Can I use a wall-vented DV pipe to vent an unsealed gas log?

Hi All,

We are renovating a small old house and we are interested putting a gas fireplace of some sort in our very small library. Since have ample heat and a wood stove elsewhere, this fireplace would be strictly for ambiance and wouldn't be used a great deal.

Ideally we would like to use vented gas logs so that we could have an unsealed unit, but we could only accommodate a wall-vent -- not a top vent.

The introductory article on gas logs on this site (http://www.hearth.com/econtent/index.php/articles/gas_logs_general_introduction) suggests that it's possible to have an unsealed DV gas log unit, but I checked a few manufacturer sites and did not see that available. Am I missing something?

Thanks in advance for any thoughts.

Vented gas logs rely on natural draft to expel exhaust from the firebox. Direct venting a wall outside is a sure way to have draft issues. I would go with a low btu Direct vent unit if you cannot top vent- or vent-free (if its legal in your state) or electric fireplace.

I see. Do ventless logs also generally require a sealed glass enclosure?

It was this paragraph in the Gas Log Introduction post that made me think otherwise:

<<In the past decade, unvented log sets have become extremely popular, and the sales volume is approaching that of the Vented logs. The real revolution occurred when engineers figured out a way to produce a yellow flame with these sets, while still achieving a clean burn. Many folks are curious how you can burn a fuel in the home and have little on no effect on the air quality in the home. The easiest way to understand is to use your Kitchen Gas Range as an example. A range uses a special burner design to achieve a clean, smokeless flame. Unvented gas logs use a similar technology.

Well, not to worry. I may be the only one who's ever read it. Now I can stop puzzling over it and go order my gas stove. Thanks!
