What is a continuous pilot light?
A standing pilot is the standard ignition device for most natural gas burning heating systems, and has been for many years. It’s a continuously burning flame at the bottom of the heater, responsible for starting the burners that actually generate heat for the home.
What are the two types of pilot lights?
There are two types of electronic ignition, intermittent pilot and hot surface ignition. An intermittent pilot system generates a high voltage electrical spark whenever the thermostat calls for heat. This spark ignites a gas pilot, which then works just like the standing pilot light did.
What is the pilot light called?
Also called pilot, pilot burner. a small flame kept burning continuously, as in a gas stove or furnace, to relight the main gas burners whenever necessary or desired. pilot lamp.
What is a burner pilot?
A pilot light is a small flame that is kept lit in certain gas-fired appliances like your furnace, water heater, and gas fireplace. When you turn on your appliance, gas is released to the main burner and the pilot light ignites that gas to turn on your appliance and provide heat.
How do I know if I have a standing pilot light?
A propane flame should have a bluish-green flame with a tinge of yellow at the tip. To inspect the operation of the standing pilot light: Remove the furnace cover panel, which should expose the burner assembly and pilot. You should be able to see the flame of the pilot light.
What is a 100% shutoff system?
What is a 100% shutoff system? A system is 100% shutoff when there is a failure in the flame-proving device system and both the pilot valve and main gas valve are shut down.
Can you leave gas fireplace on overnight?
No, you should not leave your gas fireplace on overnight as you risk carbon monoxide poisoning. Although it’s never recommended, if your gas fireplace has been properly maintained and designed to run continuously, it may be safe to leave it on.
What does the standing pilot light on a gas burner do?
No matter what you call it, the purpose is to serve as a small ignition flame for the gas burner. When the thermostat signals for gas to be delivered from the gas valve to the burner, the standing pilot ignites the gas flowing to the burners to heat the air in the combustion chamber.
What happens when the pilot light is extinguished on a gas furnace?
If the thermocouple or flame sensor does not sense enough heat from the pilot flame—such as when the pilot is extinguished—then the thermocouple shuts off the gas valve delivering gas to the burners.
What happens when the pilot light goes out?
A photoresistor is used to detect the light from the pilot lamp. When the pilot light goes out, electrical circuitry connected to the photoresistor shuts off the gas valve.
What’s the difference between a pilot light and an automatic pilot?
Unlike older pilot lights, which have to be lighted by hand, automatic pilot lights, now commonly found in most home furnaces, are regulated by a thermostat and only ignite when needed. While older pilots burned constantly, wasting gas, automatic pilot lights come on long enough to ignite the gas supply and then shut off.
Why do pilot lights burn all the time?
You light the gas escaping from the tube, and it burns all the time. You can see, however, that the pilot light creates a potential safety problem. If the pilot light flame were to ever blow out, the gas would keep coming out of the pilot light tube.
What does the pilot light on a gas furnace do?
A gas furnace pilot light is a continuously burning flame. Its main function is to ignite the burners when the furnace is called upon for heat.
How is a pilot light made and how does it work?
How Pilot Lights Work. The way that a pilot light is created is also simple. It is made by allowing a small amount of gas to come from the gas pipe through a small tube. You light the gas escaping from the tube, and it burns all the time. You can see, however, that the pilot light creates a potential safety problem.
What’s the pilot light on a water heater called?
Pilot lights are still common, even though they’re a bit wasteful. If you have an older model furnace or water heater that uses natural gas, or if you have a set of gas logs in your fire place, you have probably seen the small blue flame known as the pilot light.
