1. Verify that the furnace is producing warm air by checking the thermostats, vents, or radiators.
2. Ensure the furnace sounds normal (e.g., not making strange noises or rattling) and is not producing an unusual smell.

Additional Tips and Reminders

• Always follow the manufacturer’s instructions for the specific furnace and thermostat you’re using.
• Keep in mind that older furnaces may not be as energy-efficient or environmentally friendly as newer models.
• Consider hiring a professional to inspect and maintain your furnace regularly for optimal performance and safety.
• If you experience any issues or concerns, consult your local gas company or a professional HVAC technician for assistance.

By following these steps, you should be able to successfully turn on your old gas furnace in your new house. Remember to stay safe, efficient, and warm during the winter months.
