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_logseneral_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.
