Still about gas fireplace inserts, having decided to clean up the look of your existing wood burning fireplace, by retrofitting a gas-fired insert, you have so many things to think about, you may want to forget the whole idea.

If you’ve been using the wood fireplace extensively instead of gas fireplace inserts? It’s always a good idea to have the chimney cleaned, just one more time, before the gas insert is installed. Some hearth stores offer that service at a reduced rate if you’re buying a gas insert from them.
The Unit Types:
The gas fireplace inserts are divided into a couple of types: A conventionally vented and direct vented or sealed combustion type.
In this case, the conventionally vented provide fewer performance problems. They are almost all equipped with a four inch aluminum flex vent from the unit to the top of the chimney. The four inch flex effectively resizes the chimney for the reduced volume of products of combustion produced by gas inserts as compared to the smoke, heat, dilution air and other products of combustion drawn into the chimney from a roaring wood fire.
More detail in talking about the gas fireplace inserts, we will talk about retrofitting a wood burning fireplace. Since you are retrofitting a wood burning fireplace which used much more air than a gas insert will, it is unlikely that there is an air supply problem to the room it is going into. Natural infiltration around windows and under doors is usually sufficient to accommodate the amount of air required for complete combustion and dilution air through the draft divertor into the chimney.
What about the second type of gas fireplace inserts called direct vented inserts? Usually, it will use two or three inch diameter aluminum flex vents from the unit to the top of the chimney. One vent is used for exhaust and the other for bringing in combustion air. Such type will be highly recommended if you are living in a tightly sealed home and you are concerned about availability of combustion air to the fireplace.
