Gas Furnace Standing Pilot

The standing pilot flame is oftentimes referred to as the pilot light of a gas furnace.

Gas furnace standing pilot.

If your pilot light goes out all you need to. A standing pilot gas furnace uses a small continuously burning flame as a source of ignition for the main gas burner. Sometimes it is referred to as a safety pilot. Older style furnaces with an afue of 80 normally have a standing pilot flame meaning the flame is lit at all times.

Furnaces with a standing pilot have a combination gas valve and thermocouple for a flame safety control system. A standing pilot gas furnace is equipped with a naturally aspirating gas burner a draft hood a solenoid operated main gas valve a continuously operating pilot light standing pilot a thermocouple safety device a 24 volt ac transformer a heat exchanger a blower and motor assembly and one or more air filters. This flame called a pilot light burns a constant flow of a small amount of. Standing pilot is an older way of igniting a furnace.

A standing pilot gas furnace is a particular type of gas furnace. It requires a pilot light to be lit 24 7. A standing pilot light is actually fairly simple in design. Most modern gas furnaces have a burner that is ignited by an electronic ignition.

When the pilot light is lit the thermocouple registers the heat and generates an electric current. A bit of composite metal wire called a thermocouple connects the burner to a valve in the gas line. In either case the standing pilot gas furnace is quickly becoming a thing of the past and being slowly replaced with newer more efficient electronic ignition furnaces. If the pilot light goes out the furnace or water heater will not work.

A gas line terminates in a small burner which creates the flame. In this episode of repair and replace vance shows how to relight the pilot light in a standing pilot furnace. In such furnaces the standing pilot works together as a team with the thermocouple the electronic device that senses if the pilot flame is hot enough to ignite natural gas or propane fuel to the burner to control gas flow and the ignition of your furnace s burners.
