In a pilot light, one of the junctions of a thermocouple is sitting in the pilot light’s flame. The electricity that is created runs to a small electromagnetic valve and holds it open. If the pilot light blows out, the thermocouple quickly cools off. It stops generating electricity and the valve closes.
How do you relight an automatic pilot light?
Press the gas control knob down all the way and hold it in the depressed position. If you have no igniter, move the match or barbecue lighter flame to the end of the pilot tube; the pilot flame should light immediately. If you have a spark igniter, press the ignition button until the pilot flame ignites.
Is there a pilot light with electronic ignition?
An electronic ignition is a device that replaces conventional pilot lights in almost all newly-manufactured furnaces. Like a conventional pilot light, an intermittent pilot light still uses a small, gas-powered flame to ignite the furnace’s burners.
How do you light a gas heater with electronic pilot?
If you have a gas furnace, here are the steps on how to light a pilot light.
- First, locate the pilot valve on the furnace.
- Find the gas valve and turn it to the “off” position.
- Turn the valve to the “pilot” position.
- Press and hold the reset button.
- If the reset button fails, ignite the lighter.
Do you need electricity to light a pilot light?
It requires an electric source to create a spark that ignites the pilot light. If the power is out, the fireplace will not ignite. However, most gas fireplaces use a battery back-up for an IPI ignition system.
How do you reignite a pilot light?
Relight the pilot light. Turn the knob to “Pilot,” and let gas to flow to the pilot. Light a lighter or match, then push in the reset button. Hold your flame to the pilot light’s opening. Keep the reset switch depressed until the pilot light is burning steadily.
Why did my pilot light go out?
Some of the possible serious reasons for pilot lights to go out include loose or broken gas valves, thermocouples or heat exchangers, faulty venting, low gas pressure, or high winds. If you believe there is a serious problem, don’t hesitate to contact a professional.
Can you manually light a gas furnace with electronic ignition?
If your furnace is equipped with an electronic igniter, you cannot light the furnace manually. However, you may be able to get the furnace working by turning off the igniter and resetting it. Find the paperwork for your particular furnace to locate the reset button or switch.
How do electronic ignition systems work?
An electronic ignition system is a type of ignition system that works electronic circuits, usually by transistors. The transistors are controlled by sensors to generate electric pulses which then generate a high voltage spark that can burn the lean mixture and provide a better economy and lower emission.
How does an electronic ignition water heater work?
An electronic gas ignition system utilizes solid-state controls for igniting the flame and proving the flame. Electronic ignition gas systems do not use a thermocouple or thermopile to prove the flame. Electronic ignition gas ignition systems use a flame sensor that measures microamps to prove the flame.
Does gas still flow when pilot light goes out?
If your pilot light repeatedly goes out, this is a likely culprit. If this flame sensor should fail, gas will continue to flow even after the pilot light has been extinguished, causing a safety hazard, and requiring immediate repair.
Should the pilot light always be on in a gas heater?
Should the pilot light always be on in a gas fireplace? Most gas fireplaces rely on a “continuous pilot light,” a type of pilot that remains lit so long as gas is flowing to the unit. If you have a continuous pilot light system, you should always see a pilot flame unless you have manually turned the system off.
Why is my gas heater not lighting?
The pilot light or ignition sensor is usually the most common issue when your furnace will not ignite. Then, remove the front panel to find the ignitor or ignition sensor. This is typically located near the burners. If the sensor or ignitor is dirty, it will need to be cleaned.
Can a pilot light cause a fire?
When the appliance is turned on, a valve releases more gas, which is ignited by the pilot light. If this leak continues, its concentration may reach a point where a spark – such as that from a cigarette lighter, static electricity, or even the pilot light itself as it is re-lit – will cause a fire or even an explosion.
Are pilot lights always on?
The pilot light can be a “steady-on” pilot, or an ‘intermittent” or an electronic ignition system. The later type of pilot light is only on when the valve is open and the fireplace is operating. A millivolt valve utilizes a pilot light that is always lit.
How much gas does a pilot light use?
How much gas does a pilot light require? Most pilot lights consume around 600 BTUs of gas every hour. If you leave your pilot light on for an entire day, it would roughly consume 14,400 BTU’s every day.
