Why does my gas fireplace go out after a few minutes?
If you get dust in the pilot assembly and the pilot needs to be cleaned out, it produces a “lazy” flame, which will be disturbed by the draught of the main burners. The flame lifts away from the thermocouple and causes the temperature on the tip of the thermocouple to drop. This, in turn, makes the gas valve shut off.
Why does the pilot light on my gas fireplace keep going out?
If the pilot light on your gas fireplace won’t stay lit, a very likely culprit is a component called a thermocouple. A thermocouple is a safety device and is a component of the ignition system. Its purpose is to not allow the gas valve to open if the pilot light isn’t lit.
Why does my fire keep going out?
The ‘Fire Triangle’ taught us that fire needs three things to burn: oxygen, heat and fuel. … While the most common causes of log burners going out are insufficient oxygen, fuel or heat, stoves also rely on a properly functioning chimney. The purpose of this is to draw out exhaust fumes that could suffocate your fire.
How do I stop my pilot light from blowing out?
You should hold down on the pilot light for at least five seconds once it is lit before letting go. This will ensure your pilot light won’t blow out right after you light it.
How do you know if you have a bad thermocouple?
If you can’t get the flame to light at all, and you’re sure the gas is on, there’s probably an obstruction in the pilot tube. If the flame lights and goes out when you release the gas control knob after holding it in for the recommended 20 to 30 seconds, that’s the sign of a thermocouple malfunction.
Why does my propane fire pit not stay lit?
When the pilot won’t light, you can often trace the problem to a lack of propane, either because the tank is empty or a valve is closed. If the pilot won’t stay lit, the problem is usually related to the thermocouple, a heat-sensitive electrode that signals the gas valve to stay open when the pilot is on.
Do gas fireplaces shut off automatically?
Nearly every new gas fireplace comes equipped with safety features such as a 100% fail-safe shut-off valve. If the pilot flame goes out, the gas flow will automatically turn off. … This device automatically shuts the gas off if the temperature in the fireplace gets too cold or if too much carbon monoxide builds up.
What causes a fireplace not to draw?
The main reasons why your wood stove does not draw can include: The stove or flue is too cold. The flue or chimney is dirty. The room or house is too airtight.

How do you test a gas fireplace valve?
A digital multimeter can be used to check the voltage in the presence of a pilot flame as well as test for a drop in potential when the main valve is activated. This can be done by locating the red and white wires connected to the TP/TH and TP terminals on the main control valve.
Does cleaning a thermocouple help?
Yes, you can clean a thermocouple, but the task must be done with a light touch. Remove the thermocouple from the process assembly, using a steel wool or emery cloth, lightly clean the tip removing any build up. Cleaning a thermocouple is not a fix for an issue, such as inaccurate readings.

What does a thermocouple do in a gas fire pit?
Thermocouple. Some fire pits have a thermocouple which senses the heat from the pilot light flame. That signals the gas valve to stay open when the pilot is on.

What is the 2 10 rule?
If you are farther than 10′ away from the peak, your chimney needs to be 2′ above the highest point within 10′. For example, your chimney is exiting 20′ away from the peak and you have a 6/12 pitch roof.
Why does my fire keep going out Valheim?

Why do my logs burn black?
Perhaps the main cause of blackening of stove glass is the burning of unseasoned wood. All logs should be seasoned – that is cut, chopped and left to air – for at least 12 months to allow the moisture level to drop to around 20-25%. … This causes an incomplete burn and results in excessive smoke being produced.
What is a fireplace damper?
A chimney damper prevents conditioned (warmed or cooled) house air from escaping through the flue when you’re not using the fireplace. You need to open the damper when you start a fire to allow for proper airflow and let the smoke out.
Can I replace a thermocouple myself?
The No. 1 cause of pilot lights that won’t stay lit is a worn-out thermocouple. It’s easy to replace and a new one costs $5 to $10. Rather than trying to unfasten the thermocouple inside the water heater’s burning chamber, it’s easier to remove the whole burner and thermocouple assembly.
What's a thermocouple look like?
The thermocouple looks like a piece of metal tubing smaller than a soda straw. To find it, first locate the gas control box. This is the box that the main gas line enters, where you turn the gas on in the furnace. (On most furnaces, it also houses the button that you hold open or push to relight the pilot.)
How long do thermocouples last?
How to Tell if You Have a Bad Thermocouple? Thermocouples can last up to 10 years if properly installed and maintained, while furnaces can last 15-20 years, although either may wear out sooner in multifamily units.

What causes a thermocouple to fail?
METAL FATIGUE Changes in temperature can cause regular expansion and contraction in metal, which will cause thermocouples to weaken over time. After enough time, metal fatigue can cause a thermocouple to break. … If thermocouples start to give out unusual readings, it may be suffering from metal fatigue.
What do thermocouples do?
A thermocouple is a sensor that measures temperature. It consists of two different types of metals, joined together at one end. When the junction of the two metals is heated or cooled, a voltage is created that can be correlated back to the temperature.
