Can Gas Fireplaces Cause Headaches? Safety Tips for All

Yes, gas fireplaces can cause headaches. This is because of the dangerous fumes that are produced during the combustion of fossil fuel. The main agent that causes headaches is carbon monoxide. The main byproduct of the oxidation process.

Improper maintenance of a gas fireplace can cause the incomplete combustion of fuel hence a lot of fumes in the room. Once you inhale such fumes, they take up oxygen in your blood. The low oxygen content in your brain cells is what causes headaches. 

The incomplete combustion of the fuel is not a normal thing. A problem must be somewhere with the whole system. Improper maintenance is the main reason you will find high carbon monoxide in the air. This article will give you possible problems with gas fireplaces that lead to the accumulation of fumes in your home.  

Possible Problems with Gas Fireplaces

Gas fireplaces are designed to produce zero fumes for the user. But once you start feeling the difference in the air you breathe then something is wrong with the whole system. Below are some of the possible problems that can cause fumes with your gas fireplace. 

  1. The pilot light is not working 

The pilot light is what ignites the whole system. This is the spark that ignites the fuel that is flowing through the system. Some gas fireplaces have a small flame as the pilot light. Open the vents and see if the flame is present. If not, use an ordinary match to light up the pilot light. 

The pilot light not working is mainly caused by moisture build-up in the pipes. To correct this, go to the gas meter and find a pipe called the tee. The tee is a capped pipe that retains moisture. Just clean this pipe and the pilot problem will be over. 

  1. Airflow and chimney problems

This mainly happens to vented gas fireplaces. This type of fireplace has a chimney. The chimney allows the hot air to rise while the cool airdrops. Once the chimney is not functioning then it means some hot air will not leave the fireplace. The hot air left behind is radiated back to the fuel lowering the fuel temperature. 

This fuel with low temperature is what causes condensation and release of fumes back into the room. The imbalance of pressure in your home also causes the chimney to malfunction. 

  1. Improper inspection and maintenance 

A gas fireplace requires regular inspection and maintenance. You have to inspect the gas lines, the chimney, and any other main parts to see any possible problem.

  1. Pet hair and dander accumulation 

Pets like cats and dogs shed down their hair, these hairs sometimes accumulate on the burner and chimney. The situation can be bad when they suck up in the gas pipes causing a blockage. Blocked pipes are very dangerous and can lead to a fire or explosion. You are advised to regularly clean the gas logs.  

  1. Dead batteries 

Yes, a gas fireplace has batteries. There are a set of replaceable batteries at the back. These batteries power the receiver of the remote control. When your gas fireplace is not working, change the batteries in the receiver and in the remote control. And try again to power it on.
