Pictured: an old fireplace insert known as a slammer, installed without a liner. We were called out to inspect after the fire department was called as the creosote surrounding the stove had caught on fire. The land lord had a handy man clean it every year and he had just had it cleaned.
The cozy glow of a crackling fire is a winter staple, but not all fireplaces are created equal. In the past, a popular "fix" for inefficient fireplaces was the fireplace insert slammer. While these offered a seemingly easy solution, they harbored serious dangers that are crucial to understand, especially if you're considering upgrading your fireplace.
What is a fireplace insert slammer?
Imagine a metal box – the insert – that simply slides into your existing fireplace. This "slammer" lacks a proper chimney liner and relies on the existing masonry to vent smoke and gases. While it might seem like a quick and cheap way to boost heat output, it's a recipe for disaster.
Why are fireplace insert slammers dangerous?
Chimney fires: Slammers don't provide proper air control, leading to incomplete combustion and excessive creosote buildup in the chimney. This highly flammable substance can easily ignite, causing a chimney fire that can quickly spread to your home.
Carbon monoxide poisoning: Improper venting allows harmful carbon monoxide (CO) to leak into your living space, posing a serious health risk. CO poisoning can cause headaches, dizziness, and even death.
Inefficient heating: Slammers often don't create a proper seal, leading to heat loss and wasted fuel. You might end up using more wood for less warmth, negating the intended benefit.
So, how do you fix a fireplace insert slammer?
The good news is, there's a safe and effective solution: professional installation of a properly vented insert. This involves:
Removing the slammer: Get rid of the outdated and unsafe insert.
Installing a chimney liner: A properly sized and certified liner ensures safe and efficient venting.
Installing a new, EPA-certified insert: Choose an insert that meets modern safety and efficiency standards.
Relining Isn't an Option:
Thinking of relining your slammer to address these issues? Think again. Due to their design and inherent safety flaws, relining a slammer simply doesn't meet current safety standards. It's like putting a Band-Aid on a gaping wound – it might look okay on the surface, but the underlying problem persists.
Colorado Says No to Slammers:
Here in Colorado, fireplace safety is taken seriously. Under Regulation No. 4 of the Air Pollution Control Division, the use of unlined fireplace inserts is prohibited. This means that if you have a slammer in your Colorado home, replacing it with an EPA-certified stove is mandatory, not optional.
Upgrading for Safety and Efficiency:
Replacing your slammer with an EPA-certified stove is not only about complying with regulations, it's about prioritizing the safety and well-being of your family and home. Modern stoves offer:
Safe and Efficient Venting: Proper liners ensure smoke and harmful gases are expelled safely, reducing the risk of chimney fires and CO poisoning.
Cleaner Burning: EPA-certified stoves meet strict emission standards, minimizing air pollution and creating a healthier environment.
Improved Performance: Modern stoves are designed for efficient heat output, meaning you'll get more warmth with less fuel.
Making the Switch:
While replacing your slammer might seem like an inconvenience, consider it an investment in your safety and peace of mind. Consult a professional chimney sweep or fireplace professional for proper inspection and guidance on choosing the right EPA-certified stove for your needs.
Remember, enjoying the warmth of a fireplace shouldn't come at the cost of safety. Ditch the outdated slammer and embrace a modern, safe, and efficient heating solution for your Colorado home.
