This is mostly commonly caused by one or more the following reasons: leaky joints in the venting system. excessive horizontal run or number of elbows in the venting system. downdrafts in the exhaust vent.
There are certain situations which result in incomplete combustion and therefore ghosting, including: Artificial logs incorrectly placed in a gas fireplace, causing flames to impinge on a cold surface. Gas pressure that is either too low, too high, or intermittent.
Use an electric meter on volts DC to test if the thermocouple is bad. you can also try to re-light the pilot and see if it goes on. Thermocouples can be cleaned, but this is only a short fix. The pilot will go out again over time. Thermocouples are not expensive. The best thing to do is just change it.
All gas fireplaces are designed with features that make them go out ``on their own''. This is normal. There are limit controls so it doesn't overheat. There are room thermostats so we don't barbeque ourselves or our surroundings. There are also flame proving controls so the gas cannot escape, build up, and explode.
You need to replace the thermocouple and thermopile . Basically the thermocouple senses the flame and keeps the pilot lit and the thermopile produces the voltage to open the gas valve . If the pilot doesn't stay lit it's your thermocouple . You need to replace the thermocouple as cleaning usually doesn't work .
Oxygen depletion alarms are wall mounted near stored gases like nitrogen, helium and argon. If one of the stored gases is released or inadvertently leaks into the air, the oxygen sensor detects the low oxygen level and displays it on the monitor.
Low gas pressure or a faulty gas valve can interrupt the gas supply, causing the fire to burn out. If you can smell gas near the fire, hear hissing sounds, or the gas leak detectors activate, you must contact a professional right away to check for safety.
Fireplace thermocouple replacement costs $150 to $350 total.
Maintain oxygen flow.
If you stack wood too tight, it can snuff out the fire because the air and oxygen doesn't flow between tightly placed wood. You must stack logs somewhat loosely to allow some oxygen flow in between: One or two inches between pieces is typically a good distance.
If the pilot flame ignites but goes out after you release the gas control knob, the cause may be a dirty or defective thermocouple. If the gas is on but the flame will not ignite at all, a pilot tube obstruction is the most likely issue.
Gas Fireplace Igniter Isn't Sparking
If your pilot is lit and the fireplace isn't igniting when you push the button or flip the switch, the igniter may be dirty or defective.
The best way to verify that you need a new thermocouple is to see if your pilot light is lit. If the pilot light can't hold ignition, that means either a problem with the gas supply or, more likely, the need for thermocouple replacement.
RSS. Also often referred to as Gloss or Chemical Ghosting, the term refers to the appearance of a “ghost” image from the reverse side of one printed sheet on the face of the adjacent sheet.
Your gas fireplace could be turning off for several reasons. The most like culprits are likely tied to some kind of problem with your setup. Anything from issues with your pilot light, clogged ports on burners, damage to heating components, and thermocouple/thermopile malfunctions can be to blame.
Here at Boss Plumbing, we highly recommend you not try to replace the thermocouple on your water heater yourself. Though not a highly complex water heater repair, it nevertheless does involve the use of gas. Thus, if you are unsure about what you are doing, one small mistake could lead to a disaster.
The definitive way to identify a bad thermocouple is to test it using a multimeter with alligator clips on the leads. Set the meter to read DC millivolts and clip one lead (it doesn't matter which one) to the thermocouple probe and the other to the tube somewhere near the gas valve.
The thermocouple is a safety device designed to shut off the gas valve if the pilot light goes out. Although, if your thermocouple is old, worn, damaged, wrongly positioned, or malfunctioning, it could have wrongly shut off the gas valve and prevented your pilot light from staying lit.
One of the most common problems faced by homeowners with gas fireplaces is the pilot light going out or not staying lit. The pilot light is a small flame that ignites the gas burner, which produces the heat for your fireplace — if the pilot light goes out, your fireplace won't work.
The typical lifespan of a gas fire
When properly installed and cared for, most gas fires can provide anything from 10 to 15 years of useful life. Some higher-end models or those used infrequently may last 20 years or longer before needing major repairs or replacement.
The cooler air from your living space is drawn into the lower vent of the fireplace. It travels around the firebox, and as it does so, it picks up heat, rises and then exits through a top fireplace vent. In some gas fireplaces, an electric fan helps to circulate the warming air.
Furthermore, space heaters that are not installed properly or those that are damaged or faulty can potentially release CO and other toxic fumes into your room, consume all the oxygen inside that room and result into serious health concerns.
