Wondering what type of gas fireplace you should install? Below is some information on the two different options that Rodman’s offers, including how they work and what you might need to know before you put one in your home.
Direct Vent Gas Fireplace
Direct vent gas fireplaces do not need a traditional chimney. This type of fireplace has a completely sealed combustion chamber, which allows it to vent out through a side wall, or up through the ceiling. This makes installation more flexible, since you have more options for where to put your fireplace, and it helps keep installation costs down. Direct vent gas fireplaces bring their combustion air in from the outside of your home, and also vent to the outside. This means they do not use up warm house air, and do not compete with other household appliances or your furnace for combustion air. They are your best choice if you want to install a gas fireplace in the basement.
Natural Vent Gas Fireplace
Natural vent (or natural draft) gas fireplaces take in air from inside the home to use for combustion, and then vent to the outside. They are also known as B-Vent fireplaces. If you already have a vertical chimney, you can just use a less expensive flexible aluminum or stainless steel liner to vent the exhaust up through the chimney. If you don’t have a chimney, you need a B-Vent pipe that goes through the wall and then up above the roof. Natural vent gas fireplaces also have a draft hood or draft diverter, which requires extra air from your house to isolate the burner from changing draft conditions. The draft hood draws more or less air in as required, which ensures that the burner has a constant air supply, regardless of outside temperature changes or wind.
Gas Fireplace Maintenance
Regardless of the type of gas fireplace you choose, proper maintenance is key to ensuring its energy efficiency, safety and longevity. Some people think vacuuming out the unit is sufficient, but in order to ensure the combustion venting, gas pilot safety system and other parts of the fireplace are in optimal working order, it is wise to have a certified gas technician clean and inspect the unit.
