Why Does My Gas Fireplace Have a Small Flame?

A gas fireplace is a one-of-a-kind addition to any house, particularly those in colder regions. It can be annoying, though, when the flames aren’t as powerful and warm as they should be.

Weaker flames in a gas ventless fireplace might be caused by residue buildup or gas line connection issues. These issues might result in burner obstructions or inadequate gas, causing the fireplace to produce lesser flames.

The remainder of this article will assist to address this issue more thoroughly by offering information on other important subjects such as how gas fireplaces function, the particular sources of tiny flames and how to detect them, and how to remedy this problem.

What Is The Process Of Using A Gas Fireplace?

When it comes to home heating, the development of the gas fireplace was a watershed moment. Gas fireplaces are a highly efficient type of heat since they do not create heat from the air in the home, do not require a wood supply, and provide enough heat to obviate the need for another heating source.

Gas fireplaces operate by connecting to a gas line, which, when coupled with an air supply, produces flames that may be regulated through remote control. To offer a genuine feel, these fireplaces also employ fake logs that imitate wood logs. While most gas fireplaces operate in the same manner, there are several types of gas fireplaces to select from.

Gas Fireplaces With No Vents

A ventless gas fireplace is still fuelled by gas, utilizes fake logs, and produces enough heat to heat a room. Ventless gas fireplaces, on the other hand, do not use vents to draw in fresh air for burning or to exhaust polluting air.

Ventless fireplaces, on the other hand, take oxygen from the room’s air to produce heat and then recycle the air back into the room through holes in the top and bottom of the fireplace. While these gas fireplaces are a viable choice for houses without chimneys or venting, it is suggested that the home’s air quality be constantly monitored to track oxygen and carbon dioxide levels.

Gas Fireplaces With Vents

Vented gas fireplaces are a popular and energy-efficient way to heat a house. These, like ventless gas fireplaces, do not have a chimney and use fake wood to create a sustainable heating source and genuine atmosphere. In contrast to ventless gas fireplaces, models with vents draw in air from outside the home to create heat and exhaust waste via the vent. As a result, no air from within the house is needed to power the fireplace.

What Are The Most Common Causes Of Minor Fires?

Several potential issues might even result in tiny flames on a gas fireplace. It is critical to establish the cause before determining the treatment.

Gas Pressure Is Low

Because gas fireplaces require gas to work, if the gas line to which the fireplace is attached does not provide enough gas, the flames produced in the fireplace will be less. This might happen as a result of a faulty pipe connection, a blockage in the pipe, or another problem with the gas hookup.

Vent Is Obstructed

If there is any obstruction to the vent that connects to the exterior of a vented fireplace, the fireplace will not be provided with enough air to generate proper combustion, resulting in lesser flames. Obstructions can occur as a consequence of things being trapped inside the vent, vent damage, or anything blocking the vent from the outside, such as snow.

Cleaning Required

Even while gas fireplaces emit less waste than wood-burning fireplaces, the residue can accumulate over time and clog the gears that generate heat. Furthermore, much like any other household item, dust and lint can become trapped within the fireplace, causing further obstruction.

Finding The Root Cause

It is advised that to discover the problem, you inspect the various components of the fireplace system and look for any damage or obstructions. This involves inspecting the logs, gas pressure valve, and vent (if applicable). Cleaning the logs may assist if the fireplace hasn’t been cleaned in a while. Important note: whenever you access the interior of the fireplace system, be sure to turn off the gas valve as a precaution.

How To Solve These Issues

Fortunately, there are solutions to repair any problems with a gas fireplace that may be causing tiny flames. In the event of a gas connection or pressure problem, calling the gas company might be beneficial in ensuring that everything linked to the fireplace’s fuel supply is functioning properly. If there are other gas-powered appliances in the home, problems with gas pressure or hookup are typical. If a vent is obstructed, make sure the passage to the outside is unobstructed. 

Also, ensure that the vent hole leading to the logs within the fireplace is properly installed and functioning. If this component is obstructed or broken, the air from outside may not flow enough into the fireplace. Finally, cleaning the fireplace itself is never a bad idea. The next part will describe how to clean a gas fireplace to guarantee proper operation.

Cleaning A Gas Fireplace

As previously stated, while gas fireplaces with fake logs do not produce nearly as much residue as wood-burning fireplaces, particles can still accumulate over time. With a few basic supplies, gas fireplaces may be cleaned thoroughly at home. A gas fireplace may be cleaned with tools such as warm washcloths and any type of duster.

Before cleaning, turn off the gas valve (the gas pilot light should go out) and make sure the logs are cold. Then, disassemble the fireplace, including the wood and the burner. Most gas fireplaces can be easily constructed and disassembled, but have instructions on how to do so on hand just in case.

To remove any dust or lint that has accumulated on or around these components, use a duster or cloth. A vacuum can be used to clean the area surrounding the logs if necessary. If the fireplace has glass, it may be cleaned with warm water or a similar glass cleaner. After cleaning the separate pieces, reassemble the fireplace and reactivate the gas valve. The pilot light should turn back on. A gas fireplace may be cleaned as frequently as once per month for best results to avoid future functioning difficulties.

Fixing difficulties that may be producing a tiny flame in a gas fireplace is doable, despite the fact that it might be irritating. By checking for gas connection issues, obstructions in any air vents, and doing a thorough cleaning, the fireplace should be restored to good operating order, leaving the area toasty and cozy once again.
