What is a Fireplace Insert?

A fireplace insert is a device that is inserted into an existing masonry or prefabricated wood fireplace. It's designed to make your fireplace work more efficiently at heating your home. Think of it as a stove that fits inside your fireplace. They come in different types like gas, wood, or electric. If your fireplace insert isn’t working right, it can turn from a cozy feature into a real hassle.

Common Issues with Fireplace Inserts

Here are some common problems you might run into with your fireplace insert:

  • Smoke entering the room
  • Poor draft
  • Not enough heat
  • Weird odors
  • Creosote buildup

Let’s look at each problem in a bit more detail and figure out how to fix it.

Troubleshooting Fireplace Insert Problems

Problem 1: Smoke Coming into the Room

If smoke is coming into your room when you use your fireplace insert, that’s a big issue. Here’s what you can do to troubleshoot:

Check the Flue

The flue needs to be open when you are using the fireplace. This might sound simple, but sometimes people forget. Make sure to check the flue’s position.

Inspect the Chimney Cap

A chimney cap helps keep out rain, debris, and animals, but if it's blocked, it can stop smoke from exiting properly. You might need to get on a ladder or call a professional to check it out.

Look for Blockages

Sometimes, debris or even bird nests can block the chimney. If you hear chirping or see sticks and leaves, that could be a problem.

Consider the Weather

Believe it or not, weather can affect how smoke moves. On really windy days, the wind can push smoke back down your chimney. If this happens often, you might need a special chimney cap to help with this.

Problem 2: Poor Draft

When your fireplace isn't drawing properly, it's called a "poor draft." This can lead to smoky rooms and poor heating.

Check the Chimney Height

The height of your chimney can affect the draft. A chimney that’s too short might not draft well. There are specific regulations and recommendations for chimney heights, so make sure yours meets those standards.

Inspect for Obstructions

Blockages in the chimney can cause drafting issues. Regular sweeping and cleaning can help prevent this. If you're not comfortable doing this yourself, call in the experts.

Adjust the Damper

The damper controls the amount of air entering the chimney. Make sure it’s in the right position. A damper that's too wide open or too closed can affect how well your fireplace drafts.

Problem 3: Insert Not Heating Properly

If your fireplace insert isn't heating your home as it should, here are some steps you can take:

Clean the Fireplace Insert

Over time, ash and soot can build up inside the insert, making it less efficient. Regular cleaning can help. Make sure to clean the firebox, glass doors, and any vents.

Check the Insulation

Your insert should be properly insulated for it to heat efficiently. Insufficient insulation can lead to heat loss. Sometimes, you may need to add more insulation or replace old, worn-out insulation.

Look at the Fuel

If you're using a wood-burning insert, make sure you're using dry, seasoned wood. Wet or green wood burns less efficiently and produces more smoke. For gas inserts, ensure the gas supply is adequate and that the burners are clean.

Problem 4: Strange Odors

Your fireplace insert shouldn’t produce any weird smells. If it does, here’s what to check:

Look for Animal Nests

Sometimes, animals can nest in your chimney. This is especially common in unused chimneys. If you suspect this is the case, you might need a chimney sweeping.

Inspect for Mold

Mold can grow in damp chimneys, especially if there has been water leakage. If you smell something musty, there might be mold.

Burn the Right Fuel

Burning inappropriate materials like trash, painted wood, or wet wood can create strange odors. Always use the right type of wood or fuel recommended for your insert.

Problem 5: Excessive Creosote Buildup

Creosote is a black, tar-like substance that builds up inside your chimney and fireplace insert. It's flammable and can cause chimney fires if not cleaned regularly.

Regular Cleaning

Set up a schedule for regular chimney sweeping and cleaning. The National Fire Protection Association (NFPA) recommends cleaning your chimney at least once a year.

Use Seasoned Wood

Always use dry, seasoned wood in your wood-burning fireplace. Wet wood produces more creosote. Seasoned wood has been dried for at least six months and is lighter in weight.

Install a Chimney Cap

A chimney cap can help keep out moisture, which contributes to creosote buildup. It’s a small investment for a big safety payoff.

Regular Maintenance Tips

Regular maintenance can prevent many of the problems we've discussed. Here are some tips to keep your fireplace insert running smoothly:

Professional Inspections

Have a professional inspect your chimney, fireplace, and insert at least once a year. They can catch problems early before they become big issues.

Clean the Firebox

Clean the firebox regularly to remove ash and debris. This helps your fireplace work more efficiently and reduces the risk of fire.

Monitor for Cracks

Check for cracks in the masonry or the insert itself. Cracks can let harmful gases into your home and reduce the efficiency of your fireplace.

Check the Chimney Cap

Inspect your chimney cap regularly to make sure it's in good condition. Replace it if it shows signs of wear.

When to Call in the Experts

While a lot of troubleshooting and maintenance can be done by yourself, some issues are best left to the experts. Here’s when you should give us a call:

Structural Damage

Persistent Problems

If you've tried troubleshooting and the issue persists, it's time to call in the pros. Sometimes, the root cause is more complicated than it seems.

Safety Concerns

Any time you have safety concerns, like a chimney fire, smoke in your home, or gas odors, contact a professional immediately. It's better to be safe than sorry.

Annual Maintenance

Annual inspections and cleanings are crucial to keep your fireplace insert working safely and efficiently. Schedule these regularly with a professional service.
