Gas Valve

What is a gas valve?

A gas valve is a component of a gas furnace which regulates the flow of gas to the burner. It opens up sending gas to ignite the burner when the thermostat signals for heat.

Where is it located?

It is located outside near the gas pipe coming up from the ground by the gas meter. It requires a wrench to open or close.

Maintenance Tips

  • Inspect for any rust or debris every 3 months
  • Check that the valve is receiving 24V at ignition annually
  • Check that the pressure is correct and the valve is able to open annually
  • Inspect the wiring annually

    • Lifespan

    The lifespan of a gas valve is 10 - 20 years.
