A clogged or faulty burner can cause performance issues resulting in a low gas flame. In addition, carbon build-up, gas residue, and debris can inhibit the burner's ability to function correctly, leading to premature failure. If cleaning the burner doesn't solve the problem, it may need to be replaced.
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 Burners / Flames go out
Your pilot light may be clogged (Try cleaning it). Inspect the fire's flue. It may have become partially or completely blocked. Tip: A drop in gas pressure may cause your gas fire to fluctuate, or even go out in extreme cases.
The major cause of a low flame is a clogged orifice. Spiders climb in when not in use and build webs. When the gas is turned on... the web is blown across the orifice opening. Typically the burner needs to be slid off the orifice for cleaning. Use a very small drill bit or pin or bristle of steel brush.
If the gas is on and the pilot hasn't been lit in a couple of months, you might need to purge the air out of the pilot tubing. To do this, hold the pilot button down for about one to three minutes while the air bleeds out. If the pilot is lighting but not staying lit, it could indicate a worn-out thermocouple.
There are several issues that could affect your boiler and cause it to stop igniting, such as faulty fan or gas valve, frozen pipes and others discussed in the following section. Try checking if your gas oven or hobs are turning on to check if your home has a sufficient supply.
If you see a small, continuously burning flame, that's the pilot light. Operating sound: Electronic ignition systems often make a distinct clicking sound when the fire is turned on, as it's sparking to ignite the gas.
So you've checked your pilot light and even reset it, but still, it wont stay lit. This can be an indication that your fireplace thermocouple is either bad or worn out. However, if your pilot is lit but the gas fireplace isn't, then there's probably a problem with your thermopile.
Gas fireplace repair costs can range significantly from $400 to $1500, depending on the problem you face.
But in general, an efficiently running modern gas fire kept clear of dust and debris should hit or exceed that 10 to 15-year mark before showing signs of wear. Older or cheaper models may start to struggle after 7–8 years. Regular servicing and maintenance will be essential to maximising lifespan potential.
Poor Draft: Things like blockages, creosote, and debris buildup – or possibly even small critters – can create a weak draft within the chimney. These things trap smoke and suffocate the fire, so your fire is likely dying before it really starts to heat your home.
A clogged or faulty burner can cause performance issues resulting in a low gas flame. In addition, carbon build-up, gas residue, and debris can inhibit the burner's ability to function correctly, leading to premature failure. If cleaning the burner doesn't solve the problem, it may need to be replaced.
By heating smaller zones with the fireplace, you use fewer BTUs, which means lower gas consumption and savings on your heating bills.
A healthy, properly burning flame on gas appliances should be blue in color, sometimes with a tiny tip of yellow, with a little light blue triangle at the center. This blue color flame indicates that there is safe, efficient and more complete fuel combustion.
If you notice uneven flame distribution in your gas fireplace, it is important to address the issue promptly. Start by checking for any obstructions or debris in the burner ports and clean them if necessary.
Safety. One of the main concerns about leaving the pilot light on during summer is the risk of carbon monoxide poisoning. Carbon monoxide is a colorless, odorless gas that can be deadly if inhaled in high concentrations. The pilot light can produce carbon monoxide even when no fire is burning in the fireplace.
Defective Igniter. The igniter is the part of the gas heater that starts the flame, and if it's defective, the heater won't work. Sometimes this can be fixed, but other times it might be best to replace the entire gas heater.
Clogged burner ports, a failing gas valve, low gas pressure, or an igniter failure are the most common problems. If you have a low gas stove flame, it is important to resolve the issue to find the cause. Once the root cause has been identified, you can take corrective action.
