There are three different styles of gas fireplaces: the direct vent model, the top vent design, and the vent-free model. The direct vent gas fireplace uses two vent pipes that lead directly to the outside. One pipe uses combustion air from the outside while the other vents the exhaust gas. The top vent gas fireplace design can be installed into existing fireplaces and uses the metal or brick chimney as the exhaust vent. The combustion air for top vent fireplaces is drawn from inside the home while the chimney vents the exhaust gas. The vent-free gas fireplace model uses no exhaust vent. This style includes an oxygen-depletion sensor that turns off the gas if it senses a dangerous lack of oxygen inside the house. While fireplace manufacturers claim that vent-free fireplaces burn clean, are energy-efficient and dont threaten indoor air quality, be aware that a number of states do not permit the installation of vent-free fireplaces. In the New England states of New Hampshire, Massachusetts, Vermont, Maine and Connecticut installation of vent-free gas fireplaces is permitted. Massachusetts has in the past not authorized the installation of vent free gas fireplaces for safety reasons.
Fireplace Inserts If you have a masonry fireplace but dont like the associated, draftiness, energy costs or overall inefficiency, you should consider purchasing a fireplace insert, sometimes referred to as a fireplace stove insert. A fireplace insert is basically a wood stove designed to fit into a fireplace. Fireplace inserts are usually constructed of cast iron or steel just like wood stoves. Installing a fireplace insert will typically require the installation of a chimney liner. The chimney liner essentially narrows and insulates the chimney vent and connects directly onto the fireplace insert creating a closed highly efficient system. No more opening and closing the damper. Fireplace inserts can use various fuel options and are clean burning (minimal smoke and particulate emissions). Fireplace inserts like wood stoves are heavy, usually weighing upwards of 300 pounds. This means delivery and installation are better left to certified installers or professional chimney sweeps.
If you decide that cleaning your chimney from the top will work better for you, you will need to have a long piece of rope and some type of weight attached to the bottom of the chimney brush. Again, as you work the brush through the chimney, use a back and forth motion to be sure you are scraping off as much creosote as possible. If you do choose to use this method, make sure that you do it with safety precautions in place. Falling off the roof is never a good idea! Chimney sweeps are another excellent option for cleaning your chimney. These professionals can make sure that all aspects of your chimney are up to safety standards. Look for a CSIA Certified Chimney Sweep in your area to ensure that your fireplace is properly cared for.
If you decide that sitting next to the fireplace is the way to go, you will need to make sure you have enough chimney rods to span the entire length of your chimney. As you are sitting next to your fireplace, push your brush up through the flue. Continue to add more brush rods as needed until the brush is at the top of the chimney. As you pull the brush back down, you will need to make a back and forth motion to really scrub the creosote off the walls of the chimney. Be sure to shield your eyes, as some of this loosened creosote may fall into the firebox.
