Adjusting a Furnace Gas Valve for Safety and Efficiency
Adjusting your furnace gas valve can help ensure your home heating system is running safely and efficiently, save you money on your annual energy bills, and give you peace of mind through winter. Here's how to adjust a furnace gas valve:
- Familiarize yourself with the safety guidelines for furnace gas valves. Make sure you know the correct pressure setting and wear protective clothing when you’re adjusting a furnace gas valve.
- Locate the furnace gas valve. These valves are usually near the furnace and typically have a round gauge and scales for turning.
- Turn off the gas. Turn off the main gas line, which is usually located near the furnace, and make sure there is no pilot light lit on the furnace.
- Check the pressure. Make sure the pressure gauge is at the right setting. If not, turn the adjust knob to adjust the pressure.
- Test the pressure by turning the level up to a snug but not tight setting. If the pressure is too high or too low, you may need to adjust the settings on the knob.
- Restart the furnace. Turn the main gas line back on and light a pilot light. Re-test the pressure and make sure the readings stay at the recommended level.
- Turn off the pilot light when finished. Don’t forget to turn off the main gas line when you are done.
Following these steps will help keep your furnace running safely and efficiently throughout the winter months. Remember to keep an eye on the pressure gauge so you can adjust the settings when needed.
