How to Signs of Over Firing Wood Stove

Wood stoves are a great way to heat your home, but it is essential not to overfire them. Over firing a wood stove can cause the chimney pipe to crack and release dangerous carbon monoxide into the air. The following article will provide you with some helpful tips on how to avoid overfiring your wood stove. 

How to Signs of Over Firing Wood Stove

In this post, we will discuss how to signs of over firing wood stove. We also have instructions for how you can reduce the risk of having a cracked chimney pipe by making sure there is sufficient airflow in and out of your house while using your woodstove. If you follow these guidelines, you should enjoy wood heat for many years to come.

10 Steps to Follow on How to Signs of Over Firing Wood Stove

Step One: Keep Fire Alive

Keep the fire alive, not an easy job. First, the wood has to be constantly monitored and added as needed. Second, the stove should absorb all moisture from the air during warm months of the year, but when the temperature dips below zero, a good supply of dry firewood is needed to keep the fire going through the night.

Keep The Fire Alive

The stovepipe has to be kept clear of any blockage, and a yearly check-up is an excellent idea for a safe heating season. Well. White or gray smoke coming out of the chimney can indicate a problem and should be addressed as soon as possible. The signs of an over-firing wood stove are that the smoke turns black or dark gray.

Step Two: Watch the Fire

After several hours of burning, some stoves will start to smoke. This is not usually the result of overfiring; it’s a sign that creosote buildup is taking place inside the stovepipes and chimneys.

Fires need to be watched at all times, but mainly when the temperature is below zero. Fires are easy to keep going at this time, but they are tough to stop once they have been going for a good length of time.

Step Three: Check the Draft

Check the draft, which controls the flow of air that feeds the fire. A strong draft means oxygen is being sent to the fuel. This will eventually cause problems if it’s not controlled by closing down one of more dampers or partially closing them. A weaker draft means there is not enough oxygen for the fire. If the draft is too weak, shut down an air control or two to increase airflow.

If your stove has no dampers, you’ll need to open a window slightly for additional oxygen. The primary cause of overheating is the lack of airflow. When the firebox glass begins to glow red hot, this means almost all the available oxygen has

Step Four: The Firebox

If the firebox has been overfilled with firewood, it will lead to black smoke. More wood should never be added to a hot stove because it can cause an over-fire condition that results in black smoke every time the stove is used.

The Firebox Has Been Overfilled With Firewood It Will Lead to Black Smoke

Put the wood in a well-vented area, and let it season for at least six months. It is essential to have the right amount of firewood on the stove at all times. Less firewood will result in a weak draft, which means less airflow across the burning fuel. This will cause longer burn times and increase the possibility of overheating.

Step Five: The Chimney

If the chimney has been closed for a long period, creosote will build up faster. A fireplace should be cleaned yearly during the heating season to avoid having your stove damper become blocked by rust or just plain creosote buildup. Also, when it gets cold outside, you want to avoid shutting down the fireplace for more than two weeks.

Shutting it down for more than two weeks will increase the creosote buildup to an unacceptable level. It is essential to make sure that all flues are open before lighting your stove during startup. If you have a direct vent, avoid back-drafting into the room by opening windows slightly when starting your fire. The moisture in the air will cause a weak draft if the windows are not open slightly.

Step Five: Keep the Firebox Clean

Keeping the firebox clean is another essential factor in avoiding an over-fire. Creosote will build up quickly and decrease draft, which could lead to overheating problems. If you have a catalytic combustor, monitor it closely for soot buildup because this could indicate a clogged catalyst element inside the stove.

Keeping the Firebox Clean Is Another Essential Factor

If you have a catalytic combustor, monitor it closely for soot buildup because this could indicate a clogged catalyst element inside the stove. Overfiring is the most common cause of wood stove problems. When you have an over-fire, the fire spreads beyond the confines of the firebox and can burn on top of your hot coals, either directly or indirectly, through flue gases.

Step Six: Know When to Call a Technician

If you have followed all the steps above but are still experiencing overheating problems when lighting your stove, it is time to call in professional help. Overheating can be caused by inadequate draft or something else blocking airflow, which means that it’s not always easy to solve without professional assistance.

How Can I Tell if My Wood Stove Is Overfiring?

The most common sign of overfiring a wood stove is black smoke coming out of your chimney.  This means that you have been burning your log for too long or at too high of a temperature.  It would help if you always extinguished your fire before it became too hot or burned for more than 3 hours.

Another sign of overfiring is if your logs are not burning well.  This may mean that you are trying to burn too large of a log or that it is wet.  If this happens, allow your fire to die down overnight and try using smaller pieces the next day.

How Do I Know if My Wood Stove Is Under Firing?

The most common sign of underfiring a wood stove is not having enough heat in the house, even after a full 24 hours of burning. Therefore, you should always ensure that your wood stove has been properly and completely loaded before lighting it up.  If it is underfiring, you may need to add more wood or open your air vents.  If the fire is not burning efficiently or hot enough, it is probably under firing.

What Causes Over Firing?

The main cause of overfiring a wood stove is loading the kindling/wood too tightly or too loosely.  If you load them too tight, not enough air can get in to combust the wood, which means that burning will stop.  If you load them too loosely, the fire can grow larger than what is needed for a nice and steady burn.  

The main cause of overfiring, in either case, is the damper since, without it, you would be able to load your wood much more loosely. Thanks for reading about how to signs of over firing wood stove.
