Hello, new to the forum. Have been reading for the past few days. Lots of really good info, lots of nice people. I have done a search and tried to find out as much info as I can regarding inserts for zero clearance fireplaces. I am sorry to say that there is not allot of info out there, and it seems there is not allot of models available for zero clearance fireplaces. My home is 6 years old, and this past winter I have burned nearly every day. I have glass doors on the fireplace, so I feel pretty good about going to bed with a dying fire unattended. I do secure the doors to prevent a gust of wind accidentally opening them while I am not in the room. I have mastered the use of a couple of fans (one ceiling and one free standing) to help move the heat and it did save me $$ on the gas bill this winter. Wood supply is not a problem and I enjoy gathering, cutting, splitting and stacking. It's good exercise. While doing my homework, I discovered that the fireplace is extremely inefficient, and that a free standing or an insert is the way to go. At first I was going to go with a free standing unit, but I do not like how it will take up floor space in the room I plan to install it in, and I would need to rework my current prefab chimney. (I understand I need to add another liner for the insert) I then learned that I could use an insert, and it seems that the model I have found will fit my fireplace and seemingly my needs. It is a Country Flame model O2 at http://www.countryflame.com/ Unfortunately, I can not direct link to the unit so you need to click on "wood stove inserts" on the left, then the model "O2" I called a few of the dealers that the company listed for in my area. They were not the best help. Very little experience with this model, which does surprise me considering the amount of homes in my area that have builders basic zero clearance fireplace. None of the dealers were able to provide me with pricing or availability and they are checking into it. So anyone have any experience with this model or a similar model for existing zero clearance fireplaces? Any long term use info out there? I would love to put a free standing unit, but it is just not practical right now. I think I have the install information down, but always willing to learn more. If anyone can provide me with more info, different models, words of wisdom, I will certainly read, listen and learn. I just want to make sure I am getting into this with both eyes open. Sorry for the long winded post, and thanks for your time.
