Getting Optimum Draft

Your Chimney’s Draft, And How It Can Be Compromised

As comprehensive chimney and fireplace service professionals, the techs at the Chimney Care Co. tend to talk about draft a lot — it’s pretty much the key to your chimney’s proper function, so maintaining draft is key to what we do, too.

The Chimney Safety Institute of America has a detailed breakdown of the science behind how your chimney works, but if you want the chimney draft CliffsNotes, here’s a simple breakdown.

Not only does optimum draft increase effectiveness and performance, it also minimizes risks.

Not only does optimum draft increase effectiveness and performance, it also minimizes risks.

Draft is, more or less, how air draws up your flue. And it occurs because of a difference in pressure between the hot air produced by your fire and the cooler air outside your flue. When heated air is getting produced by your fire, some degree of draft will happen, but what you really need is optimum draft — the proper level of upward pull, which happens when your chimney system is properly built, in top shape, under optimum burning conditions.

That probably sounds like a tall order, all those optimums. But that’s what we do at the Chimney Care Co.: We use the right methods, tools and expertise to get your chimney system set up for optimum draft.

What Can Stop Optimum Draft?

Ensuring optimum draft means getting rid of all the things that hinder draft. Wondering what those things are? Here are a few of the most common problems:

Blockages

This one’s kind of a given: If something is blocking off your flue, air can’t flow like it should. The most common flue blockages are usually an indication of another problem, like a missing chimney cap allowing animals to nest in the chimney, pieces of a damaged chimney liner falling into the flue, or excess amounts of creosote being present because of an overdue chimney sweeping  appointment.

Improperly Sized Flue

Heating appliances are designed to vent through a specifically sized flue. A flue that’s too small leaves you with weak draft and smoking issues. A flue that’s too large generally draws too slowly leading to poor venting, increased levels of creosote and often liner and masonry damage from acidic condensate, too. The mismatch in sizes sometimes happens when a new appliance is installed to vent with an existing chimney, and the flue size isn’t taken into consideration. The most effective solution: having a new stainless steel flue liner installed to bring the flue to its proper size.

Your Appliance Isn’t Getting Enough Air

Fireplaces and stoves need combustion air to encourage draft and keep byproducts and smoke moving in the right direction. If you’re having issues with smoke coming into your living area and your home has energy-efficient windows and doors, those energy savers might be keeping your fire from getting enough air. Try cracking a window and see if it helps.

You’re Using The Wrong Fuel

If you have a wood-burning appliance, here’s one rule that has no exception: Burn seasoned or kiln-dried wood, always. Burning improperly dried wood leads to a fire that doesn’t burn hot enough, which means a weak draft and increased creosote. If you’re collecting and cutting your own wood, let it dry for six months to a year. (Christmas trees and trash: also a no-no as far as proper fireplace or stove use goes.)

If you’re experiencing draft issues, The Chimney Care Co. technicians can inspect your system, find the culprit and offer solutions. If you’d like to schedule an appointment, or ask any questions, just give us a call!

Maintaining Your Fireplace Safely

Fire Prevention Tips

Building a fire in the fireplace is a great way to enjoy a winter night, but many homeowners have had that experience turn into a catastrophic situation. If a fireplace and chimney are not properly used and maintained, you put yourself at risk. There are a few simple tips that any homeowner can follow to make sure that their fire remains in the fireplace.

One way to maximize your safety is to only burn dry, seasoned wood. Wet or green wood produces excess creosote, which is highly flammable.

Getting Started

Before using the fireplace for the first time each season, it is a good idea to check the batteries in the smoke detectors. This is something that all homeowners should be doing every month anyway but it is especially important during the winter season. No matter how careful a person is, accidents can still happen and it is important to be prepared. Knowing about the beginning of a fire as soon as possible is the best way to minimize the damage.

Cleaning Out Creosote

Another important thing to remember is that a fireplace and chimney must be kept clean if they are going to function properly. This is why most homeowners opt to have a licensed chimney sweep clean out their chimney at least once a year. A chimney sweep is equipped to deal with things such as creosote, a dangerous chemical compound that is often left behind after a fire. Creosote, as well as other materials often found in chimneys, is extremely flammable and has been known to start many chimney fires.

What Not to Do

When there is a fire blazing in the fireplace, it can be tempting to throw in material that has been lying around and is need of disposal. However, only material intended for burning in a fireplace should be placed into the flame. This means only treated coal and properly seasoned hardwoods. Using anything else could not only damage the structure of the fireplace, but it could start a blaze that quickly gets out of control. Be sure to keep a screen around the fireplace so that children cannot throw in toys or other unwanted materials.

Invest in a Chimney Cap

Many chimney fires start as a result of a blockage that prevents smoke and other combustible gasses from properly exiting the fireplace. This blockage may be caused by leaves that make their way into the chimney or by animals that decide to use it as their home. A chimney cap is a small, simple structure that goes on top of the chimney and prevents these things from entering the chimney. It is a small investment that makes a big difference.

Have Your Chimney Inspected

The most important thing a homeowner can do for their chimney and fireplace is to have it inspected each year by a licensed chimney inspector. This is the only way to get a good look inside of the flue and see if there are any issues on the horizon. Catching potential chimney problems in the early stages can make the repairs less costly and can also decrease the risk of danger to the home.

Having a fireplace in the home is a great perk for a homeowner who knows how to properly use and maintain it. Annual inspections are a necessity as well as keeping the flue and fireplace as clean as possible. Installing a chimney cap is a great way to make sure that all flammable material can leave the fireplace as it should.
