The other option, vent free fireplaces, heat efficiently and release limited by-product into the air around you. Though, they have limited output and are banned in many states due to concerns about exhaust fumes being released into the room. So, direct vent fireplaces are a great happy medium where you get heat efficiency and good air quality.

Are there multiple styles of direct vent fireplaces? 

While some consider fireplaces fueled by gas to be faux fireplaces, the benefit to the artificial flame models are a wide variety of styles. So, if you have to give up the authentic look of a wood burning fireplace, you won't have to scrimp on the overall aesthetics of your appliance.

How do I care for my new fireplace?

INSTALLATION:

While the owner's manual will give you invaluable tips for maintaining a direct vent fireplace, you will need to contact an electrician to run a gas line and help you complete the installation. There are clearances required for installing a venting system as well as specific framing dimensions to be aware of when creating the opening for your new fireplace. This is not a job you want to tackle alone unless you have significant experience in home renovation.

CLEANING:

Thankfully, cleaning a gas fireplace isn't as hard as installing one. Exhaust fumes that escape through the chimney from a gas fireplace aren't nearly as tough on the flue as gases that release from a wood burning fireplace. So, you won't have to worry about creosote build up in the chimney and only need to inspect the system termination occasionally. You'll want to check for yard debris or bird nests in the venting system about once a year. Don't forget to clean the glass 1-3 times per year with water and a soft cloth.
