Minneapolis Chimney Tip: How to Maintain Proper Airflow in Your Chimney

Monday, October 15th, 2012

Whether you heat with gas, wood, or pellets, proper airflow in your chimney is important for several reasons. Not only does it help with efficiency, but it can also prevent backdraft and fire hazards. Here are some ways you can ensure that you are getting proper airflow in your chimney.

At 2nd Generation Chimneys, our Minneapolis chimney specialists are here to answer any further questions you might have. Our technicians are trained and certified to inspect chimneys for any type of heating system that requires ventilation through a chimney, so feel free to contact us any time.

Make Sure the Damper is Fully Open

Before you turn on your heat or build the first fire in the fall, always make sure that the damper is fully open. After you open it, check to make sure it’s fully open. Often a damper won’t open all the way because of excess creosote or soot buildup on the smoke shelf, or the damper could be damaged.

Schedule Your Annual Chimney Cleaning Before the Heating Season

In addition to checking for damage to the damper or other components, hiring a professional for a thorough chimney cleaning and inspection before the weather gets cold is important for many reasons. This gives the technician a chance to clean out dangerous levels of creosote build-up, and check for other issues with airflow. Poor chimney design is another issue that can be remedied in several ways. A damaged chimney cap or animals living inside the chimney are other potential airflow blocks.

Have Your Chimney Repaired as Needed

Should you need a chimney repair, it is important to have the repairs done before you use your heating system for the first time in the fall. This ensures proper airflow and safe operation. If there are cracks in the lining or your chimney needs masonry repairs, it’s also important to have this done since moisture can damage the inside of the flue or fireplace.

Increase Airflow by Making a Hotter Fire

The draft in your chimney works by pulling the air up through the chimney, so an easy way to increase the airflow is to burn hotter fires. Because hotter air is lighter, it creates more pull. If your chimney is too short or narrow for the heating unit, it can also affect the airflow and draft.

Make Sure Your Home is Properly Sealed and Insulated

Having a home that is sealed too tightly or one that has too many cracks and air leaks can disrupt the pressure inside the home, which also affects the draft.

Why Most Prefabricated Fireplaces in Cambridge Cannot be Installed Using the Existing Chimney System

Thursday, March 22nd, 2012

If you are looking to add a charming touch to your home, or just supplement your current heating system, you may be considering installing a fireplace. Since building a new fireplace is often costly and requires a lot of masonry work, many people are opting for prefabricated fireplaces instead.

Prefab fireplace units are nice, because they are convenient, they look charming and they work well. However, some people assume that because they already have a chimney in their home from a previous system, adding a prefab system will be easier and not require a new chimney. Generally, though, this is not true.

Most prefabricated fireplaces are sold as a unit along with an accompanying chimney, and they often will now work with another chimney system. There are a few reasons for this, such as:

  • Rigorous fireplace inspections and testing is a must for each home to ensure that they are safe to use. This testing is done along with the included chimney, so both are rated as safe together. The fireplace is not necessarily tested to be safe with any other configuration.
  • The specifications for air space and insulation in a fireplace are exacting, because of the volatile nature of the combustion process. Because a prefabricated fireplace and chimney are engineered to work together, you can be sure they meet the proper specifications.
  • The chimney and fireplace have been designed to work together for maximum efficiency, so any other setup could affect the performance of your fireplace and therefore the warmth of your house.
  • Because of the necessary clearance measurements mentioned above, wood is kept a certain specified distance away from the chimney. If a prefabricated fireplace is used with a different chimney, this clearance may be too short, which can cause chimney fires or other unsafe conditions.

Even with all this in mind, a prefabricated fireplace may still be the best option for you. It is just important to know up front that trying to save money be using an existing chimney system will not work and you are better off purchasing the whole bundle as sold.  If you have any questions about your fireplace please call 2nd Generation Chimneys.

Blaine Residents Ask: What is the Difference Between the Different Levels of Chimney Inspections?

Friday, February 10th, 2012

When needing a chimney inspection, many Blaine homeowners balk upon seeing the different levels involved.

How do I know which one to get? Which one s right for me? What is the difference?

To help answer those questions, let’s briefly describe the the levels of chimney inspection defined by the National Fire Protection Association.

Level 1

Also known as a visual chimney inspection, this is the most basic level. This inspection includes looking at all parts of the chimney that are readily accessible, both on the interior and exterior. The visual inspection is generally just done by eye, with no video equipment involved.

The idea is to inspect the overall soundness of the chimney and fireplace or stove installation. You would opt for this inspection if your system has been serviced frequently and you haven’t made any changes to the ventilation system or how you use your fireplace.

Level 2

As you would expect, this inspection is more involved. For this, an inspector will look not just at the readily accessible interior and exterior portions of the chimney, but also less accessible segments. This may include having access to an attic, basement or crawl space. This inspection is usually recorded on video.

You would need this type of inspection if you had made any change to your system, such as getting a new fireplace or changing the ventilation. A Level 2 inspection is also highly recommended when selling your home.

Level 3

The Level 3 inspection is the most thorough and involved. In addition to checking all the same areas in the first two levels, this inspection essentially means inspecting the entire chimney inside and out to determining if you need any chimney repairs.

This type of inspection is really only necessary in cases where the chimney has been or may have been damaged, such as in a house fire, chimney fire or natural disaster. So, with any luck, you will not have to have a Level 3 inspection ever performed on your chimney.

Please keep in mind that these are only general guidelines. The actual definitions of the inspections are much more complicated. If you have any doubt as to which inspection level is appropriate for your situation, call 2nd Generation Chimneys to make sure.
